AfterAC Replacement in Pasadena, CA
AC replacement in Pasadena typically runs $8,500 to $16,500 for a complete system swap, depending on home size, ductwork condition, and the efficiency rating you choose.

Call (626) 657-5344 for a written quote before any work begins.
Replacing an air conditioner is not a repair call. It’s a decision that determines how comfortable your home will be for the next 12 to 18 years. That’s why we approach every replacement as a system evaluation, not a box swap. If a repair will get you another few reliable summers, we’ll say so. If we recommend replacement, we’ll show you the numbers in writing and explain exactly why. For repair-focused questions, start with our AC Repair & Installation in Pasadena page.
Dalton Heating & Air is a Garrison Partners company, in operation since 2003. Marco Benitez leads the Pasadena team, and every job follows The Garrison Standard: arrive inside the stated window, put the price in writing before starting, install by the book, leave the site clean, and stand behind the work for a full year.

When You Need AC Replacement
Some systems fail suddenly. Others fade over two or three summers, leaving you with rising electric bills and rooms that never quite cool, sometimes signaling you need a Refrigerant Recharge. Here are the signs we see most often in Pasadena homes:
- Your system is 12 years old or older. The average air conditioner in Southern California lasts 12 to 15 years. If yours is in that range and needs a major repair, replacement is usually the better financial call.
- The compressor failed. The compressor is the pump that circulates refrigerant. In Pasadena’s summer heat, a compressor replacement often costs 40 to 60 percent of a new system. We’ll show you both numbers and let you decide with the full picture.
- It uses R-22 refrigerant. R-22 was phased out years ago. If your system leaks, recharging it means buying reclaimed refrigerant at prices that climb every year. A new system uses R-410A or newer refrigerant, which is cheaper to service and better for the environment.
- Repair bills are stacking up. If you’ve spent more than $1,200 on repairs in the last two years, that money is going into a machine that’s already past its prime. At some point, replacement stops being an upgrade and becomes the cheaper option.
- Rooms are uneven or never reach set temperature. In older Pasadena homes, especially around Bungalow Heaven or the Craftsman neighborhoods north of the 210, undersized or aging ductwork can make some rooms 10 degrees warmer than others. A replacement with a proper load calculation fixes that.
- Your system is a Goodman or Lennox unit nearing end of life. Even well-built brands wear out. High desert dust, coastal humidity shifts, and 90-degree September heat all take a toll. We service all nine major residential brands, and we’ll tell you honestly whether a specific unit deserves another repair.
Our AC Replacement Process
We walk every replacement through the same steps, in the same order, every time. No shortcuts, no surprises.
- In-home evaluation and load calculation. A technician walks the house, measures square footage, checks window orientation, insulation levels, and existing ductwork. We use a Manual J load calculation to size the system. Wrong sizing wastes money and shortens equipment life.
- Written proposal with options. You get two or three equipment options with pricing in writing before any work starts. We’ll explain the difference between a 14 SEER and a 17 SEER system in plain terms: SEER is the efficiency rating, and higher SEER means lower monthly bills.
- Equipment selection and scheduling. We install Carrier, Trane, Lennox, Goodman, Rheem, York, Daikin, Bryant, and American Standard. The right brand depends on your budget, efficiency goals, and existing ductwork. We schedule the install at a time that works for you, and the crew arrives inside the stated window.
- Removal and installation. The old system comes out, the new one goes in. We protect floors, keep the work area clean, and handle all refrigerant recovery and disposal by the book. No shortcuts, no debris left behind.
- System startup and airflow balancing. We start the system, check refrigerant charge, test airflow to every register, and verify the thermostat works correctly. If a room is still uneven, we adjust dampers before we leave.
- Written guarantee and customer walkthrough. Every replacement includes our written one-year guarantee. We show you how to operate the system, what maintenance looks like, and how to reach us if anything comes up. Under the 365-Day Done Right Promise, if the work doesn’t hold up, we return at no charge.
AC Replacement Pricing in Pasadena
Replacement cost depends on three things: system size, efficiency rating, and the condition of your existing ductwork. A 1,200-square-foot condo in Old Pasadena needs a smaller system than a 3,000-square-foot house in the San Rafael Hills. Here’s what full replacement typically runs in Pasadena, including equipment, installation, and permits:
| System Type | Home Size | Typical Installed Cost |
|---|---|---|
| 14 SEER single-stage, basic | Up to 1,500 sq ft | $8,500 – $11,000 |
| 16 SEER single-stage, mid-grade | 1,500 – 2,500 sq ft | $11,000 – $14,000 |
| 17 – 18 SEER two-stage, high-efficiency | 2,000 – 3,000 sq ft | $13,000 – $16,500 |
| Ductwork replacement (add-on) | Whole home | $3,500 – $8,000 additional |
These are honest ranges based on jobs we’ve completed in Pasadena, not bait pricing. The exact quote depends on what we find during the in-home evaluation. If your ductwork is intact and your electrical panel has capacity, you’ll land at the lower end. If we need to run a new circuit or replace rusted ducts, the number moves up and we’ll show you exactly why.
Every quote is free, in writing, and itemized. You’ll know the equipment price, the labor price, and the permit fee before you sign anything. No money down until you approve the job.
FAQs – AC Replacement
How much does AC replacement cost in Pasadena?
AC replacement in Pasadena typically runs $8,500 to $16,500 depending on the size of your home, the efficiency rating you select, and whether your ductwork needs work. A full system swap on a moderate-sized home usually lands around $11,000 to $14,000. Call (626) 657-5344 for a free in-home evaluation and an exact written quote.
Can you replace my AC the same week?
Yes, in most cases we can schedule your replacement within the same week, and we’ll arrive inside the stated window.

Is it cheaper to repair or replace my AC?
If your system is under 10 years old and the repair is under $600, our AC repair installation services usually make sense. If your system is over 12 years old or the compressor has failed, replacement is usually the better financial decision over the next five years. We’ll show you both options in writing and let you decide. Call (626) 657-5344 for an evaluation and honest recommendation.
