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

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