A Simple Heat Pump Maintenance Checklist for Homeowners

September 15, 2025

Keeping Your Heat Pump in Top Condition

Since heat pumps run for a significant portion of the year, providing both heating and cooling, staying on top of maintenance is especially important for this type of equipment. Old Glory Air Conditioning and Heating shares a helpful checklist for Arlington area homeowners.

Check and Replace Air Filters Regularly

Since heat pumps operate nearly year-round, filters tend to become dirty more quickly than in homes with separate, seasonal heating and cooling equipment. Checking filters monthly and replacing them as needed helps maintain proper airflow.

Keep the Outdoor Unit Clear

Regularly clearing leaves, debris, and vegetation away from the outdoor unit helps maintain proper airflow, which is essential to a heat pump's ability to efficiently transfer heat in both heating and cooling modes.

Monitor for Ice Buildup

While some frost during winter defrost cycles is normal, keeping an eye out for excessive ice buildup that doesn't clear on its own can help you catch developing issues before they become more significant problems.

Listen for Unusual Noises

Since heat pumps run so frequently, homeowners often become familiar with their system's normal operating sounds, making it easier to notice new or unusual noises that might indicate a developing issue worth having inspected.

Check Thermostat Settings Periodically

Confirming your thermostat settings and schedule remain appropriate for your household's current needs, and that the system responds correctly to adjustments, helps ensure everything is functioning as expected.

Schedule Professional Maintenance Twice Yearly

Given how frequently heat pumps operate throughout the year, professional maintenance visits, ideally twice yearly, help catch issues before they develop into more significant problems given the system's near-constant use.

Monitor Energy Bills for Unexplained Changes

Since heat pumps run consistently throughout the year, keeping an eye on your energy bills for unexpected changes can serve as an early indicator of developing efficiency issues.

Test Auxiliary Heat Function Periodically

If your heat pump includes an auxiliary heat backup system, periodically confirming it engages appropriately during colder weather helps ensure this backup function will be available when genuinely needed.

Keep Maintenance Records

Maintaining documentation of your maintenance visits helps protect manufacturer warranty coverage and provides a helpful record if you ever need to reference past service history.

Address Issues Promptly

Given how much your heat pump is relied upon throughout the year, addressing any developing issues promptly, rather than waiting, helps avoid more significant problems and potential discomfort from an unexpected breakdown.
