Even the most reliable air-conditioning system will let you down if you don’t maintain it.

Here’s how:

  • Check and clean filters monthly.
  • Clear debris and leaves from around the condenser coils
  • Make sure hedges and plants are at least two feet away from the compressor.
  • Check for blockages in the drainpipe.
  • Check insulation around ducts. Bolstering insulation and sealing leaks can help prevent as much as a 40 percent energy loss.
  • Every quarter, bring in a qualified professional to check items like refrigerant and mechanical components.
