Common AC Problems
What Real Deal HVAC checks during diagnosis.
Real Deal HVAC explains what is happening and gives you the practical next step.
AC Not Turning On
The diagnostic can include electrical checks, thermostat signals, breaker symptoms, contactors, capacitors, and fan operation.
Weak Airflow
Airflow issues can involve dirty filters, dirty coils, blower concerns, duct restrictions, or frozen coil symptoms.
Frozen Coil
A frozen AC coil can be linked to airflow restriction, filter/coil condition, blower problems, or refrigerant-performance concerns.
Leaks and Drain Lines
Water around the system can point to condensate drain, pan, frozen coil, or installation/airflow concerns.
Repair vs Replacement
Older systems with major failures, repeat breakdowns, poor comfort, or high repair costs may be better candidates for replacement.

Why is my AC blowing warm air?
Warm air can come from thermostat settings, airflow restrictions, dirty coils, electrical issues, fan problems, compressor concerns, or refrigerant-performance issues.

How quickly can you come out for AC repair?

What should I check before calling an HVAC technician?
Check thermostat settings, batteries if applicable, the air filter, breaker, outdoor unit airflow, and whether supply vents are open. If the coil is frozen or the system is leaking, call for diagnosis.
Can a frozen AC coil be repaired?
Often, but the cause must be diagnosed. Frozen coils can involve airflow restrictions, dirty filters or coils, blower problems, or refrigerant-performance concerns.
