I have used Sentry for HVAC maintenance for 10 years with good results, so when one of my units needed to be replaced, I chose Sentry to install a new Carrier unit. I was most impressed. The install team arrived at my home at 7:30 a.m. and worked until 5:30 p.m. Joseph, Jamie and Alex were very professional. They were careful to wear shoe coverings when inside and cleaned up before they left. It was raining, so they put up a tent for the outside work.

They were so quiet, I hardly knew they were in my home. They went over everything they did with me before they left. It was a great experience. As anticipated, my upstairs unit needed to be replaced 3 months after Sentry did a great job replacing the downstairs unit. This time it was Sentry team Ben (sales), Jamie (installer from March install) and Jordan T (installer) to the rescue. Jamie and JT did an outstanding job in extreme attic heat. As before, they were polite and professional. Great experience. I hope to be cool in the summer and warm in the winter for many years to come. Thank you, Sentry.

My main level HVAC gave out in the middle of June! My mother lives with us and has COPD, so the added heat and humidity were an added pressure on her breathing. Since Sentry had installed our second level HVAC several years ago, I knew I could call them and get excellent service. They came the next day and started work the following day. Kenneth Wells explained that I could add an air purifier that would help my mom's breathing on a daily basis.

Great News! Thanks Kenneth. The two technicians, Jamie and Jordan H.,W ere both very friendly and professional. They worked really hard to get the job done before the end of day. They were life savers! I will definitely recommend Sentry services to others, as well as continue to use myself!

I recently had my ductwork replaced. Everyone that I dealt with at Sentry was very knowledgeable, professional, and courteous. Everyone starting with the technician, Cole, who evaluated the problem, to Ben, who planned the replacement, to Terry and his crews that did the installation were great. They kept me updated and informed every step of the way. I will recommend Sentry to everyone!

Been using Sentry for 15 years and very pleased with their service. Recently had new air units installed, Jamie and JT were the installers. Absolutely two of the hardest working installers I've seen. They were polite, friendly, knowledgeable, and accommodating to any question or concerns I had. I never felt uncomfortable asking either of them a question, very customer conscience. They also were careful not to damage our home, took necessary precautions to protect our carpets and such. Really nice guys, welcome in our home any time.

Our experience with Sentry Heating was excellent. From the start Tom diagnosed our system and recommended replacement. Ben McCoy provided information on system options, installation and financing. Jamie, Alex, and Dontae arrived the next day to install a new upstairs HVAC Ecobee Carrier system. The techs did a thorough, professional job and we are enjoying cool air again. Many thanks to all who coordinated this install. We highly recommend this company.
