When it’s hot outside, your home’s air conditioner really gets a workout. Keeping the AC on helps you maintain a comfortable interior temperature, but this comes at a cost.

That is why it is so important for you to make sure your system is running properly. If you discover your AC system is running constantly, then it may be driving your energy costs up. At this point, you need to find the underlying issue.

Do You Need Help? There are several reasons that your home’s AC system may be running nonstop during the summer months. It doesn’t always indicate a problem. Some of the situations that may indicate there is a problem with your system can be found here.

Size of the AC Unit

When your air conditioner is the proper size, it will run fairly continuously to maintain the desired, constant temperature in your home. These systems are going to operate at their highest efficiency level when they can do their job “full tilt.”

If the unit is too small, it will have to work harder to keep your home cool. Also, you will never be able to achieve the desired temperature in your home, even though the system is running often. You are probably going to encounter a number of breakdowns, as well.

If the unit is too big, it won’t be able to effectively remove the moisture present in your home’s air. This can create an output of clammy, moist air. The system is actually going to have shorter run times and use more electricity, which will cause higher energy costs.

The Thermostat Doesn’t Work

If you notice that your system is never shutting off, then there may be a problem with the thermostat. It could be that your home has reached the set temperature but the thermostat isn’t registering the conditions inside the home. In this situation, the AC is going to keep running.

You can check the thermostat by placing another thermometer close to it. After a few hours, look at the reading. If it is close to the set temperature, then there may be an issue with the home’s thermostat.

Poor Insulation or Air Leaks

Insufficient insulation and poor sealing are also culprits that can result in a unit running inefficiently and constantly. If your home isn’t closed up tightly while your AC system is on, you are likely losing the cooled air through small holes or the roof or walls that aren’t insulated.

If this happens, you are never going to be able to reach the desired temperature. This causes the AC unit to run much more than necessary. Insulating and sealing your home may be necessary to improve unit efficiency.

The Bottom Line

As you can see, there are more than a few reasons that your AC system may run continuously during the summer months. If you can’t figure out what the underlying cause is, then it is best to call the professionals for an inspection. They can get to the underlying issue and ensure it is fixed and efficiency is restored.
