"Called on a Saturday night when our AC died during a heat wave. Technician was there in 90 minutes and had us cold again within 2 hours. Fair pricing and professional."

"Replaced our 20-year-old furnace. Summit gave us the best quote by $2K and had it installed in one day. Couldn't be happier with the work."
