Before Turning On Your Furnace

What to check for BEFORE turning your furnace on:

“Inman has been incredible. I contacted them for the exhaust flues connected to my furnace and water heater that had developed cracks and holes from rust. They responded to my service request immediately, showed up bright and early on the day they said, and fixed the flues the following day as promised. In addition, they cleaned up the new flues by separating them, and eliminating reducers. A much better installation.”
