Signs Your Furnace Needs Professional Repairs

With how busy life is, we’re helping you with some signs that your furnace needs repair. The signs include the following:

  • No heat: If your furnace cannot complete its purpose of heating your home, you need to get it repaired.
  • Infrequent cycling: While it’s a sign that your unit still has life, your cycles should be consistent. 
  • Leaking unit: No fluids should be building up around your system, so a leak indicates your unit is damaged. 
  • Odd noises: Furnaces are relatively quiet, allowing banging noises to signal trouble for your furnace.

Commons Furnace Repair FAQs

The length of an appointment will depend on what issues are found during our inspection. Unless a significant problem is found, repairing your furnace should take two to four hours.

It wouldn’t hurt to have your furnace inspected once a year. Annual inspections can allow technicians to discover and fix minor issues before they grow into a costlier repair.

The best way to know is by looking at your filter. If it’s layered in dust or debris, it’s likely that your filter has become clogged and needs to be replaced.

Theilmann was the only company out of two others, that told us about code requirements for our furnace being on the first floor. They did an amazing job with it being in a small spot and loved our dogs!

The Thielman group is great. They were right on time, efficient and did an excellent job. My only struggle is with the digital thermostat. I wish I had a better understanding of programming it. I would highly recommend this company to anyone.

Our old furnace quit. We called our old service provider, and the old furnace needed a very expensive replacement part. He also tried to sell us equipment we did not need. Being Costco members, I called Costco, and they forwarded our call to Thielmann. Jason called, and gave us a price for a new furnace. He came out the same day, and the price quoted over the phone was what we paid. The installation was scheduled, and we are very happy with the equipment and the service. Using Costco, we also got a nice rebate. Thanks.

Salesman came in and looked at both the furnace and air conditioner and we agreed to get new ones. He was very helpful. Also, the guys that came in and installed both were polite and good at their installation. Would recommend Thielmann.

Upon our first call to Theilmann Group with a furnace problem, thru to a new furnace and air conditioner. Everyone we encountered was professional and a pleasure to have in our home. This was not a planned purchase, but they made it as easy as possible. Highly recommend!!

Thielmann did a tremendous job replacing our Carrier furnace. They worked with us to make sure we were able to get the right product and even worked with Carrier on the issues we were seeing on our old furnace as it was failing sooner than it should have. The team was very professional and efficient. Great experience. We highly recommend them.

Stop shopping around and call Thielmann & Sons. Wayne, Chris and the team made it so easy, and made sure we understood all options and their impact to our home. Not only did they provide the information you look for in a home expert, but they gave us confidence that the price, timing, and install would go as planned, AND IT DID! They won't upsell you if you don't need it, and if they urge you one way it's because is it's the best option for you. Thanks to the whole team!

I've been using Thielmann Group for all my heating and air conditioning since I built my house 23 years ago. They have been great in emergency service and regular maintenance service. On time and very friendly staff. Would, and have, recommend them to anyone!
