Woke up this morning with no heat in the house. Within a couple of hours a Harding service technician was at the door and was able to replace the blower unit in less than 20 minute restoring heat to my home. Just want to state that the service was great and the staff were professional and friendly.I'm glad I've been with Harding for the past 8 years,'s to many more.Great job!

Harding Heating and Air Conditioning installed our Furnace and Air Conditioning when we purchased or new home in 2011. We have enjoyed excellent service from them for the last 9 years. We would not hesitate in using their company again in the future.

Very happy with the installation and the amount of time it took. They arrived on time and were very patient as well as thorough in explaining how the work would be done. Afterwards, they walked me through the entire system and how to use my new thermostat. They left my home neat and tidy. Thank you Team Harding!

We have been using Harding for several years. They are hands-down the best heating and air conditioning company we have ever used! The administrative staff is always friendly and helpful and the technicians who have done the service for us are fantastic! The customer service here is great and it feels a lot more personable than the big guys like reliance. I have recommended to many of my family and friends.

We’ve used Harding for 6+ years and they always exceed our expectations. Friendly staff, knowledgeable technicians and reasonable prices. We couldn’t ask for better. They installed the ac unit at our first house and anytime we needed them the service calls were great. We bought a new house July 2019. It wasn’t long after that we were told we needed a new furnace and ac. We went withHarding...obviously.

I recently had an air conditioning unit installed in our home and had a great experience working with Harding. Every member of the team (sales, install department, etc.) was professional, and very helpful. Our unit was installed during the pandemic and the team was very respectful of social distancing boundaries and kept the work area as clean as possible to minimize risk to anyone. Overall, the team was a pleasure to work with and did a quality job. They exceeded our expectations – I highly recommend Harding Heating & Air Conditioning!

Even though we had an on-going issue with our Amana Distinctions AC that was originally installed in June 2012, Harding's team stood behind their product and went out of their way to extend service without any question about warranty. It was a pleasure to deal with their inside staff as well as two installers that are top-notch. Thanks Steve, Brendan and Megan for superlative service!

We have a 28 year old air-source heat pump that needed some TLC.Harding sent their tech out to diagnose, and provide options and pricing. Very reasonable.Exterior unit needed a new fan motor. Within a few days an installer came and installed new motor, but made a slight error, and it was rotating the wrong way. Quick call had it corrected. Further found our defrost board was faulty. Harding provided quote upfront for a replacement aftermarket board. Kept in contact as to timeline and expected deliver and installation date.Tech came on-site as promised, did the install, and stayed to make sure unit was cycling properly. Billed for the quoted amount.Harding delivers what's promised, when promised, at quoted price. And has staff who know what they're looking at.Hard to ask for more from an HVAC service provider.

Reached the emergency hotline for a furnace issue. Understandably they were very busy on a snowy evening but Eli managed to drop by just before midnight to get it working!

Very professional amazing staff. We had a technician come to see our old air conditioner which was beyond repair (we figured it would be). Next they had a staff member come to our house to look at our furnaces and give recommendations for new air conditioners, he was very thorough and explained all our options in detail. Finally they came to disconnect the old air conditioner to take away for us and install the new air conditioners. The technicians were on time, very polite, did an amazing job and cleaned up after themselves above and beyond what I expected. Their prices were very reasonable and the after care packages that are included give us peace of mind for the future. I would highly recommend this company to anyone. Thank you Harding!
