Simple fixes land near the lower end. Complex gas or tankless issues trend higher. Emergency service after-hours may add a premium. What drives your total: 1. Unit type - Standard tank models are generally cheaper to repair. - Tankless units require specialized service and can cost more. 2. Fuel type - Electric parts are often less expensive than gas components. - Gas troubleshooting may include venting or combustion checks. 3. Part and labor time - Some parts are fast to swap. - Hard-to-access units or code updates increase time on site. Cardinal technicians always perform an on-site inspection before recommending repair or replacement. Expect clear pricing and step-by-step options. ## Common Repairs and Typical Price Ranges Below are realistic ranges for the Greater Madison market. Final pricing depends on model, access, and condition. 1. Heating element or igniter: $120–$350 - Electric heaters often need new elements. - Gas units may need igniter or pilot assembly work. 2. Thermostat or gas control valve: $150–$450 - Restores temperature accuracy and safe operation. 3. Anode rod replacement: $120–$300 - Protects your tank from corrosion and can add years of life. 4. Temperature and pressure relief valve: $140–$280 - A critical safety device that prevents dangerous pressure build-up. 5. Leaking supply lines or fittings: $150–$350 - Replacing flex lines, valves, or dielectric unions. 6. Dip tube replacement: $150–$300 - Fixes lukewarm water caused by cold-water mixing in the tank. 7. Flushing and sediment removal: $120–$250 - Restores capacity and efficiency, especially with hard water. 8. Tankless descaling service: $169–$299 - Chemical flush is essential for longevity in hard-water homes. If your tank is rusted or leaking from the body, repair is not safe or cost-effective. Replacement is the right move. ## Signs Repair May Not Be Worth It These are clear indicators that replacement will likely save money. 1. The tank itself is leaking - Internal tank leaks cannot be repaired safely. 2. Advanced age - Many local homes replace water heaters every 10–15 years. If yours is near that window, compare repair costs against replacement. 3. Repeated breakdowns - Multiple visits over a short time suggest a failing unit. 4. Rust, loud rumbling, or metal shavings in drained water - These point to heavy corrosion and sediment damage. Our team provides side-by-side cost comparisons. We help you choose the right size and energy source for your home and hot water habits. ## Labor, Permits, and After-Hours Pricing Labor typically ranges from $120 to $180 per hour for licensed plumbing work in our region. Some repairs have flat-rate pricing based on the task and parts required. After-hours emergency service can include an additional fee. We disclose this upfront during scheduling. Permit needs vary by city and scope. Repairs that alter gas lines, venting, or electrical circuits may require inspection. We handle permits and coordinate inspections when needed. That protects your warranty, insurance, and resale value. ## Tank vs. Tankless: What Changes the Price Tank models: - Parts are widely available and usually lower cost. - Sediment buildup is common with Dane County hard water. - Annual flushing helps prevent element failure and temperature issues. Tankless models: - Require periodic descaling to maintain performance. - Diagnostics can take longer due to sensors and control boards. - Venting, gas supply, and condensate management must be correct to avoid error codes. Cardinal services both types. Our licensed, background-checked team has experience with major brands and local code requirements. ## The Hidden Cost of Hard Water in Greater Madison Hard water speeds up scale formation inside tanks and on tankless heat exchangers. Scale insulates heating surfaces and reduces efficiency. It also shortens the life of elements, thermostats, and valves. Prevention tips for our area: 1. Flush tank water heaters annually. Twice a year if you hear rumbling. 2. Descale tankless models every 12 months, or per manufacturer guidance. 3. Consider an anode rod check at the 3–5 year mark. 4. Ask about water treatment if you have frequent element failures. These small steps reduce repairs and help your system reach its expected lifespan. ## Repair vs. Replace: How to Decide When we visit your home, we weigh the following: - Age and condition - Current repair cost vs. likely future repairs - Energy efficiency and utility savings - Safety concerns and code compliance - Your hot water demand and family size A practical rule of thumb: If a repair is over half the cost of a new system and the unit is near 10 years old, replacement is often the smarter financial choice. We will show you both scenarios, including available rebates and financing. ## What a Professional Diagnosis Includes Expect a structured process that protects your home and budget: 1. Safety check - We verify gas shutoff, venting, and electrical connections. 2. Visual inspection - We look for rust, leaks, scorch marks, and loose fittings. 3. Component testing - We test elements, thermostats, igniters, and sensors. 4. Flow and temperature testing - We confirm delivery temperature and recovery performance. 5. Water quality notes - We check for signs of scale, sediment, or discolored water. At the end, you receive a clear explanation, photos if helpful, and written options. No guesswork. ## How Emergency Service Affects Price Cold shower at 6 a.m. or a leak at 10 p.m.? True emergencies need quick action. After-hours dispatch costs more due to staffing and parts access, but it limits water damage and downtime. We are available 24/7 for hot water issues. The technician will explain any after-hours fee before work begins. ## Cost Scenarios You Can Use 1. Electric tank, no hot water - Diagnosis finds a failed upper element. Replace element, check wiring, flush sediment. Typical total: $220–$350. 2. Gas tank, warm but not hot - Pilot lights but fails. Igniter and thermocouple replacement plus vent check. Typical total: $250–$450. 3. Tankless unit with error code - Scale detected. Perform chemical descale, inspect inlet screen, reset sensors. Typical total: $169–$299. 4. Leaking T&P valve - Replace valve, verify expansion tank, test temperature. Typical total: $140–$280. Use these ranges to budget. Your final estimate will be based on model, access, and parts. ## Ways to Lower Your Repair Bill - Catch small issues early with annual maintenance. - Join a maintenance plan for priority service and member pricing. - Keep the area around your heater clear for faster service. - Know your model and serial number for quicker parts matching. - Ask about coupons and financing before the visit. Cardinal offers service and maintenance plans that keep systems efficient and reduce surprise breakdowns. ## Why Homeowners Choose Cardinal for Water Heater Repairs - Local experience since 1984 and 30+ years of service. - BBB accredited with strong community awards, including Best of Madison. - Licensed, background-checked technicians who protect your home with shoe covers and drop cloths. - Full-service contractor for plumbing, HVAC, and electrical. - 24/7 availability for hot water emergencies. - Honest repair-or-replace guidance and clear pricing.

Most repairs fall between $180 and $650, depending on part, labor time, and unit type. Electric parts are often cheaper. Gas and tankless diagnostics can take longer. After-hours service may add a premium. We provide a written estimate before work starts. ### Is it better to repair or replace a 10-year-old water heater? If your unit is near 10 years and the repair exceeds half the cost of a new heater, replacement often makes sense. Consider efficiency, warranty, and your hot water demand. Leaking tanks should always be replaced for safety. ### How often should I flush my water heater in Dane County? Flush tank models annually to reduce sediment. With hard water or rumbling noises, consider every 6 months. Tankless units should be descaled about every 12 months, or as the manufacturer recommends. ### Do I need a permit for water heater repairs? Simple part replacements usually do not. Work affecting gas lines, venting, or electrical circuits may require permits and inspection. We handle any needed permits and coordinate with your city. ### How long does a typical repair take? Most same-day repairs take 60 to 180 minutes once parts are on site. Tankless diagnostics or multiple component failures can extend the visit. Your technician will provide an estimated timeline after diagnosis. ## Conclusion Water heater repair cost depends on unit type, part, and labor time.

Stoughton WI Water Heater Replacement Costs - Plumbing Guide

*Estimated Read Time: 12 minutes* If you are searching for water heater replacement cost in Madison or nearby, you are likely facing cold showers and surprise bills. This guide explains real-world water heater replacement cost so you can plan with confidence. We break down tank vs tankless, parts, permits, labor, and how to save without cutting corners. First-time customers can also tap a limited-time coupon below. ## What Drives Water Heater Replacement Cost Water heater replacement cost depends on five main factors: 1. Equipment type and size - Conventional tank: common sizes are 40 to 50 gallons for most homes. - Tankless: heats water as it flows, offering endless hot water and small footprint. 2. Fuel type - Natural gas or propane units typically cost more upfront than electric but can cost less to run. 3. Venting and code upgrades - Replacing like for like is usually simpler. Conversions may require new venting, gas piping, or electrical work. 4. Installation complexity - Tight closets, long vent runs, or relocating the unit add time and materials. 5. Local permits and inspections - In Wisconsin, water heaters must meet DSPS Plumbing Code SPS 381-387. Relief valve discharge piping, venting, and combustion air are common inspection points. Pro tip: The Department of Energy notes water heating is typically the second largest energy load at home, often around 18 percent of usage. Choosing the right efficiency level can pay you back every month. ### Typical Price Ranges in Greater Madison These are common ranges we see across Madison, Sun Prairie, Middleton, and nearby: - Standard electric tank, 40–50 gal: replacement often lands in the lower range for equipment and labor. - Standard gas tank, 40–50 gal: generally mid-range due to venting and gas connections. - High-efficiency gas tank or power-vent: adds cost for advanced venting and condensate management. - Tankless gas: higher upfront for the unit and potential gas line and vent upgrades, but delivers energy savings, long lifespan, and endless hot water. Every home is different, so we perform an on-site inspection before recommending repair or replacement. Many callers discover they only need a part and tune-up. ## Tank vs Tankless: Cost, Efficiency, and Lifespan When homeowners compare replacement options, three variables matter most: upfront cost, operating cost, and long-term value. - Tank water heaters - Upfront: lower purchase and install cost, especially for like-for-like swaps. - Operating: heat loss from stored water can increase utility bills. - Lifespan: commonly 10–15 years in our climate and water conditions. - Best for: budget-conscious replacements and households with moderate demand. - Tankless water heaters - Upfront: higher equipment and installation cost. May need gas line resizing, venting changes, or a dedicated electrical circuit. - Operating: heats only when you open a tap, so standby loss is minimal. Can lower monthly bills. - Lifespan: often longer than tanks with proper maintenance. - Best for: endless hot water, smaller mechanical closets, and households with back-to-back showers or large tubs. Cardinal installs both electric and gas systems and can compare your 10-year ownership cost, not just today’s bill. ## Line-Item Breakdown: Where Your Money Goes A transparent estimate should show where each dollar lands. Here are the typical line items on a professional replacement: 1. Equipment - The water heater itself plus manufacturer-required accessories. 2. Materials - Expansion tank if required by local code, vent pipe, gas flex, dielectric unions, shutoff valves, and T&P discharge piping. 3. Labor - Removal and disposal of the old unit, installation, start-up, and code compliance. 4. Permit and inspection - City or county permit fees and scheduling the inspection when required. 5. Warranty and documentation - Registration for extended manufacturer coverage and our workmanship guarantee. Small detail, big safety: The temperature and pressure relief valve must discharge to an approved drain with proper piping. This is a code-critical item your inspector will check. ## When Repair Makes More Sense Than Replacement Many homeowners call us expecting a full replacement, but a repair can be the smart move when: - The unit is under 8 years old and otherwise in good shape. - You have no tank leaks, only symptoms like pilot issues or failed heating elements. - Energy bills did not spike, and there is no rust or discolored hot water. - The issue is localized, like a bad thermostat, anode rod, or burner assembly. We start with an in-home inspection and price the repair alongside replacement so you can compare apples to apples. ## Red Flags That Point To Replacement Replacement becomes more cost-effective or necessary when you notice: - Water pooling around the tank or visible corrosion on the body. - Rust-colored water from hot taps. - Frequent resets, noisy operation, or rising energy bills. - The heater is 10–15 years old and out of warranty. If your tank is leaking from the body, replacement is the only safe option. ## Special Considerations for Madison and Surrounding Areas Local conditions drive design choices: - Hard water in parts of Dane County accelerates scale on elements and heat exchangers. This shortens life and hurts efficiency. - Tight mechanical rooms in older homes can favor tankless units for their smaller size. - Cold incoming water during winter increases recovery time. Right-sizing the BTU input or tank capacity avoids morning cold showers. - Wisconsin DSPS Plumbing Code SPS 381-387 applies to replacements. Proper venting, combustion air, and T&P relief piping are not optional. Our full-service team handles plumbing, gas, electrical, and venting in one coordinated visit. ## The Cost of Doing It Right vs Doing It Twice Cut-rate installs can look attractive until you factor in callbacks and utility waste. The most common shortcuts we fix include: - Reusing undersized venting on new higher-efficiency models. - Skipping an expansion tank where code or water conditions require it. - Improper gas flex routing or lack of drip leg. - No sediment trap on gas lines feeding tankless units. A correct installation saves on energy, reduces carbon monoxide risks, and protects your warranty. ## How Cardinal Builds Your Estimate We keep it simple and transparent: 1. In-home evaluation - We inspect your heater, gas and water lines, venting, and electrical. We also confirm clearances and drain access. 2. Options and pricing - You will see repair and replacement choices with good, better, best options. We include all necessary code updates in the price. 3. Same-day or next-day installation - Our stocked trucks and on-call team cover Madison, Sun Prairie, Middleton, Deforest, Waunakee, Verona, McFarland, Stoughton, Oregon, and Cottage Grove. 4. Clean, safe completion - Shoe covers, drop cloths, haul away, and start-up testing are included. We register warranties for you. 5. Follow-through - We review maintenance to protect your investment and help you choose our Cardinal Care Club if ongoing priority service is important to you. ## Operating Costs, Efficiency, and Payback Efficiency matters because water heating can be a double-digit share of your utility spend. Here is how to think about the long-term cost: - Fuel rates - Natural gas vs electricity pricing in your neighborhood will tilt the payback math. - Usage profile - A family of five taking back-to-back showers benefits more from tankless efficiency than a one-bedroom condo. - Maintenance - Annual tank flushes and tankless descaling maintain efficiency and extend life. Skipping maintenance increases energy waste. If you plan to stay in the home 7 to 10 years, the total cost of ownership often favors higher-efficiency models. ## Maintenance Costs That Protect Your Investment Budget a small annual allowance to keep performance high and avoid surprise failure: - Tank heaters - Flush once per year. Replace anode rod every 3 to 5 years depending on water quality. - Tankless heaters - Annual chemical descale and flush, plus filter cleaning. This keeps heat exchangers at peak efficiency. Members of our Cardinal Care Club receive routine maintenance and priority service, which helps catch small issues before they become major problems. ## Financing, Warranties, and Ways To Save Smart homeowners stack these savings to lower the net cost of replacement: - First-time customer coupon on water heater services. - Financing for larger projects so you can choose the best long-term option now. - Maintenance discounts through the Cardinal Care Club. - Utility rebates when available for high-efficiency models. We help you identify any local incentives. We apply credits on your invoice so you do not chase paperwork. ## Emergency Replacement: What Changes In The Quote When you need hot water today, the plan shifts: - After-hours dispatch and 24-7 availability ensure fast response. - Temporary safety steps, such as shutting off gas and water, may be needed before we arrive. - We often complete same-day replacements with stocked models. Special-order equipment may require a short interim solution. Your estimate will still show parts, labor, code items, and warranties so you see exactly what you are paying for. ## What To Do Before Your Appointment A few simple steps make the visit smooth and fast: 1. Clear a path to the water heater and nearby utility areas. 2. Know where your main water shutoff and gas shutoff valves are. 3. Note any recent symptoms like rusty water, banging noises, or pilot outages. 4. Decide if you want to discuss tankless vs tank options so we can bring both prices. We will take it from there and leave the space cleaner than we found it. ## Why Homeowners Choose Cardinal - One-stop contractor for plumbing, HVAC, and electrical.

Most replacements fall into a predictable range, with gas units slightly higher than electric due to venting and gas work. Final price depends on code items and site conditions. ### Is tankless really worth the higher upfront cost? For homes with high demand or limited space, yes. Tankless offers endless hot water, better efficiency, and a longer lifespan. Maintenance is key to protect payback. ### Do I need a permit for a water heater replacement in Madison? Permits are often required, especially if venting, gas piping, or electrical changes are made. We pull permits and coordinate inspection for you. ### How long does installation take? Like-for-like tank replacements often complete in 3 to 5 hours. Tankless or complex code upgrades can extend to a full day. ### Should I repair or replace my old water heater? If it is under 8 years old and not leaking, repair can make sense. Tanks with body leaks or units 10–15 years old typically warrant replacement. ## Bottom Line A clear water heater replacement cost starts with the right scope, code-compliant parts, and a trustworthy installer.

Fitchburg, WI Water Heater Not Heating? 5 Fixes

*Estimated Read Time: 11 minutes* Woke up to a cold shower and a water heater not heating? You are not alone. Whether you own a gas, electric, or tankless unit, five issues cause most no‑hot‑water problems. In this guide, you will learn quick checks you can do safely, how to fix common faults, and when to call Cardinal for a fast, 24/7 repair in Madison, Sun Prairie, and nearby cities. First‑time customers can also save with our limited coupons below. ## Why Your Water Heater Is Not Heating: Quick Diagnostics Before you panic, take a minute to observe. A few safe checks can narrow the cause. 1. Confirm power or fuel: - Electric: Check the breaker and the water heater switch. Reset once. - Gas: Make sure the gas valve is open. Look for a lit pilot or active ignition. 2. Listen and look: - Any hissing, popping, or rumbling often points to sediment buildup. - Drips around fittings or rust on the tank can signal leaks or age. 3. Check delivery: - Try hot water at two fixtures. If one is hot and one is cold, you may have a mixing valve or fixture issue. 4. Read the age: - Most tank models are ready for replacement around 10 years. Tankless models can last up to about 20 years with proper maintenance. If these checks do not restore hot water, move into the five most common causes below. ## 1. Tripped Power, Pilot, or Gas Supply Issues Loss of electricity or fuel is the top reason a water heater stops heating. For electric tanks, a tripped breaker or high‑limit reset button will cut power to the elements. For gas models, a closed gas valve, extinguished pilot, or failed igniter leaves the burner offline. What you can try safely: 1. Electric units - Inspect your main panel. If the water‑heater breaker is tripped, turn it fully off, then back on once. - Press the high‑limit reset on the upper thermostat behind the access panel. If it trips again, call a pro. 2. Gas units - Verify the gas valve at the tank is parallel to the pipe. Relight the pilot per the manufacturer label if you are comfortable, or call us. - For electronic ignition, power cycle the unit. If the igniter clicks but never fires, you may have a gas delivery or sensor issue. 3. Tankless systems - Ensure the condensate line is clear and the intake/exhaust are not blocked. Many units lock out when airflow is restricted. Why call a pro: - Repeated breaker trips, gas odors, or ignition lockouts point to deeper problems like shorted elements, failed gas valves, or control board faults. Cardinal’s diagnostic‑first approach saves time and avoids parts you do not need. Our licensed and background‑checked technicians are on call 24/7 for Madison‑area emergencies. ## 2. Failed Heating Elements or Burner Problems If power and fuel are present but water stays cold, the components that make heat may be failing. Electric tanks use upper and lower elements. When one burns out, you may get lukewarm water or a very short supply. Gas tanks rely on a clean burner flame and proper combustion. Flame rollout, dirty burners, or a weak thermocouple can stop heating. DIY‑friendly checks: 1. Electric element symptoms - Hot water runs out fast or never reaches set temperature. - Upper element failure often means no hot water. Lower element failure means limited supply. 2. Gas burner symptoms - Yellow, lazy flame or soot buildup points to poor combustion. - Pilot goes out often or thermocouple will not hold. Pro solutions we perform: - Replace failed elements, thermostats, or thermistors. - Clean or replace a thermocouple/thermopile, clean the burner, and verify gas pressure. - For tankless, descale the heat exchanger and verify flame sensor calibration during tune‑up. When it pays to repair vs replace: - If the tank is under 10 years old and the tank itself is sound, parts replacement is often cost‑effective. - If the system is older than 10 years and shows multiple issues, replacement can prevent repeat failures and lower energy use. ## 3. Thermostat Miscalibration or Mixing Valve Issues Thermostats and mixing valves control temperature. If they drift or stick, you can get cold or inconsistent water. Common signs: - Water temperature swings from hot to cold during a single shower. - Stable temperature at one fixture but not another. - Tankless unit throws temperature or flow error codes. What you can do: 1. Verify setpoint - Most homes find 120 degrees Fahrenheit comfortable and safe. Higher setpoints may risk scalding. 2. Balance fixtures - If only one bathroom is affected, the issue may be the tub/shower mixing valve cartridge. Replacing the cartridge often restores steady temperature. 3. For tankless - Clean inlet water and air filters. Remove any debris screens at the fixtures. Confirm minimum flow rate is met by opening the tap further. Professional fixes: - Calibrate or replace tank thermostats. Update anti‑scald mixing valves to modern standards. - For tankless, adjust gas pressure, verify venting, and update firmware where supported. Why it matters: - Miscalibrated controls waste energy and shorten equipment life. Proper control settings also reduce the risk of bacterial growth from lukewarm storage. ## 4. Sediment Buildup Reducing Heat Transfer Minerals settle to the bottom of tank water heaters. Over time, this crust insulates the water from the heat source and causes popping or rumbling. The result is longer recovery times, higher bills, and lukewarm water. Homeowner steps: 1. Flush the tank - Turn power or gas control to off. Connect a hose to the drain valve. Drain several gallons until clear. Refill and restore power. 2. Replace the anode rod - If your water heater is several years old, a new anode rod helps limit corrosion and sediment. When a pro is best: - If sediment is heavy, the drain valve can clog. We use sediment‑safe procedures and can replace a faulty valve on site. - For tankless systems, scale builds inside the heat exchanger. A chemical descale and flush restores efficiency and temperature stability. Maintenance equals savings: - Regular water heater maintenance can extend the life of your unit and improve efficiency. Cardinal offers comprehensive maintenance services, including tankless descaling, to keep your system at its best. ## 5. Age, Leaks, and Capacity Limits Sometimes the problem is not a repairable fault but the limits of the system. What age tells you: - Many conventional tank systems are often due for replacement after about 10 years. Tankless models can last up to about 20 years with proper maintenance. Leak and rust warnings: - Active leaks, rust‑colored water, or corrosion at the base of the tank suggest the glass lining has failed. Repair is not cost‑effective when the tank itself is compromised. Capacity shortfalls: - A 40‑ or 50‑gallon tank may not keep up with a larger family, multi‑head showers, or back‑to‑back laundry cycles. Recovery time matters in winter when inlet water is colder around Dane County. Best next steps: - If your tank is undersized or aging, we will price both like‑for‑like replacement and tankless options. Tankless provides energy savings, a smaller footprint, and an endless supply of hot water. ## Repair vs Replacement: How We Decide on Site Cardinal believes in diagnostic‑first recommendations. Our technicians inspect before recommending repair or replacement, so you get the right solution for your home and budget. We evaluate: 1. Age and condition of the tank or heat exchanger. 2. Severity and frequency of faults or error codes. 3. Energy consumption and recovery time. 4. Safety, including venting, gas pressure, and electrical integrity. 5. Hot water demand for your household. If repair is wise, we fix. If replacement will save you repeat visits and energy costs, we explain why and show options. You stay in control. ## Tank vs Tankless: Which Solves No‑Hot‑Water Problems Best? Both can deliver reliable hot water when sized and maintained correctly. The choice depends on your home and goals. Tank water heaters: - Pros: Lower upfront cost, simpler installation, familiar operation. - Cons: Limited storage, slower recovery, more sediment risk. Tankless water heaters: - Pros: Energy savings, compact size, endless hot water, longer lifespan with maintenance, and often less routine maintenance. - Cons: Higher upfront cost, requires proper gas line sizing, venting, and regular descaling. Cardinal installs and services electric and gas water heaters, including tankless models. Proper installation and ongoing maintenance are essential to performance and lifespan. ## Safe DIY vs When to Call Cardinal DIY‑safe actions: - Reset a tripped breaker once. - Relight a pilot only if you are comfortable and there is no gas odor. - Flush a few gallons to reduce sediment if valves are operable. - Clean tankless filters and check condensate drains. Call us immediately for: - Gas smell, scorch marks, or repeated ignition failure. - Water around the base of the tank or active leaks. - Breakers that trip again after a reset. - Error codes you cannot clear on a tankless system. We provide 24/7 emergency service. That means if your water heater quits on a freezing January morning in Madison or Sun Prairie, a licensed pro can be on the way fast. ## Preventative Maintenance That Actually Works A little maintenance goes a long way toward steady hot water and lower bills. What our plans include: 1. Annual safety and performance inspection. 2. Tank flush, anode inspection, and thermostat calibration. 3. Tankless chemical descale and heat‑exchanger cleaning. 4. Venting, combustion, and electrical checks. Why it pays: - Fewer breakdowns and more consistent temperature. - Lower energy use due to clean heat transfer. - Longer system life. Many tank models warrant attention after about 10 years, while well‑maintained tankless units can serve for up to about 20 years. Cardinal offers service and maintenance plans to keep your water heater efficient year‑round. ## Local Expertise Matters Homes around Madison, Sun Prairie, Fitchburg, Middleton, and Waunakee range from older bungalows to new builds. That means everything from legacy venting to high‑efficiency setups. As a full‑service contractor, we handle plumbing, HVAC, and electrical in one visit when needed. That reduces delays and makes sure the gas line sizing, electrical circuit, and venting are all correct for your water heater. Two facts to trust: - We provide 24/7 emergency response backed by licensed, background‑checked technicians. - Our long record of service has earned BBB accreditation and local Best of Madison and Best of Sun Prairie awards. ## Cost, Timing, and What to Expect Every job starts with an on‑site inspection so you get a precise diagnosis. Typical timelines: - Same‑day repair for common parts like elements, thermostats, or thermocouples. - Next‑day replacement for standard tank units, often same day when in stock. - Tankless installation is typically completed in one day once gas and venting are verified. Budget guidance: - Minor repairs cost less than replacement and can restore performance quickly. - If your tank is over 10 years old or leaking, replacement protects your home and may lower utility costs. Ask about financing and current coupons for first‑time customers and maintenance services. ## Step‑By‑Step: Get Your Hot Water Back 1. Do the safe checks: breaker, pilot, and obvious leaks. 2. Try one reset only. Note any error codes. 3. Call Cardinal at (608) 291-6473 or book online for a diagnostic. 4. We inspect, then explain repair vs replacement with clear pricing. 5. Approve the plan and get same‑day relief in most cases. ## Special Offers for Water Heater Service - Save $25 on water heater services. Use code FIRST25 before 2025-11-05.

All work done professionally and quickly." > –Chris G., Water Heater Service ## Frequently Asked Questions ### Why is my water heater not heating after I reset the breaker? A breaker that trips again points to a failed heating element, shorted wiring, or a bad thermostat. Do not keep resetting. Call a licensed pro to test and replace faulty parts safely. ### How often should I flush my water heater? Once per year is a good rule for most homes. Flushing removes sediment that insulates heat and causes rumbling. Tankless units should be descaled annually to keep the heat exchanger efficient. ### Is 120 degrees a good temperature setting? Yes. A 120 degree Fahrenheit setpoint balances comfort, energy savings, and safety. It is hot enough for hygiene while reducing scald risk and energy use for most households. ### When should I replace instead of repair? If the tank is over 10 years old, leaks, or has repeated failures, replacement is usually smarter. For tankless units with heavy scale or control board faults, a pro can compare repair parts vs replacement. ### Do you offer emergency water heater service? Yes. Cardinal provides 24/7 emergency service across Madison, Sun Prairie, and nearby cities. Call (608) 291-6473 for immediate help. ## Final Takeaway Most no‑hot‑water headaches come down to power or fuel issues, failed heating parts, control problems, sediment, or age.

Water Heater in Greater Madison | Cardinal Heating & Air Conditioning

Q: What should I do if my water heater is leaking from the bottom?

A water heater leaking from the bottom usually points to a failing tank or lower fitting and you should shut it down and call for service. Most often, internal corrosion causes the breach, and units around 10–15 years old are more likely to need replacement after inspection. We provide 24/7 help and will inspect the system to confirm if a repair is possible or if replacement is the safer, longer-term fix; we handle these calls across the greater Madison area, including the Deforest region. If you can do so safely, take these steps: - Turn off power: switch the electric breaker off, or set the gas control to off. - Close the cold-water shutoff valve on top of the tank. - Keep away from standing water near outlets or cords, and move valuables to reduce damage. - Call for urgent service if leaking is active or worsening. A steady bottom leak usually means replacement is likely, so act quickly to limit water damage. Updated: 2026-04-01 Need help in Deforest, WI? Call (608) 291-6473 or book online.
