Every time your air conditioner starts up, it should run for a while minutes before turning off again. The entire process is called a cooling cycle, and it’s vital to how your HVAC system generates comfortable indoor temperatures. So if you’ve noticed your AC keeps turning off, comfort can be harder to maintain.
There are several reasons why your air conditioner keeps shutting off, but one of the most common reasons is short cycling. This irritating HVAC problem involves cooling cycles that aren’t long enough to make effective use of your air conditioner. It may keep switching off before your home has a chance to cool down. We’ll review a few details of what short cycling is and where it comes from. Then, we’ll share a few more separate reasons your cooling equipment keeps shutting down.
When an air conditioner short cycles, it shuts off before reaching the set temperature. It may not be long before the thermostat realizes this and instructs the AC to start up again. But since there’s a problem, the air conditioner will continue to short cycle. This may extend the time required to cool your home while putting extra strain on important components. If left alone too long, short cycling could even lead to premature system failure.
Another frustrating part of short cycling is the number of potential causes. In general, a lot of short-cycling issues can be traced back to overheating. But the excess heat could just be the symptom of another unknown issue. During air conditioner repair, a technician will look for a few of the most common things to start narrowing down the root cause.
Short cycling is a complicated problem ideal for the tools and knowledge of a professional technician. But there are still other reasons your air conditioner may be shutting off unexpectedly. Let’s take a look.
Electrical Malfunction: Any number of malfunctions with the wiring or an electrical switch could lead to constant shutdowns. Maybe the wiring is old or damaged, but electrical problems may need professional care for a prompt, safe solution.
Compressor Failure: This important component applies pressure to force heat out of the refrigerant before it’s expelled from your home. When the component fails, a safety switch will recognize the pressure change and tell the air conditioner to shut off.
Refrigerant Leak: Your refrigerant absorbs and releases heat, making it one of the most important parts in your HVAC system. A leak can be catastrophic, as the coils designed to hold the coolant are expensive to replace. It’s important to move quickly if you suspect a leak to avoid premature air conditioning replacement.
Clogged Condensate Line: When humidity is condensed into moisture during the cooling process, the condensate line safely drains it away. When the line or drain pan is clogged up, a float switch shuts off the AC before half of it is running underwater.
