If your AC isn't cooling in Salt Lake City, start with the thermostat, filter, and breaker. Look for ice on the lines or a stopped outdoor unit. If basic checks don't restore cooling, a local licensed HVAC contractor can diagnose the system.
Start with the easy checks
Before assuming the worst, walk through a few simple items. In Salt Lake City homes, many "no cooling" calls turn out to be a setting, a filter, or a tripped breaker.
- Thermostat set to cool and below the room temperature
- Air filter clean enough to see light through
- Breaker for the AC has not tripped
- Vents in main rooms are open and unblocked
Check the outdoor unit
Step outside and look at the condenser. It should be running when the system calls for cooling. Clear away leaves, grass, or debris. Listen for unusual noises.
Watch for a frozen coil
If you see ice on the refrigerant lines or indoor coil, the system has frozen up. Restricted airflow or low refrigerant are common causes. Turn the system off and let it thaw. Running a frozen AC can cause more damage.
Refrigerant and ductwork
Refrigerant is a sealed system. Low refrigerant typically means there's a leak that needs a licensed technician. Ductwork issues — disconnected runs, leaks, or weak design — can leave certain rooms warm even when the system is working.
Salt Lake City context
Many Salt Lake City homeowners only learn about an AC issue at the first hot stretch of the year, after the system has been idle through cold weather.
When to stop troubleshooting
If you've checked the basics and the system still isn't cooling, it's time to call a local licensed HVAC contractor. Running a struggling AC during warm weather can compound the problem.
