AfterAC Repair & Installation Near You in Pasadena, CA
When your air conditioner quits on a 94-degree August afternoon in Pasadena, you don’t need a callback window. You need a technician who answers the phone, gives you a straight answer, and shows up ready to work. Dalton Heating & Air does exactly that. Call (626) 657-5344 any hour, any day. A live person picks up. Not a voicemail queue.
We provide our ac repair installation services throughout Pasadena, from the historic craftsman homes of Bungalow Heaven to the mid-century builds in Hastings Ranch. Our service area also reaches the surrounding communities, including East Los Angeles, El Monte, Alhambra, Pico Rivera, Monterey Park, Arcadia, and Rosemead. If you’re in the San Gabriel Valley and your AC is down, we’re likely ten to twenty minutes out.
Before any work starts, you get the price in writing. Every repair carries a written guarantee for a full year. Those aren’t add-ons. They’re the way we’ve operated since 2003.
Fast, Local AC Repair & Installation
Most AC repair calls in Pasadena can be scheduled the same day you call. Our technicians are dispatched from within the area, not from across the county, which is why we can typically have someone at your door within a two-hour arrival window. If your system has failed entirely on a hot night, we handle emergency calls around the clock.
What we do on a repair visit: we diagnose the failure, explain the problem in plain language, and hand you a written price before a single part comes off the truck. That price doesn’t change at the door. If the repair doesn’t hold, we return at no charge within the guarantee period. That’s the 365-Day Done Right Promise we run on every job, and it’s been the standard since this company opened.
On the installation side, we handle AC Replacement for full systems, swap out failed condensers, and retrofit older homes that have never had central air. We service nine major residential brands: Carrier, Trane, Lennox, Goodman, Rheem, York, Daikin, Bryant, and American Standard. If your existing system is one of those, our factory-trained techs already know its quirks. If it’s something else, we’ll tell you honestly whether it’s worth repairing or replacing.
Every tech who shows up at your door is background-checked and uniformed. You’ll know the name before arrival. When we leave, the site is clean. Those are the terms of The Garrison Code, and no job closes until they’re met.
Areas We Cover
We run AC repair and installation calls across Pasadena and its bordering neighborhoods. Locally, that includes Old Pasadena, Madison Heights, Linda Vista, Annandale, Oak Knoll, and the hillside streets above the Rose Bowl. Each area has its own typical failures. Up in the hills, we see a lot of systems straining against afternoon sun exposure and poor attic ventilation. Down near the Arroyo, older homes often run original ductwork that’s undersized for modern condenser units.
Beyond Pasadena proper, our service area stretches to home comfort across the San Gabriel Valley. We regularly work in East Los Angeles, where many of the homes were built before central air became standard and need creative retrofit solutions. El Monte and Rosemead bring us a steady stream of heat pump installations and ductless mini-split replacements. In Alhambra and Monterey Park, the dense post-war housing stock means we see a lot of aging compressor failures and refrigerant leaks. Pico Rivera and Arcadia calls tend toward full system replacements, often on homes where the original HVAC is pushing 20 years past its expected lifespan.
If you’re not sure whether you fall inside our coverage area, call (626) 657-5344 and ask. If we can’t get to you, we’ll say so up front rather than waste your afternoon.

What AC Repair Costs in Pasadena
Most AC repairs in the Pasadena area run between $150 and $450, depending on the part that failed. A Capacitor Replacement is the cheapest and most common fix, typically on the low end of that range. A refrigerant recharge, which means topping off the cooling fluid your system needs to hit set temperature, lands in the middle. A compressor replacement or condenser fan motor swap pushes toward the top end.
Here’s how common Pasadena AC repairs break down by part:
- Capacitor replacement: $150 – $250. The startup component that fails most often in San Gabriel Valley heat.
- Refrigerant recharge: $250 – $450. Includes leak testing, because adding refrigerant without finding the leak is just renting time.
- Condenser fan motor: $300 – $500. Common on units that sit in full afternoon sun.
- Contactor replacement: $150 – $300. The electrical switch that tells your compressor to run.
- Thermostat replacement: $150 – $350 depending on the model.
- Compressor replacement: $1,200 – $2,800. At this price point, we’ll often recommend comparing against a new system.
For full system installation, Pasadena homeowners typically pay between $6,500 and $14,000 depending on home size, SEER rating, duct condition, and whether we’re retrofitting an older home. Every quote is written, itemized, and locked before work begins. No shifting numbers, no surprise line items.

FAQs
How fast can you get to my house in Pasadena?
Most calls are scheduled the same day, with a two-hour arrival window. Emergency calls after hours are dispatched as quickly as a tech can route to you. Call (626) 657-5344 and we’ll give you a straight answer on timing before you hang up.
Do you serve my area?
We serve Pasadena and the surrounding cities, including East Los Angeles, El Monte, Alhambra, Pico Rivera, Monterey Park, Arcadia, and Rosemead. If you’re on the edge of that map, call us at (626) 657-5344 and we’ll confirm availability for your street.
What does an AC repair cost in Pasadena?
Most repairs run $150 to $450. Full Compressor Repair replacements and major component work can go higher, and we’ll always tell you before any work starts what the price is, in writing. Estimates are free.
Do you answer the phone after hours?
Yes. A live person answers our phone 24 hours a day, 7 days a week. There’s no voicemail queue. If your AC fails at midnight in the middle of a Pasadena heat wave, you’ll talk to a person, not a recording.
Is it cheaper to repair or replace my AC?
If the failed part costs less than a third of the system’s replacement value and the unit is under 10 years old, repair usually makes sense. If the compressor is gone and the system is past 12 to 15 years, replacement often saves money over the next three years. We’ll walk you through the math with real numbers for your specific unit, then you decide. Call (626) 657-5344 for an honest assessment.
