How much does a furnace replacement cost in Los Angeles?
A furnace replacement in Los Angeles typically costs $5,210 for an 80,000 Btu gas furnace, installed on the ducts that are already there. The range for that same straightforward swap is $4,060 to $6,980. A 100,000 Btu gas furnace is typically $6,120. A ducted air-source heat pump, replacing the furnace and using those same ducts, is typically $10,360, from $8,080 to $13,880. None of those prices includes new ducts, a chimney liner, or a panel upgrade.
What the Los Angeles labor rate changes
The national starting point for the 80,000 Btu furnace is $4,600 before local labor. Los Angeles labor is 1.26 times a national crew. About 48 percent of that furnace price is the crew, so the city moves the hours more than the cabinet. Versus a crew priced at 1.00, that adds about $610. The heat pump uses a 45 percent labor share because more of its price is the machine. Do not compare a heat-pump quote with the furnace row and call the difference a rip-off. They are different machines.
Which size the example home is even asking about
The example house was built around 1962 and is about 1,550 square feet. stucco bungalows and low-rise apartments, many with wall furnaces and a 100-amp panel Los Angeles has about 1,280 heating degree days, against 4,000 in the national reference. A colder city is the usual reason a quote jumps from 80,000 to 100,000 Btu. That jump is not proof you need it. An oversized furnace short-cycles: the air gets hot, the blower stops, and the house never feels even. This page will not run a Manual J. It will tell you to ask why the quote left the smaller furnace.
What pushes a Los Angeles quote into the high column
Same cabinet location, existing flue or vent that passes, existing gas line, filter door you can reach: that is the typical price of $5,210. The low price is that job with a clear basement or a garage and no code surprise. The high price, $6,980 for the smaller furnace, is a drain on the coil, a condensate pump, a flue that fails inspection, or a second trip. A liner for an old chimney, a move of the furnace to another room, or a duct replacement can honestly sit above the high number. Ask the quote to name those lines. Los Angeles looks mild downtown and behaves like a cooling climate in the Valley. Title 24 paperwork shows up on equipment changes that would be a Saturday job elsewhere. Older bungalows hide knob-and-tube or undersized panels behind stucco, so a mini-split bid that skips the panel is not a bid.
The bill after the Los Angeles install
Install price and the yearly bill are different sentences. At $1.50 a therm — the price you typed in the bar, not a Los Angeles gas tariff — a year of gas heat for the example home is about $360, roughly 238 therms. The same heat from a heat pump at 31.0¢ per kilowatt-hour is about $830 a year, about 2,683 kilowatt-hours. LADWP and SCE territories differ. The planning rate is a metro blend, high by national standards, and time-of-use can make late-afternoon cooling the expensive hours. A heat pump that costs $5,140 more to install does not pay for itself just because the brochure says so. Divide that gap by the yearly difference only if both numbers are for your house. This page will not invent a rebate.
If you rent in Los Angeles
A furnace and a ducted heat pump belong to the owner. The price does not change with the lease. Permission does. Use the range to read a landlord’s number. An “emergency” furnace that is several times $6,980 for a standard swap is a question about scope, not a reason to sign a contract on a building you do not own. Reviewed 2026-09-01.

Installed costs start from published national ranges and scale the labor share. Rents are planning medians, not listings. Reviewed 2026-09-01.
