Getting Your Air Conditioning Ready Before Summer

Air conditioning systems tend to reveal their problems on the first truly hot day, when everyone else is calling for help too. Checking your system in spring gives you time to arrange any work before demand peaks.

Simple checks you can do yourself

• Replace or clean the filter. A clogged filter reduces airflow and makes the system work harder.
• Clear around the outdoor unit. Remove leaves, branches and debris, and keep plants trimmed back so air can flow freely.
• Check the thermostat. Replace batteries if it uses them, and make sure it switches the system on when you lower the temperature.
• Run the system for a while. Listen for unusual noises and check that cool air is coming from the vents.
• Look at the condensate drain. Water pooling near the indoor unit can signal a blocked drain line.

Signs it is time to call a professional

• The system runs but the air is not cool.
• It turns on and off frequently.
• You notice ice on the refrigerant lines or the outdoor unit.
• There are grinding, banging or squealing noises.
• Your energy bills have risen without an obvious reason.

Safety first

Always switch off power to the system before cleaning around it, and leave electrical and refrigerant work to a qualified professional.

If your system needs attention, you can request quotes for HVAC service from local businesses.
