Why Won’t My AC Run Consistently?

technician-in-doorwayLiving in Arizona means that your air conditioner is just as crucial as the roof over your head, and that means that you really cannot afford to ignore any signs of trouble with your air conditioning system. This includes if your air conditioner seems to function decently when it is running, but the system is simply not running reliably. Why might this happen? Well, there are a few different reasons why your AC may not be running consistently, as is generally the case with air conditioning problems of any kind.

While some potential causes of the problem may be resolved by the homeowner his or herself, others are going to require professional AC repairs in Tempe, AZ. If this is the case, then remember that you can always turn to Goettl Air Conditioning Phoenix in your time of need. Not only will we diagnose the problem accurately, but we will resolve it completely. So read on, and be sure to contact us if there is no obvious solution to the problem.

And Yes, It Is a Problem

The situation in which an air conditioner starts up, but then runs only briefly and then cycles back down actually has a name: short cycling.  Short cycling is problematic for a few reasons. First of all, it places a whole lot of unnecessary strain on your air conditioning system: strain that could wind up causing damages over time.

It also wastes a lot of money, too. When your air conditioner starts up, it uses a lot more energy than it would to simply keep running. That is going to be reflected in your energy bills. Resolving the root cause of the problem protects your system, your comfort, and your budget.

So What Causes Short Cycling?

There are a few different problems that may be at play. First of all, you may simply have a very dirty air filter. If this is the case, you can simply change that filter on your own in order to resolve the problem. A dirty filter can create so much airflow resistance that the system shuts down in order to protect itself.

You may also have a refrigerant leak, which is a major problem as your system is designed to work with a specific amount of refrigerant. Not only does a low charge lead your system to work harder and potentially overheat, but it can also cause the evaporator coil to ice up. That insulates the coil, making the system work even harder to cool your home, exacerbating the problem.

Issues with individual components could also be to blame. Your thermostat may simply be reading temperatures incorrectly, causing it to shut the system down before it should. Or, you could have a faulty run capacitor, which is a component that maintains a steady charge to keep the system running reliably. Whatever the case may be, this is definitely not the type of problem that you want to let fester. Contact us when your system won’t stay running (despite having a clean filter in place!).

G-O-E-T-T-L it’ll keep you cool but it’s hard to spell.
