Frozen AC Coil: What It Means and How to Fix It — what Layton homeowners should know
Ice on an AC coil is never normal. It means warm air isn't crossing the coil fast enough OR the refrigerant pressure is too low — either way, the coil drops below freezing, condensate freezes, and now you have a block of ice instead of a heat exchanger. Running the unit while frozen damages the compressor. Here's the safe diagnostic + thaw.
Local note for Layton: at 4,356 ft elevation, HVAC equipment loses roughly 17% of nameplate capacity. Issues that would be minor at sea level can become symptoms here — we factor elevation into every diagnostic.
Most likely causes in Layton
Severely clogged air filter
The most common cause. A loaded filter starves the coil of airflow; coil temp drops below 32°F; condensate freezes; ice grows; airflow stops entirely.
Most commonClosed or blocked supply registers
Closing too many registers (people often try to redirect cooling to one room) raises static pressure on the air handler. The blower can't move enough air across the coil. Same result as a clogged filter.
CommonLow refrigerant
Refrigerant pressure that's too low drops the coil saturation temperature below 32°F even with normal airflow. Ice forms at the inlet U-bend first. This is a leak — refrigerant doesn't get used up.
CommonFailing blower motor or capacitor
Indoor blower running slow or intermittently produces the same effect as low airflow. Listen for unusual humming or short-cycling at startup.

How fast can you get to Layton for frozen ac coil: what it means and how to fix it?
Same-day on most weekday calls — typical 2-hour arrival window across Layton and the rest of Davis County. After-hours (after 7 PM) is a flat $150 emergency dispatch, waived on approved repair. Layton is well inside our standard service area.
Do you charge to come out to Layton for frozen ac coil: what it means and how to fix it?
$79 HVAC diagnostic (waived on approved repair). If you approve the repair on the visit, the diagnostic fee is waived — so the diagnostic isn't an extra charge on top of the fix.
Can I just chip the ice off?
Don't. Aluminum fins bend instantly — you'll permanently restrict airflow and cause it to re-freeze even after the underlying cause is fixed. Patient fan-only thawing is the only safe method.
How long does the AC need to be off after a freeze?
Until the coil is fully thawed AND the condensate pan is dry. Typically 4–6 hours of fan-only running. Then we recommend a 30-minute warm-up before resuming cooling so any moisture in the coil drains.
