Farmers Branch 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.
