When your air conditioner stops performing on the hottest day of an Okanagan summer, you need it fixed fast. Macdonald Mechanical provides professional AC repair and seasonal maintenance for all brands across Kelowna, West Kelowna, Lake Country, Peachland, Summerland, Penticton, Vernon, and the surrounding Okanagan — keeping your home cool and comfortable all summer long.
Don't wait for a complete breakdown. These are the warning signs that your AC needs a professional look before the problem gets worse:
If your AC is running but your home isn't reaching the set temperature, the issue could be low refrigerant, a dirty coil, or a failing compressor.
Ice forming on your indoor or outdoor unit is a sign of restricted airflow or low refrigerant. Turn the system off and book an appointment — running a frozen unit can cause serious compressor damage.
Water around your indoor air handler usually means a blocked condensate drain line. Left untreated, this can cause water damage to your home.
Grinding, squealing, rattling, or banging sounds indicate a mechanical problem — worn bearings, a loose component, or debris in the unit.
If your electricity costs have spiked without a change in usage, your AC may be losing efficiency due to dirty coils, low refrigerant, or a failing component.
A unit that won't start could point to a tripped breaker, a faulty thermostat, a failed capacitor, or an electrical issue — all of which we can diagnose and repair.
The best time to have your air conditioner serviced is in the spring, before the cooling season begins. A seasonal tune-up ensures your system is ready to handle the Okanagan's hot summers without issue, and gives us the chance to identify any problems before they leave you without cooling on the hottest days of the year.
A professional AC tune-up typically includes:
Stay ahead of repairs and keep your AC running at peak efficiency year after year. Macdonald Mechanical offers maintenance plans so your system gets the attention it needs every season — without you having to remember to book it. Contact us to find out what plan works best for your home.
Contact Us About a Maintenance PlanWhether your AC was installed by us or another company, we can service it. Macdonald Mechanical services all major air conditioner and mini-split brands across the Okanagan — no exceptions.
Older air conditioners — particularly those over 12–15 years old — often reach a point where repairs are no longer the most cost-effective option. If your unit is aging and requiring repeated fixes, we will give you an honest assessment of whether a repair or replacement makes more financial sense.
If you're also considering your home's heating needs, a heat pump may be worth exploring — it provides efficient cooling in summer and heating in winter, all in one system, and currently qualifies for significant CleanBC rebates that a standalone AC does not.
We repair and service air conditioners throughout the Okanagan. If you are unsure whether we serve your area, give us a call.
There are several common causes: a dirty air filter restricting airflow, low refrigerant due to a leak, a frozen evaporator coil, or a failing compressor. A professional diagnosis is the best way to identify the root cause and get it fixed correctly.
We recommend an annual tune-up in the spring before the cooling season begins. Regular maintenance keeps your AC running efficiently, extends its lifespan, and helps catch small issues before they become costly repairs or a midsummer breakdown.
Yes. Macdonald Mechanical services all major air conditioner brands, regardless of where the unit was purchased or installed.
Ice on your AC unit is usually caused by restricted airflow — often a dirty filter — or low refrigerant levels. Turn the unit off and let it thaw, then check your filter. If the problem persists, book a service appointment as running a frozen unit can damage the compressor.
