Heat Pump Maintenance & Repair Cost

A heat pump handles both heating and cooling. HomeGuide puts a tune-up at $70 to $200. Angi's figure for a yearly tune-up is $50 to $180.

Maintenance prices

HomeGuide says maintenance plans typically include tune-ups, filter changes, priority service and 5% to 15% off repairs.

Repair prices

HomeGuide puts minor repairs at $150 to $650 and major out-of-warranty repairs, such as a compressor, condenser or evaporator coil, at $650 to $2,500+. Angi's HVAC repair guide lists heat pump repairs at $200 to $2,000.

Repair or replace?

A heat pump compressor out of warranty costs $1,300 to $2,500 (HomeGuide). Angi puts a full heat pump replacement at $4,236 to $7,942 for most homeowners. On an older unit, compare both. See heat pump cost.

Why heat pumps need regular service

A heat pump runs for both heating and cooling, so it often works more hours each year than an air conditioner alone. That makes routine maintenance more important.

What a maintenance visit includes

• Cleaning the outdoor coil and checking the fan.
• Checking refrigerant charge and looking for leaks.
• Testing the reversing valve and defrost controls.
• Inspecting electrical parts, such as capacitors and contactors.
• Checking the indoor coil, blower and condensate drain.
• Testing backup heat strips.

What you can do yourself

• Change or clean the air filter on schedule.
• Keep plants, leaves and debris clear of the outdoor unit.
• Keep supply and return vents open and unblocked.
• Watch for ice that stays on the outdoor unit for a long time. Short periods of frost are normal; constant ice is not.

What affects the price

• One visit or a yearly plan.
• Number of systems in the home.
• Ductless systems with several indoor heads, which take longer to clean.
• Parts and refrigerant, which are usually extra.

Questions to ask

1. How many visits a year do you recommend for a heat pump?
2. Do you test the defrost cycle and backup heat?
3. What is included in your maintenance plan, and what is extra?

In Texas

Because Texas heat pumps cool for most of the year, a spring visit before the long summer is especially valuable. A second visit in the fall checks the heating side before the first cold snap.

Why heat pumps need service twice a year

A heat pump heats and cools the house with the same equipment, so it runs in both summer and winter. An air conditioner rests through the winter and a furnace rests through the summer, but a heat pump does both jobs and gets more hours of use each year. That is why many manufacturers and contractors recommend two maintenance visits: one in spring before the cooling season and one in fall before heating starts.

What a technician checks

Outdoor unit. The condenser coil is cleaned, the fan motor and blades are checked, and the capacitor, contactor and electrical connections are tested. The technician checks the refrigerant pressures and temperatures in the current mode.

Reversing valve. This valve switches the heat pump between heating and cooling. The technician confirms it changes over correctly. A valve that sticks can leave the system stuck in one mode.

Defrost system. In cold weather, frost forms on the outdoor coil, and the heat pump runs a defrost cycle to melt it. The technician checks the defrost controls and sensors so the unit does not ice up in winter.

Auxiliary heat. Most heat pumps have backup electric heat strips in the indoor unit. The technician tests them, because they are the backup when it is very cold and they use a lot of electricity if they run more than needed.

Indoor unit. The air filter, blower motor and wheel, evaporator coil and condensate drain are checked and cleaned as needed.

Thermostat. The settings for heat pump and auxiliary heat are checked so the backup heat does not turn on too early.

What you can do between visits

• Change or clean the air filter on schedule.
• Keep the outdoor unit clear of leaves, snow, ice and plants, with space on all sides for airflow.
• Make sure the outdoor unit stays level. A tilted unit can affect drainage and defrost.
• Do not cover the unit in winter. It needs airflow to run.
• Watch for ice that builds up and stays on the unit for hours, which means the defrost system needs attention.

Signs your heat pump needs service now

• The house is not reaching the thermostat setting.
• The auxiliary or emergency heat light comes on often in mild weather.
• The outdoor unit stays covered in ice.
• Loud noises, rattles or grinding.
• Higher electric bills without a change in use.

Catching these early often means a smaller repair.

Maintenance plans for heat pumps

Because heat pumps need two visits a year, a maintenance plan that includes both visits can save money compared with paying for each visit separately. Compare what is included and whether repair discounts or priority service are part of the plan.

Cost of skipping maintenance

Skipped maintenance can lead to dirty coils, low refrigerant going unnoticed, failing capacitors and defrost problems. These raise energy bills and can lead to compressor damage, which is one of the most expensive repairs. A heat pump that runs year-round benefits from maintenance more than equipment that runs only one season.

Choosing a technician

Ask whether the technician regularly services heat pumps, not only air conditioners and furnaces. Heat pumps have parts, like the reversing valve and defrost controls, that a technician who mainly works on other equipment may check less carefully. Asking for the checklist the company uses on heat pumps is a simple way to compare. Keep each visit's checklist so you can compare readings from year to year.
