A Short Cycling AC Is a Big Problem

An air conditioner that keeps switching itself on and off is short cycling. And while short cycling is annoying, it’s more than just a frustration — it’s a big problem for your AC unit. Short cycling occurs for a few reasons, and as it puts a huge strain on your air conditioner, it can shorten your unit’s life span considerably. 

What Causes AC Short Cycling?

An air conditioner should cycle every 15 to 20 minutes, about three times per hour. If it’s really hot outside, your unit can cycle more frequently, and it will do the same if the thermostat is set way below the current indoor temperature. It does this to maintain a constant cool temperature, which you need in sunny California. 

When an AC is stuck in the cycle of starting up, it will turn on and off constantly without completing a proper cooling cycle. The most common problems that cause AC short cycling include: 

Incorrectly Sized AC Units

When you buy a new AC unit, it is imperative that it is the right size for the space. An AC that is too large will be unable to run a complete cycle or remove the humidity from the air. The AC needs to run for 20 to 30 minutes to cool efficiently and dehumidify. An AC that is too large needs to be replaced with the correct sized unit. 

Electrical Problems

Short cycling can be caused by loose wires or corroded electrical connections. A heat pump with loose wires can lose power for a short time, then switch back on again, and continue this process repeatedly. Schedule an air conditioning repair in Concord, CA, to have the loose wiring fixed.

Thermostat Malfunction

A miscalibrated thermostat will be unable to read the inside temperature correctly and will cycle on and off. Unfortunately, a malfunctioning thermostat will need replacing. 

Low Refrigerant Levels

Low levels of refrigerant will cause your AC to overheat and switch itself on and off. Similarly, an overcharged AC will leak refrigerant into the compressor and cause the system to switch on and off.
