AfterAC Replacement in Los Angeles, CA
AC replacement in Los Angeles typically runs between $6,500 and $14,500 for a full system, depending on home size, efficiency rating, and ductwork condition. Most replacements are completed in a single day when the existing ductwork is sound. At Cold Harbour Heating and Air Los Angeles, we give you a written price before any work begins, and our technicians are trained on nine major brands including Rheem, York, and Daikin. If your current system is past its prime, call us at (213) 531-5904 for a free estimate. You can also learn more about our broader AC Repair & Installation in Los Angeles services.
We’ve been replacing air conditioners across Los Angeles since 2003 as an independently owned member of the Kingswell network. A cold harbour was a roadside shelter where travelers waited out rough weather, and that’s the job we’ve taken on here: keeping your home comfortable no matter what the valley heat brings in August.
When You Need AC Replacement
Not every cooling problem means a new system. But there are clear signs that replacement makes more sense than another repair. Here’s what we see across Los Angeles neighborhoods from Silver Lake to Woodland Hills:
- Your system is 12 to 15 years old and needs a major repair. When a compressor or coil fails at that age, you’re often putting $2,000 to $3,500 into a machine that’s already near the end of its life.
- It runs on R-22 refrigerant, also called Freon. Production of R-22 was phased out years ago, and prices for a recharge have climbed sharply. Converting to a modern system with R-410A ends that expense for good.
- Summer electric bills keep climbing even when usage stays flat. Older systems in Los Angeles run hard from June through October, and an aging condenser burns more power to produce the same cooling.
- Rooms heat up unevenly. If one bedroom stays chilly while the living room feels like a sauna, the system or ductwork is no longer distributing air effectively.
- Repairs are stacking up faster than one a year. A capacitor one season, a fan motor the next, then a leak. At a certain point, replacement is the cheaper path.
- Your system uses a now-discontinued or hard-to-source brand. Some older units simply lack available parts, which strings out every repair by days or weeks during peak Los Angeles heat.
If any of these sound familiar, a replacement quote will at least give you a real number to compare against continued repairs. We’ll walk you through the tradeoff without pushing you either way.
Our AC Replacement Process
We follow the same written steps on every replacement job in Los Angeles. It’s part of The Kingswell Way: say the price before the work, show up in the window given, leave the place cleaner than found, put the guarantee in writing, and come back if it fails.
- Free in-home assessment. A background-checked technician from Cold Harbour Heating and Air Los Angeles walks your home, measures the living space, inspects the ductwork, and checks the electrical panel. No charge for the visit.
- Written price before any work begins. You get a printed quote showing the full cost of equipment, labor, permits, and haul-away of the old unit. That number doesn’t change at the door.
- System sizing and selection. We size the unit to your home’s square footage and sun exposure, not just the old unit’s rating. Then we walk you through brand options like Rheem, York, and Daikin so you can compare efficiency and warranty.
- Installation day, on the window we promised. Our technicians arrive in uniform, protect your floors, remove the old equipment, install the new condenser and indoor coil, and connect the refrigerant lines properly. This includes a full nitrogen pressure test and vacuum pull to verify the system is tight before charging.
- Startup, testing, and cleanup. We run the system through a full startup sequence, measure airflow and temperature split at the supply and return, and hand you the thermostat basics. Your place is left cleaner than we found it.
- Written guarantee and walkthrough. Before the technician leaves, you get the guarantee on paper, along with the equipment warranty registration handled for you. If the new system fails within 365 days, we return and make it right at no charge.
AC Replacement Pricing in Los Angeles
We’ll tell you straight: Los Angeles AC replacement prices vary more than repair prices because the equipment itself carries the biggest cost. Here are the ranges we most often quote for single-family homes in the city:
- Entry-level 3-ton system (14-15 SEER): $6,500 to $8,800 installed
- Mid-range 3.5-ton system (16-17 SEER): $8,800 to $11,500 installed
- High-efficiency 4-5 ton system (18-20 SEER): $11,500 to $16,000 installed
- Ductwork replacement (when needed): $4,000 to $9,000 additional, depending on home size and access
- Electrical panel upgrade (if the panel is undersized): $1,500 to $3,500 additional
What Affects the Price
Home size is the biggest driver because it determines tonnage. A 900-square-foot condo in Koreatown takes a 1.5 to 2-ton unit, while a 3,000-square-foot house in Encino often needs a 5-ton. The efficiency rating also matters: a higher SEER costs more up front but lowers monthly bills, which matters in Los Angeles where air conditioners run well into October. Access matters too. A rooftop unit in a hilly area like Echo Park takes more labor than a ground-level condenser in the flats of Culver City, and may need Capacitor Replacement sooner due to heat exposure.
Every quote we write is itemized so you can see exactly where the money goes. The price we hand you before the work starts is the price you pay. Call (213) 531-5904 for a free estimate and we’ll size your home correctly the first time.

FAQs – AC Replacement
How much does AC replacement cost in Los Angeles?
Most full-system AC replacements in Los Angeles run between $6,500 and $14,500, with the final number determined by home size, efficiency rating, ductwork condition, and access difficulty. We provide a written itemized price before any work begins, and the estimate is free. Call (213) 531-5904 for an exact quote on your home.
Is it cheaper to repair or replace my AC?
If your system is under 10 years old and the repair costs less than $1,500, repair usually wins. If the unit is over 12 years old, runs on R-22 refrigerant, or needs a Compressor Repair, replacement is often the smarter financial move. We’ll show you the numbers side by side and let you decide.
How long does AC replacement take in Los Angeles?
Most replacements finish in a single day, typically 6 to 10 hours from arrival to final walkthrough. Jobs requiring new ductwork or an electrical panel upgrade may take two days. We give you a firm arrival window and a written price before the first tool comes out.
Can you replace my AC same week in Los Angeles?
In most cases, yes. We keep common condenser and coil sizes in local Los Angeles supply stock, and our technicians can often schedule replacement within three to five business days. During peak summer heat, call (213) 531-5904 and we’ll give you the soonest available window.
Do you offer a guarantee on AC replacement?
Yes, in writing. Every Cold Harbour Heating and Air Los Angeles replacement is covered by the 365-Day Done Right Promise. If the installation fails within that year, we return and correct the work at no charge. The guarantee is handed to you on paper before the technician leaves.
