I have two very drafty rooms in my house (purchased in July 2017). Both rooms are above garage. I believe the ceiling above the garage is insulated however. Home inspection done prior to purchase noted some incomplete/unfinished duct-work in basement. This morning I noticed my house was cold, thermostat read 66. I had the temperature set at 73. Seems as though furnace could not provide enough heat. Furnace is older, installed around 1989/1990? May not be operating at full efficiency. Had a very high gas bill last month. I was hoping to have somebody come out and look at the furnace, duct-work, and garage insulation? Please give me a call so I can try to schedule something. Thank you.
