Heat Pump Service and Maintenance 

Heat pumps are a smart, efficient way to stay comfortable year-round—but like any system, they need regular care to perform at their best.

We also help homeowners upgrade older heat pumps to newer, high-efficiency models that offer improved performance and lower operating costs.

Seasonal Heating Tune-Ups and Inspections

Routine maintenance prevents small issues from turning into costly breakdowns. Our seasonal heating tune-ups include thorough inspections, cleaning, and adjustments to ensure safe, reliable performance all winter.

During each visit, our technicians:

  • Inspect burners, ignitors, and safety controls
  • Test airflow and thermostat accuracy
  • Check for carbon monoxide leaks
  • Replace or clean filters
  • Clear drain lines and ensure proper ventilation

These steps help you save energy, extend your system’s lifespan, and maintain consistent indoor comfort.
