Question:
Our air conditioner kept us cool last summer but it is getting older. What can we do to help it get through another summer?
Much of the routing maintenance for an A/C system can be performed by a homeowner. Here are some tips.
- Outside (condensing) unit: Make sure the unit is not covered with debris, bushes, leaves, etc. – cut back vegetation if too close.
- Disconnect power to unit and clean the cooling fins. This can be done with a water hose – never use high pressure sprayers or brush to clean. Note: chemicals can be purchased to clean dirty fins but use caution in selecting cleaner – may be best to have a pro do.
- Change your return air filter. This should be done at least every three months and in many cases monthly, depending on factors such as having pets in the house. If the filter is very dirty and caked with dust, have the internal coil checked and cleaned by a pro – especially if the filter is collapsed and air is bypassing it.
- Make sure the condensation drain line is not blocked by grass, debris or soil at the exterior and clean drain line from the indoor A/C unit to the exterior. This can be done by pouring a couple of cups of bleach and water or a specialized cleaner into the drain line clean-out stand pipes at the indoor unit. If these are not present, access to unit is limited, i.e., in the attic or if you are unsure how to do this, call an HVAC tech.
