The hvac vent is not blowing

Frequently asked questions

Do I need air conditioning in Vancouver?
Vancouver summers have been getting hotter — the 2021 heat dome saw temperatures over 40°C. Most modern Vancouver homes now install a heat pump that provides both heating and cooling, replacing a furnace and avoiding the need for a separate A/C system.
How much does central A/C cost in Vancouver?
A typical 2.5–3 ton central air conditioner added to an existing forced-air furnace costs $5,500–$9,500 installed. A heat pump conversion (cooling + heating in one unit) is usually a smarter long-term investment given available rebates.
How often should A/C be serviced?
Annual servicing in spring keeps the outdoor coil clean, refrigerant charge correct, and the indoor evaporator coil and condensate drain clear. Skipping service is the single biggest cause of premature compressor failure.
