Duncanville 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 there anything specific to Duncanville homes I should know before calling?+

Nothing that changes the fundamentals, just let us know you're in Duncanville and what you're seeing, and we'll take it from there with the same honest diagnostic we bring to every call.
