Is Your A/C Acting Up? Here Are Some Basic Troubleshooting Tips


Has your home’s central air conditioning system been acting up? Perhaps it’s not cooling your home as quickly as it used to, or appears to be running constantly. Or maybe your monthly electric bills seem noticeably higher than last year’s, even though you haven’t otherwise changed your energy use at home. You can call a trusted A/C technician to look at your system, but before taking that step, try some A/C troubleshooting tips.

A/C Troubleshooting Tips

  • Check the air filter. A clogged filter can explain both decreased performance and increased energy use. When the filter is clean, it allows for smooth airflow through the A/C evaporator coil and the home’s ductwork system. When it’s dirty, your air conditioner has to work harder and longer to deliver the same amount of cool air. This wastes energy and stresses parts, leading to more repairs. Check the filter today, and then put your filter inspections on a monthly schedule. Change the filter when it looks clogged or dirty.
  • Clear debris away from the outside condenser/compressor. This unit also requires smooth airflow to allow for optimum heat exchange between the refrigerant in the coil and the outside air. Dirty coils, both inside and outside, also will impede heat exchange, though cleaning the coils is best left to a trained A/C technician.
  • Make sure the condensate drain isn’t clogged. The water – which is condensed out of the cooling air during the A/C process – can back up and damage walls, floors, fixtures and belongings. It also can promote mold and mildew growth.
  • Schedule annual preventative maintenance for your central A/C. This may not fit in with the other A/C troubleshooting tips, but it’s probably the most important. For your cooling system to run with its intended efficiency, and provide the comfort your family expects, it requires professional maintenance annually. During the tune-up, all of the other troubleshooting steps can be addressed as well.
