i was not super impressed with their A/C repair service which was okay, but new installation and maintenance seem adequate. You can call the owner and ask for help or special care if you need it.

They have gotten more expensive over the years (about 10) we've used them, but they are responsive and knowledgable.

I have been very satisfied with the work of United Service Specialists (formerly known as A.B. Chelini) over the last several years, installing and servicing several HVAC units The company and its staff have been very pleasant to deal with. The company will send a text when the technician is on the way and you can even track the technician's distance from your home. In particular, the technician Carlos is great - knowledgeable, friendly, and prompt.
