SIGNS YOUR AC NEEDS REPAIR
More than just a cooling issue? Problems like weak airflow or persistent odors can sometimes point to issues within your ductwork or filtration. If a repair doesn’t solve the problem, our Indoor Air Quality Solutions can help you breathe easier and improve your home’s overall comfort.
Warm Air
Your AC is blowing warm air instead of cool, which usually means a refrigerant issue, compressor problem, or blocked airflow.
Weak or No Airflow
Reduced airflow from vents can indicate a failing blower motor, clogged filters, or duct obstructions.
AC Constantly Running
If your system never shuts off, it may be struggling to reach the set temperature due to low refrigerant, thermostat issues, or mechanical problems.
Strange Noises
Banging, squealing, or rattling sounds are signs of loose parts, worn-out components, or motor issues.
Water Leaks
Water pooling around your unit or dripping from vents usually signals a clogged condensate drain or frozen coils.
Frozen Coils
Ice buildup on coils reduces efficiency and may indicate airflow issues, low refrigerant, or mechanical faults.
Outdoor Unit Not Turning On
If your condenser won’t start, there could be electrical issues, a faulty capacitor, or a compressor failure.
