Our techs see these failures every winter. We carry the parts that fix them on the first visit.

Furnace will not turn on

Furnace blows cold air

We diagnose the high-limit switch and replace the clogged filter or blocked duct that caused the trip.

Loud banging or grinding noise

We isolate the inducer motor, blower wheel or heat exchanger and quote the repair before parts go in.

Yellow or flickering pilot light

We test for carbon monoxide and clean or replace the flame sensor and gas valve as needed.

Short cycling (turns on and off)

We rebalance the thermostat, check the flame rod and verify static pressure across the duct system.

Red tagged by the gas company

We provide a free second opinion on every TSSA red tag and remove it the same day when safe to do so.
