You want an AC unit installation in Brentwood, and you want to know what the job costs and who shows up before you say yes. Brentwood Air sends a technician to the house, runs a room-by-room load calculation, and leaves you a written quote for the whole install. You can request that written quote and visit now, or read on for what is in it.
What an AC unit installation costs in Brentwood
Most complete AC installations in Brentwood run between $6,200 and $11,500 depending on system size, efficiency tier, and whether ductwork modification is required. That figure covers the whole job, not only the box in the yard: outdoor condenser, indoor coil, refrigerant lines, electrical hookup, permit paperwork and a start-up with you present.
Three things place you inside that range:
- Size: the load calculation sets the tonnage, not the old nameplate.
- Efficiency tier: a higher SEER2 rating costs more at install.
- Ducts: if the trunk or returns need changes, that work is priced as its own lines.
What the quote lists
The quote is written before any work starts. Each part of the job gets its own line, so you can compare it with any other bid.
| Line | What it tells you |
|---|---|
| Equipment | Make, model, size and efficiency tier of the condenser and coil |
| Labor | The crew time to set, connect, charge and test |
| Duct or electrical work | Listed apart from the equipment, only if the house needs it |
| Permit | Paperwork for the Los Angeles Department of Building and Safety |
| Start-up | Commissioning with you at the house |
If a line does not apply to your house, it is not on your quote.
Where the condenser goes
Placement is a decision you make with us before the crew arrives. In Brentwood the outdoor unit sits on a pad or a bracket, and the spot has to clear setbacks, any HOA screening rules, and the neighbor's bedroom window. Canyon lots off Mandeville and Sullivan add slopes and tight side yards, so we walk the route from the driveway to the pad during the visit.
If you want the unit moved from where the old one sat, tell us. A new pad, a longer line set or extra electrical run shows up on the quote as a separate line, so you see what the move costs before you choose it.
Install day and the permit
Replacing or adding an AC in California is permitted work. In Brentwood the permit office is LADBS, the Los Angeles Department of Building and Safety, and we handle the paperwork when the project needs it. Depending on the scope, Title 24 Part 6 can require duct sealing and a duct leakage test verified by a third-party HERS rater who is not the installer. When that applies, it is on your quote ahead of time.
On the day, the crew sets the equipment, connects the lines and wiring, charges the system and tests it. Electric service in Brentwood is LADWP, and the condenser ties into your existing panel. If the panel needs work, that is flagged on the quote too. New split systems are made with lower-GWP A2L refrigerants such as R-454B or R-32.
Before the crew leaves, we start the system with you and set up the thermostat. If you want a better one, our smart thermostat setup can go on the same visit.
Replacing a unit that still runs
Some owners call because the AC is dead. Others call because it still runs but the house never cools evenly. Both are install jobs when a load calculation shows the unit was never matched to the house. If the AC is simply broken and might be worth fixing, our AC repair team looks first, and you get the repair price next to the install price. The compressor shows why that comparison matters: when it fails, repair costs range from $1,300 to $3,200 depending on the unit size and refrigerant type. You decide with both numbers on paper.
Why book the visit first
The visit costs you nothing to ask for, and it is the only way to get a number for your house instead of a range. The technician measures, checks the ducts and the pad location, and you leave with a quote you can read at the kitchen table. Our AC installation page lists the systems we put in, and the Brentwood area page covers where we work.
