To verify proper operation
Every 1-3 months
- Replace air filter regularly based on manufacturer’s recommendation.
- Turn on system only when outside air temperature is greater than 60 degrees Fahrenheit.
- Set thermostat to desired temperature or to a temperature slightly higher than normal if away from home during the day. This will allow for quicker cooling to your desired temperature at night rather than trying to cool a hot house.
- If air conditioner does not operate, check thermostat is set to “COOL” setting. If that doesn’t help, check the circuit breakers.
- There are two: one that controls the compressor and one that controls the fan. Verify that both are in the “ON” position.
- If either is tripped, switch it to the “OFF” position then to the “ON” position.
- If that doesn’t work, call a qualified HVAC contractor for assistance as necessary.
- If the system is operating properly, ensure that the condensation drain tube is draining water and is unobstructed. This is usually a clear plastic tube located next to the heat pump which drains into a floor drain or to the outside.
- Verify that the outside compressor unit operates free and clear of any debris.
- Remove any protective cover left on the unit over the winter.
- Consider installing ceiling fans where desirable. They help with air circulation and enable the system to operate more efficiently.
- Reduce sunlight entering your home during the hottest parts of the day.
- Make sure all cooling and return air vents are clean, clear, and unobstructed.
- Set air vent vanes upward on lower floors and slightly downward on upper floors.
- Air blowing from the vents should be noticeably cool. If not, there may be a refrigerant leak somewhere. Consult with a qualified HVAC contractor as necessary.
