3 Reasons Phoenix Air Conditioner Short-Cycling Occurs

By // 2016.04.19

Phoenix Air Conditioner Short-CyclingIs your Phoenix air conditioner turning off after only a short period of time? Are you possibly experiencing short off-times with your air conditioning unit? These are both examples of a common issue called short-cycling. Not only does this waste energy, the constant switches between on and off are terrible for the continued quality of your air conditioner.

There are many possible explanations as to why your AC unit is running but is not consistent, a.k.a. “short-cycling.” Luckily, there are many possible fixes to your Phoenix air conditioner short-cycling problem—you simply first need to determine what the cause is.

Refrigerant Leak in AC Unit 

One possible reason for your air conditioner to be short-cycling is that there is a refrigerant leak somewhere in your AC unit. A Band-Aid fix to this problem would be, of course, to keep adding refrigerant. However, this would simply be a short-term fix as you’d have to keep purchasing and adding refrigerant as your unit continues to leak; this would end up being a very costly solution in the long run.

Instead, contact an experienced Phoenix air conditioner repair company to locate and fix your refrigerant leak to ensure the longevity of your unit.

Thermostat Malfunction in AC Unit

Your AC unit short-cycling may be thanks to a faulty thermostat; perhaps your thermostat is not doing its job by failing to tell the unit the proper times to turn off and on. While it is possible this is an AC thermostat malfunction—it is reading temperatures incorrectly and thus in need of replacement—this issue could also be due to the positioning of the thermostat within your home. Placing it underneath a draft or in direct sunlight will undoubtedly affect its ability to read temperatures correctly.

If an issue with the thermostat is the case, your air conditioner repair specialist will be able to quickly determine whether it needs to be replaced or simply moved.

Oversized AC Unit

Lastly, a simple cause for your AC unit short-cycling may be that your unit is simply too big for the room it’s meant to cool. An easy way to tell if this is the root of your problem is to think back to how long your unit has been short-cycling. Have on or off cycles been less than five minutes since you first installed the unit? If so, it’s entirely possible that you’re using a unit that is too big.

There are plenty of online resources to help determine whether your AC unit is the proper size for your space, but your best bet is still to have a repairman come examine the unit in person. They can also be of assistance if you need to install a smaller unit.

AC unit repairs can become costly, but they will be even more so if they’re put off for the future. If you are experiencing air conditioner short-cycling, don’t wait to contact a Phoenix-area specialist. It will both save you money in the long run and get your home’s climate back under control.
