Every time your air conditioner turns on, it should run for a while minutes before turning off again. The complete process is called a cooling cycle, and it’s key to how your HVAC system provides comfortable indoor temperatures. So if you’ve noticed your AC keeps turning off, comfort can be harder to maintain.
There are many reasons why your air conditioner keeps shutting off, but one of the most common culprits 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 check out a few details of what short cycling is and where it starts. Then, we’ll provide a few more separate reasons your cooling equipment keeps shutting down.
Your Air Conditioner Could Be Short Cycling
When an air conditioner short cycles, it turns off before reaching the set temperature. It may not be long before the thermostat recognizes 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 necessary to cool your home while placing extra strain on important components. If left alone too long, short cycling can even lead to premature system failure.
5 Problems That Could Lead to Your Air Conditioner Short Cycling
Another annoying aspect of short cycling is the number of possible causes. In general, a lot of short-cycling issues can be caused by 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.
- Overheating: Too much heat can ruin components inside your air conditioner. Safety features should detect overheating and shut the AC off to protect key parts. But if the original problem hasn’t been addressed, this process just starts over again.
- Poor Airflow: Your HVAC system requires enough airflow to function at safe, optimal temperatures. When the air filter or ductwork is clogged, poor circulation could47] lead to overheating, which means short cycling.
- Wrong AC Sizing: HVAC equipment should be correctly “sized” for your home. This means that the power of your air conditioner matches the cooling needs of your home. An air conditioning system that’s too large will pump out cool air too fast, tricking the system into shutting off early before the entire house is cooled down.
- Dirty Condenser Coils: This component expels the heat collected from inside your home. When the coils are too dirty, this heat could end up in the air conditioner. The high levels of heat may be enough to result in a premature shutdown.
- Thermostat location: The thermostat should be in a central location away from a vent or the HVAC equipment itself. This ensures every room of the house has cooling for long enough to reach the set temperature. Putting your thermostat too close to cool air can trick it into thinking the temperature has been reached earlier.
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.
A Few Other Reasons Your AC Keeps Switching Off
Electrical Malfunction: Any number of malfunctions with the wiring or an electrical switch might lead to constant shutdowns. Maybe the wiring is old or damaged, but electrical problems should receive professional care for a prompt, safe solution.
Compressor Failure: This crucial component applies pressure to force heat out of the refrigerant before it’s vented out from your home. When the component fails, a safety switch should recognize the pressure change and direct the air conditioner to shut off.
Refrigerant Leak: Your refrigerant holds and releases heat, making it one of the most important substances 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 prevent 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 stops the AC before half of it is running underwater.
