Reliable HVAC Provider

Was looking for a new HVAC provider and have found a top notch partner in Hearthstone. Ended up having a major furnace failure right before Thanksgiving. This company was fantastic! Diana and Dave worked together so well to get my system diagnosed very quickly and efficiently. Paul and Ben delivered excellent work in replacing large complicated components quickly. Super knowledgeable and professional people in this company. They really care a lot about their customers. Thank You Hearthstone!

Fair Pricing & Fast Service

We have used Hearthstone for many years. Recently our 20+ year old furnace was on it's last legs and their staff responded quickly and installed a new furnace/heat pump combo at a fair price. They assisted us with financing and applying for energy saving rebates. We will always use Hearthstone for our heating/air conditioning needs. Many thanks to Dave and the gang!

Trouble-Free Installation

Replaced an existing Carrier HVAC system with a new Carrier Furnace and Heat Pump/Air Conditioning system recommended by Hearthstone's Dave Selke. He was very knowledgeable about assessing what would be best for my home and their prices were very competitive. I highly recommend Hearthstone for trouble free and economical installation experience.
