The saying, “anything that can go wrong, will go wrong”, may not be so far-fetched when it comes to AC units, which seem to exclusively malfunction or break down when temperatures are on the rise. It is not uncommon for people to only notice their home AC malfunctioning during the summer months when the unit is operating full-time.

  • Check for a dirty air filter

    • The filter may be dirty or clogged and need replacing
  • Check your thermostat settings

    • If warm or hot air is coming from the vents, make sure the thermostats are set to COOL and not HEAT
  • Check your air conditioner circuit breakers.

    • On your main electrical panel, check for any circuit breakers that may be in the OFF position. If your circuit breakers are clearly labeled, look specifically for one labeled “air conditioner” or “AC”.
  • Check your outdoor unit

    • A dirty outdoor unit can lead to many malfunctions, from higher-than-normal energy bills, to warm air as opposed to cool air, and can become the cause of frequent repairs.
  • Check all air vents as many AC problems are caused by closed/blocked air vents, if you notice any of the following:

  • AC struggling to cool your home
  • Ice on refrigerant lines or a frozen evaporator coil
  • Water leakage from your AC
  • Blower motor issues
  • Duct leakage 
  • Higher energy bills

Make sure that all supply vents, in your home, are open and not blocked, by furniture, rugs, or drapes. Be sure to check vents in your home’s unused rooms as well.

If once you’ve gone through these steps, your AC unit is still malfunctioning, it most likely needs servicing. An AC unit breakdown, during a hot spell, can pose a risk to your health and that of your family.
