You want your AC running when you need it. There’s nothing worse than expecting it to be running and walking into a hot house.
Yet, you could also face a different problem where your AC unit is constantly running. It likely means there’s a problem unless it’s blistering hot outside. You won’t like your electric bill if you don’t get a fix.
So, what’s a possible cause for an AC running constantly? Read on for a few things to check out if your AC is always on.
Check for the Simple Causes
When your AC is always on, it’s easy to assume the worst and start to prepare yourself for a costly repair.
You might be surprised how often the cause is something simple that’s easily remedied.
Your AC might be running because there is a door ajar or a window open. This is letting warm air in, which is causing the AC to stay on.
You may have the wrong settings on your thermostat. It could also be the blower fan, not the actual running AC unit.
Dirty Air Filter
Your central air conditioner has a filter. One reason it might be running continuously is that the filter is dirty.
When the filter is dirty, air can’t properly circulate. The dirty filter restricts the airflow coming out of the unit.
In turn, that means the AC unit isn’t cooling in your home as well. Once your home isn’t getting cool, the AC unit will run continuously.
Start by changing to a new filter and see if that helps with airflow.
Another reason your AC won’t turn off might be related to the thermostat.
Your thermostat is the brain of the operation, telling your AC unit when to run to get the house to a specific temperature.
Check your thermostat to ensure you have the settings where you intend. Try turning the temperature up to see if the AC unit turns off.
It could be something as simple as your thermostat needing new batteries.
You might need a new thermostat if those two options don’t impact the AC running.
Evaporator Coil Issues
The evaporator coils in your AC unit are located inside the unit. They are essentially part of the AC unit that cools the warm air from your home.
If you have a constantly running AC, it might be because these evaporator coils are dirty, and the AC unit is working harder to try to cool the air.
These coils are fragile, so you may want to call a professional to clean them.
Wrong Size Unit for the House
If none of these options address the running AC unit, it might be time to consider the air conditioner size.
If your AC unit is too small, or surprisingly too large, to handle cooling in your home, it can cause it to run more.
Get a Fix for the AC Running Constantly
Your AC running constantly might not mean your house is getting any cooler. It could mean your AC is working hard to cool the house with little success. The only result is a higher electric bill.
