When Roanoke temperatures soar into the 90s with high humidity, your air conditioner is probably running longer than normal to keep up. At W.C. Butler Heating and Air Conditioning, we’ve seen how often AC systems can fail in the summer or show signs of losing efficiency. Longer cooling cycles are normal, but nonstop operation can strain your system and make it harder to cool down. Here’s what to know about your AC and what to do if it’s working overtime.
Is It Normal for My AC to Run Constantly?
Many homeowners assume their AC should cycle off and on every few minutes, no matter what’s going on with the weather, but that’s not always the case. A system that’s properly sized for your home can run longer periods when outdoor temperatures are extreme.
The longer run times also help maintain a steady indoor temperature while removing humidity more effectively, but only if the temperature reaches the setting on your thermostat. Systems that run all day without reaching the set temperature need an AC check-up.
A Dirty Air Filter Can Restrict Airflow
One of the most common causes of an AC that won’t stop running is a clogged filter. Once the filter is restricted with dirt, grime, and dust, it restricts airflow and makes it harder for your system to move cooled air throughout your home. Replacing your AC filter regularly helps improve efficiency, airflow through the system, and protects system components.
Ductwork Issues Could Make Cooling Less Effective
Many homeowners focus on their AC equipment but overlook the ductwork that carries the cool, conditioned air through your house. If your ducts have dust buildup, debris, leaks, or restricted airflow, it will eventually reduce system performance while circulating more airborne particles throughout your home. Professional duct cleaning or sealing can improve airflow and also help with allergies.
Hidden Air Leaks Can Keep Your AC Running
Heated attic air on the hottest days in Roanoke can get pulled into your home and through tiny gaps around recessed lighting, attic access panels, plumbing penetrations, and ceiling fixtures. Your windows may be closed, but these small openings are continuously introducing heat that your AC has to work harder to remove.
Low Refrigerant Can Prevent Your AC From Cooling
Your AC can still run for a while with refrigerant leaks, worn components, or a failing capacitor. At some point, you’ll start noticing warm air coming from the vents, uneven temperatures between different rooms in your house, or rising electric bills. These issues won’t go away on their own and need prompt AC repair before they turn into larger problems.
Keep Your Home Cool This Summer
The longer your AC struggles, the harder it has to work to keep your home cool and comfortable. Whether the problem is a clogged filter, dirty ductwork, a refrigerant leak, or another issue, prompt service can restore your comfort before a small repair turns into a costly breakdown.
