Our AC was not cooling our home on these very hot days. It worked but it wasn't keeping up. We were sure we would have to buy a new AC but Paul came out and totally fixed everything perfectly. He was very professional, kind and knowledgeable. Will definitely request Paul if we ever need help with our AC or heat. It works perfectly now!

Hearthstone installed my new furnace yesterday. I was extremely pleased with the entire process. Each person on their team was very knowledgeable and professional. They all took the extra time to make me aware of all my options and to make sure I understood and to guide me through these options before finalizing. The firm's president came to my house and spent nearly 2 hours to fully assess my needs to in order to recommend the best system for me. I trust them completely and would definitely recommend them.

Zak came to my home yesterday, and he saved the day! My AC was not working properly. He was quickly able to diagnose and correct the issue all for a reasonable price. Even more impressive, I called to schedule and appointment, and Zak arrived within two hours of my initial call. I will definitely be using Hearthstone again!

Paul was fantastic. I called at 7:00am when we woke up to a 59 degree house on a very cold day. By 8:00am Paul was here. Had the problem diagnosed by 8:05 and by 8:35 the motor in my furnace was replaced and heat was on! Fair prices, personable service and extremely fast without any "emergency fees" or anything like that. Would recommend and will be using Hearthstone again if the need ever arises.

Hearthstone HVAC is the best. At 3 a.m. this morning I woke up to a cold house. After 15 minutes of troubleshooting, I left a message on their answering service. I was called back in 5 minutes and a repair man was at my house by 5 a.m. Turns out loose garbage had wrapped itself around my furnace exhaust pipes and that is why the furnace would not start. They are reliable, courteous & honest. I would definitely recommend them to friends and colleagues.

I was more than impressed with Hearthstone. I called at 7:45 the day after Christmas, in the midst of a polar vortex. They had a repairman to my property within 30 minutes. Furnace was repaired in an hour and the service man, Zack, was incredibly nice and professional.
