"Good morning,
I wanted to take some time to brag on your employees. This past weekend, my AC stopped working early Saturday morning, and being a new homeowner, I was pretty much clueless on what to do next. So, I woke up early Saturday to make calls. I saw your company’s number on the AC unit outside and called immediately. When Sherry returned my call, she was so gracious and kind. She told me what the next steps would be, and even conferenced in an on call technician (Berry) to help talk me through turning the system off so things could defrost. Being that it was the weekend, I knew staffing was limited. So, the fact that they took the time to slowly walk me through everything meant the world to me. Fast-forward to Saturday afternoon, Julian arrived at our house. He was an absolute delight. He explained what happened, and how he resolved the problem. From start to finish, my experience with your team was amazing! Every single person I talked to made me feel valued and heard. I appreciate customer service like this. Because of my excellent experience, I didn’t hesitate to sign up for your maintenance program.
I look forward to working with your team in the future, and I am thankful I will have Reliance keeping a close eye on my home’s HVAC system from now on.
Please let Sherry, Berry & Julian know their hard work is valued, appreciated and paying off! I am a confident customer enjoying a very cool house this week...all thanks to them. :)"

– Sincerely, Kate Conerly Ball

" Thank you for sending your A-Team to install my new central heat/air unit on Saturday, June 27, 2020. They were extremely kind, considerate and respectful as they installed my new system. They were also very competent with the installation process which was not an easy procedure. They put in the extra effort to see that the work was done right taking pride in what they did. Nick even went the extra mile to make sure the filter was enclosed so that the weather would not have the opportunity to negatively impact it, such as keeping the filter damp, which was happening with the old system. You have a winning team with these guys - Nick, Adam, John and Colby!! They even made sure they cleaned up their work area before leaving. Everyone I dealt with at Reliance Heating and Air, including yourself, was very nice, kind and professional!!
My only concern was installing a Lennox brand (3 1/2 ton) unit instead of a Carrier or Trane system I have concerns about Lennox quality, but I trust your recommendation of a Lennox heat pump system to replace my old Ruud heat pump unit. Time will certainly tell the story!! Thank you again for getting the job scheduled quickly and for sending this awesome team to do the job!!

Your A-Team, 2) Left side with air filter door constructed by Nick, 3) Right side of back cover.
Numbers 2 and 3 are examples of that extra mile!! I will definitely recommend Reliance Heating and Air to friends!!!!

"Our air conditioning was having problems and Reliance came out. They were patient and tried to fix it 2 times by changing filters, recommending an electrician and then finally cleaning the coils and changing the filters. Of course, after all that, it was still not working well. They came out to replace it with a new system. All their employees were professional, knowledgeable and not pushy. They tried saving me money. I did not mind paying them to replace it. And Now I'm needing to call them for my upstairs.!! When it rains it pours... I'm sure I will get just as good service."

"As homeowners, we have used Reliance H&A for 20 years now. They have always provided prompt high quality service, with friendly service staff. Not only have they serviced our existing systems, but also installed a complete new system when we remodeled our home. You can't get any better than these folks!"

– Mark K.

"Once upon a time, I was a homebuilder. After several tries, I selected Reliance to do my new homes installations. Since then (14 years), I've had an annual service contract for Spring and Fall checkups and tune ups. They've replaced my crappy original system (not my install) with a new high efficiency system in 2005, and maintained it scrupulously ever since. In May, the compressor (outside unit) wouldn't start. Their serviceman came right out, inspected it, replaced a kaput electrical condenser, rechecked all the functions and pressures, collected $119 from me, and went his merry way, all in the space of an hour. There are horror stories out posted all over consumer sites about crooked HVAC contractors. It's easy to be fooled by crooks because what typical homeowner knows anything about the innards of their AIR CONDITIONER? My status as an annual service customer saved me a trip charge ($75), and it's good to be cool in the Summertime!"

"I have used Reliance Heating and Air Conditioning in Conyers for 20 years for my HVAC. I am located in Alpharetta. They service all of metro Atlanta. My elderly Mother's air conditioner went out last week. Reliance was out quickly when I told them the homeowner was 83 years old. After discovering the compressor had gone, I informed their technician, Robbie that my mother is on a very limited income. He went to work trying to find her a reasonably priced replacement. He spent a lot of time on this and was genuinely concerned about her. The owner had him replace the air conditioner unit and I am sure they didn't end up making a dime on this service. There are few companies that actually care and I and my mother are forever grateful to them. This is an honest and hardworking bunch of people. I will use them for my service work forever. Give them a try. I know you will be pleased."

"My air conditioner went out. The fan on the compressor was not working. A switch was all that was needed. It was repaired quickly. The service rep was really helpful."

– Our Customer

"We were having problems cooling our home so we contacted Reliance. They came and discovered that the unit we had was too small for our home. Once our new unit was installed they called several weeks later to make sure that everything was going okay. They have fabulous customer service and are very prompt on getting you scheduled quickly and at a time that is convenient for you. We love Reliance and will continue to use them in the future."

– Our Customer

"My upstairs air conditioner went out. I thought I was going to need to spend a few thousand dollars to replace. Jeff from Reliance showed up, did a complete analysis of my system and determined that I only needed a part replaced. Total cost was pennies compared to my original estimate. Thank you Reliance, I will call you again."
