Why does my AC stop and start again? With the Phoenix summer about to get into full swing, the last thing you want to be dealing with is AC short cycling. However, before you can fix the issue, you’ll need to determine what’s causing it.

Read on as we explore a few common reasons behind your AC’s short cycling and how opting for professional AC services in Phoenix, AZ, can help.

The Dangers of Short Cycling

As frustrating as it can be, missing out on consistent cool air isn’t the worst thing about short cycling. Your AC going on and off in rapid succession will also leave you with higher electric bills. This is because short cycling consumes significantly more power.

If this wasn’t bad enough, it also strains your unit, leading to more serious repairs down the line.

Why Does Your AC Keep Turning On and Off?

Want to know what’s causing short cycling in your AC unit? Here are a few common culprits.

1. Issues With Your Thermostat

Sometimes, your AC turning on and off can be the result of a malfunctioning thermostat. Your thermostat could be incorrectly reading the temperature of your Phoenix home. When this happens, it’ll be unable to relay the proper information to your AC unit.

2. Dirty Air Filter

When you’ve got a dirty air filter, AC problems are never far away. This is because your air filters play a vital role in maintaining proper airflow. Dirty filters can cause your AC unit to struggle.

The more your air conditioner fights to get air where it needs to go, the more it’ll start switching on and off in short, rapid bursts.

3. Dirty Coils

If you’re still wondering, “Why does my AC stop and start again?” you could be dealing with a dirty or frozen evaporator coil.

When too much dust, dirt, and other debris clog your AC’s coil, it can easily prompt your air conditioner to turn on and off. In extreme cases, a clogged coil could cause the unit to break down entirely.

4. Refrigerant Leak

Leaking refrigerant is another possible culprit. This is because when your AC unit detects that it’s running low on coolant, it will shut off to prevent possible damage, such as AC capacitor failure. This causes the AC compressor to short-cycle.

5. Compressor Failure

Speaking of the compressor, your air conditioner turning on and off can sometimes be a telltale sign that its compressor is experiencing an issue. The compressor could be overheating or malfunctioning, preventing your AC unit from running as it should.

6. Electrical Problems

Issues with your AC unit could have nothing to do with the unit itself, but rather with your Phoenix home. If you are certain there is nothing wrong with your air conditioner, but it continues to turn on and off, your home may have faulty wiring.

7. Oversized Unit

On some occasions, the problem could be the result of installing an AC unit that’s too big for your home. This is especially the case if the problem began shortly after you installed the unit.

Getting a Certified AC Repair Company in Phoenix To Diagnose the Issue

The last thing you want to do is incorrectly diagnose the issue. Sadly, given all the possible causes, determining the root cause of your AC’s short cycling is easier said than done. The good news is that there is an ideal solution: hiring a certified HVAC technician.

So, the next time you start asking yourself, “Why does my AC stop and start again?” reaching out to a professional will get you the right answer and solution.
