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

Granbury sits in Hood County, and homeowners here, including those near the Granbury downtown square, run into this exact topic regularly. Here's how we walk through it.

For Granbury Homeowners

Granbury ISD covers a wide mix of home styles and ages in Granbury, and that variety is part of why we treat every visit as its own diagnostic rather than assuming what we'll find based on the neighborhood.

Granbury, the Hood County seat, is built around the historic Granbury downtown square and Lake Granbury, with a mix of decades-old homes near downtown and newer construction and lake homes on the city's edges. Lake-adjacent humidity is a real factor for homes near the water, tending to push cooling systems harder through the summer.

Granbury 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 Granbury homes in Hood County?+
