Air conditioning maintenance checklist
Carry out these basic checks and cleans every month during the cooling season to improve the chances of your A/C system running smoothly.
Change the filter
Dirty filters reduce performance by up to 15% and increase energy costs. If you don’t change your filter for a long period, this could cause serious damage to the evaporator and other components. Aim to clean or replace your filter every month when the system’s in use. If your house has a lot of dust or you have pets who shed fur, you may need to change the filter more frequently.
Clean the coils
Filters prevent most dust and dirt from getting into the system, but some will still get through over time. This impairs the efficiency of the evaporator and condenser coils, as they can’t absorb as much heat. These coils should be cleaned once a year, ideally by a professional, or more often if they’re exposed to dust and dirt in their surroundings.
Check the coil fins
Dirt can also collect on the aluminium fins on evaporator and condenser coils over time. The fins can also move or get bent out of shape. They should be cleaned and moved back into their original position to restore normal performance.
Outdoor condenser units should be kept free from dirt, dust and foliage. Sweep away leaves and other debris and cut grass, bushes and other plants back to at least one metre, to make sure airflow isn’t restricted. These units are designed to be outdoors in all weather conditions, so they should never be covered.
Give it a test drive
Don’t wait until the summer to check that your system’s working properly. Switch it on in the spring and let it run for an hour, so you’ll have the chance to spot anything unusual that needs to be dealt with before the heat arrives.
Getting your units checked out by the professionals saves you money in the long term. When your air conditioner’s operating at peak efficiency, you’ll enjoy lower electricity bills and the components will last longer, so you won’t have to replace the system before its time.
