HVAC reviews in Marietta, Georgia

Tyrell was very thourough and informative. He diagnosed and explained what he found and what he was doing to correct the problem He was very professional and friedly. I would highly recommend their company to anyone with HVAC proplems!

I would highly recommend Deason's Heating & Air. They were very professional and knowledgable. The problem I was experiencing was explained to me in details and they were able to address the issues. The gentlemen put protectors on their shoes and wore their masks. I would definitely use this company again.

Technician was professional and timely. Inspected system and provided detailed analysis of what the issues were and what he would do to repair them. I appreciated his honesty and felt the service was a great value for the money. I will use them again and tell me friends and neighbors about them as well.

I've been using Deason's for 30 years. Now that Mr. Deason is no longer involved with the business, there is a decided lack of forthright communication from the company. I was promised a Monday repair after a Friday diagnosis, which was completely understandable and acceptable. Monday came and went. A company rep told me Monday afternoon that it would be Tuesday or Wednesday, which turned into "maybe Thursday or Friday". I called a different company and was told that "yes, we can do that repair, but it takes a week to get the part". Okay, that also made sense and would be acceptable. I therefore surmised that Deason's had to order the part from the very beginning, and that it would take a week. I just wish they would've told me that from the beginning instead of a seeming run-around. The diagnosis, and then the eventual repair, was done quickly. No problem with that. PLEASE COMMUNICATE BETTER!

After doing some research me and my wife recently decided to have a Whole Home In-Duct Air Purifier system installed. The tech from Deason's arrived on time, and was very professional and their service was super affordable and was way less than what we anticipating. I would highly recommend this company.

Tyrell from Deason Heating & Air was pleasant, quick, on time, and knew what he was doing. Next time I have a problem or need AC maintenance I would gladly use Deason and request Tyrell. The cost was reasonable and I was not pushed or harnessed into buying a new unit.

On Sunday the 16th of August we had a small fire in our AC unit in the house. We were able to put it out, cut power to the unt and called Deason's with our issue. On Monday morning Tyrell was here to assess the situation and we needed to a whole new unit. Tyrell was able to provide us with a quote and what our options would be rather quickly. We scheduled our install for Wednesday. Tyrell and his team were here early Wednesday and installed our new AC unit. We are super pleased with the service and professionalism provided by them.

When my last HVAC system went I reached out to Reliable for a new system, and they provided a great quote. That is where the positives end.

After the initial installation in late 2019, the system immediately broke down and would not heat. The technicians that Reliable sent to inspect the error said the installation team did not install it correctly and broke the entire system. To remedy this they replaced the system and installed it again.

Fast forward to the following spring (2020) and the system breaks again as it was only blowing air and not cooling. Reliable claims they fixed the system as it is working, but to my surprise come the next year it breaks again... (spring 2021. It was determined that the issue was with the last repair and installation of how the draining pipe was routed. Finally, after this last service, they decide to charge me for the repair even though I am under the standard warranty of 5 years of labor. Then come 2022 and the system breaks yet again and they will refuse to serve as the warranty dispute is still ongoing.

This was a colossal mistake to work with Reliable, as their service, parts, system, customer service is a complete mess and the opposite of reliable. Their repairs team does not speak to installations, and their customer service is completely disconnected from any other departments rendering them useless. It's a wonder how anything gets done. I have now seen other reviews stating the same issues. If you have the opportunity to go with another provider go with them, it will be worth it even if it costs more upfront.

Zaroh, our technician, was very thorough in his explanation of what the service plan offered, and then did a great job performing maintenance and repairs on our two older units and maintenance on our recently installed new unit. I appreciated his patience and professionalism.

My Mom wouldn’t consider using anyone else!

Zaroh was knowledgeable, pleasant and very helpful in letting us understand the condition of the AC unit.

Travis Littles was easy to work with and explained everything carefully as we worked out the details for my purchase of a new heat pump.

Zaroh was extremely knowledgeable, professional and courteous.
He even explained to us how our HVAC works.
He was simply amazing.

Lucas Santos and his team were great! They arrived on time, were polite and careful through the whole process and cleaned up well after they were done! We are very happy with Moncrief and their process. We have an annual contract and will continue the service!
We were also very happy with Ken, the consultant! He explained everything very well and listened to our concerns about potential issues. Thank you to everyone!’

As always, great customer service and great technician!
