AC Replacement Without the Pressure
Central air conditioner replacement is the largest cooling job we do, so we treat the visit as a proper assessment, not a sales call.
Same-day service available: call early and we'll get to you today in most cases. Emergency calls answered 24/7. If your AC has stopped altogether, we come out to diagnose it first. Plenty of breakdowns are a fair repair, and we will say so.
What happens when you call
- You talk to a person. Tell us what the AC is doing, roughly how old it is, and when you are home. We book a time that suits you.
- We come and look. A technician checks the outdoor unit, the indoor coil and furnace, the ducts and the electrical supply, and measures the house.
- You get it in writing. Repair options, replacement options, or both, each with a fixed price. No pressure to decide on the spot.
Signs It Is Time to Replace Your AC Unit
One sign on its own rarely settles it. Two or three together usually do.
- It is 15 years old or more. Central air here tends to last around 12 to 17 years, less near the coast, where salt air eats at the outdoor coil.
- It runs on R-22. R-22, the refrigerant many people still call Freon, stopped being made or imported in the US at the start of 2020. Most systems installed before about 2010 use it. Every top-up now comes from dwindling recycled stock and is expensive.
- A big repair is on the table. A failed compressor, a leaking indoor coil or a second major repair in two summers is the usual tipping point.
- Your summer bills keep climbing. Older, worn equipment runs longer to do the same job.
- Some rooms never get comfortable. Hot bedrooms and a cold hallway can mean poor sizing or tired ducts.
If you are not sure, our AC repair visit answers the question for the price of a service call, and that fee is applied to the repair if you go ahead with one.
Repair or Replace? The Honest Maths
Here is the rule of thumb we use, and we will show you the numbers on your own system. Multiply the age of the unit in years by the cost of the repair. If the result is well under $5,000, repairing is usually the smart move. If it is well over, replacing usually is. In between, it comes down to how the system has behaved and how long you plan to stay.
Two quick examples. An 8-year-old AC with a failed capacitor at $300 scores 2,400. Fix it and move on. A 17-year-old R-22 system that needs a leak repair and a refill scores far higher, and it will still be a 17-year-old R-22 system afterwards. That money is better put towards the new one.
Replacing a healthy system to chase a small saving on the bill rarely makes sense. Pouring a large repair into equipment at the end of its life only delays the same decision.
Sizing Done Right: Measure, Do Not Copy
Air conditioners are sold by the ton. One ton means the unit can remove 12,000 BTUs of heat an hour, and a typical Orange County house uses somewhere between 2 and 5 tons. The mistake we see most often is a new unit sized to match the old label, with no one checking whether the old label was right.
We work out the size with a load calculation, the room-by-room method the trade calls Manual J. It accounts for square footage, insulation, window size and direction, ceiling height, and how much afternoon sun each side of the house takes. A home in a cool coastal neighbourhood and an identical one inland in Anaheim can need quite different units.
Why bigger is not better
An oversized AC blasts cold air, satisfies the thermostat in a few minutes and switches off. Then it does it again. That on-off habit, called short cycling, leaves the air clammy because the unit never runs long enough to pull out moisture. It wears the compressor faster, it leaves far rooms uncomfortable, and you paid extra for capacity you did not need.
We also measure airflow through the existing ducts, because a new unit is only as good as the ducts feeding it. If they leak or are undersized, we price the fix separately through our ductwork repair service.
Choosing Your New AC Unit
SEER2, in plain words
SEER2 is the efficiency rating for air conditioners. Think of it as miles per gallon: the higher the number, the less electricity it takes to keep the house cool. Since 2023 the ratings have used a tougher test that reflects real ductwork, which is why SEER2 numbers look a little lower than the old SEER numbers. Every system we install meets California's current minimum, and going higher pays back fastest in hot inland homes.
Single-stage, two-stage or variable-speed
Single-stage is on or off, full blast or nothing. It is the simplest and lowest-cost option, and fine for many homes. Two-stage has a gentle low setting for mild days and a full setting for heat waves, so it runs longer and quieter and handles humidity better. Variable-speed adjusts in small steps, running most of the time at just the output the house needs. It gives the most even temperatures, the quietest outdoor unit and the lowest running cost, at a higher purchase price. Our variable-speed AC installation page goes into more detail.
A heat pump split system: the AC that also heats
From the street, a heat pump split system is hard to tell apart from central air: an outdoor unit, a pair of copper lines and a coil indoors. The difference is a small valve that lets it run in reverse, so it heats the house in winter as well as cooling it in summer. Orange County's mild winters suit it well.
If the AC has to be replaced anyway, it is worth putting a heat pump price next to the straight AC price. It costs more than an AC swap, but it also takes over the furnace's job, and the old gas furnace can stay on as backup (the trade calls that dual fuel) or be swapped for an electric air handler later. See our heat pump installation page, and ask us which utility or state incentives currently apply to your address, since they change often.
No ducts? A mini-split instead
Plenty of older Orange County homes and room additions were never built with ducts. A ductless mini-split puts a slim wall unit in each room, connected to one small outdoor unit, and most of them heat as well as cool. Read more on our ductless mini-split installation page.
The same kind of system is the usual answer for a converted garage, a home gym or a backyard ADU, where tying into the house ducts makes little sense. Heat pump mini-splits for garages and ADUs are a growing part of our work, and the circuit or subpanel they need is ours to add. Our garage and ADU mini-split page covers the details.
New refrigerants mean a matched indoor coil
New home air conditioners now use newer refrigerants, R-454B or R-32, which are far kinder to the climate than the R-410A and R-22 they replace. The outdoor unit has to be paired with an indoor coil built for the same refrigerant, so a proper replacement includes a new matched coil above your furnace or in your air handler. A quote that swaps only the outdoor box is not comparing like with like.
What Does a New AC System Include?
A proper AC system replacement is more than the box in the side yard. When you line up two or three quotes, check that each one covers the same parts. Ours are listed one by one on the written estimate, so you can see what is new and what is being kept.
- The condenser. This is the outdoor unit most people picture, with the compressor, the outdoor coil and the large fan on top. Its job is to throw the heat from your rooms out into the yard.
- A matched indoor coil. The coil sits on top of the furnace or inside the air handler and is where the cooling actually happens. It must suit the new refrigerant and be rated together with the condenser, otherwise the efficiency printed on the sticker is not what you get.
- The line set. Two copper pipes run between the outdoor unit and the coil. Where the old ones are the right size and sound, we flush them and pressure-test them for reuse. Where they are undersized, kinked or corroded, new copper goes in.
- The thermostat. Some older thermostats were never made to run two-stage or variable-speed equipment. We check yours, and if it needs to go, a compatible one is written into the estimate. A smart thermostat is an option, not a requirement.
- The pad. The outdoor unit should sit level on something solid. Old concrete slabs sink and tilt over the years, so we either level what is there or set down a new pad.
- The disconnect. This is the shut-off box on the wall beside the unit, plus the short flexible conduit, called a whip, that feeds it. Near the coast these rust out, and we would rather replace them than connect a new condenser to a corroded switch. That part falls under our C-10 electrical licence.
- The permit. A city mechanical permit, the Title 24 refrigerant charge and duct leakage checks, and the final inspection. We apply, we book it and we meet the inspector.
- The small things that matter. Condensate drain connections, a safety float switch where the coil drains over a ceiling, recovery of the old refrigerant and hauling the old equipment away.
What is not bundled in unless you ask: a new furnace, new ducts or panel work. If the house needs any of those, each one is its own line with its own price, so you can say yes to one and no to another.
New Air Conditioner Cost in Orange County, 2026
These are typical ranges. Your own price comes from a free written estimate after we have measured the house, and it is agreed in writing before any work starts.
| Job | Typical Cost | What to Know |
|---|---|---|
| AC changeout, 3 ton | $6,500 – $9,500 | New outdoor unit and matched coil; efficiency level and access set the final figure |
| AC changeout, 4–5 ton | $8,500 – $13,000 | Larger or two-storey homes; variable-speed sits at the upper end |
| Heat pump system (ducted) | $9,000 – $16,000 | Heats and cools; replaces the AC and can replace or back up the furnace |
| Furnace replacement | $4,200 – $7,800 | Only if the furnace is also near the end; saves labour done together |
| Ductless mini-split, single zone | $3,500 – $5,500 | One room or addition with no ducts |
| Evaporator coil replacement | $1,200 – $2,600 | On its own, a repair; on an old R-22 system, a reason to compare with replacement |
| Refrigerant leak search & repair | $350 – $1,500 | Worth doing on a younger system; think twice on an old R-22 unit |
| Duct sealing | $600 – $1,800 | Often needed to pass the Title 24 leakage test |
| Ductwork replacement (whole house) | $4,500 – $9,500 | When the old ducts are crushed, torn or badly undersized |
| Dedicated HVAC circuit | $450 – $1,200 | New breaker, wiring and disconnect for the outdoor unit |
| Panel upgrade to 200A | $3,000 – $6,500 | When the home needs more capacity; done by our own electricians |

The Electrical Side, Handled by the Same Company
Most AC replacements plug straight into the existing circuit. Some need more: a larger unit, a heat pump with backup heat strips, or a new location for the outdoor unit. When that happens, a lot of AC installers have to stop and send you off to find an electrician.
We hold a C-10 electrical licence as well as our C-20 heating and air conditioning licence, so the electrical part is ours too. If the panel is at its limit, the next step might be using spare capacity that is already there, adding a subpanel, fitting a right-sized inverter unit that draws less power, or a full electrical panel upgrade to 200 amps. We price it on the same estimate and schedule it around the install, so you deal with one company and one set of permits.
What Installation Day Looks Like
Most straightforward air conditioning replacements are finished in one day. Here is roughly how it goes.
- Morning arrival. We confirm the plan with you and lay down floor protection along the path to the furnace or air handler.
- Old refrigerant recovered. Our EPA 608 certified technicians recover the refrigerant properly rather than venting it.
- Old equipment out. The outdoor unit and old coil are removed and hauled away. The pad is levelled or replaced.
- New system in. New outdoor unit, matched coil, and copper lines replaced or cleaned and tested, depending on their size and condition.
- Vacuum, charge and test. The lines are pulled into a deep vacuum, charged to the manufacturer's specification, and the system is checked for airflow, temperature and electrical readings.
- Walk-through. We show you the thermostat, the filter and anything new, then leave the site clean.
Permits, Title 24 and Our Licence
Replacing an air conditioner in any Orange County city needs a mechanical permit and a city inspection. California's energy code, Title 24, usually adds a duct leakage test and a refrigerant charge check, often confirmed by an independent rater. We pull the permit under our own licence, book the inspection and meet the inspector.
Skipping the permit can look like a saving. It is not. Unpermitted work tends to come up when you sell the house, and manufacturers may refuse warranty claims on equipment that was not installed to code.
Check any contractor before they start, us included. Search licence #1108650 at cslb.ca.gov and you will see both our C-20 and C-10 classifications, bond and insurance status. Our certified technician page explains what to look for.
AC Replacement Across Orange County
The equipment is the same everywhere; the houses and the weather are not. Whether it is an AC unit replacement or a first-time air conditioning installation, here is what tends to shape the job in the cities around our Fountain Valley shop.
- Anaheim, roughly 20 minutes away. Inland summers keep a new AC busy from June into October, so a higher-efficiency unit pays back faster here than on the coast, especially in the two-storey homes of Anaheim Hills.
- Santa Ana, just north-east of us. Many homes predate central air entirely, so a first install often means new ducts and more electrical capacity, both priced on the same estimate.
- Irvine. Older villages such as Woodbridge and Turtle Rock date from the 1970s, and many still have their original attic ducts on a second or third outdoor unit, so we test the ducts before we size anything.
- Huntington Beach, right next door. Salt air shortens the life of outdoor coils close to the water, so where the unit sits and whether a coated coil is offered are worth a conversation.
- Costa Mesa, about 10 minutes. Ranch tracts like Mesa Verde often have the condenser squeezed into a narrow side yard, so we plan placement around noise and the neighbour's bedroom window, not just size.
- Garden Grove, about 12 minutes. Late-1950s homes with a hall-closet furnace and a modest electrical service often need a new circuit or panel work alongside the AC, and that is our own C-10 work.
Drive times are rough and depend on traffic. We cover the rest of the county too, from Westminster and Tustin to Newport Beach and beyond. If you searched for AC installation near me, we are probably closer than you think.
AC Replacement Questions, Answered
How much does it cost to replace an AC unit in Orange County?
For a straight swap of a central air conditioner in 2026, most homes land between $6,500 and $9,500 for a 3-ton system and between $8,500 and $13,000 for a 4 to 5-ton system. Where you fall inside that range depends on the efficiency level, whether you choose single-stage, two-stage or variable-speed, how easy the indoor coil is to reach, and whether the copper lines can be reused. We give you a free written estimate after we have seen the house, so the figure you approve is the figure you pay.
How fast can you replace my air conditioner?
It depends on stock and paperwork more than on labour. When the equipment is in stock locally and the job is a straightforward changeout, we can often schedule installation within a few days of you approving the estimate, and the install itself usually takes one day. Jobs that add ductwork, a new circuit or a panel upgrade can take a second day. If your AC has quit in a heat wave, call first: same-day service is available in most cases if you call early.
My old AC is 3 tons. Shouldn't the new one just be 3 tons too?
Maybe, but nobody should assume it. The old unit may have been sized by guesswork, and the house may have changed since, with new windows or attic insulation. We run a room-by-room load calculation and check the ductwork before choosing a size. Sometimes the answer is the same tonnage. Quite often it is half a ton smaller, which costs less to buy and to run. An AC that is too big cools the air quickly, shuts off before it has pulled out the humidity, and cycles on and off all day.
Will a new air conditioner need a bigger electrical panel?
Usually not. A modern condenser of the same size usually draws similar or less power than the one it replaces. When the new setup does need more, such as a larger unit, a heat pump with backup heat strips, or a new circuit to a new location, that is work we do ourselves under our C-10 electrical licence. Depending on the house, the answer might be a new dedicated circuit, a subpanel, or an upgrade to 200 amps. We tell you which one at the estimate, with the price written next to the AC so there are no surprises.
Should I replace my furnace at the same time as the AC?
Not automatically. If the furnace is under about 12 years old, runs safely and has a blower that suits the new AC, keeping it is usually sensible. If it is the same age as the old air conditioner, doing both together often saves labour, because the indoor coil sits on top of the furnace and has to be changed anyway. It is also the moment to ask whether a heat pump makes sense instead, since a heat pump heats and cools with one outdoor unit.
Do you offer financing and what payment do you take?
Yes. 0% financing is available on approved credit, and you can see the details on our financing page before you call. For payment we take credit card, check, Zelle and cash. Nothing is due before we agree the written estimate, and the price on that estimate does not change after you sign. We will also check whether any utility or state incentives apply at your address, because those programmes change often and we would rather look it up than guess.
Do you install new AC in Anaheim and Santa Ana?
Yes. We install and replace air conditioners throughout Orange County, including Anaheim, Santa Ana, Irvine, Huntington Beach, Garden Grove, Costa Mesa and Fountain Valley, where our shop is. Anaheim is roughly twenty minutes away, depending on traffic. Each city runs its own building department, so the permit is pulled with whichever city you live in, and we handle the application and the inspection. If your old AC gives out before the new one is booked, same-day and 24/7 emergency service cover these cities too.
Can I replace just the outdoor unit and keep my old indoor coil?
It is the cheaper quote on the day, which is why people ask, but with today's equipment it rarely works out. A replacement AC unit now runs on R-454B or R-32, and the indoor coil has to be designed for that refrigerant and rated as a pair with the outdoor unit. Mix old and new and you lose efficiency, you can put the manufacturer's warranty at risk, and the old coil is often the next part to leak. The honest exception is a recent coil that the manufacturer lists as a match for the new condenser. We read the model numbers on both and tell you which case you are in.
