5 Reasons Your Air Conditioner is Constantly Running
If your air conditioner rarely or never turns off, it means your unit is working harder than it should to keep your home cool. The HVAC technicians at Montgomery Heating & Aire in Mountain Home, Arkansas, say this is an indication that your unit is not functioning properly. It is important to diagnose the problem early to prevent it from causing further damage to your unit.
Here are five reasons your air conditioner is running continuously: 
1. You Need to Replace Your Air Filter
Most AC filters need to be changed every 90 days and more often if you have pets. If you have neglected to change your air conditioning filter for a while, it could reduce the amount of cold air your unit is able to circulate through your house.
2. Your Thermostat Is Not Working
If your air conditioner cools your home effectively but still runs constantly, your thermostat may be the culprit. It is possible for your thermostat to incorrectly measure the temperature in your home.
3. Poor Insulation
Another potential problem could be poor insulation. If your home is not insulated well, it will leak the cool air through the walls or roof and force your unit to work harder to compensate.
4. Your Unit or Ductwork Is Improperly Sized
If the problem does not stem from your filter, thermostat, or insulation, your HVAC system might be improperly sized. If a unit is too small, it will have to work overtime to cool your home, and incorrect ductwork will not circulate air effectively.
5. Your Unit Has Reached the End of Its Life
As a general rule of thumb, an air conditioner has a life cycle of 10 years. If your unit is approaching or has already passed the decade mark, you should consider upgrading to a newer, more energy-efficient model.
