Troubleshooting Common AC Problems We Fix
AC Blowing Warm Air
If your vents are pushing out lukewarm air, you likely have a refrigerant leak or a frozen evaporator coil. We use advanced leak detectors to find the source, seal it, and recharge your system with R-410A refrigerant to restore icy-cold airflow.
Loud Grinding or Squealing Noises
An air conditioner shouldn't sound like a freight train. Grinding often indicates a failing fan motor bearing, while squealing usually points to a loose belt or compressor issue. Call us immediately to prevent permanent motor failure.
System Short-Cycling
If your AC runs for 5 minutes and shuts off, it’s "short-cycling." This kills efficiency and is often caused by an oversized unit, a clogged air filter, or a failing thermostat sensor. We calibrate your system to run full, efficient cooling cycles.

The True Cost of Skipping Maintenance
Homeowners who neglect regular maintenance typically spend far more on energy costs, emergency repairs, and premature replacements than the modest cost of preventive care. Dirty coils, clogged filters, and worn components force cooling systems to work much harder while providing less cooling, dramatically increasing energy bills throughout the summer season.
Emergency repairs during peak cooling season often cost significantly more than the same repairs performed during routine maintenance visits, while system failures leave families without cooling during the most uncomfortable weather when alternative cooling options are limited and expensive.
