Why Is Your Air Conditioner Running Constantly?

Why Is Your Air Conditioner Running Constantly?


During the sweltering Phoenix summer, it’s typical for your air conditioner to run longer than usual. However, if the weather isn’t particularly hot or if your air conditioner is working nonstop and failing to keep your house cool, there may be an issue that is worth looking into.

There are various reasons why your AC system may seem to be running non-stop. Some of the causes can point to a system issue, while others might make you aware of additional problems in your house that you need to address.


Below are some common explanations for why an air conditioner might seem like it’s always running:

  • Dirty Evaporator Coil: Before turning it on for the summer, did you neglect to have your air conditioner serviced in Chester this spring? If so, there may be dirt and debris on the evaporator coil, which would hinder cooling and make the unit work harder to cool your room. If the unit is in a place where it accumulates a lot of grime, such as close to a restaurant kitchen, this can happen even after it was cleaned a few months ago.
  • Clogged Air Filter: The air flow is hindered when your system’s air filter is full of dirt and debris, which can make it difficult for your air conditioner to operate. The system runs when it shouldn’t since it can’t remove humidity and chills the air to the desired temperature without enough air passing over the coils.
  • Low Refrigerant Charge: Your unit cannot cool the space if there is insufficient refrigerant in the system, most likely as a result of a leak in the coils. When this occurs, the device will continue to operate while exerting more effort. To locate the leak, fix it, and replenish the refrigerant to the proper level in this situation, you’ll need the help of our expert HVAC service technician.
  • Faulty Thermostat: If your thermostat is malfunctioning, it won’t know when the desired temperature has been reached and won’t switch off. If the room’s actual temperature is lower than the set point, check your thermostat. There is a significant likelihood that the thermostat will need to be replaced if it is.
  • Leaky Ducts: You may be losing cold air through duct leaks, especially if your building has older ducting. The insulation may not be present or the joints may not be sealed. If enough cool air is lost, the temperature in your space won’t rise above the predetermined level, and the system will continue to operate.
  • Dirty or Blocked Condenser: Your outdoor unit’s condenser coils require cleaning just like the evaporator coils on the inside, if not more so because they are exposed to the weather. Airborne dirt and debris can obstruct airflow, as can a build-up of leaves or even nests of animals or insects. This issue will be resolved by a thorough cleaning with products and equipment from a competent company.
  • Your AC unit is too large for your home and is short-cycling: You most certainly have a short-cycling issue if your air conditioner runs for short intervals and the air in your home seems stuffy. A/C units that are too big for your house won’t be able to effectively remove humidity, and they typically shut off too early, causing hot and cold spots throughout the house.
  • Your AC System is Overdue for Maintenance: The cooling process might be hampered by dust accumulation in places like the condenser coil and evaporator coil. As a result, your AC has to work harder and longer than necessary to reach the temperature you want. Your system needs a maintenance appointment if it hasn’t had any in more than a year.
  • Your AC Unit is too Small to Cool Your Home Effectively: The summer months will be difficult for your air conditioner if it doesn’t have adequate tonnage (cooling capacity) for the particular size, design, and temperature issues of your home. To try to reach the desired temperature on your thermostat, it can run continuously. Continuously operating at full power places needless strain on the system and risks overheating or premature component wear.
  • Air Leaks or Poor Insulation – Time to Seal: Another common reason for an unrelenting and inefficient operation of your unit is poor sealing or inadequate insulation. You can be losing the valuable cold air you need in the summer if your house is not tightly sealed while your air conditioner is running through tiny holes or uninsulated walls or roof. Your home might never reach the temperature you want if you are losing the cold air in this way, which will make the air conditioner operate longer than necessary.
