Heating, Forced Air System Service - Installations (All Major Brands), AC
"Installation of a new furnace and air conditioner was done. We were so impressed with the professionalism and follow through of the CR Mechanical team. Rick contacted us promptly and advised us of our options and his recommendations for our project. We did some additional homework and decided to hire CR Mechanical. Craig arrived on schedule and installed the furnace and did some additional pipe work the first day. On the second day, the AC was installed on the new compressor was relocated to a new area that we had discussed. The job was completed as agreed with efficiency and neatness. I would recommend CR Mechanical with hesitation."

"I hired them to come out and do a tune up on my furnace. They were extremely professional, explained what they were doing and even took a camera to inspect all of the equipment, showing me every step of the way. Unfortunately I had some cracks in the original Furnace (16yr old), and it would be too much to repair. They scheduled someone the next morning to come out and price an entire new system with Furnace, AC (also original), and Ductwork cleaning. They were extremely thorough about our wants, needs, and various options. They wanted to make sure they got it right, and didn't just come in to say "this is how much it is. Yes or no" With the numerous guarantees (including 25% energy savings), and the quick work (from inspection to a whole new installation/duct cleaning in 3 days) this company was a pleasure to work with. Would highly recommend, and they are now our new HVAC company. I really appreciated their all in prices. They quoted everything (tax, permits, etc) and stated that no matter what, the price wouldn't increase. If they had to add or change things, that was the price. Was nice not to be quoted one price and get shocked with how much it REALLY was"
