Each time your air conditioner turns on, it should run for several minutes before turning off again. The entire process is known as 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 tougher to maintain.
There are different reasons why your air conditioner keeps turning off, but one of the most common culprits is short cycling. This aggravating 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 comes from. Then, we’ll provide a few more separate reasons your cooling equipment keeps turning off.
Your Air Conditioner May Be Short Cycling
When an air conditioner short cycles, it shuts off before reaching the desired temperature. It may not be long before the thermostat recognizes this and instructs the AC to turn on again. But since there’s a problem, the air conditioner will continue to short cycle. This will extend the time needed to cool your home while putting extra strain on key components. If left alone too long, short cycling may even lead to premature system failure.
5 Problems That May Lead to Your Air Conditioner Short Cycling
Another annoying part 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 check 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 will often 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 steady airflow to work at safe, optimal temperatures. When the air filter or ductwork is clogged, the lack of circulation can47] 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 suits the cooling needs of your home. An air conditioning system that’s too large will dump cool air too fast, tricking the system into switching off early before the entire house is cooled down.
- Dirty Condenser Coils: This component dissipates the heat collected from inside your home. When the coils are too dirty, this heat may end up in the air conditioner. The high levels of heat might be enough to trigger a premature shutdown.
- Thermostat location: The thermostat should be in a convenient location away from a vent or the HVAC equipment itself. This ensures each room of the house has cooling for long enough to reach the set temperature. Installing 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 Turning Off
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 should receive professional care for a prompt, safe solution.
Compressor Failure: This important component uses pressure to force heat out of the refrigerant before it’s removed from your home. When the component fails, a safety switch will 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 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 respond 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.
