Why Is My AC Running But Not Blowing Cold Air?

Your AC is running but not cooling because of issues like a clogged air filter, low refrigerant, frozen evaporator coils, drainage blockages, or faulty fans/blowers. In Mountain View, CA, we routinely repair these exact problems, including refrigerant leaks, drain line blockages, capacitor and contactor failures, and evaporator coil replacements.

Quick checks:

• Replace a dirty filter.
• Ensure indoor and outdoor vents are clear.
• Turn system off for 2–3 hours if coils are iced, then restart cooling.
