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!Michael L.Michael L. ★★★★★ Great service! They were able to fix my system the same day and on a weekend.

The staff who came out for the install could not have been more courteous and professional, the arrived when they were supposed to, they sent messages when they were on their way, and the completed all necessary work promptly. They then patiently walked me through pairing the new smart thermostat they installed and showed me how to use the app. They tested all of the systems and equipment before leaving and it has been working beautifully every since.
