AC Not Cooling at All? Utah Diagnostic Guide — what Farmington homeowners should know
AC running but the house won't cool below 78°F on a 90°F day usually means one of four things: airflow is restricted, refrigerant is low, the system is undersized for the load, or the compressor is failing. Walk through the diagnostic in order — most homeowners can identify the cause in 15 minutes.

Most likely causes in Farmington
Restricted airflow (filter, coil, or blower)
A 50%+ blocked filter or blanketed condenser coil cuts cooling capacity by 25–35%. The system is doing its best with reduced airflow.
Most commonLow refrigerant from a leak
20% low on refrigerant = roughly 35% loss of cooling capacity. Symptoms: cold suction line at outdoor unit, possibly ice on it.
CommonOversized or short-cycling AC
An oversized AC cools the air near the thermostat fast, hits setpoint in 4–6 minutes, and shuts off. Bedrooms at the end of duct runs never get cooled. Feels like 'AC not cooling' even though the unit is running.
CommonFailing compressor
Compressor that's pulling normal amps but not pumping refrigerant pressure correctly. System runs, blower runs, outdoor fan runs, but lineset isn't actually cold.

How long should it take my AC to cool the house?
A properly-sized AC should drop indoor temp by ~1°F per 30–45 minutes on a 90°F day. Faster than that and it's likely oversized; slower and it may be undersized or have airflow/refrigerant issues. Time it on a hot day for a baseline.
Should I run the fan continuously or on auto?
Auto saves energy and lets the coil dry between cycles (less mold risk). Fan-on improves whole-house mixing — useful in homes with one thermostat and uneven temps, but uses 250W extra. We default to AUTO for most installs.
