Signs Your AC Needs Attention
Warm air blowing
AC is running but not cooling. Could be low refrigerant, a failing compressor, or restricted airflow.
Weak airflow
Air comes out but barely. Likely a duct issue, clogged filter, or failing blower motor.
Unusual noises
Grinding, squealing, or clicking from the outdoor unit. Something mechanical needs attention.
Water leaks
Condensation pooling around the indoor unit. Drain line may be clogged or the evaporator coil is frozen.
Short cycling
System turns on and off rapidly. Could be an electrical issue, thermostat problem, or oversized unit.
High electric bills
If cooling costs jumped without a usage change, your system is losing efficiency.
Bad odors
Musty smell means mold in ductwork. Burning smell means an electrical problem. Call us for either.

Don't Put Up With the Miserable Summer Heat
AC Questions? We Have Answers.
Why is my AC blowing warm air?
Several possible causes — low refrigerant levels, a dirty condenser coil, a failing compressor, or a thermostat issue. Our technicians will diagnose the root cause and fix it. Don't keep running a system that's blowing warm — it wastes energy and can cause further damage.
How can I improve my AC's efficiency?
Change your filter every 1-3 months, keep the outdoor unit clear of debris, and schedule annual maintenance. A tune-up catches small issues before they become expensive repairs and keeps your system running at peak efficiency — which means lower electric bills.
Do you install ductless mini-splits?
Yes. Ductless mini-split systems are great for homes without existing ductwork, room additions, or areas where you need independent temperature control. We install, repair, and maintain all major mini-split brands.
