pretty good customer service. They also have after hours customer service if your furnace goes out and its -20 below. Good prices on the yearly inspections. I remember when the furnace kept going out and I called them at like one in the morning and they sent someone out to fix it. They didn't even charge me as it was an emergency because I my son was just an infant at the time.
PROS: after hours customer service
CONS: might get a cheaper estimate somewhere else.
