Every time your air conditioner starts up, it should run for several minutes before shutting down again. The complete process is called a cooling cycle, and it’s important to how your HVAC system maintains 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 switching 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 efficient use of your air conditioner. It may keep shutting 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 offer 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 switches off before reaching the desired 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 can extend the time needed to cool your home while putting extra strain on key components. If left alone too long, short cycling might even lead to premature equipment failure.
5 Problems That Could Lead to Your Air Conditioner Short Cycling
Another annoying part of short cycling is the number of potential 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: Excessive 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 steady airflow to run 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 properly “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 big will dump cool air too quickly, 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 get 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 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. Placing 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 is shutting off unexpectedly. Let’s take a look.
A Few Other Reasons Your AC Keeps Shutting Off
Electrical Malfunction: Any number of malfunctions with the wiring or an electrical switch can 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 vital 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 respond 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 stops the AC before half of it is running underwater.
