What to Expect from Our Madison Furnace Repair Team
Our Madison furnace technicians start every visit with a quick conversation about what you’re seeing, from strange smells to rising energy bills. Then we get right to work diagnosing the problem so you know exactly what’s going on with your system.
Here’s how a typical repair visit works:
-
Arrival and safety check: We arrive during your scheduled window, confirm the issue, and verify that your gas, electrical, and venting connections are safe.
-
Up-front options: After testing your furnace, we explain what we found in plain language and share repair options with pricing before any work begins.
-
Focused repair work: Your technician starts the approved repair and keeps you updated as the job moves along.
-
Clean-up and next steps: We tidy the work area, review what was fixed, and answer questions about filter changes, thermostat settings, and future maintenance.
Common Furnace Problems
The severity of the problem and the age of your furnace will determine whether or not your home or business requires a new furnace installation. In many cases, our experienced heating contractors can repair or replace broken furnace parts. However, if your unit is over 12 years old, it may be time to consider installing a new furnace. The good news is that our Wisconsin furnace techs will do everything in our power to save your system and help your furnace function at peak efficiency for as long as possible.
Common furnace problems include:
-
Imbalanced airflow: If one room in your home is warm while others are cold, your furnace might have imbalanced airflow. That’s why, instead of trying to fix this issue yourself, it is better to call an experienced professional.
-
Leaky ducts: Broken and cracked ductwork could cause warm air to leak out of your home. Not only is this a waste of money, but it also forces your furnace to work overtime to compensate for the lost heat, thereby driving up your energy costs.
-
Faulty pilot light: Your furnace’s pilot light can fail for a number of reasons. It could be a damaged thermocouple, clogged gas pipes, or even a draft. Fixing the pilot light could require a new part or all new piping.
-
Broken blower motor: While replacing your furnace’s blower motor may sound like a simple process, it involves more than just swapping out a single part.
-
Cracked Heat Exchanger: A cracked heat exchanger reduces your furnace’s efficiency and allows dangerous gases, such as carbon monoxide, into your home.
