To ensure your home AC is running efficiently and maintains its manufacturer warranty, we recommend performing monthly maintenance on your home AC (especially during the hot summer periods). Regular maintenance usually involves cleaning or replacing the AC filters. For example, you can remove the return air filter on a ducted unit or lift the front of a split system unit, take out the filter and clean it with a hose.
If the air conditioner is in constant use, the house quickly builds up dust, or if you have pets, you may need to do this more frequently. It’s important to note that some ducted AC systems will need a licensed technician with the correct tools and knowledge.
