Heater Maintenance: Simple Steps to Keep Your Home Warm

Feeling a chill in the house? Most of the time it isn’t the weather outside, but a tired heater that needs a little TLC. Regular maintenance can stop small problems from turning into costly repairs, and it only takes a few minutes each week. Below you’ll find practical tips you can do yourself, plus guidance on when to call a professional.

Weekly Quick Checks

Start with a visual scan. Make sure the heater’s power cord or gas line looks intact—no cracks, frayed wires, or loose connections. Turn the unit on and listen. A steady hum or gentle click means it’s running smooth; rattles or squeaks often signal loose parts.

Next, look at the filter or air intake screen. Dust builds up quickly, especially in households with pets or lots of foot traffic. A clogged filter forces the heater to work harder, raising energy bills. Remove the screen, give it a gentle tap, or rinse it with warm water. Let it dry completely before reinstalling.

If you have a hot water heater, check the pressure relief valve. Lift the lever briefly; you should hear a small burst of water. If nothing happens, the valve could be stuck and needs attention.

Seasonal Deep Clean

When summer fades and you’re ready for heating season, schedule a deeper clean. Turn off the power or shut off the gas supply first—safety first. For electric heaters, unscrew the front panel and vacuum out any dust using a soft brush attachment. For gas models, clean the burner ports with a soft brush or a thin piece of wire, being careful not to widen the opening.

Check the thermostat’s accuracy. Twist the dial a few degrees up and down while the unit is running; it should respond promptly. If it lags, replace the batteries or consider a new thermostat. A misreading thermostat can cause the heater to run nonstop, spiking your electricity or gas usage.

Don’t forget the flue or vent. A blocked vent can push carbon monoxide back into your home—a serious health risk. Use a flashlight to look for debris, nests, or soot buildup. If you notice any blockage, clear it with a garden hose or a flexible brush, and then test the exhaust with a carbon monoxide detector.

Finally, give the outer casing a wipe down with a damp cloth. Grease and grime can hide cracks that later turn into leaks. While you’re at it, tighten any loose screws you find.
