Very pleasant and focused. I was unable to go into the basement so my husband checked in with them and he had no problems. The installation team arrived around 9am and left about 3pm. They placed cloths down to walk on as they needed to make multiple trips bringing in tools and the new furnace. And again "moving everything out" . Our old furnace died after 35 years of hard work. Didn't need the AC replaced at this time. They cleaned the cooling coils so I'm eager to see if the AC works better come summer. We got the furnace done under the all electric deadline. Very pleased with the service. And the constant notifications of who was coming, when they would arrive, and phone calls in case I didn't see their texts. Never left in the dark.

Very respectful. Offered solutions for now and moving forward. Was not pushing any product, which I appreciate. Fixed the problem quickly and was helpful. I will also add that I have used their services for my AC and hot water heater. They have the best receptionist and their timelines has been great. I know exactly when someone is gonna be here.

Buyer Beware. Get a second quote.
Fortunately we did. That is when I discovered this company had tripled the cost of the part we needed to fix our furnace.
When Phil the owner first came out, he was here for over an hour and ended his inspection with thinking our problem was the pressure switch. He called his company for 'back up' and Dylan came out to also inspect, stating "Pressure switches never go bad." He used a camera to correctly diagnose the issue - rusted air flow component in the heater exchange lessening adequate air supply.
At this time we were in the cold for 1.5 days, it took another day to get an estimate for a new heater exchange, (with labor), at $3,882.00!
I called a family friend to run everything by him since he would know if this seemed correct; he laughed and said we were being taken for a ride. He then called a wholesaler and asked for the exact part and was quoted $1,130.00. (this is no labor)
I called the company to ask why they would triple the part; I was informed, by the wife, their overhead is more expensive than smaller companies and they pad costs to cover it.
(Literally. This is verbatim.)
I am giving 2 stars because they did correctly diagnose the issue.
At the end of the first visit they ended up not charging us for the pressure switch we did not need but only charged $22.00 for the inspection. I feel this is a tactic to win trust with their customers in order to reel unsuspecting people into an estimate that would more than pay for the first visit. I am very grateful we were not taken advantage of; I hope you wont be either.
