"I was so impressed. They came out within 2 hours on a Saturday and had my furnace up and running, and didnâ t overcharge like companies on the TV adds! The service fee applied to fixing my furnace and there wasnâ t a ridiculous diagnostic fee that companies charge to read the code number the furnace provides them with. I was highly impressed."
