If your air conditioner keeps turning on and off, and on, and off, it can be, well, annoying. But, what you might not know, is that in addition to being annoying, an air conditioner that starts and stops rather frequently can actually be quite a BIG deal.
It’s called short-cycling, and it is definitely not something you want to ignore. Firstly, it’ll place all sorts of wear and tear on the system itself. Secondly, it’ll put quite a large hole in your wallet. Unfortunately, many homeowners don’t quite understand why short-cycling happens in the first place, so below, we’ve explained it all for you. All you’ve got to do is keep reading to find out more. (Oh, and of course, call us for all things HVAC in Carrollton, GA!)
What Is Short-Cycling?
Short-cycling is a term used to describe when there is something within the system that prevents it from completing a full cooling cycle. To put it simply, when your system is short-cycling, you will notice that it turns on and off every few minutes, making it impossible to keep your home cool. Not only does this lead to sky-high energy bills, but it also can leave you with the cost of some pretty hefty repairs.
Why Does It Happen?
There are a number of issues that can lead to short-cycling:
- A clogged air filter: Your air conditioner filter collects dirt and debris as air flows passes through it. However, if this filter is not changed on a regular basis, it can become too clogged, which restricts airflow in and out of the system. When hot air becomes trapped in the system, the AC will shut down as a safety measure, and when it cools off it will kick back on only to start the process all over again. Therefore, we recommend changing out the air filter every 1 to 3 months during the summer season.
- Frozen evaporator coils: The compressor is the part of the system responsible for pushing refrigerant gas through the air conditioner after it’s been evaporated in the evaporator coil. The compressor also helps keep the rhythm of the AC so that it can consistently move heat out of the home. If the compressor becomes damaged by frozen coils, it can start to malfunction, throwing off the rhythm of the AC.
- The AC is too large: If you’ve had an oversized AC unit installed in your home, chances are that it will begin to short cycle. Since an oversized unit produces too much cooling output, your home will reach it’s desired temperature much before the AC has had a chance to complete a full cooling cycle. The best thing you can do is to replace your oversized air conditioner with a unit appropriately sized for your home.
- Refrigerant leaks: Low refrigerant levels will force your air conditioner to work much harder than normal, which can result in short cycling. Therefore, it is important to be on the lookout for signs of a refrigerant leak. These include low cooling output, liquid around the system, and strange hissing sounds.
