Quick answer
A heat pump tune-up in the Burlington, Oakville and Hamilton area runs $120–$250 per visit. Because a heat pump both heats and cools, it ideally gets two visits a year — spring for cooling, fall for heating — so a maintenance plan at $150–$350 per year usually costs about the same as, or less than, two separate visits and adds priority service. Filters and keeping the outdoor coil clear are on you.
Heat pump maintenance cost is simple to state and worth breaking down: a standalone tune-up at $120–$250, or a plan at $150–$350 a year that covers both seasonal visits. What matters more is what those visits actually include, because a heat pump has parts an air conditioner does not, and a tune-up that only rinses the coil misses all of them.
What a proper heat pump tune-up includes
- Refrigerant charge verified by subcooling and superheat rather than topped up by feel — the charge is the biggest single driver of efficiency and compressor life.
- Defrost cycle forced and timed, with the defrost sensor and control board checked.
- Reversing valve operation confirmed in both heating and cooling.
- Outdoor coil cleaned and bent fins straightened; fan motor and blade inspected.
- Capacitor and contactor tested under load; electrical connections tightened.
- Indoor coil and condensate drain inspected; condensate pump tested if there is one.
- Blower airflow and static pressure measured against what the equipment requires.
- Thermostat staging, compressor lockout and backup-heat settings reviewed. The fall visit is where a badly set lockout gets caught before it costs you a winter of unnecessary gas or strip heat.
- Filter replaced or checked, and the size noted for you.
Spring visit, fall visit, or both?
Both, if you can. The spring visit is essentially an AC tune-up. The fall visit is the one an air conditioner never needed: defrost, backup heat and heating-mode charge. If you only do one, make it fall. A defrost fault found in October is a scheduled repair; the same fault found in January means running on expensive backup heat while you wait for the part.
That two-visit reality is why a plan is the sensible way to buy heat pump maintenance. Two standalone tune-ups at $120–$250 each cost about the same as, or more than, a plan at $150–$350 per year, and the plan adds priority scheduling when the whole city calls at once. Are HVAC maintenance plans worth it runs the arithmetic in detail.
What you might pay beyond the tune-up
- Diagnostic visit when something has failed: $90–$150, credited toward the repair at ZK Mechanical.
- Common repairs found during a tune-up: capacitor or contactor $150–$350; outdoor fan motor $300–$700; control board $400–$800.
- Refrigerant leak repair and recharge: $300–$800+, more if the leak is inside the coil.
- Filters: a few per year. Budget for the pleated size your air handler takes rather than the cheapest fibreglass one, which lets dust through to the indoor coil.
- The return on all of it shows up on the hydro bill, which how much electricity does a heat pump use puts in context.
Maintenance you should do yourself
- Change the filter every one to three months — more often with pets, or in a newer Waterdown or Alton Village build where construction dust is still working its way out of the ducts.
- Rinse the outdoor coil with a garden hose, power off, after cottonwood season in June and again after the leaves come down in November.
- Keep snow and ice clear of the unit all winter, and never let it sit under a dripping eavestrough.
- On a ductless system, wash the mesh screens in each indoor head monthly during heavy use.
- In summer, check that the condensate drain is running clear; a backed-up drain trips the float switch, if one is fitted, on the hottest day of the year — and overflows onto the furnace if one is not.
Ductless heat pumps cost the same to maintain, with one extra job
A ductless system is priced the same per visit, but the indoor heads build up a film on the blower wheel and coil that the washable screens do not catch. Every few years each head needs a proper deep clean, opened up and bagged so the rinse water is contained, which is a separate job from the seasonal tune-up. Skipping it is the usual reason a five-year-old head in a Kerr Village apartment or a Dundas addition starts to smell musty and blow weaker air.
Does skipping maintenance void the warranty?
It can complicate a claim. Several manufacturers' warranty terms require the unit to be maintained by a licensed contractor and allow them to ask for records on a compressor claim. Keep the tune-up invoices in the same folder as the registration confirmation and the installation invoice.
