1. Clean or Replace the Air Filter
• A clogged filter reduces airflow and efficiency.
• Replace it every 1-3 months, especially before heavy summer use.
2. Inspect and Clean the Outdoor Unit
• Remove debris, leaves, and dirt from around the condenser unit.
• Use a hose to gently clean the coils.
3. Check the Thermostat
• Test your thermostat to ensure it’s functioning properly.
• Consider upgrading to a programmable or smart thermostat for better efficiency.
1. AC Blowing Warm Air
Causes:
• Dirty air filter
• Low refrigerant levels
• Thermostat settings incorrect
• Frozen evaporator coil
What to Do:
• Check and replace the air filter.
• Ensure the thermostat is set to “cool” and the correct temperature.
• If refrigerant is low, call an HVAC technician (a leak might be the issue). (972) 322-7560
• If the evaporator coil is frozen, turn off the unit to let it thaw and check for airflow issues.
2. AC Not Turning On
Causes:
• Tripped circuit breaker
• Faulty thermostat
• Blown capacitor or motor issue
What to Do:
• Check and reset the circuit breaker.
• Replace thermostat batteries or check if it’s working.
• If the unit still won’t turn on, call an HVAC professional (it could be a capacitor or electrical issue). (972) 322-7560
