Denise F.

We had a Mini-Split Ductless System installed in our garage by Sentry Heating and Air – Jamie and James were top notch in their work installing, clean-up and instructions on how to use the Carrier Mini-Split. We would highly recommend them.

Ryan B.

Jacob and Louis came out to diagnose some HVAC issues we had been having and they were fantastic – they found and diagnosed the problem and did an outstanding job educating me when I had lots of questions on the problem and system. 10/10 would call them again for diagnosis and a service call!

Dave K.

On time, courteous & professional! James and Jamie were fantastic.Highly recommend using them.

Joseph J.

I recently had a PRV replacement and water heater replacement. First of all, the estimate was a very reasonable price compared to another competitor. Devonn and Ryan did the install and did a tremendous job. I was very impressed by Devonn’s knowledge and willingness to take the time to explain and answer any questions I had. I would definitely recommend them to anyone.

Jackie T.

We just wanted to spotlight Hannia for her amazing customer service! She was professional, friendly, and very knowledgeable while repairing the control board on our furnace. She explained the issue clearly and made sure everything was working properly before leaving. We highly recommend Hannia!

Kevin A. has been out several times and is always a great ambassador for Sentry. He is very courteous and professional. He goes a great job explaining what he is doing and keeps us advised on his progress. If there are options he carefully explains them.

Todd and Mitch turned on the gas logs pilot light and let me film them explaining how to adjust the flame as well as turn the gas on and off and reset the pilot light. Very professional and helpful.
