Report

I was very impressed with the service I received from Terri-O. Luis Velazquez did a great job finding out what was causing my air conditioner to not work and fixing the problem. I would definitely use Terri-O again and will recommend them to my family and friends.

Report

I want to commend the crew that came and repaired our AC. My wife has been a cancer survivor since 1995 and the ill effects of the radiation and chemo has caused her to extra sensitive to any heat. Your crew was professional, timely and very friendly. We will use Terri-o, from now on.
