Ever noticed your air conditioner running endlessly and wondered if that’s normal? During Scottsdale’s hot summers, it’s easy to assume that a constantly running AC is just working hard to keep you cool.
But here’s the truth: your air conditioner shouldn’t run nonstop. If it does, there might be something wrong that needs your attention.
What’s A Normal Cycle Time?
Under typical conditions, your AC should run in cycles lasting around 15 to 20 minutes. That’s long enough to cool your home efficiently and remove humidity before shutting off for a short rest.
During extreme heat, cycles may last a bit longer, but if your unit runs for 30 minutes or more without a break, that’s usually a red flag.
Why Your AC Might Be Running Too Long
The Unit Might Be Undersized
If your AC is too small for your home, it will struggle to meet your cooling demands. The result? Longer cycles, higher energy bills, and unnecessary strain on the system.
Dirty Coils Or Filters
Dust and debris on the condenser or evaporator coils can prevent efficient heat exchange, making your unit work harder and longer. The same goes for dirty air filters that restrict airflow. A quick cleaning or replacement can make a big difference.
Thermostat Problems
Sometimes the issue is as simple as thermostat settings. If your thermostat is set too low or placed near a heat source, it may misread the temperature and cause the AC to run longer than needed.
Air Leaks Or Poor Insulation
Cool air escaping through leaks in your ductwork or poorly sealed windows means your AC has to work overtime to maintain a steady temperature. Checking insulation and sealing leaks can help restore normal cycle times.
What Happens If It Runs Too Long?
When your AC runs constantly, it’s not just about wasted energy. Extended run times can cause parts like the compressor or fan motor to wear out faster. Plus, your energy bills will start climbing.
On the other hand, cycles that are too short (called short cycling) are just as bad. That usually means your unit is oversized or has a mechanical issue. Short cycling prevents your system from properly dehumidifying your home, leaving the air cool but clammy.
Keep Your AC In Top Shape
Your air conditioner should cool efficiently, not endlessly. Keeping up with maintenance and getting timely inspections can prevent long run times and extend your system’s life.
