If the simple checks above don’t solve it — or anything involves refrigerant, electrical parts, the compressor, motors, coils or a breaker that keeps tripping — it’s time for a licensed technician. Call (604) 359-1081 or book online. We offer same-day diagnostics during cooling season when our schedule allows.
Please stay safe. Don’t open the indoor or outdoor unit, touch the contactor, capacitor or wiring, add or “top up” refrigerant, reset a breaker that keeps tripping, or pour anything into the system. Refrigerant, electrical and compressor work must be done by a licensed, refrigerant-certified technician. The safe homeowner steps are simple: check the thermostat is set to cool, replace a dirty filter, make sure the outdoor unit is clear of leaves and debris, and confirm the breaker is on. If that doesn’t fix it, stop and call (604) 359-1081.
Modern cooling equipment is sealed, pressurized and wired to be serviced by trained professionals — not opened up at home. Refrigerant is handled only by technicians certified to do so; releasing it is unsafe and illegal, and an incorrect charge will quietly wreck efficiency and shorten the compressor’s life. Capacitors hold a dangerous charge even with the power off, and a wiring or breaker mistake on your air conditioner is a real shock and fire risk. A licensed CANRO technician diagnoses the true root cause, repairs it to code, keeps your manufacturer warranty intact, and leaves the system safe — the first time. If a part is dangerous or sized wrong, we tell you honestly.

Mould or mildew on the coil or in the condensate drain. A professional coil and drain cleaning removes it — filter changes alone won’t.
Turn it off at the breaker immediately and call us. A burning or electrical smell means overheating wiring or a motor — a fire risk that needs urgent attention.
Mould and bacteria smells can affect air quality, especially for allergies or asthma. A professional cleaning and fresh filters resolve it.
