Cold Front Coming to DFW? How to Keep Your Home Warm and Your Heater Running Safely

North Texas weather can swing from 85 degrees to freezing in a matter of days, and the first real cold front of the season is when most heating problems show up. Furnaces and heat pumps that haven't run in months are suddenly asked to work around the clock, and that's exactly when worn parts fail.

Before the temperature drops, do a quick check. Replace your air filter, since a clogged filter restricts airflow and forces your system to work harder. Make sure vents and returns aren't blocked by furniture or rugs. Then run your heat for a few minutes now, while it's mild, so you can catch strange smells, odd noises, or a system that won't start. A faint dusty smell for the first few minutes is normal; a persistent burning smell, banging, or no heat at all is not.

Once the cold arrives, set your thermostat to a steady temperature rather than turning it up and down. If you have a heat pump, avoid big jumps in the setpoint, because that triggers the backup (auxiliary) heat strips, which use a lot more electricity. Close doors to rooms you aren't using, keep curtains closed at night to hold in warmth, and seal obvious drafts around doors and windows.

Safety matters as much as comfort. Never use an oven or stove to heat your home, and be careful with space heaters: plug them directly into a wall outlet, keep them away from anything flammable, and never leave them running unattended. If you have a gas furnace, make sure you have working carbon monoxide detectors, and if the alarm sounds, get everyone outside and call for help immediately.

If the temperature is expected to hit freezing, protect your pipes too. Open cabinet doors under sinks on exterior walls, let faucets drip slightly during a hard freeze, and disconnect outdoor hoses. If your heater stops working or you notice anything unusual, don't wait for it to get worse.
