The air filter is the simplest, cheapest part of your cooling system — and neglecting it causes more AC problems than almost anything else. CANRO Heating & Cooling has cooled Greater Vancouver homes since 1999. Call (604) 359-1081 or request a free, no-obligation quote.
A clogged filter starves your AC of airflow, which cuts cooling, freezes coils, strains the blower and drives up bills. Replacing it on schedule is the one bit of maintenance every homeowner can — and should — do.

📞 (604) 359-1081Request a free quoteStandard air-conditioning (cooling only) generally does not qualify for BC’s big efficiency rebates — those reward systems that also heat. The good news: a heat pump cools your home in summer and heats it in winter, and it does qualify. If rebates matter to you, ask us to quote a heat pump alongside the AC — the incentives often make the higher-performing system the cheaper choice over time.

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 cooling system 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.
