Last night we tried to start the furnace for the first time this season, and couldn't get it going. This morning I called Cozy World, because of their wonderful reviews on Homestars. Fred came out within an hour of the call, fixed the problem (thermostat related, as it turned out), checked over the rest of the furnace, and now my only problem is getting our cats off the vents so the house can get some heat. I will certainly call Cozy World for any future HVAC problems. Thanks, Fred!
