If your new home came with a central air-conditioner installed, you may find the following information helpful. However, for detailed maintenance tips you should refer to the manufacturer’s instructions that accompany the unit.
- The thermostat must be set lower than the room temperature to operate the system. However, it is not recommended that the temperature be set lower than 21˚C, as this can lead to the freezing of the coil and condenser unit.
- Most air-conditioning systems are designed to cool the house to a temperature 10˚C lower than the outside temperature (e.g. if the outside temperature is 35˚C, do not expect the inside temperature to go much lower than 25˚C).
- The cooling system should have an annual inspection (much the same as the furnace).
- Change and/or clean the air filter on a regular basis.
- The cooling system will operate more efficiently if it is left to run all summer. As the outside weather changes, the inside temperature should be adjusted by raising or lowering the thermostat setting, rather than by turning the unit off and on. If the system is shut down, it could take several hours before the temperature and humidity level is lowered back down to an acceptable level.
In addition to the installation of an air-conditioner, you may wish to consider installing a humidifier or an electronic air cleaner in your home.
PLEASE NOTE THAT THE WARRANTY ON THE COOLING SYSTEM WILL BE VOIDED SHOULD A CONTRACTOR OTHER THAN THE ORIGINAL INSTALLER OF YOUR COOLING SYSTEM MAKE MODIFICATIONS OR ADDITIONS TO THE SYSTEM.
