They were timely, polite, professional and they saved us from too much sweating. In a field full of pompous and arrogant technicians, these guys take the time to explain what is wrong and how they are correcting it. Other folks just assume you are incompetent but these folks take the time to educate. Cannot recommend highly enough.

I’ve been using “THOMAS Hoffmann Airconditioning and Heating” for years now. We have a 30 +\- year old system that works perfectly for us. Although we’ve not had to use it yet, it is comforting to know they offer a 24 hour on call service. I really appreciate that the technicians don’t try to upsell us on anything. They’re a very professional, knowledgeable, and courteous, local-family owned and operated business. I’ve also found their pricing to be very fair and by”fair” I don’t mean “cheap” but reasonable… especially for the quality of service provided by THOMAS Hoffmann HVAC. I love supporting smaller family owned business and this one is top-notch! Thank you guys!
Response from the owner:Thank you so much for your continued support and kind words, Mari! We truly appreciate your loyalty and are glad to hear about your positive experiences with our services. We look forward to continuing to provide you with top-notch service in the future.

Just had our annual service on our A/C. The technician, Giovanni, was very professional, friendly, thorough and spent time explaining what all he did and what his findings were. Couldn't be happier. I HIGHLY RECOMMEND THOMAS HOFFMAN AIR CONDITIONING AND HEATING.
Response from the owner:Terry, we're so grateful for your kind words and for recommending us! We're thrilled to hear that you had a positive experience with our technician during your annual furnace service. Thank you for choosing Thomas Hoffman Air Conditioning and Heating!
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
Response from the owner:Albert thanks so much for your kind reviews and your business. We truly appreciate it!!!
I made another service call years after my last review. Once again, Tom did not disappoint. He identified the cause of my newly purchased system installed by another HVAC company. He explained it so simple and easy to understand without the technical jargons. I just wished I had purchased the new equipment from Tom instead of saving a few hundred dollars from his competition.
Response from the owner:Thank you, J, for your kind words! We're glad to hear that Tom was able to assist you so effectively and make everything easy to understand. We appreciate your continued trust in our services and hope to help you again in the future!
I've used these guys twice now and their response time is great, they are friendly, informative, and most importantly, effective. I'm calling these folks every time my furnace sounds weird.

Very fast considering the weather we were having tonight. Really appreciate it for my mom. Thank you so much!
Response from the owner:Thank you, Felicia! We're glad we could help quickly, especially for your mom. Your appreciation means a lot to us!
Nick was on he way to our house when I had to cancel my appointment for service. Nick was very understanding and professional about it. While we didn't get to utilize him, I have no doubt he'd have been just as professional in his job.
Response from the owner:Thank you for your kind words. We appreciate your understanding and are glad to hear that Nick made a positive impression. If you ever need our services in the future, don't hesitate to reach out.
