"The absolute best air conditioning/ heating service...prompt, reliable and honest. I worked in the a/c heating industry and have seen plenty of bad installations and over inflated pricing....I've seen people pay up to $7,000 or more for a new 2 ton system. I paid half that with A 1. And I got a top of the line quality system. Larry is very professional as well as his install team. I will be returning to A 1 for my second system later this year for the lower half of my home."

"I was impressed. I called expecting a delay. He came that evening. He solved the problem and had it running in an hour. I asked if he could do some cleaning to the condenser unit and he did even though it was already late in the evening. The charges were actually less than I expected!"

“Larry is my new best friend. He fixed the leak on my Air conditioner, recharged it. Fast, friendly and professional. Now I'm just "chillin"."

Karen K / Lawrenceville, Georgia

“I know the repairs that he recommended were accurate because the service company I normally use have been telling me this, so I appreciated his honesty. I also appreciate his honesty with the payment arrangement made.”

Larry was great. He came and assessed the problem and came back with his crew and had my air up and running in no time. I will continue to use them for all my servicing needs.

Johanna Carlton

Larry was great, honest and did not try to sell me anything that wasn't necessary. He did exactly what I needed as well as what he said he would without sugar coating anything. My upstairs heating/air unit was replaced today with a NEW RHEEM heat pump and air handler. Thank you Larry for the excellent service. Kudos to the installation team. When my downstairs unit needs to be replaced, Larry will be my go to person. Thank you so much.

I’m very pleased with the level of service I’ve received from A-1 starting with Larry working out all the details of the job to his professional installation team. Two thumbs up!

Donal Geldbach

I got three different quotes and A1 was by far the best. Great install of complete HVAC system, great financing options, always responsive. What's not to like?

Allen Hercules

Larry is the absolute best. He has taken very good to us from day one with our new home. He always responds to us in a timely manner and he is Mr. Fix It! He guarantees his work and always comes back out to get our heat pump system fixed without charging us another service fee. If you live in Gwinnett County be sure A-1 Heating & Air Conditioning is your first call for A/C and heating needs!

Halp Me

Larry from A-1 Heating & Air Conditioning was very prompt when our A/C unit stopped spinning. Larry quickly diagnosed the problem and completed the repair in less than a hour. I recommend A- 1 Heating & Air Conditioning.

Kenyetta Rivera

Had a problem with my air conditioner in the 2nd floor, wasn't cooling and contacted A-1 Heating & Air Conditioning late evening, left a voice mail.Larry Kitterman texted me right away,I gave him an idea of what was going on with the air conditioner via text message,he told me he would call me in the morning. Right enough he called me in the morning and we set a suitable time right away and he was there on time. got the Air Conditioner running in less than 20 mins. I've dealt with other companies(not easy), this company is nothing like that. They are very professional and friendly.Above all they know the job...I would highly recommend them

Larry and his crew are always courteous and timely. He has been our air and heating man for the past 16 years and we love the work he does. He always answers his phone and never leaves us waiting,

Bonnie Boudreau

Larry, from A-1 heating not only provided great service with repairing my HVAC system but ensured that I received an honest price. On the second encounter (within a week), I asked Larry to provide a post home inspection response to several question. Larry visited my home and provided a courtesy HVAC assessment. I would/will recommend Larry to all of my friends and family for future HVAC system issues. Lisa

Lisa Williams

I appreciated the fair and honest approach in the pricing. The installation was excellent and extremely fast with attention to little details that matter a lot to me. When a company does this well on my project then I have to share the experience. Thanks Larry and David. I'm recommending my family in Gwinnett call you when they need a new HVAC system.

V Owens

Service was prompt. Everything was completed exactly as promised for the price agreed upon.

A Robb

Larry and his crew delivered excellent customer service in our time of need. Our Rheem HVAC system was in need of replacement after 25 years of use. When the AC finally quit, I called Larry and he came to our house within an hour. He recommended the correct system for our needs, established a firm price and scheduled the installation. He and his crew met all of my expectations. I cannot imagine someone with more expertise or a company with more integrity than A-1 Heating & Air Conditioning.

Gerald Solamon

Excellent work, got in and got out and did an excellent job! Will not hesitate to use them again if the need arises!

Apex Strategic Partners

Larry is very knowledgeable and nice. He has been fixing the air and heat in the past 3 homes I have owned. He is always quick to return calls and comes to repair or replace unit within a day or two. I highly recommend him and his staff.

Lisa Gravlee

Great service indeed. The service techs were timely, nice, and thurough. They came out hooked up the brand new unit and made sure it worked. I’ve never made this type of purchase although I’ve talked with different companies and had a lot of estimates. Their prices are fair and from my old unit to the new one. NIGHT and DAY!! The unit recommended was rheem the same company that made my filters. Warranties are great. Really knowledgeable staff and friendly. Their very timely with responses and open to answer any questions I had about the purchase or unit.

Tim Barnes

Kade Hill

Great job.

Kwame Ohemeng

The absolute best air conditioning/ heating service in the Atlanta suburbs..prompt, reliable and honest. I was a designer in the home renovation industry and have seen plenty of bad disaster installations and over inflated pricing. I've seen people pay up to $7,000 or more for a new 2 ton system. All systems are just basically a fan, coils and coolant. Don't let anyone tell you anything else! Bells and whistles won't make up for a bad install. It is the installer and installation that is most important. Bad installs are extremely common. Most companies send out barely trained techs. And if they send out a sales reps you are really in for a high priced system as their job is to get as much commission off of you as they can. Larry is an expert with extremely competent installers. I paid half that with A 1. And I got a top of the line quality system.Larry is very professional as well as his install team. I will be returning to A 1 for my second system later this year for the lower half of my home. Second post a year later: I did buy my second system from Larry. Again, got the best install at the best price. My new A.C. systems, both of them from Larry, have been great and my utility bills are one-third less. Any question I have all I have to do is call Larry. He is most responsive and professional. I wouldn't consider going elsewhere and paying over inflated pricing and bad installs. Larry is the best. Third post a year later: two days before Xmas and system won't go on. I call Larry and he comes over the same day. Minor issue resolved quickly by Larry. Wow! Now that's service! Larry stands by his customers. He cares.
