A One Heating, Air Conditioning and Plumbing LLC

Top Notch Service is the best way to describe this company.! Two weeks ago my AC went out and it couldn't be "MacGyvered". It was original to the house (1993) so it was time for a new heating and cooling system. I got estimates from 4 companies in the area. 2 estimates came from big companies with TV commercials, 1 from a medium size company whose truck I saw in my neighborhood and the last one from A One heating. A One Heating was recommended to me by my neighbor who had used them 5 years earlier to replace their system. I picked A One Heating for two reason. First the price was extremely fair. The other companies were charging between $3K-$5K more for the identical equipment, service and warranties. Second, I was totally impressed with Mr. Leery and his son Marlon. They didn't try to sell me stuff I didn't need, and they weren't pushy. They were honest in their assessment. And anytime I had a question Mr. Leery always answered the phone. The installation went without a hitch and Mr. Leery even contacted me a few days later to see if I had any questions with the new system or thermostat. Use A One Heating!! You will not be disapointed.

It was our first time to get the service of A One Heating and Air conditioning of Mr. Leerie. It was a great experience of their service because he was a hands-on owner and he is easy to reach when I had questions. He responds quickly to calls. He also has great workers in his team, Mr Everton and Mr. Earl. They were all very professional in dealing with clients. I would recommend his company to whoever asks me about air and heating services. Great job guys!

These guys are great. Came in and diagnosed my HVAC issues and gave me a great deal on a replacement unit. The financing company is great as well and the approval process was smooth! Glad to have cool air during this extraordinarily hot summer!

A One Heating a d Air Conditioning came into my home, and was very professional from beginning to end. They installed a new HVAC unit in as little as four days. The technicians worked very diligently in my home, making sure my family had as little down time as possible. I strongly recommend this company for all your HVAC repairs/replacement!!

Thank you A One Heating and Air Conditioning!!!

My AC wen out and gave them a call and they were extremely responsive during the buy season. They were quick and got out to us fast. They came out and took a look and were very professional and knowledgeable. Our unit has been giving us problems for years and we ended up purchasing a new unit from them. They gave us a great price on a new Trane model and have been very happy with it. I would highly recommend using them.

Professional, punctual, courteous, neat and reliable. Estimates were reasonable in keeping with industry standards. Work started and completed as scheduled. Leerie Simpson was patient with taking time to answer questions and helping to explore best options for deciding our HVAC cooling and heating needs. We can confidently recommend A One Heating Air Conditioning and plumbing LLC services without hesitation.

A One Heating and Plumbing was a lifesaver. We needed work done our AC system and A One was the right company to call. During the assessment appointment Mr Leerie and Son provided a detailed report of the entire heating and AC system quality and repairs needed. A One provided an itemized work order step by step installation; more importantly they did try and oversell.

The installation team of Earl and Everton, was on time and very courteous. Earl and Everton replace the unit in a timely manner and removed the old unit as well. I’m very pleased with the service and will be referring and using A One in the future. Great Business, Great team.

My AC went out, and A One came out the same day. They gave me a very fair estimate on a new unit and a good time schedule. I had a 15 year old unit that was over heating, and tripping the curcuit breaker. They arrived on time, and performed the installation very professionally. Everything is now running great. I would highly recommend this company.

A-One HVAC was a pleasure to deal with. Leerie and his son came out within a few hours of us calling about our hot water heater. They quickly explained the issue and gave us a quote on a replacement. The technician (Jamal) came out the next morning (Saturday) and replaced it. Outstanding customer service. Would definitely use this company again!

The whole A One team were a joy to work with. With the highest professionalism and efficiency, they came up with a plan, explained it to us in great detail and executed it swiftly, within our budget and were gone without a trace before we knew it and then they were nice enough to call a day later to make sure we were happy with our new Trane system. We are happy and warm in our home again! Highly recommended.
