Why is Your A/C System Short Cycling? 

Jul 20

You wake up in the middle of the night, drenched in sweat. The A/C system that was keeping you cool all day has now turned into your own personal sauna. You check the thermostat, and it says that it’s still set at a comfortable temperature.

Now, what's wrong with your air conditioner? One possibility is that your cooling system is short cycling. What causes your equipment to turn on and off frequently? Read on!

Top Reasons Why Your Air Conditioner is Short Cycling 

Everything happens for a reason, and your A/C unit is no different. When it switches on and off a couple of times a day, it’s trying to tell you something!

Here are the most common causes of short cycling and what you can do about them:

Dirt Buildup in the Filter
This is by far the most frequent cause of an A/C unit that short cycles. A clogged or dirty filter will restrict airflow, causing your system to work overtime. When your unit runs more often than it should, it will cause it to overheat and turn off until it cools down again.

The solution is to check your filter monthly and clean or replace it as needed. You should also be sure that you’re using the right type and size of filter for your air conditioner. If nothing changes after you’ve cleaned or replaced the filter, call the pros for immediate A/C Repair Fairfield, CA. 

Frozen Evaporator Coil
What if the filter is clean, but your unit is still short cycling? It could be that the evaporator coil is frozen. A frozen coil will cause your system to turn off because it can’t properly circulate air.

The good news is that this problem is usually easy to fix. But if you do not have the experience and the tools, it will be challenging, and hiring a technician with a proven track record in A/C repair Fairfield, CA is the best way to go.

Oversized Air Conditioner
Many homeowners automatically think that the larger the A/C system, the better. But that's not always the case. If your unit is too big for your home, it will cool the air too fast and cause it to turn on and off frequently. What's worse is that it won’t remove humidity from the air.

The best way to deal with this problem is to consider things like the size of your home, the number of windows, and the insulation when you’re buying a new unit. If you need help sizing your air conditioner, don’t hesitate to ask your A/C repair Fairfield, CA contractor for assistance.

What Can You Do to Bring Your Unit Back in Its Good Shape? 

 Now that you know what’s causing your system to short cycle, you're probably wondering what you can do to bring it back to its top condition. Worry not. Here are some tips you can follow:

  • Check and Clean the Condenser Coil. The condenser coil is located outside and can get dirty over time. When it does, it will cause your system to work harder and shorten its lifespan. To clean it, simply turn off the power, remove any debris, and hose it down.

  • Upgrade Your Thermostat. An old or outdated thermostat can cause your system to turn on and off frequently. If you have an older model, consider upgrading to a new, energy-efficient thermostat.

  • Get a Tune-Up.  Professional A/C repair Fairfield, CA contractors recommend that you have your system tuned up at least once a year. This will ensure that it’s running efficiently and catch any potential problems before they become expensive repairs.
