Why Does My AC Keep Turning On and Off (or Suddenly Stop)?: A The ColonyHomeowner's Guide

This topic comes up regularly across The Colony, from Lake Lewisville to the rest of Denton County. Here's what's worth knowing if you're local.

For The Colony Homeowners

The Colony, zoned to Lewisville ISD, sits along Lake Lewisville with a mostly established housing stock built out over the past few decades. Lake-adjacent humidity is a real factor here, worth accounting for during any cooling diagnostic or maintenance visit.

The Colony FAQ

Can a bad thermostat really cause short cycling?+

Yes. A thermostat that's misreading room temperature, whether due to poor placement or an internal fault, can call for the system to shut off prematurely, before the room has actually reached the set temperature, then call for it to run again shortly after.

Is it safe to keep running a system that shuts off suddenly and restarts on its own?+

It depends on the cause. If it's happening repeatedly, it's worth having diagnosed rather than continuing to let it cycle, since the underlying issue, whatever it is, isn't resolving itself and may be causing additional wear each time it happens.

Is this guide relevant for The Colony homes in Denton County?+

Yes, this applies to homes throughout Denton County, including The Colony. If you'd like this looked at for your specific address, call (817) 935-8540 and mention your ZIP code.
