Why is My AC Constantly Running?

With a humid and warm Summer ahead of Cape Codder’s, having your AC unit running in tip top shape is extremely important for a comfortable living situation. However, sometimes if your air conditioner is running constantly it can indicate an issue with your unit and put a dent in your wallet if you don’t monitor it.

If you notice that your AC unit is continuously running and not switching to ‘fan mode’ once the room is properly cooled, here are a few things you can look at:

  • This one might be obvious, but it can be overlooked. Make sure your unit is switched ‘fan only’ or ‘fan on’ mode for a little and see if you can tell the difference between when it is set to cool and fan mode so you have a gauge on whether or not it’s running.
  • Try not to set the desired temperature down to a temperature that is too low. Contrary to popular belief, you home will not cool down any faster if you set the temp lower. This will only cause the AC to run longer, resulting in wear and tear.
  • Is your AC too small for you house? It’s possible your last HVAC company mis-judged what size AC and output would be needed. If it’s too small, it will continuously run and run without ever reaching the desired temperature.
  • Have you changed the air vent and filter this month? If you are not changing the filter monthly, it’s possible not enough air is getting through the HVAC system. Taking a much longer time to cool your home.
  • Make sure to check for low refrigerant levels. This is one of the main factors leading to a air conditioner that won’t stop running.
  • Check your air ducts. It may be possible that they are too large and the unit will not be able to distribute air properly throughout the home.
  • Debris such as dust, dirt and pet hair and stop the air flow of the unit as well. To prevent this, try to clean the condenser coils of the air conditioner.
  • Make sure to set upmaintenance from a professional HVAC specialist at least twice a year. That way you will know if there are any underlying issues and to keep your unit in top-notch shape.
