David M.
Great experience with Sentry. They made it clear from the outset they really wanted my business and went above and beyond to earn it. Ben who was our salesman was outstanding! He was knowledgeable, responsive and made sure the installation was flawless. The installation team also did a tremendous job. They worked hard, were a pleasure to have in our home and left everything totally cleaned up. I would unreservedly recommend Sentry, Ben and this team if you are looking for HVAC service or equipment.

I couldn't be more pleased with the service I received from Sentry Heating & AC. Today, Jamie and his apprentice, Chase, took on a very challenging HVAC installation on a day when temperatures were nearly 100 degrees. They spent hours working both outside and under the house, yet they remained professional, courteous, and positive throughout the entire job. What impressed me most was the care they took with my home and landscaping. They were respectful of my property, worked tirelessly all day, and even stayed after hours to make sure everything was installed correctly and operating perfectly before they left. This isn't my first experience with Sentry, and once again they exceeded my expectations. They consistently provide excellent products and outstanding customer service. Jamie and Chase are a tremendous asset to the company, and I highly recommend Sentry to anyone looking for quality HVAC service.

Our experience with Sentry Heating was excellent – 5 stars for sure! From the start David and Seth fixed the old system and recommended replacement. Ben McCoy provided information on system options, installation and financing. Jamie and James arrived the following week to install a new HVAC system. The techs did a thorough, professional, and conscientious job. With the new unit we are enjoying comfortable living especially during this hot summer. Thanks to all who helped coordinate the installation!

When both of our air conditioners stopped cooling, we looked for the name/number of an A/C repairman and happened to have kept a card from Sentry from several years prior when they were working in the neighborhood. We looked up the company, read the reviews, and decided to take a chance. They came out, checked our system, and let us know what was wrong. Due to the age of our A/C units and what it would cost to fix them, we decided it was time to replace. The process was easy and we were given multiple choices from which to choose. While the installation went smoothly, over the course of a couple of days, we did encounter issues with the way the drainage pipes coming from the A/C unit had initially been installed years prior. Jamie, James, Tristan, and Ben are the nicest, most polite, and conscientious employees. We can't say enough about Jamie and James who spent several days with us until they were able to locate the problem with the pipes. Once they did, they had the issue corrected within a couple of hours and everything has been working great! While it is expensive to replace an A/C unit, the peace of mind from knowing a company will provide great service is invaluable.

Jake with Sentry helped my daughter rescue a baby bluebird from inside our HVAC system. He even brought a box to put the bird in and was ready to take him to a wildlife center. My daughter took the bird to a rescue center but the fact that Jake was willing to do that for us is exceptional customer service!

Hannia and Luis provided great service during my spring maintenance. So much so they identified one part that needed repair and came back after hours to assure completion. Great to see two team members put customers first. Well Done!
