I am very happy with my purchase and the fireplace installation. My wife and I have used it multiple times since it was installed and it works exactly as advertised. It turned a cold room in to a... comfy room that we thoroughly enjoy.My wife and I were leaning towards purchasing a fireplace with high BTU output and a fan. The team at Harding pushed back, and said we would be too hot. I appreciate their honesty. Consider they gave up a bigger sale.The installers (James + Adam) were thorough, neat and patient answering our many questions. I told them that my former wood fireplace had an ice-cold hearth. I asked them why, and they showed me that the original fireplace was not assembled correctly; it allowed cold air to come down around the fireplace, especially the hearth. It was awful. I really appreciated how they sealed the leak and added insulation. The problem was eliminated.The finishing team (Brandon and colleague) were also meticulous. They did not rush the job. I was out of town during the finishing and they suggested WhatsApp video calls, which worked very well and allayed my concerns.I would especially like to acknowledge Kirsten Neumarker. She is the project coordinator at Harding who schedules resources to install and finish fireplaces. She is very organized and is an excellent communicator. She reached out to me proactively and worked hard to accommodate my schedule also. She would often answer my emails and phone calls in minutes. I find this uncommon among contractors. She made a difference.Overall, a positive experience and I recommend them without reservations.Oh, and check out the photo attached of the finished product. We love it!Mikeread more

Also a report has been filed towards this issue and I believe communication will be taken to improve future services. I really like this manner! Thank you.//I have no heat on the coldest day this winter. I called for service at 10:28am, and the office lady said someone will reach me ASAP. I called at 17:26pm again because NO ONE called me the whole day. And I was told there is a long list so THEY DON'T CARE! I HAVE TO WAIT! And this is a same problem happened second time in two years.

I had them install a Sterling Model GG 45,000 BTU Natural Gas Garage Heater with a Nest Learning Thermostat in my... double garage (Man-Cave).The sales rep, Brian was professional, friendly, he wasn’t pushy at all and he came under budget. Kirsten constantly kept me up to date on the installer’s scheduling and was a true professional.

Harding Heating & Air Conditioning were excellent. We had an issue with our furnace fan and I spoke to Natasha Wright (Service Coordinator) who first tried to troubleshoot the problem with me to... save costs, etc. Once that didn't work, a technician, Marc Gagon, attended. He quickly diagnosed the problem (faulty control board), but didn't stop there. He investigated the source - water under the AC coils. Further, he went outside to ensure the A/C unit was working properly. Marc Gagon is very professional, competent and took the time to explain things. He is a asset to Harding Heating & Air Conditioning, along with Natasha Wright. I highly recommend this company for your heating and a/c needs. Shawnread more
