Car A/C Repair & Recharge in Pasadena, CA

Blowing warm during a Pasadena heat wave? We diagnose why, fix the leak or failed part, and recharge the system to spec.

When it's 100 degrees in Pasadena, a car A/C that blows warm isn't an inconvenience, it's a problem. Walnut Smog & Repair handles A/C diagnosis, repair and recharge the right way: find out why the system lost its cooling, fix that, then recharge to the exact amount your vehicle calls for.

Why "just add refrigerant" isn't a fix

An A/C system is sealed. If it's low on refrigerant, it has a leak. A can from the parts store might give you cold air for a few weeks, but it risks overcharging the system and can add sealers that clog expensive components. We check pressures, find the leak, and tell you what's actually wrong.

Common A/C problems

Leaking hoses and seals, condensers damaged by road debris, compressor clutches that stop engaging, and electrical faults in pressure switches or relays are all common. If the air is cold on one side and warm on the other, the issue may be a blend door actuator. Weak airflow often means a clogged cabin air filter.

Get ahead of summer

Have the A/C checked in spring, before the first heat wave, when everyone else's breaks too. Read more in our post on why car A/C blows warm. Call (626) 449-6252.
