Frequently Asked Questions

Why is my central AC running but not cooling?
Most common causes: low refrigerant, dirty condenser coil, failed capacitor, dirty evaporator coil, or refrigerant leak. We diagnose the specific cause and repair it.
My AC runs constantly but doesn't cool below 78°F. Why?
This is often low refrigerant, a dirty coil, or a system that's undersized for your home. We'll diagnose the cause and advise on repair or replacement.
Can I check anything before calling?
Replace or clean your air filter, check that no vents are blocked, and clear any debris from around the outdoor unit. If the problem persists, call us.
