HVAC reviews in Cincinnati, Ohio

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.

Sentry installed a 6 ton Water Furnace that replaced a 3 ton and a 4 ton heat pump system in our home . Their duct work craftsmanship is incredible and their work is top notch. Professional and courteous - a must use if considering a Geo thermal system.

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.

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.

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.

Sentry replaced our two heat pumps with a new geothermal system. Dave and his crew have shown themselves to be very knowledgeable and professional, but what really separates Sentry is how they communicate. Status updates and responses to questions and concerns are always clear and prompt. With Dave you always feel like you're working together to get the best solution. I'm recommending them at every opportunity.

I decided to give this small company a try, and I couldn’t believe how professional they were. Corey and Dave were extremely helpful from the initial estimate all the way through to the completed job. I highly recommend this company!

Wonderful people. Follow-through is on point would recommend to anybody.

On the busy side and not a lot of room. I decided to skip this place on initial contact. The good reviews are misleading.

Reasonable price professional service and do what they say they will do.

They were very helpful, and had everything I needed.

Great place for a/c repair parts. Friendly & helpful.

Great for most all trailer and truck needs. A large parts list and they work on refrigerator trucks.

Very Friendly and fast service, had to get APU fixed.

Cool place. Reefer oil change in less than hour. Break down right away
