What Causes AC Units To Run Constantly?

A few common problems can cause your home’s central AC to run constantly, and these problems typically fall into five categories. They include:

 

AC Unit Is Improperly Sized

For maximum efficiency, a central AC unit must be fitted accordingly to the size of the home. An AC unit that’s too small or too large will cause issues with uneven cooling, inefficiency or rising electricity costs.

 

  • Is the Unit Too Small? A unit that’s too small must work harder and longer to cool the home. This increases the wear and tear on the unit, which will shorten the unit’s life. Additionally, this can cause costs to rise, due to the added runtime necessary to cool the home.
  • Is the Unit Too Large? An AC unit that’s too large will run for shorter periods of time. Yet, this is a problem, because the unit will not run long enough to remove moisture from the air. As a result, the home will have damp, clammy air. Additionally, because it runs for shorter periods, it turns off and on more, and as a result, wear and tear do occur more quickly.

 

Your AC Requires Maintenance

Irregular maintenance is one of the most common causes of AC inefficiency. It’s recommended that you have the unit serviced twice per year – once in spring, and before winter. Regular maintenance ensures the coils, ducts, and air filters are clean, which maximizes airflow and cooling power. A few common maintenance issues include:

 

  • Dirty condenser
  • Clogged or restricted air filters
  • Low refrigerant charge
  • Dirty evaporator coils

Thermostat Problems

Your home’s thermostat tells the AC unit the current temperature in the home. When the thermostat is faulty and does not properly register the current temperature, your AC will likely run longer or stop running too soon. The result is typically an unevenly cooled home.

 

You can test your thermostat by placing a thermometer nearby. After an hour or so, the temperature readouts should be very close. If not, you likely need to have the thermostat replaced. Additionally, the connection may have come loose, which can also cause your AC unit to over-run.

 

Leaking Ductwork

Insulation and well-sealed ductwork contribute to the efficiency of your AC unit. A home that’s drafty, or that has old, improperly sealed ductwork will “leak” cool air out. As a result, the AC has to work harder to compensate. Properly insulated windows, ductwork, and attic spaces can all improve the efficiency of your HVAC unit.

 

AC Unit Is Too Old

Finally, when AC units reach the end of their lifespan, they become much less efficient. As a result, they have to work harder and longer to cool the home, resulting in increased runtimes and ballooning electricity costs. Replacing your home’s AC unit with an energy-efficient model will reduce runtime and can help to keep your home more evenly cooled.
