A heat pump works all year, so once-a-year care is the minimum — twice is better.
A furnace rests all summer. A heat pump does not: it heats your Richmond home through the damp winter, then reverses and cools it through July and August. That double duty is exactly why it is efficient, and exactly why it needs a real maintenance plan instead of an occasional look when something sounds wrong. A good plan is simple: two professional visits a year, timed for spring and fall, plus a few five-minute homeowner checks in between. Do that, and the system stays efficient, quiet, and far less likely to fail on the coldest or hottest weekend of the year.
Six things a heat pump maintenance visit should actually include.
Not all tune-ups are equal. A quick filter swap and a hose-down is not a maintenance visit. Here is what should happen when a technician services a ducted or ductless heat pump in Richmond.
1. Clean coils, inside and out
The outdoor coil in Richmond collects cottonwood fluff in late spring, leaf litter in fall, and a fine film of salt-tinged grime if you live near Steveston or the West Dyke. The indoor coil collects dust and household film. Dirty coils force the system to run longer to move the same heat, which shows up directly on your BC Hydro bill. Both coils should be inspected and cleaned as needed at each visit — not just rinsed from the outside.
2. Refrigerant charge checked properly
A heat pump is a sealed system. If the charge is low, there is almost always a leak, and simply topping it up without finding that leak is money spent twice. A proper visit measures pressures and temperatures against the manufacturer's specification for brands like Daikin, Mitsubishi Electric, Fujitsu, Midea, and Lennox, and if the charge is off, talks about leak detection before any refill. Low charge is also a common cause of icing — see our guide to why a heat pump freezes up.
3. Condensate drain cleared and tested
Richmond sits low, and many rancher and split-level homes here have indoor units and air handlers where a blocked drain has nowhere forgiving to go. In cooling season a heat pump pulls a surprising amount of moisture from the air, and algae or dust can plug the drain line until water backs up into the unit or the ceiling below it. Clearing and flushing the drain, and checking any condensate pump, is unglamorous work that prevents very expensive water damage.
4. Electrical, defrost, and safety controls tested
Contactors pit, capacitors weaken, and connections loosen with years of vibration. A maintenance visit should inspect wiring and connections, test capacitors and safety controls, and run the system through a defrost cycle to confirm the outdoor unit can clear winter frost on its own. Catching a weak capacitor in October is a small line item; replacing a compressor it took out in January is not.
5. Airflow measured, filters and ducts checked
Low airflow makes a correctly sized heat pump feel undersized: rooms drift, run times stretch, and bills climb. The visit should confirm blower operation, check filter condition, and look for obvious duct leaks or crushed runs in the attic or crawl space — common in Richmond's 1970s and 1980s ranchers. If some rooms never match the rest, our article on uneven heating in Richmond homes walks through the usual causes.
6. Thermostat and settings reviewed
Many efficiency complaints are settings, not equipment. A good visit confirms the thermostat is calibrated, the heating and cooling schedules suit how you actually live, and — for dual-fuel homes — the switchover temperature to backup gas heat is set sensibly. For ductless systems, each indoor head should be run in both heating and cooling, its filter cleaned, and its remote settings checked.
Five minutes a month keeps the professional visits boring.
Check or clean the filter monthly in heavy-use season — ductless head filters rinse clean under a tap and should dry fully before going back. Keep at least 30 centimetres clear around the outdoor unit: trim back garden growth in Broadmoor and Terra Nova yards, sweep leaves off the top grille in fall, and never stack patio furniture or firewood against it. After a storm, glance at the unit for branches or debris. In winter, if snow or ice builds up, clear it gently — never chip at the coil. And keep the area at the base free-draining; standing water around the pad is hard on the unit and common on Richmond's flat lots after heavy rain.
Book fall service in September, spring service in April.
The fall visit prepares the system for heating season: coils cleaned after summer, defrost tested before the first frost, and backup heat confirmed working. The spring visit prepares it for cooling: drain cleared before humidity arrives, refrigerant verified, and cooling performance tested while a repair can still be scheduled calmly. Booking a few weeks ahead of the season matters — the first cold snap and the first heat wave are when every neglected system in the Lower Mainland fails at once and schedules fill. If your system is new, keep the maintenance record tidy: manufacturers can ask for proof of regular service on a warranty claim, and a documented plan protects that coverage.
An older system that needs repairs every season deserves an honest comparison.
Maintenance extends a healthy system's life; it cannot reverse a failing compressor or a coil that leaks every year. If repair bills are stacking up, ask for the replacement math alongside the repair quote.

Common questions
How often should a heat pump be serviced in Richmond, BC?
Twice a year is ideal — once in spring before cooling season and once in fall before heating season — because a heat pump works year-round in both modes. Once a year is the minimum most manufacturers expect, and keeping dated service records helps if you ever make a warranty claim. Homes near the water in Steveston may benefit from the twice-yearly schedule in particular, as outdoor coils collect grime faster.
What does a professional heat pump maintenance visit include?
A proper visit cleans the indoor and outdoor coils, checks refrigerant charge against the manufacturer's specification, clears and tests the condensate drain, inspects electrical connections, capacitors and safety controls, tests the defrost cycle, verifies airflow and filter condition, and reviews thermostat settings. If refrigerant is low, the technician should look for the leak rather than simply topping the system up.
What heat pump maintenance can Richmond homeowners do themselves?
Check or clean the filter monthly during heavy use — ductless filters rinse under a tap and should dry fully first. Keep at least 30 centimetres of clearance around the outdoor unit, clear leaves and debris off the top grille, gently remove snow build-up in winter, and make sure water drains away from the base of the unit rather than pooling around it. Anything involving refrigerant, wiring, or opening the unit belongs to a technician.
What happens if you skip heat pump maintenance?
Efficiency drops first: dirty coils and low airflow make the system run longer for the same comfort, raising electricity bills. Small problems then grow — a weak capacitor can take out a compressor, a blocked drain can cause water damage, and an unnoticed refrigerant leak can leave the system icing up or failing during the first cold snap, when service schedules are busiest.
Does a ductless mini-split need the same maintenance plan?
Yes, with a few differences. Each indoor head has its own washable filter that should be cleaned monthly in heavy-use season, and heads should be run and checked in both heating and cooling modes at each visit. The outdoor unit still needs coil cleaning, refrigerant and electrical checks, and a clear condensate path. Our Richmond ductless cost guide explains the systems themselves in more detail.
When should a Richmond homeowner replace rather than keep maintaining a heat pump?
Consider replacement when repairs are needed every season, the compressor or coil is failing, refrigerant leaks keep returning, or comfort and bills keep worsening despite proper service. Heat pump installation at Airmount starts from $13,000 installed with financing from $100 per month, and up to $21,500 in combined BC rebates may be available when switching off fossil-fuel heat — we will confirm your eligibility at a free in-home assessment.
