Simple Maintenance Checks Homeowners Can Do Each Season

Here are some things things you can do each season to help refuce energy bills.

Spring (get ready for cooling)

• Replace the HVAC air filter and write the date on the frame so you remember.

• Clear debris from around the outdoor unit (leaves, weeds, tumbleweeds), keeping at least 2 feet of open space for airflow.

• Gently rinse the outdoor coil from the outside in with a light hose spray (no pressure washer).

• Make sure supply vents and return grilles inside are open and not blocked by furniture or rugs.

• Test the thermostat: switch to “Cool,” confirm the system starts, and listen for unusual noises.

Summer (keep it running efficiently)

• Check the filter again mid-season—summer run time clogs filters faster.

• Walk the house and feel for weak airflow rooms; a new issue may indicate a restriction or duct problem.

• Look for ice on refrigerant lines or the outdoor coil—icing often points to airflow problems or low refrigerant.

• Keep blinds/curtains closed during peak sun to reduce heat load and runtime.

Fall (prep for heating)

• Replace the filter before heating season starts.

• Test the heat early (before the first cold snap) so there’s time to fix issues without emergency pricing pressure.

• Make sure gas furnace areas are clear and vents aren’t blocked; keep storage away from the unit.

• If you smell a strong or persistent burning odor after startup, shut it down and get it checked.

Winter (reduce strain and prevent emergencies)

• Keep return air paths open (don’t close too many doors/vents), so airflow stays balanced.

• Watch for dry air or stuffy rooms—this can hint at airflow/filtration problems.

• If the system short-cycles (turns on/off frequently), don’t ignore it; that wastes energy and wears parts.

A few “often missed” spots

• Bathroom and kitchen exhaust fans: stuck dampers can leak air.

• Attic access doors: poor sealing lets conditioned air escape.

• Dryer vent area: gaps around the wall penetration are common leakage points.

• Thermostat location: if it’s in direct sun or near a draft, it can cause unnecessary runtime.

When to stop DIY and call a pro

Call for service if you notice:

• Ice on the indoor/outdoor coil or refrigerant lines

• Burning/electrical smells, buzzing, or repeated tripping breakers

• Water pooling around the indoor unit

• Major airflow changes or rooms suddenly not cooling/heating
