My mother waited a week to tell me that her heater wasn't working. I offered to check Angie's LIst for a HVAC technician, but she had already called a family friend who is a handyman. He was unable to get the heater to work, so he recommended a HVAC company. They came out determined the t-stat was bad and replaced it. The heater still did not work. They told her the heater probably was the original heater and may have just quit. They purchased a new furnace, installed it but determined that there was something wrong with the electrical supply. She then mentioned that her masterbath lights were not working either (on the same part of the house). The HVAC guys ran an extension cord to the furnace to get it to run. I decided to contact an electrician, and Tom Mallard was the first to get back to me. When he heard about the extension cord, he told me he would make every effort to get out the next day. He called ahead, as he said he would, and he determined that she had a some faulty GFI outlets. He completed the necessary repairs and replacements, and everything was working as it should when he left. He was also kind enough to give my mom a discount for paying cash. Tom was very professional, and I plan to use him again.
