Why Your AC's Evaporator Coil Freezes Up (and What to Do About It): A KellerHomeowner's Guide

Keller homeowners ask us about this often, whether they're closer to Keller ISD or elsewhere in Keller ISD. Here's the same honest breakdown we give customers in person.

For Keller Homeowners

We service homes throughout Keller, from those near Keller Town Center to neighborhoods further out, and this topic comes up regularly regardless of which part of Keller ISD a home falls in. The fundamentals don't change by zip code, but knowing the local housing stock helps us know what to expect before we even arrive.

Keller, home to its own Keller ISD, has grown substantially over the past two decades, with newer subdivisions surrounding Keller Town Center and Bear Creek Park alongside older, more established neighborhoods. Newer homes here still benefit from a proper Manual J load calculation if a system is ever replaced, since a lot of production-built subdivisions were sized on assumptions rather than an actual calculation.

Keller FAQ

How long does it take for a frozen coil to thaw?+

It varies by how much ice has built up, but running the fan-only setting (not cooling mode) typically thaws a coil within a few hours. Turning the whole system off overnight is also a reasonable, safe approach if you're not in immediate need of cooling.

Will the coil just freeze again after it thaws?+

If the underlying cause, a dirty filter, low refrigerant, or restricted airflow, isn't addressed, yes, it's very likely to freeze again. Thawing it is a temporary fix, not a solution, which is why the actual cause needs to be diagnosed rather than just repeating the thaw cycle.

Is this guide relevant for Keller homes in Tarrant County?+
