Very professional, very helpful! Our A/C unit stopped working during the heat wave 9÷14÷2012−9÷15÷2012, and I left them a message on Sunday(I chose not to make it an emergency call) and they came out on Monday. They explained the problem — a blown capacitor — and replaced it immediately. He also expained that during times of high usage and during blackouts, that the power can have surges, and the capacitor’s will typically blow. He suggested if the power ever goes out to turn off the A/C to protect it. Monday night we came home and the A/C was working like a champ, thank you G-Force! We chose them based on their ranking on the Goodman(they make A/C units) web site. It lists them with the following: Financing, 24h Service, GoodCare Extended Service Plan, Free Estimates, Indoor Air Quality, NATE — North American Technician Excellence.
