The most expensive mistake is buying too much machine
Oversizing is the standard error in this trade, and it is an error that gets sold to you as generosity. Bigger sounds safer. Bigger sounds like it will handle the worst day. In practice a system that is too large for the house cools the air very fast, satisfies the thermostat, and shuts off before it has run long enough to pull any moisture out of the air. Then it does it again twenty minutes later.
The result is a house that is 72 degrees and clammy, with hot and cold pockets, and a compressor that is being started and stopped all day, which is the thing that actually wears a compressor out. You paid more for the equipment, you will pay more to run it, and it will die sooner.
The defense against this is a Manual J load calculation: a real measurement of the house, its windows, its insulation, its orientation and its air leakage. Ask for it. A contractor who sizes your system by looking at the old unit and matching it, or by counting square feet and dividing by 500, is guessing, and he is guessing high because guessing high never generates a complaint call in July.
Nobody in Naples needs five tons of cooling in a 1,400-square-foot cottage. Ask what runtime he expects the system to have on an average July afternoon. If he cannot answer, he did not do the math.
The ducts are most of the job, and they are where the bids differ
Here is how two quotes for the same house end up $5,000 apart. One of them is replacing your equipment. The other is replacing your system.
In the slab tracts around Los Altos, El Dorado Park and Bixby Highlands, the ductwork is in the attic, and if the house dates from the 1960s that ductwork is old flex duct in insulation that would not pass anything today. It sags. It kinks at the turns. It comes loose at the boots. Hanging a brand new high-efficiency condenser on that and calling it an upgrade is the most common way a Long Beach homeowner spends twelve thousand dollars and stays uncomfortable.
California actually protects you here, which is unusual enough to be worth saying plainly. Under Title 24, replacing the equipment triggers a duct leakage test verified by an independent HERS rater before the permit closes. Your contractor cannot certify his own work. That test is the reason unpermitted bids look cheaper, and it is the single best reason to refuse them.
What you will actually pay
Permitted, with the HERS test included, for a typical Long Beach house.
- Condenser and evaporator coil swap on existing ducts, three-ton house: $6,000 to $10,000
- Full furnace and AC changeout: $10,000 to $16,000
- Add duct replacement to either of the above: another $4,000 to $8,000
- First-ever central AC in a house with no ducts: $18,000 to $30,000, and please read the next section before you sign that
- Single-zone ductless head: $4,000 to $6,500
If your house has no ducts, think hard before you add them
The pre-1940 bungalows in Rose Park, Carroll Park, California Heights and Bluff Heights were built with a gas wall heater or a gravity floor furnace, and nothing else. No ducts, no returns, no plenum. Owners tend to read that as a defect and ask what full central air would cost.
It costs a great deal, and it means cutting soffits and chases through a house whose proportions are the reason you bought it. Two or three ductless heads will cool that bungalow for well under half the price, with no duct losses at all, and they will heat it too. Go ducted if you want one thermostat and genuinely even temperatures across every room and you have the crawlspace to route it properly. Do not go ducted just because you assume that is what a real system looks like.
Efficiency ratings, minus the sales pitch
The number on the sticker is SEER2 now, not SEER. The old ratings were measured on a test bench that assumed less duct resistance than any real house has, so the industry restated them. A 14.3 SEER2 unit is roughly a 15 SEER unit under the old scale. This matters only because a salesperson quoting you old SEER numbers is either confused or hoping you are.
California sits in the DOE’s Southwest region, which carries a higher minimum than the north does. You cannot legally install the cheapest equipment made. Above that floor, the premium tiers are variable-speed and two-stage compressors, and here we will give you an opinion that a distributor would not.
In a Belmont Shore or Naples house that runs cooling maybe 300 hours a year, the payback math on a top-tier variable-speed system is bad. You will not run it enough to recover the premium, and you should buy it for comfort and quiet if you want it, not because someone showed you a savings chart. Inland, in the tracts that run the condenser from June through October, the argument is much better and the efficiency premium can genuinely earn out. Same city. Different answer. Anyone giving you the same recommendation regardless of where you live is not paying attention.
Ask about a heat pump before you sign
If you are already replacing the air conditioner and your furnace is old, you are two-thirds of the way to a decision you should be making on purpose rather than by default. A heat pump is one outdoor unit that does both jobs. Long Beach essentially never gets cold enough for the usual objection to apply, and there is a federal tax credit plus utility incentives sitting on the table. The full case is on the heat pump installation page, including the situation where the answer is no.
Questions we get
Do I need a permit?
Yes, through Long Beach Development Services, for equipment replacement and for ductwork. Skipping it saves you roughly a thousand dollars today and buys you no HERS test, no inspection, and a disclosure problem when you sell.
How long does the install take?
A straight changeout is a day, sometimes two. Ductwork adds two to four days. The HERS rater comes separately and afterward, which surprises people, so plan for the permit to close a week or two after the crew leaves.
What refrigerant will a new system use?
Equipment sold now runs R-454B or R-32 rather than R-410A, which is being phased down under the federal AIM Act. This is fine and it is not a reason to rush or to delay. It is a reason not to buy leftover R-410A inventory at a discount without asking what the discount is for.
