The Problem of AC Short Cycling

AC short cycling occurs when your system shuts on and off rapidly. It’s a relatively common issue, but it’s also a problem that can affect how long your system lasts and how well it performs. Here’s what you need to know about AC short cycling and when to call for professional HVAC repair in Houston.

Malfunctioning Thermostats

A broken thermostat can often be the cause of short cycling. Thermostats that can’t accurately read the temperature in a room will cause your HVAC system to go haywire. However, it doesn’t have to be broken to act like this.

Thermostats in precarious places, like those in direct sunlight or by a drafty window, might signal the AC to turn on and off prematurely. This can often be an easy fix or mitigated by investing in a new smart thermostat.

Clogged Filters

One of the easiest ways to address short cycling without needing HVAC repair in Houston is to switch out your filter. A dirty or clogged filter can force your system to work harder. This, in turn, makes it overheat and turn off prematurely. Homeowners should clean or change their filters regularly to avoid this issue.

Low Refrigerant Levels

Refrigerant is necessary for your HVAC system to cool off your home adequately. Without it, your system won’t be able to maintain the temperature you set it to, making it more likely to cycle on and off.

This is often a much more involved issue and could be due to a leak somewhere in the unit. You should have a certified HVAC technician check on your system if you suspect low refrigerant levels might be part of the problem.

Oversized Units

Sometimes, short cycling can happen if a unit is too large for the space it’s cooling. These systems will often reach their temperatures much faster, causing them to shut on and off more frequently.

This issue doesn’t always have an easy fix since it could involve replacing your system. However, having a professional confirm that this is the issue is recommended before making that decision.
