Furnace Blowing Cold Air? 7 Causes Coppell Homeowners Should Know

A furnace usually blows cold air because the blower is running while the burners are off. The cause is often a thermostat fan set to ON, a clogged filter that tripped the limit switch, or a failed ignition, gas, or condensate safety. Check the thermostat and filter first, and leave gas parts to a pro.

Furnace Carbon Monoxide Warning Signs for DFW Homes

Headache, dizziness, nausea and confusion that ease when you leave the house are the main body warnings. Soot, a yellow burner flame, rust on the flue pipe and window moisture are clues on the furnace. Only a working CO alarm is a reliable warning, because the gas has no smell or color.

Leaking Attic Supply Plenum in Fort Worth: Why Tape Won't Hold It

The supply plenum is the box on your air handler that feeds every supply duct. When its seams pull apart in the attic, cooled air blows into the attic instead of your rooms, so the system runs longer and the far rooms stay warm. Tape will not hold a split joint. A lasting fix is a plenum, usually sheet metal, that is screwed on, supported on its own and sealed with mastic.

Burning Smell When the Heat Comes On in Argyle? Normal or Not

A light, dusty burning smell that fades within an hour or two of the first heat of the season is normal. An electrical or plastic smell, or any odor that keeps coming back, is not normal: switch the system off at the thermostat and its breaker, then call a pro. A rotten egg smell means gas, so leave the house and call the gas company or 911 from outside.

Furnace Won't Turn On in Southlake? Check These Before You Call

Check those first, in order. If you smell gas or a carbon monoxide alarm sounds, leave and call from outside.
