Services
Repairs
Report
When a homeowner experiences a breakdown of their HVAC system, it's often because they failed to conduct regular maintenance checks. The repairman shows up and asks the homeowner when the last time he or she performed a particular check to the system, and the answer is often never or not for many years.
Maintenance
Report
The best way to keep your HVAC system running smoothly is to take advantage of maintenance agreements set forth by your cooling and heating contractor. Homeowners who use maintenance agreements will see less emergency repair needs and less problems with their overall HVAC system. When you purchase a heating or cooling unit, make sure you ask about our Sentry Security Service agreements.
Geothermal
Report
Geothermal is a HVAC system that uses the energy produced and stored by the earth to heat and cool your home. In simple terms, it works similar to your common household refrigerator. The refrigerator produces both cold (for the inside) and heat (out the back side) on a constant basis by compressing Freon.

We have been working to improve energy efficiency and reduce our carbon footprint, so we were excited to hear about the renewed federal tax credit for geothermal heat pump systems. After researching the technology and contacting several companies for quotes, we selected Sentry Heating & Air. Their price was very competitive, and I especially appreciated that Dave was willing to work with me to determine my needs, rather than to just prescribe the "only" solution.

I will admit that I was a bit nervous about going with such a small company rather than a bigger name, but I needn't have been. Dave and Corey know their craft, and I really admired watching their teamwork as they brought the system to life. There were a couple small snafus (like the delivery date for the main unit), but Dave was extremely responsive and responsible, and everything was completed in the timeframe desired.

The system has been working wonderfully through this hot summer, I am totally spoiled by the comfort of the new zone system, and our electric bills have been amazingly low. I would not hesitate to contact Sentry Heating & Air for further work.

I had geothermal put in 6 years ago by Sentry. I just want to express my gratitude and appreciation to Dave and Cory for a great job and their service throughout those years. They're always prompt and professional. The whole system still works terrific. It's quiet, efficient and distributes air lightly and evenly. No cold spots in the winter. Auxiliary heat doesn't even kick in yet at 0°F. During the summer, a/c can actually get too chilly to where I have to turn up the thermostat. Two households next to me also use Sentry.

Corey and Dave were extremely prompt and professional with every aspect of the job. I am an engineer by profession and was kept highly involved with all aspects of the installation. The sub contractor that installed the ground loops were also extremely professional and work diligently in some less than optimal winter conditions.

I wanted to say that having Sentry put in my geothermal system has been one of the best decisions I've made. I use to have a heat pump with a propane backup. We used on an average of 800+ gallons of propane a year. Since we've put our geothermal system in, we now use 0 propane. This is remarkable considering a couple years ago how cold it was. I cannot be more happy with Dave and his crew.

We've had zero problems with it and this is our 4th year with it. If you are considering a geothermal for your house and you have reservations, Stop now and call Sentry. You'll be happy with the results. Terry and Betty Armacost.

Dave has worked with me for the last 8 years since he installed a geothermal system in our home. Dave has always been on time, thorough on doing the job right and leaves the worksite clean. He has gone above and beyond many times. I strongly endorse Dave and his company Sentry Heating and Air.

Happy to make Corey and David my first Angie's List review. I signed up here today to look up reviews on window installers and thought I would look them up. We had David and Corey install our ground-source HP last fall. We obtained estimates from three different contractors and felt the best about Sentry.

When we added a new room onto the back of our house a few years ago, my husband (a retired science teacher) was very impressed with the information he had seen and heard about Geothermal heating and cooling systems. Needless to say that is what we chose to go to not only with the new addition but with the whole house. Dave Bowman is very professional and really know his stuff.

He is thorough with the recommended six month check ups and the price is quite reasonable. We have had a lowering of our heating and cooling costs since putting in the system. I would highly recommend Sentry Geothermal system to anyone considering making a change to the current system they have in their homes.

Expert installation under difficult and demanding conditions to integrate with pre-existing heating systems. Absolutely a pleasure to work with true experts. Flawless installation and perfect performance in two separate installations.

My house had poor air distribution in certain areas such that in the summer some rooms did not get enough cool air and were very hot. Chris and Dave made multiple visits to the house to assess different options for improving the air circulation. They determined the best option was to set up a zoned system. They installed a high efficiency furnace and high efficiency air conditioner and the zone controller and dampers. Their crew was very attentive to details, worked diligently, and cleaned up the work area. Now, I need to wait for hot weather to see how well the zones work.

Installed geothermal heating and A/C system, and redesigned duct work to accommodate. Dave and his crew are very knowledgeable and professional. Communications were significantly better than any contractor I've ever worked with - never failed to let me know what was happening. Responded and continues to respond quickly to questions and requests. Followed through and finished every task.

Retrofitted my old house with Geothermal - since the house did not previous duct work, there is a lot of labor involved. But I don't mind, everyone who has been in my home has been so incredibly nice and patient with me and my dogs. Dave, Vincent and Corey have been fantastic throughout this project.
