Best Humidity Setting for Heat Pump in Vancouver Summer

Recommended Humidity Range
The ideal indoor humidity for Vancouver summer is 40-50%. Below 35% feels dry. Above 55% feels sticky and can promote mould growth. Vancouver summer outdoor humidity often exceeds 70%, so active dehumidification is needed.
Using Dry Mode
Dry mode on your heat pump prioritizes humidity removal over cooling. The fan runs at low speed and the compressor cycles to maximize condensation on the coil. Use dry mode when the home feels humid but the temperature is comfortable (22-25°C). Dry mode uses less energy than full cooling.
Tips for Better Dehumidification
Keep the thermostat fan setting on AUTO (not ON) — continuous fan operation re-evaporates moisture from the coil. Use a higher thermostat setting (24-25°C) with a dehumidistat if available. Ensure the condensate drain is flowing freely. Clean the air filter monthly — a dirty filter restricts airflow and reduces dehumidification.
