Best service in the entire Atlanta area. Polite, friendly and professional all the way. Despite a heavy schedule in 95 degree July weather, Harding was able to squeeze me in in the afternoon. Courteous and knowledgeable tech arrived at 3pm and had my AC unit up and running in a half hour. Be sure to call these folks first: you won't need to call anyone else. Kudos, Harding!




Once again Harding Plumbing to the rescue. Frozen split pipe in a horrible, hard to reach location. Sent Zach - polite, professional and knowledgeable. Great job and reasonable. We have also used Harding for HVAC and believe it or not our septic and always performed a great job at a reasonable price. Thanks Harding Plumbing.

I called in the morning. The appointment setter was very polite and scheduled me right away. I was so lucky that they could come right out. The service tech was at my home by early afternoon. He was very courteous and professional. Took care of my problem and was on his way in an hour.

When I first called them they were extremely nice and polite. The 2 men who came to my house THE SAME DAY I CALLED were polite and explained everything! I would recommend them to anyone!

Recently did repair at my home. Did a fine job. Price was reasonable too.

On Monday afternoon at 5:55, our compressor went out. Normally we have to replace the hard-start capacitor once or twice a year (it is 17 years old and eats them like candy). I called around and everybody was closed, but Harding Plumbing Heating and Cooling answered their phone. Even though they closed at 5:00, one of the owners (Jack) stayed until 6:30 to sell me the part. That's dedication!

When the new part didn't fix things, it was time for a new compressor. I explored my options with several companies. Because of its age, it didn't make sense to just fix the compressor. I decided to go with a whole new unit, both inside and out. Robert sized everything on Tuesday (along with competing HVAC companies). I did my research and Harding has an A+ BBB rating, and they were hundreds less than the other guys.

Wednesday morning I called Robert, told him they had the job, and on Thursday they were installing the hardware. Total time was about 3 1/2 hours. Their technicians were courteous and nice. The techs made sure they didn't mar the hardwood floors. All the old stuff was hauled away. They even offered to sweep the hallway beneath the attic stairs!

I have never written an on-line review of a company, but I felt compelled to do so this time because of the exceptional service and price I received from Harding. The parts and labor guarantee was the best I saw. I will do business again with the guys at Harding Plumbing Heating and Cooling without hesitation.

We lost our a/c during the hottest part of summer. What we thought would be an easy fix turned out be a new system. The Harding A/C Tech helped us make an affordable decision and they fit us in quickly, knowing we had no a/c with temperatures at almost 100 degrees. The installation was fast and we were nice and cool when there were heat warnings. We will use Harding Plumbing, Heating and Cooling from now on!!! The employess, everyone we dealt with, were GREAT!!!!!!!!!



Outstanding and Excellent

Would rate this company 10 stars if I could ! Excellent company to do business with. Reasonable rates, excellent service, and very friendly and knowledgable technicians. Will definantly recommend this company to others for all of their plumbing and air conditioning needs. Owner Gary Still very fast response to my a/c questions and needs.The technician, Allen, represents this company VERY well.



Excellent service

Excellent service both times we called them for air conditioning repair. Responded quickly. Knowledgeable technicians. Reasonable fees.
