Heat pump cost in Brentwood is the first number to pin down once the furnace stops being worth another repair. A complete ducted heat pump installation in a typical Brentwood Westside home runs $8,000 to $14,000 depending on system size, ductwork condition, and electrical panel capacity. This page puts that range beside the furnace price so you can see both before you book.
What a heat pump costs in a Brentwood home
The $8,000 to $14,000 range covers the whole job on a ducted house. That means the outdoor unit, the indoor air handler, the connection to your existing ducts, the electrical hookup, the permit paperwork and the start-up test with you in the house.
One system heats in winter and cools in summer. If your air conditioner is also tired, a heat pump can replace both in one visit, and you pay for one install instead of two. A heat pump also removes the gas line and the monthly gas service charge from the picture when you go fully electric.
The low end of the range fits a straightforward swap. The high end fits a house where the ducts, the panel or the outdoor unit location need real work. The next section shows which one you are.
What moves the number: size, ducts, electrical panel, outdoor unit spot
Four things decide where your quote lands.
| Factor | How it moves the price |
|---|---|
| System size | Set by a room-by-room load calculation of your house, not by copying the old nameplate. A bigger system costs more. |
| Ductwork | Sound, sealed ducts keep the job near the low end. Leaky, undersized or collapsed runs add repair or replacement to the quote. |
| Electrical panel | A heat pump needs enough panel capacity. An older panel may need an upgrade, listed as its own line. |
| Outdoor unit spot | Setbacks, HOA screening rules, a tight side yard or a hillside pad change the labor and the materials. |
Brentwood lots make the last row matter. Some Westside homes sit under HOA design guidelines that regulate where outdoor equipment goes. Canyon and hillside properties may need a pad or a wall mount. We confirm the spot during the estimate so it is not a question on install day.
If your house has no ducts, or an addition never got heat, a ductless mini split can heat and cool single rooms without opening walls. That is a separate quote with its own price.
The furnace quote beside it
Gas furnace replacement costs $4,500 to $7,500. It is the lower number up front, and it keeps your system on SoCalGas gas.
Here is how the two compare on one page.
| Heat pump | Gas furnace | |
|---|---|---|
| Up-front price | $8,000 to $14,000 for a ducted system | $4,500 to $7,500 |
| Cooling | Included, one system | Separate air conditioner |
| Gas line | Not needed if fully electric | Stays |
| Electrical work | Panel capacity checked | Usually minimal |
| Outdoor unit | Yes, needs a spot | No |
The price gap shrinks when the air conditioner needs replacing too, because the heat pump covers both jobs. It widens when the panel needs work and your cooling is fine. The quote shows which one fits your house and your budget.
Permits and duct testing on the change-out
Replacing a furnace or a heat pump is permitted work in California. In Brentwood the permit is issued by LADBS, and we handle the paperwork as part of the quote.
Depending on the scope, Title 24 Part 6 can require duct sealing and a duct leakage test. That test is verified by a third-party HERS rater who is not the installer. When it applies, it shows up on your quote as a line item, so you see it before work starts.
New split heat pump systems use lower-GWP refrigerants such as R-454B or R-32. Efficiency appears on the quote as SEER2 for cooling and HSPF2 for heating, so you can compare equipment line by line.
Getting both options quoted in writing
Here is how the quote process runs.
- You send your address, what heats the house now, and whether the air conditioner is also due.
- A technician visits, looks at the ducts, the panel and the outdoor unit spot, and measures the house.
- You get the heat pump and the furnace on the same written quote, each with its own line items.
- The quote is written before any work starts, and you pick the option, or neither.
If your furnace has failed and you need heat now, say so when you book. Our heating installation team schedules replacements, and the heating repair team can look first if a repair makes more sense. If you smell gas, leave the house first, then call SoCalGas or 911 from outside.
