Signs Your Furnace Needs Repair

Once you know what’s wrong with your furnace, the first step is to determine whether a simple repair will solve the problem or an entire replacement is necessary. Loud noises, slow heating, and high energy bills are all signs of a malfunctioning system. Fortunately, our expert furnace technicians can repair everything from small issues like dirty filters and faulty pilot lights to severe airflow imbalances and cracked heat exchangers. Contact us today and get expert, free troubleshooting on your furnace issues.

Signs you need a furnace repair include:

  • Dirty air filters
  • Restricted air flow in vents
  • Pilot control problems
  • Frequent cycling
  • Strange smells
  • Strange noises
  • Dirt and dust build-up
  • Carbon monoxide detected
  • The burner flame is yellow
  • Short cycles
  • Leaks around the unit

Common Furnace Symptoms We Fix

  • Short cycling, strange noises, cold spots — diagnostics + targeted repairs.
  • High bills or weak airflow — check filters, ducts, and blower performance; consider duct sealing.
  • Frequent breakdowns — we’ll advise whether a replacement is more cost-effective.

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.

Phil was outstanding! He diagnosed a problem that several other techs from a different company couldn’t figure out. He was so friendly and took the time to explain everything clearly. Highly recommend Phil from Southport!

Great experience on updating our HVAC systems to heat pumps/backup furnaces.
Ryan, Oliver, Andrew and Jacob (all installers for Southport) are wonderful, competent, and delightful young folks, who gave great service doing the physical upgrade of 2 older heat/ac systems.

I highly recommend Southport for your future HVAC upgrades. All the folks from the person doing the bids (Adam) to Manager (Jackson) to all the installers, are first class, professional and proud of where they work and what they do.

Losing AC in hot weather is never fun, but Southport made the whole process as painless as possible. They were quick to respond, easy to work with, and got everything moving fast when we really needed it.

From the initial quote to the installation of our new AC and furnace, everyone was friendly, knowledgeable, and professional. The communication was great, the work was done efficiently, and everything went smoothly.

We're extremely happy with the result and wouldn't hesitate to recommend them to anyone looking for HVAC work.

Got a furnace replacement and a/c unit install. Both work great. The hvac techs worked very hard but they were not so thrilled to be doing a full install on a friday. they made it clear by complaining within earshot for the whole 7 hours. So maybe consider not scheduling with them on a Friday and it may be a better experience for you. 5 stars

I purchased my furnace from Southport and needed service when my AC went out during a storm. Andrew,my service tech was fantastic! He explained everything, got the parts the same day, and had me up and running in no time at all! At his recommendation, I also purchased a surge protector and maintenance agreement so I can rest easier during storms. Thank you Andrew!!

I was referred to Southport by a co-worker. Their staff is super friendly and informed. The sales manager Nate was reasonable to work with. You can probably save a few hundred bucks going with a smaller company with less overhead, but I think the peace of mind that comes along while working with an established company like Southport, is much more important. They got me booked for an instilation appointment within two days of signing a contract! Their technicians were polite and did the best they could at keeping my carpeted basement clear of mud, considering the first few hours they were there was during a rainstorm. Whatever mess they made they cleaned up. The installation took longer then expected (about 10 hours) but there was a lot of work to be done, and the technician thanked me for my patience. He said it's nice to be able to take their time and make sure everything is installed perfectly! All and all, I had a positive experience, and highly recommend using Southport. Friendly and fast service at fair price!
