"The technician did a great job when he came out to look at the unit. He fixed one and found a leak in the other one. I needed a quote for my home insurance company. Turns our Aire Serve Pro is in collaboration with the home warranty company to get as much of the repair as possible to not be covered by my home warranty. They would not give me a normal quote of time and materials. They would only give me a quote where all the costs are wrapped into a per pound of refrigerant cost. This drastically increases the cost per pound of refrigerant by 10x. You can literally buy 410a refrigerant for $10 per pound (see attached) but they wanted to charge $151 per pound with all the costs rolled in. The insurance company then says....we only pay the market rate of $10/pound for refrigerant and I have to pay the difference. Which means the insurance company only covers 10% of the repair. The woman said because I went thru insurance they had to do it this way and could give me a time/material quot"

Award winning. We take great pride in our experience, expertise, quality and customer service that we provide to meet our customers needs. It is our mission to provide a great experience from start to completion of a project.
"Multiple exterior repairs including: enhance the structure of a 2nd story porch, repair wood rot in several locations, storm door replacement, fence and post replacement and painting. Adam treats your house as if it's his own - he discovered additional wood rot and mouse entry points on the siding and re-fastened framing on the front door so it now operates like new. My house is now mouse free for the first time since it was purchased 28 years ago. Adam comes up with great solutions that I've never considered. There's no need to check his work with a level - it's always right on. He always does things the right way and gives you options to suit your budget. I'm a probably a difficult customer since I'm a retired engineer and Adam meets or exceeds all expections."
