How much does AC repair cost in Los Angeles?

AC repair in Los Angeles typically costs $150-$550 depending on the issue. Common repairs like capacitor replacement run $150-$300, refrigerant recharge $200-$450, and compressor replacement $1,200-$2,500. We provide free estimates before any work.

How long does an AC unit last in California?

A well-maintained central AC system in Southern California typically lasts 15-20 years. The mild climate means less wear than humid regions, but regular tune-ups are key. If your unit is over 12 years old and needs a major repair, replacement often makes more financial sense.

Why is my AC running but not cooling?

The most common causes are a dirty air filter restricting airflow, low refrigerant due to a leak, a failing compressor, or a frozen evaporator coil. Start by replacing your filter. If the problem persists, call us — refrigerant leaks require a licensed technician.

How often should I service my AC in Los Angeles?

We recommend a professional AC tune-up once a year, ideally in spring before peak cooling season. In LA, where AC runs most of the year, bi-annual service (spring and fall) is even better. Regular maintenance extends equipment life and prevents costly emergency repairs.

Common AC Problems in Los Angeles

Living in the San Fernando Valley means your air conditioner works hard. Here are the most common issues we see:

Blowing warm air. Often caused by low refrigerant, a dirty filter, or a failed compressor.
Weak airflow. Clogged filters, blocked ducts, or failing blower motors reduce airflow.
Constant cycling. Short cycling can mean an oversized system, dirty coils, or a faulty thermostat.
High humidity. Poor airflow or low refrigerant prevents the system from removing moisture.
Loud noises. Buzzing, rattling, or squealing usually points to electrical or mechanical problems.
Water leaks. Clogged condensate drains can overflow and damage ceilings or walls.

AC Installation and Replacement

If your AC is over 15 years old, needs frequent repairs, or cannot keep up with summer heat, a new system may save you money and improve comfort. Upright performs Manual-J load calculations, recommends the right SEER2 rating for the Los Angeles climate, and handles permits, rebates, and installation. We install central air, heat pumps, and ductless mini-splits.

AC Maintenance Plans

Regular AC maintenance prevents breakdowns, lowers energy bills, and protects your warranty. Our maintenance plan includes two tune-ups per year, priority scheduling, and repair discounts. We clean coils, check refrigerant, inspect electrical components, and document every visit with photos and readings.

Emergency AC Repair

AC failures do not wait for business hours. Upright offers 24/7 emergency AC repair from offices in Van Nuys, Sherman Oaks, and Woodland Hills. We stock common parts and complete most repairs in a single visit. Call (818) 219-2684 any time for emergency service.

Why AC Sizing Matters

An oversized AC cools the home too quickly, leading to short cycling, humidity problems, and uneven temperatures. An undersized system runs constantly and cannot keep up on the hottest days. Upright performs Manual-J load calculations for every installation to match the system to your home’s exact needs.

AC Efficiency Ratings Explained

Air conditioner efficiency is measured by SEER2. Higher numbers mean lower operating costs. In Los Angeles, where systems run five to six months a year, upgrading from a 10 SEER unit to a 16 SEER2 unit can significantly lower your electricity bill. We help you balance upfront cost, rebates, and long-term savings.

AC Repair vs. Replacement

Repair is usually the best option for systems under 12 years old with minor issues. Replacement is smarter when the system is over 15, needs a compressor, or has repeated failures. We always give honest guidance and provide written quotes for both repair and replacement options.

AC Maintenance Checklist

Our AC tune-up includes checking refrigerant levels, cleaning coils, inspecting electrical connections, testing capacitors and contactors, measuring airflow, and inspecting ductwork. We also change filters and document everything for warranty and service history.

When to Call for Emergency AC Repair

Call Upright immediately if your AC stops working during extreme heat, you smell burning, you see ice on the coils, or you hear loud grinding or screeching. These issues can damage the system further or create safety risks if left unaddressed.

Preparing Your AC for Summer

Before the first heat wave, schedule a professional tune-up, change the air filter, clear debris from around the outdoor unit, and test the thermostat. Check vents and returns for blockages and make sure ceiling fans are set to spin counterclockwise. These simple steps help your AC run efficiently when temperatures spike.

Our technician will arrive on time, introduce themselves, and inspect your system. For repairs, we diagnose the issue, explain the problem, and provide an upfront quote. For installations, we measure and evaluate your home before recommending equipment. We protect your floors, clean the work area, and test the system before leaving.

Frequently Asked Questions About Air Conditioning

How often should I service my AC?

We recommend a professional tune-up once a year, ideally in spring. Heat pumps should be serviced twice a year because they both heat and cool.

How much does AC repair cost?

Common repairs range from $180 for a capacitor to $1,200+ for refrigerant leak repair. We apply the diagnostic fee to the repair if you proceed.

Do you install ductless mini-splits?
