- 📍 Irvine-Based — Serving Costa Mesa Daily
A lot of Costa Mesa's housing went up in the 1960s and 70s — Mesa Verde, Eastside, Westside, Mesa del Mar — and much of it runs cooling systems well into their second or third decade. That's when capacitors fail, coils clog, and refrigerant circuits start leaking. Alpha & Omega repairs air conditioners across Costa Mesa and the South Coast Metro area, usually the same day, from our Irvine base. Call (310) 600-8152.
AC Problems We Fix in Costa Mesa
- AC running but not cooling — dirty condenser coils, failed capacitors, refrigerant leaks, frozen evaporator coils. While you wait, read why an AC blows warm air.
- AC won't turn on at all — thermostats, breakers, float switches, contactors; our step-by-step guide covers the free checks you can do first.
- Ice on the unit or lines — a frozen AC means an airflow or refrigerant problem; see why an AC freezes up.
- Water leaking from the AC — clogged condensate drains and pans; see why an AC leaks water.
- Weak airflow or short-cycling — clogged filters, blower and capacitor failures, a system starting and stopping every few minutes.
- Loud outdoor unit — failing fan motors and compressors caught early cost far less than caught late.
Rentals, Landlords, and Property Managers
Costa Mesa has one of the highest shares of rental housing in Orange County, and we handle those calls smoothly: tenants can book the visit, landlords or property managers approve the work by phone, and everyone gets an itemized invoice with photos of what failed. No games — just a documented, honest repair.
Refrigerant Work Done Right
Handling refrigerant is EPA-regulated: our technicians are EPA Section 608 Universal certified. If your system is low, something is leaking — simply topping it off wastes money and vents refrigerant, so we locate and fix the leak first. That's the honest way, and it's also the EPA-compliant way.
Stop the Next Breakdown Before It Starts
Most emergency AC calls we run in Costa Mesa were preventable: a coil cleaning here, a capacitor test there. Our AC maintenance & tune-up visit covers the full checklist once a year, ideally in spring. Not sure if your system is telling you something? Read the 5 HVAC warning signs.

My AC runs but blows warm air. What's wrong?
The usual suspects are a dirty condenser coil, a failed capacitor, a refrigerant leak, or a frozen evaporator coil from a clogged filter. Start with the AC not cooling guide.
