My AC unit was located on the ground in a very undesirable area; in the direct path of my neighbor’s downspout. Sent pics to Thomas, got a reasonable estimate to raise the unit off the ground and bolt it to my foundation. The work was completed cleanly and efficiently at a very reasonable price! Extremely satisfied with their work!
Response from the owner: Thank you, Diane, for your wonderful 5-star rating; we appreciate your support!

I called on December 25th at midnight and started leaving a message and Thomas Hoffman the owner called me back almost immediately. He said he would come out the next morning between 8:00 and 10:00 am snd he was promptly on time. He fixed my problem and while he was there I decided to get an estimate for a new furnace and air conditioning unit. The price was very reasonable and the installers one of them being his son were both very professional very courteous, polite, arrived on time and finished the same day. I enjoy knowing that I now have the support of Thomas Hoffman heating and air conditioning along with the peace of mind that comes with owning a Trane. Nothing stops a Trane.Albert Koesterer

I called on a Monday morning as air conditioning was blowing warm air. They were able to come to my house very early afternoon and fixed the problem. Would highly recommend and will use them again.
Response from the owner: Becky thank you so much for your great review. We appreciate your business and your kind words.
This company is so responsive to me that I love them. They respond immediately and I trust them. It always cost me, but that is the nature of the beast. I haven’t been steered wrong yet. They are genuinely nice to work with and honest. I use their maintenance program as well. Highly recommend.
Response from the owner: Thank you for your kind words, we truly appreciate your trust in us and are glad to hear about your positive experience with our services.
Zac and Giovanni are always extremely polite, considerate and professional. We are thrilled to have the new A/C unit. Our unit was 18 years old and stopped working in the thick of 100 degree weather. Tom (the owner) came over within an hour (after hours) and bought us time by changing out some parts until we could have the new one installed. We’re very happy with Thomas Hoffmann A/C and Heating!
Response from the owner: Katie, we're delighted that Zac, Giovanni, and Tom were able to assist you promptly and effectively during the heatwave. Thank you for choosing Thomas Hoffmann A/C and Heating!
Couldn't be happier with our experience. Our AC stopped working after typical hours and they were the only "24/7" HVAC service who was able to come out same day. Not only were they fast, but they identified and fixed the problem immediately and did some preventative maintenance (and showed me how to do it) to prevent it from happening again. Will absolutely use them again in the future.
Response from the owner: We're so glad to hear about your positive experience, Hannah White! Thank you for choosing us and we look forward to helping you again in the future.
Caught in a bind one evening (no AC), I called for an appointment to get mine repaired. They came out the next morning, one half hour early! Within 30 minutes we back up and running!! Thank you, Thomas Hoffman. You are my guys!
Response from the owner: Thank you for choosing us, Sue! We're glad we could help you out quickly and get your AC up and running smoothly again! Thomas Hoffman and the team appreciate your kind words!
Fantastic experience! Our AC went out on a scorching Saturday evening. I wasn’t actually expecting anybody to get out that night, but when calling - I immediately got an answer, was on the schedule in 5 minutes, and Thomas showed up an hour later. He was honest, professional, and educational. Most importantly, I didn’t feel like he was cutting corners or trying to get in and out… a welcome contrast from most services these days. 6 stars out of 5, highly recommend.
Response from the owner: Thank you for sharing your experience, Andrew! We're so glad to hear that Thomas provided such honest and professional service for your AC needs. We truly appreciate your recommendation and look forward to serving you again in the future.
