The installers did a great job

“The installers did a great job. The only downside is that the unit is noiser than the older one. I would have prefer a less noise.” – Francisco M.

I would recommend them when you either need service or new equipment

“I have been a Doornbos customer for many many years and when my air went out in June they were the only company I called due to past experiences. They replaced my furnace along with the air since it went out. They are very professional, always do great work and everyone is friendly and accommodating. I would recommend them when you either need service or new equipment.”

– Donna W.


I highly recommend Doornbos and Technician Dan Lavarda

“On 7-22-20, I had 2 AC units serviced by Mr. Dan Lavarda, Technician. He did a wonderful job and made the extra effort to clean both units inside and outside our home. It was a very hot day. However, Dan took his time and diligently took his time to make sure the outside units were perfectly cleaned. I highly recommend Doornbos and Technician Dan Lavarda.”
