AC Running Constantly in Rowlett, TX? Here’s Why

Is It Normal for an AC to Run a Lot in September?

It sure is…as it’s plenty warm in Texas right now. But, is your AC system running more than usual?

Your air conditioner naturally runs longer when outdoor temperatures are high, especially during the hottest part of the afternoon. Your home’s insulation, thermostat setting, amount of direct sunlight and even how often exterior doors are opened can affect run times. What you want to watch for is a change in behavior. If your AC previously kept the house comfortable but now runs almost continuously without reaching the thermostat setting, it’s worth investigating.

Why Your AC May Be Running Constantly

Several problems can cause an air conditioner to work longer than it should.

A dirty air filter: Restricted airflow forces the system to work harder to move conditioned air through your home.
Dirty condenser coils: The outdoor unit has spent the summer collecting dirt, grass clippings, cottonwood and other debris that can interfere with heat transfer.
Low refrigerant: A refrigerant leak can reduce cooling capacity and cause extremely long cycles.
A struggling capacitor or motor: Electrical components take a beating during a long Texas cooling season.
Ductwork problems: Leaking or poorly insulated ducts can dump cooled air into an attic before it ever reaches your rooms.
An aging AC system: Older equipment can gradually lose its ability to keep up with the cooling demands of your home.

Pay Attention to the Air Coming From Your Vents

Here’s a simple test homeowners can perform without taking anything apart. When your AC is running, put your hand near a supply vent. The air should feel noticeably cooler than the room. If airflow seems weak or the air isn’t particularly cool, your system may need professional attention. Also pay attention to whether some rooms are significantly warmer than others. Uneven cooling can indicate airflow, ductwork or equipment problems.

Don’t Ignore a Problem Just Because Fall Is Coming

It’s tempting to think, “I’ll deal with it next year.” Rowlett can still experience plenty of warm weather after summer officially ends. More importantly, a problem that develops at the end of cooling season isn’t necessarily going to disappear while the system sits idle.

Finding the issue now can prevent an unpleasant surprise on the first hot day next spring.

Could a Constantly Running AC Raise My Electric Bill?

Absolutely. Longer run times mean more electricity consumption. If your electric bill remains unusually high even as temperatures begin to moderate, your HVAC system may be using more energy than necessary. A professional inspection can determine whether the issue is maintenance-related, a repair problem or simply the result of an older system losing efficiency.

Frequently Asked Questions

Should my AC still be running in September in Rowlett?

Yes. Warm weather commonly continues well into September in North Texas, so regular AC operation is completely normal.

Is it bad for an AC to run continuously?

Long cycles can be normal during very hot weather, but an AC that rarely shuts off or can’t reach the thermostat setting may have an airflow, refrigerant, mechanical or efficiency problem.
