Heat pump tune-ups from Home Comfort Alliance
A heat pump tune-up from Home Comfort Alliance costs $230, or $180 for Home Comfort Club members (prices as of September 2026). The U.S. Department of Energy recommends professional service at least once a year. In western Washington a heat pump heats for most of the year, so fall is the visit that matters most. We service ducted heat pumps and ductless mini-splits of all major brands from our Sumner, Redmond, Everett and Bremerton teams.

What does a heat pump tune-up cost?
| Service | Price |
|---|---|
| Heat pump tune-up, per piece of equipment | $230 |
| Heat pump tune-up, Home Comfort Club member price | $180 |
| Current offer | 10% off a heat pump tune-up, at non-member pricing |
Prices as of September 2026. The offer cannot be combined with any other offer or with Club pricing, and is not valid for the trip charge or diagnostic fee. See current offers.
The price is per piece of equipment, and we confirm what your home has when you book. If the technician finds something that needs a repair, you get a written price first, and nothing is done until you approve it.
For context, national estimates put basic heat pump maintenance at $80 to $150 a year and mini-split maintenance at $300 to $550 (Angi, July 2026); This Old House lists $75 to $150 and $300 to $550 (June 2026). These are third-party figures, not our prices.
How often should a heat pump be serviced?
At least once a year, according to the U.S. Department of Energy. Book it in the fall, before the heating season, because your heat pump heats most of the year here. ENERGY STAR suggests checking heating in the fall and cooling in the spring, so a second spring visit makes sense if you run it hard for cooling in summer heat.
| System | Professional visit | Your job between visits |
|---|---|---|
| Ducted heat pump | Once a year, in the fall; add spring if you cool a lot | Check the filter monthly; keep the outdoor unit clear |
| Ductless mini-split | Once a year, including the indoor units | Clean the indoor unit filters about monthly while it runs |
| Hybrid (heat pump with a furnace) | Once a year, covering both the heat pump and the furnace | Check the filter monthly; keep the outdoor unit clear |
What a heat pump tune-up should cover
This list comes from the U.S. Department of Energy and ENERGY STAR. Ask any contractor which of these they do on your visit.
| # | Task | Source |
|---|---|---|
| 1 | Inspect ducts, filters, blower and indoor coil for dirt and blockages | DOE |
| 2 | Check the filter, and clean or replace it | DOE, ENERGY STAR |
| 3 | Measure airflow | DOE |
| 4 | Verify the refrigerant charge by measurement | DOE |
| 5 | Check for refrigerant leaks | DOE |
| 6 | Inspect, clean and tighten electrical connections; measure voltage and current on motors | DOE, ENERGY STAR |
| 7 | Lubricate motors and inspect belts | DOE, ENERGY STAR |
| 8 | Confirm heating is locked out when cooling is called for, and the reverse | DOE |
| 9 | Check thermostat operation and settings | DOE, ENERGY STAR |
| 10 | Check the start-up and shut-off controls | ENERGY STAR |
| 11 | Clean the indoor and outdoor coils | ENERGY STAR; DOE (outdoor coil when dirty) |
| 12 | Check and clear the condensate drain | ENERGY STAR |
| 13 | Clear debris and plants from around the outdoor unit | DOE |
| 14 | Look for duct leaks | DOE |
Two heat pump items worth asking about as well: a check that the defrost cycle runs and clears frost from the outdoor coil, and a check of the backup (auxiliary) heat.
Why heat pumps need different care than a furnace
A furnace works one season; a heat pump heats and cools, so it runs most of the year. Its outdoor unit sits in our damp weather all winter and has to defrost its coil to keep heating. Its refrigerant charge and airflow matter in both modes, and its electrical parts, such as capacitors and contactors, live outdoors. That is why a heat pump visit covers more than a furnace visit. For furnace and AC tune-ups, see HVAC maintenance and tune-ups.
Ductless mini-split maintenance
Clean the indoor unit filters about once a month while the system runs (Angi, July 2026), or as your owner's manual says; filter cleaning is the owner's job under the manufacturers' instructions. Once a year, a technician should clean the indoor coil, blower wheel and drain line and check the outdoor unit.
Signs an indoor unit needs cleaning: a musty smell when it starts, weaker airflow, or water dripping from the unit. Home Comfort Alliance is a Mitsubishi Electric Diamond Dealer and services all major ductless brands. See ductless systems.
A recent ductless cleaning in Seattle
In September 2026 one of our HVAC technicians cleaned a single-head ductless mini-split in Seattle's Central District. Dust and grime build up on a mini-split's indoor coil and blower wheel where a filter rinse can't reach, so the technician gave the indoor unit a hydro jet cleaning, which flushes debris out of the coil and blower so the unit runs efficiently and the blower lasts longer.
Does skipping maintenance void your heat pump warranty?
Usually not on its own, but it can cost you coverage. The manufacturer warranty pages we checked tie the length of coverage to registering the equipment on time, and warranties generally don't cover damage caused by neglected or improper maintenance. Read your own warranty, keep your service records and register within the window.
| Brand | Register within | What registration gets you |
|---|---|---|
| Carrier | 90 days | A choice of 10-year parts-only coverage, or 5-year parts plus 3-year labor on eligible equipment. After 90 days: standard 5-year parts coverage |
| Lennox | 60 days (not required in California or Quebec) | Registration is required for the full limited warranty |
| Mitsubishi Electric | 90 days | 12-year parts and compressor coverage when installed by a Diamond Contractor or Ductless Pro in a single-family home the owner lives in |

Is a heat pump tune-up worth it?
The U.S. Department of Energy says the difference in energy use between a well-maintained heat pump and a severely neglected one ranges from 10% to 25%. A yearly visit also catches small problems before a cold snap and gives you the service records a warranty claim may need.
If your system is new and you keep the filters and outdoor unit clean, a yearly fall visit is enough. You don't need two paid visits a year unless you also cool heavily in summer.
Book a heat pump tune-up$230, or $180 for Home Comfort Club members.
What you can do between visits
- Check filters monthly, and clean or change them every 3 months or as the manufacturer recommends. Ductless filters: about monthly while in use.
- Keep leaves, plants and snow clear of the outdoor unit, with the power off before you touch it.
- Gently clean the outdoor coil when it looks dirty.
- Don't set the thermostat back so far that the backup heat comes on.
- Use the "auto" fan setting.
- Keep supply and return vents open and clear.

- Ice stays on the outdoor unit after a defrost cycle
- It runs all the time without reaching the set temperature
- The breaker trips

Heat pump maintenance FAQ
How much does a heat pump tune-up cost?
A heat pump tune-up from Home Comfort Alliance is $230 per piece of equipment, or $180 for Home Comfort Club members (prices as of September 2026). Right now we also offer 10% off a heat pump tune-up at non-member pricing. The offer can't be combined with other offers and doesn't apply to trip or diagnostic fees.
How often should a heat pump be serviced?
At least once a year, as the U.S. Department of Energy recommends. In the Seattle-Tacoma area, book it in the fall, because your heat pump heats most of the year. Add a spring visit if you use it a lot for cooling.
Do heat pumps need service twice a year?
Not always. The Department of Energy says at least once a year. ENERGY STAR suggests checking heating in the fall and cooling in the spring, so a second spring visit makes sense if you use your heat pump a lot for cooling in summer.
What is included in a heat pump tune-up?
The Department of Energy lists inspecting ducts, filters, blower and indoor coil, measuring airflow and refrigerant charge, checking for leaks, tightening electrical connections, lubricating motors and checking the thermostat and controls. Ask us what your visit covers when you book.
Does skipping maintenance void my heat pump warranty?
Usually not by itself, but damage caused by neglected or improper maintenance generally isn't covered, and registration deadlines decide how long coverage lasts. Carrier and Mitsubishi Electric ask you to register within 90 days, and Lennox within 60 days. Keep your service records.
How much does it cost to clean a ductless mini-split?
National estimates put yearly mini-split maintenance at $300 to $550 (Angi, July 2026). Our heat pump tune-up is $230, or $180 for Club members. The tune-up price is per piece of equipment.
How often should I clean my mini-split filters?
Clean the indoor unit filters about once a month while the system is running (Angi, July 2026), or as your owner's manual says. A technician should clean the coil, blower wheel and drain line once a year.
What heat pump maintenance can I do myself?
Check filters monthly and clean or change them every 3 months or as the manufacturer recommends. Keep the outdoor unit clear of leaves, plants and snow (turn the power off first), use the "auto" fan setting, and keep vents and returns open.
Is ice on my heat pump normal?
A light frost that clears during a defrost cycle is normal in cold, damp weather. Thick ice that stays, or a unit that stops heating, needs a repair visit. See our heat pump repair page for what to check first.
Do you service all heat pump brands?
Yes. We service all major brands, ducted and ductless. Home Comfort Alliance is a Mitsubishi Electric Diamond Dealer, a Carrier Factory Authorized Dealer and a Lennox Premier Dealer.
What happens if the technician finds a problem?
We explain what we found and give you a written price before any repair. Nothing is done until you approve it. Our trucks are fully stocked, so most repairs can be handled on the spot.
Is the Home Comfort Club worth it for a heat pump?
The Club's HVAC plan is $15 a month. Members pay $180 instead of $230 for a heat pump tune-up and get priority scheduling and member pricing on repairs. Club members with a new system installed by Home Comfort Alliance get extended labor coverage for up to 5 years from installation. Memberships can't be cancelled in the first 12 months.
