Heat Pump Maintenance Tips: What Homeowners Should Do (and When to Call a Pro)

Heat pumps work year-round to heat and cool your home, which makes routine maintenance essential for efficiency, comfort, and long-term reliability. Proper care helps prevent breakdowns, lowers energy costs, and ensures your system reaches its full lifespan.

Below is a clear, homeowner-safe guide to heat pump maintenance, including what you can do yourself and which tasks should always be handled by a licensed professional.

Quick Answer: How Do You Maintain a Heat Pump?

Basic heat pump maintenance includes changing air filters regularly, keeping the outdoor unit clear of debris, monitoring system performance, and scheduling professional maintenance at least once per year.

Homeowner Heat Pump Maintenance Checklist (Safe DIY Tasks)

These tasks are safe for most homeowners and should be performed throughout the year.

✅ 1. Change or Clean the Air Filter

• Check filters every 1–3 months
• Replace disposable filters or clean reusable ones
• Dirty filters restrict airflow, reduce efficiency, and impact indoor air quality

Tip:
Check the MERV rating of your filter. Higher ratings trap smaller particles, but the filter must be compatible with your heat pump to avoid airflow restriction.

✅ 2. Keep the Outdoor Unit Clear

• Maintain at least 2 feet of clearance on all sides
• Remove leaves, dirt, grass clippings, and debris
• Trim shrubs and mow carefully around the unit

Good airflow is critical for proper heat transfer and system efficiency.

✅ 3. Monitor System Sounds, Smells, and Performance

Pay attention to how your heat pump normally operates. Warning signs include:

• New or unusual noises
• Burning or musty odors
• Reduced heating or cooling output

Early detection helps prevent larger, more expensive issues.

✅ 4. Clear Snow and Ice Safely (Winter Tip)

• Keep snow from blocking airflow around the unit
• If light ice forms, turn the system off before clearing it
• Never chip ice off with tools or force components

If ice buildup keeps returning, professional service is recommended.

Heat Pump Maintenance Tasks That Require a Professional

Some maintenance steps should never be attempted by homeowners due to safety, environmental, and regulatory concerns.

⚠️ Refrigerant Evaluation

• Refrigerant levels must be measured with specialized tools
• Handling refrigerant requires EPA certification
• Low refrigerant usually indicates a leak that must be repaired

If performance drops, call a licensed HVAC technician.

⚠️ Condensate Drain & Electrical Inspections

• Clogged drains can cause water damage
• Electrical components require trained inspection
• Improper handling can damage the system or create safety hazards

⚠️ Coil Cleaning & Internal Component Service

• Indoor and outdoor coils require professional cleaning
• Improper cleaning can reduce efficiency or cause damage

How Often Should You Schedule Professional Heat Pump Maintenance?

Most manufacturers and energy experts recommend:

• One professional maintenance visit per year
• Some homes benefit from biannual service due to year-round operation

Professional maintenance helps:

• Maintain warranty compliance
• Improve efficiency
• Reduce the risk of unexpected breakdowns

According to the Indoor Air Quality Association (IAQA), proper HVAC maintenance can help reduce energy costs by up to 30%.

What Happens During a Professional Heat Pump Maintenance Visit?

During a routine maintenance visit, a licensed technician will typically:

• Inspect and clean indoor and outdoor components
• Evaluate refrigerant performance and system pressures
• Check thermostat accuracy and system controls
• Inspect electrical connections and safety components
• Identify current or potential issues early
