Jamie B.
After researching and getting multiple price estimates for a Generac
whole-house standby generator, I was most impressed with everything Sentry had to offer.
Starting with Ben McCoy, who came to my home to do an on site estimate. He was super nice and professional. I told him what I wanted to do and gave him an idea of what I wanted to spend. He exceeded my expectations by putting together a proposal that was far less in price than others I had called on, for a 24kw generator that suited my home’s needs. He was honest, no bull*. Didn’t try to push me into warranty upgrades, or sell me a product I wasn’t interested in. Thanks Ben! Job well done!
The install team, some of the best home service industry workers I’ve had at my home.
On time. Friendly. Knowledgeable. Efficient, and professional.
Easy to work with, all good senses of humor, and just nice guys. Diego and his team, are real assets to Sentry Heating and Air and I hope Sentry knows that! I’m sure they do.
Diego, Jamie, Kevin, James, Zac, thank you for making a major purchase and installation a stress free event for me! Thank you! You’re all welcome at my home for biscuits and gravy, coffee and donuts anytime!
I do recommend Sentry Heating & Air. Family owned, established and proven. Give them a call. You won’t be let down, I promise.

Our 23 year old main level HVAC unit developed a freon leak and was determined to be unrepairable. The technician that performed the system check was knowledgeable and very personable – also a very effective communicator. The sales team responded later the same day and came to my home to determine the HVAC requirements that the replacement HVAC unit would have to meet. Again, the sales person was was knowledgeable and very personable – also a very effective communicator. By the end of the day I had a system replacement work order in place and an appointment for the install the following work day. The install team was prompt, polite, proficient and knew their stuff. By mid afternoon I had the replacement system up and running. In summary, Sentry is a first class customer service oriented company. Based on my most recent experience I would highly recommend them to others.

We had a leak at the second water meter at our home and shut off water to the house. Sentry was able to immediately dispatch Devonn Wead and he arrived even before I finished cutting away obstructing bushes. Devonn identified the problem and also showed me how to shut off the water supply to the second meter which serves our irrigation system. He was terrific. Amazing service on short notice. Sentry installed and maintains our whole-house backup generator and handles HVAC maintenance as well. Highly recommend their services.
