Heat Pump Maintenance Guide

Keep your heat pump running at peak efficiency year-round with this seasonal maintenance guide. Regular care extends the life of your system, lowers energy bills, and prevents costly emergency repairs.

Spring Maintenance

March – May

Spring is the ideal time to prepare your heat pump for the cooling season ahead. After months of heavy heating use, a thorough checkup ensures your system runs efficiently all summer.

Summer Maintenance

June – August

Maine summers are getting warmer, and your heat pump doubles as an efficient air conditioner. Keep it running smoothly with these mid-season checks.

Fall Maintenance

September – November

Fall is your last chance to prepare before Maine's harsh winter. These steps ensure your heat pump is ready to handle sub-zero temperatures efficiently.

Winter Maintenance

December – February

Maine winters test even the best heat pumps. Regular monitoring and a few simple habits will keep your system running efficiently through the coldest months.

Year-Round Best Practices

  • Keep a maintenance log — note filter changes, professional visits, and any unusual behavior.

  • Register your heat pump with the manufacturer for warranty coverage and recall notifications.

  • Consider a maintenance plan with your installer for discounted annual tune-ups and priority service.

  • Use a programmable or smart thermostat to optimize comfort and efficiency automatically.

  • Seal air leaks around windows and doors — your heat pump works less when your home retains heat better.

When to Call a Professional

Some issues require a certified HVAC technician. Contact Hita immediately if you notice:

  • A significant drop in heating or cooling performance
  • Water leaking from the indoor unit
  • Error codes displayed on the unit or remote control
  • Electricity bills that spike beyond normal seasonal variation
