Car A/C Blowing Warm Air? Common Causes

In Southern California, a weak A/C isn't a small problem. Here's what usually causes it.

Low refrigerant (a leak)

A/C systems are sealed. If the refrigerant is low, there's a leak — at a hose, seal, condenser or evaporator. 'Recharging' without fixing the leak is a temporary fix.

Compressor or clutch

If the compressor doesn't engage, nothing gets cold. Causes include a failed clutch, a fuse or relay, or a pressure switch.

Condenser or cooling fan

The condenser sits in front of the radiator. If it's blocked, damaged (a common result of front-end collisions) or the fan doesn't run, A/C gets weak in traffic.

Works sometimes, not always

Intermittent A/C is often electrical: a sensor, a relay, a blend door actuator or a wiring problem. These need proper diagnosis, not guessing.

What we do

We check pressures, look for leaks, test the electrical side and give you a written estimate.

FAQ

Is it OK to use an A/C recharge kit from the store?

It may help briefly, but overfilling can damage the compressor, and it doesn't fix the leak.

This article is general information, not legal or insurance advice. Rules and policies change — check your policy and the official source, or ask us.

*Deductible assistance of up to $1,000 is available only on insurance claims where your insurance company has approved a repair amount of $8,000 or more and the repair is performed in accordance with that insurer-approved estimate (California Penal Code § 551(b)). We never increase a repair estimate to cover a deductible. Not available on customer-pay repairs. Ask us for details before your repair begins.

**Free computer diagnostic scan: we read and explain your vehicle's trouble codes at no charge, no purchase required. If the problem needs in-depth testing (labor), we give you a written estimate and get your approval before any paid work, as California law requires.

†Warranty: limited lifetime warranty on our collision, body and paint workmanship for as long as you own the vehicle; 24 months / 24,000 miles (whichever comes first) on mechanical repairs, parts and labor. Not covered: normal wear, new damage, abuse or neglect, rust or chips from road debris, and customer-supplied parts. Warranty terms are written on your invoice.

‡Accident towing: you pay nothing out of pocket when you have collision coverage or the other driver is at fault — we pay the tow and bill the insurance company. If no insurance covers the tow, we tell you the price before the truck is sent.
