Had another company come out to look at my HVAC which wasn't cooling. They told me my system had to be replaced at a cost of $6600. The technician came out from Douglas, located the leak, repaired the leak at a reasonable price. Reliable company taking the time to look for the problem and solve it. Service: Repair HVAC

My boiler went out on Christmas Eve. Larry, from Douglas Heating, responded quickly and his fees were very reasonable. He didn't try to push and additional repairs that may be needed, but could wait for awhile. He is local. 847-417-1273 Douglas Heating

Douglas Heating was recommended by a roofer we called to handle the furnace flue and exhaust vents while the roofer corrected the flashing and installed new vents. Larry Crane inspected the attic and provided a proposal for the vent pipe installation and exhaust vent connection. Douglas heating also cleaned the flue pipe, which saved having a chimney sweep out later. They painted the exterior to match the roof (we supplied the paint). Two Douglas workers came out and worked with the roofer to complete their work in conjunction with the roofers. Worked out very well.
