Heat Pump Maintenance That Keeps Your Home Comfortable All Year

A heat pump does twice the work of a traditional HVAC system. Our maintenance keeps it efficient, reliable, and ready for whatever Northern Virginia weather brings.

Why Heat Pump Maintenance Matters More Than You Think

Heat pumps work harder than most HVAC systems. They heat your home in winter, cool it in summer, and run almost nonstop during the months in between. When one system carries that much responsibility, even small issues can lead to higher utility bills, uneven temperatures, or unexpected breakdowns.

That’s why our maintenance isn’t a quick once-over. We take a preventive, diagnostic approach designed specifically for heat pumps and the way they operate in both heating and cooling modes. Before we begin any work, we start with a conversation about how your system has been performing—any changes in comfort, airflow, noise, or efficiency. This gives us a complete picture so we can tailor the visit to your home and catch issues long before they impact your comfort.

AC Repair

What’s Included in a Dave’s Heat Pump Maintenance Visit

A trained technician will:

  • Test electrical components and ensure safe operation

  • Measure refrigerant pressures and check for leaks

  • Inspect the reversing valve and system’s ability to switch modes

  • Verify proper defrost cycle activation

  • Clean indoor and outdoor coils to improve airflow

  • Clear drain lines and check for potential water issues

  • Lubricate moving components (when applicable)

  • Tighten connections and inspect wiring

  • Test thermostat accuracy and communication

  • Evaluate system efficiency in both heating and cooling modes

Your technician will wrap up with a full report — what we found, what we fixed, and what may need attention down the road.

Seasonal Maintenance: Twice a Year Keeps Your System Strong

Some homeowners are surprised to learn that heat pumps need more maintenance than a traditional HVAC setup. Since they run in all seasons, we recommend:

  • Spring maintenance to prepare for cooling season

  • Fall maintenance to prepare for heating season

This schedule keeps performance high and reduces strain on the system.

The Benefits of Staying on a Maintenance Schedule

  • Lower energy use — a clean, tuned system doesn’t have to work as hard
  • More consistent temperatures throughout your home
  • Fewer emergency repairs during peak weather
  • Longer system lifespan due to reduced wear
  • Healthier indoor air thanks to improved airflow and cleaner coils

Our job isn’t just to tune your system — it’s to protect it.

If we spot a failing capacitor, refrigerant leak, electrical fault, or airflow restriction, we’ll show you exactly what’s going on and help you decide the best next step. Catching issues early can save you hundreds in repair costs.
