Heat Pump Maintenance: Simple Tips to Protect Your Investment

Thinking about installing an air source heat pump — or already enjoying the comfort of one in your home? Modern systems are designed to be reliable, energy-efficient, and low-maintenance. In fact, heat pump maintenance is surprisingly simple. With a few easy upkeep steps and an annual professional tune-up, you can protect your investment and keep your system running efficiently for years.

Why Heat Pump Maintenance Matters

Routine heat pump maintenance helps:

• Maintain peak energy efficiency
• Lower utility bills
• Prevent unexpected breakdowns
• Extend the life of your system
• Keep heating and cooling performance consistent

The good news? Most maintenance tasks are quick and easy for homeowners to handle.

Keep Your Indoor Units (Heads) Clean

One of the most important parts of heat pump maintenance is cleaning the indoor air filters.

Check your filters every 1–3 months. During high-use seasons — especially if you have pets or smoke indoors — you may need to clean them more frequently.

To clean your heat pump filter:

1. Turn off the system.
2. Remove the filter from the indoor unit.
3. Vacuum with a brush attachment.
4. Wash gently with soap and warm water.
5. Allow it to dry completely before reinstalling.

Clean filters improve airflow, increase system efficiency, and help prevent strain on the equipment.

Keep the Outdoor Unit Clear and Unobstructed

Your outdoor heat pump unit needs proper airflow to operate efficiently. This is especially important in Massachusetts, where falling leaves, ice buildup, and heavy snowfall can affect performance throughout the year.

As part of regular heat pump maintenance:

• Remove leaves, sticks, and debris.
• Trim bushes and vegetation at least two feet away.
• After snowstorms, clear snow from all sides of the unit.
• Avoid stacking items or covering the unit.

Maintaining clear airflow helps your system run efficiently and prevents unnecessary wear.

Maintain Good Airflow Inside Your Home

If you have a ducted heat pump system:

• Keep supply and return registers clean.
• Straighten bent fins.
• Avoid blocking vents with furniture or rugs.

Good airflow throughout your home improves comfort and system performance.

Schedule Annual Professional Heat Pump Service

Even though heat pump maintenance is minimal, an annual professional inspection is strongly recommended.

Have a licensed HVAC technician service your system once per year — ideally before the heating season begins.

During a professional heat pump tune-up, a technician will:

• Inspect and clean internal components
• Check refrigerant levels
• Identify and seal potential leaks
• Test electrical connections
• Confirm proper operation

Annual service protects efficiency, helps prevent costly repairs, and ensures your system continues delivering reliable heating and cooling.

Heat Pump Maintenance Is Simple — and Worth It

Heat Pump Maintenance FAQ

How often should I clean my heat pump filter?

Check and clean your heat pump filters every 1–3 months. During heavy-use seasons or if you have pets, you may need to clean them more often. Dirty filters restrict airflow, reduce efficiency, and put extra strain on your system.

How often does a heat pump need professional maintenance?

Heat pumps should be professionally serviced once a year, ideally before the heating season starts. A licensed technician will check refrigerant levels, inspect electrical connections, clean internal components, and confirm that the system is running properly.

Is heat pump maintenance difficult?

Not at all. Most heat pump maintenance is simple enough for homeowners to handle — mainly keeping filters clean and the outdoor unit clear of debris. The only task that requires a professional is the annual tune-up.

Do I need to clear snow from my heat pump in winter?

Yes. After snowstorms, clear snow and ice from all sides of your outdoor unit to maintain proper airflow. In Massachusetts, this is one of the most important seasonal maintenance steps you can take to keep your heat pump running efficiently through the winter.
