Report
They are great. Our furnace would not run and needed work, but we asked if they could do a new install for us. They fit us in that night and worked after hours to get it done. No issues so far and everything is working great. We are so grateful and could not recommend them more.

I am a first time customer. Day one was to service my oil-fired furnace. During the servicing Mike found an issue that could be a problem during the winter. The next day they submitted a quote, found the items needed to correct issue, came back to my house and fixed the problem. WOW!

Mixed experience. Outstanding on split duct installation. Oil burner maintenance, sometimes goes well, other times not so good (maintenance service broke its previously fine operation). Could use service, again, and but find I'm now apprehensive.

Report
I contacted three HVAC companies for a replacement of my existing heat pump system. Company A: supplied a quote on the spot and I next received a follow up that I should order now because of price increases in August. Company B: quote received within one day - discount if I signed before end of month. My experience with Kevin at Absolute Mechanical (family owned business) was excellent. Kevin came out examined the existing installation, we discussed several options regarding equipment capacity, warranties, and cost of ownership. I graded all three bids using the following criteria: Quality of Equipment

I highly recommend this company for your HVAC needs/ services. We have used them twice for our home AC repair and both times they diagnosed and repaired it effectively and cost efficient. A GREAT Company with professional employees who know their field! 👍. Thank you Mike and Kevin!!

These guys have helped me out several times on short notice. Fair prices and knowledgeable technicians. Most recently my hot water was out. I called and the same day they got a technician out and he fixed the problem. My furnace starter motor had died. They were shorthanded, but went above and beyond to get to me, even though they were booked for the day. I appreciate that kind of effort very much.

Mike responded on the coldest day of the year, on an early Sunday morning, when our furnace would not fire. Mike was cheerful and helpful and had our furnace up and running within an hour. Thanks, Mike.
