Sigman Heating and Air Conditioning, Inc.

I had a great experience working with the Sigman team, from initial AC repair to installing a whole new system (old heating and air systems were over 15 years old and started giving me frequent problems). From the quoting conversation to actual service and install, the entire team was professional, on time, and very entertaining (I had a great crew who was funny and kept me laughing throughout the day)! Looks like I have my heating and cooling team set for life now!

These guys were extremely responsive as our current furnace had stopped working and needed to be replaced. They came the same day we called and gave us an estimate. Then returned the next day to complete the installation.

The service technicians were very professional and did a great job of cleaning up the work area afterward.

Bob, Jake, Johnathan and Jerry were fantastic and very professional I can't believe they got the work done in one day. They took the time to explain what they were going to do and when done walked me through the new system. I will recommend Sigman to all my family and friends.

We had Sigman Heating and Air Conditioning install new furnace and air units just two days ago and both products and service were super!
Craig, Tony and Jason (just to name a few on the crew), were great at explaining the process, answered all questions and cleaned up the entire debris as well. We are well satisfied with Sigman and would recommend them without hesitation! Excellent job!

I called Sigman because I needed a inducer motor for my furnace, now I'm not disappointed in the service per say just the pricing of the item I needed. The sales guy was very nice and attentive to what I was requesting . The part I needed they stated they would have to order it and it would be about a week, pretty standard, but my family needed heat sooner than later. Their price was between 4 and 500$. I did my own research and found what I needed for 70$, so why the mark up? Sigman is nice but you'll pay for it in my opinion. I got the part I needed in two days doing my own research.

I bought a house in the historic area of Belleville to restore and called Sigman on recommendation from a relative. They came out and collected the necessary information to design a new system for the property. I never received a bid or any information on a system. I reached the man who was to be designing a system, (after 2 months) and he promised he would have something the following week. I did not hear from him. I have called numerous times with no return call. Why?? very disappointing and unprofessional. If you do not want or can not perform the service-be professional and return a call.

It's great to find a contractor that calls when they say they're going to call, shows up when they say they're going to show up and does a professional job! On time, reliable, and professional! We just had them install a new AC unit. Highly recommend!

I paid Sigman $294.00 for a maintenance agreement, which included summer and winter cleanings. The unit was supposed to be cleaned, including the condensate drain. Ten weeks after the summer service call, the drain was clogged, causing damage to the ceiling and floor. Two calls to Sigman were never returned to explain how such a unit (that they installed) could get clogged within 10 weeks of being cleaned. Since it was a holiday weekend, I signed the invoice, paid an extra $252.00 for the 2nd cleaning, thinking I could resolve the issue with management after the holiday. The company will not respond to any of my complaints, leaving a very unsatisfied customer. I will never trust them again to service or install heating and cooling.

I called Sigman Heating & Air Conditioning to fix my air conditioning unit. They were at my house within the hour after I called them. The technicians were very professional, clean, and friendly. They took care of the issue, all at a very reasonable price. Thanks for the excellent service, will definitely be recommending you!

Zack service tech came out during the worst winter storm of the year to get our heat system going. He found some issues and suggested some things to have our electrical breaker looked at. Definitely recommend Sigman and how fast they were able to come to my home. Thank you so much!
