Quick service. Brian was able to quickly diagnose the problem, he had parts available and was able to provide a reasonable quote and make the repair!
Brian was friendly and professional!
Mainstream is a company that I trust!

Anthony showed up on time and identified the issue right away. Sad that I need to purchase a new unit vs. Dumping more money into my old unit . Anthony talked us through the different options available and units we could purchase. Overall very knowledgeable tech and now waiting to get my new unit installed. I've been with Mainstream for many years and never had any negative issues.

Definitely recommend them. Couldn't have ask for a better experience from the polite person on the phone, the knowledge of the service tech (Brian) and the price of the service call. Satisfied customer.

I had routine maintenance done to my unit. Pete and Wesley showed up on time and talked with me about my concerns. In the past, John has come out and also did a great job on our repairs. All these guys are professional and do a great job. Samantha at the office is always nice and helpful also. Great company if you need hvac repairs or service.
