Blue Flame or The Gas company as it goes by Robert Spearing is operating without a license to install. He had a home service contract annually with us and we had no way to know. He installed a single stage furnace as a two stage Goodman furnace. When asked about it he pulled the first furnace and installed a two stage too small for the house with so many code violations found by the TSSA that it had to be replaced a third time by a different installer. Buyer beware who is coming to your home to do repairs, verify their license and credentials.
