Lancaster calls on this topic aren't unusual for us, especially from homes near the Lancaster downtown square. Here's the short version of what we'd tell you on-site.

Lancaster, home to its own Lancaster ISD, mixes a historic downtown square with newer residential growth on the city's edges. We treat every home here with the same upfront pricing and honest diagnostics we bring to every job.

Lancaster 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 Lancaster homes I should know before calling?+

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