How Much Does Boiler Replacement Cost in Los Angeles? [2025 Data]

Boiler replacement costs $4,110 in Los Angeles, and most people pay between $2,211 and $6,485 based on boiler and fuel type, home size, boiler capacity, and other cost factors. Los Angeles is known for its sunny, warm weather, but locals know that winters can be surprisingly overcast, rainy, and even a bit chilly. Luckily, a boiler is a low-maintenance heating option that can help keep out the chill.

Boiler Replacement Cost Factors 

Replacing a boiler in Los Angeles, CA, will help you achieve energy-efficient heating in your home or condo. But not all boilers are the same, so the cost to replace a boiler will vary based on your home size, the boiler capacity, the boiler type, and even the fuel the boiler requires.

Size

You can estimate the cost of your boiler by your home’s square footage and boiler capacity using the table below. However, call an HVAC pro in Los Angeles, CA, for the most accurate estimate.

Fuel Type

The most common fuel used for boilers in Los Angeles, CA, is natural gas. The fuel type you choose will have a major impact on both your ongoing costs and how much you pay for a new boiler.

• Oil boiler: Oil burns hotter than gas, so oil boilers provide more heat and are better in colder climates. However, oil boilers require more maintenance than gas options, so keep things like long-term maintenance costs in mind before buying. 

• Gas and propane boiler: Propane and natural gas are common options for heating homes. In addition to the unit price, installation costs $1,000 to $3,000 and requires new exhaust lines, drains, and fuel lines.

• Electric: Electric boilers are highly efficient and don't require some of the components that gas and oil boilers need, like exhaust vents. They take a long time to heat up but are an attractive option for tiny homes in warm climates.

• Wood: Large, outdoor, wood-fueled boilers are good options for rural areas that have easy access to wood. 

System Type

Boilers are broken out by fuel type, but they can also vary in other ways—like their system types.

• Standard or conventional boilers: These boilers work by quickly heating water in pipes and sending it to your taps. Standard units are one of the most popular choices for homeowners in large homes and those with floor heating systems. 

• Combination boilers: Combination boilers are popular because they’ll give you access to hot water quickly. However, the supply tends to be limited due to the lack of a storage tank. 

• System boilers: These work by keeping high-pressure hot water in a sealed cylinder, where it can be sent to multiple taps within your home simultaneously. 

• High-efficiency boilers: High-efficiency boilers are up to 98% efficient, which accounts for thousands of dollars in savings over the boiler's life. Standard boilers are around 80% efficient, making them ideal for cold climates.

Climate Zone

The capacity of your boiler (in BTUs) depends on your region and climate. Warmer climates make it much easier to heat water, even for larger houses, so fewer BTUs are required. You can estimate your necessary BTUs by finding out which climate zone you live in. 

HVAC Pro Costs

Hiring an HVAC pro for boiler replacement costs $75 to $200 per hour, or about $1,200 to $3,200 total. Don’t attempt to DIY this home improvement project. Installing a boiler is a complex job, and any mistakes could lead to fuel or gas leaks. In California, boiler installation should be handled by a pro with C-4 licensing from the Contractors State License Board (CSLB).

Additional Pros to Consider Hiring

In addition to an HVAC pro, you may also hire a plumber for boiler replacement in Los Angeles. Hiring a plumber costs $50 to $200 per hour, per worker. However, an HVAC pro is often the best person to hire for boiler projects since they have specialized skills for handling the fuel, particularly for gas and electric boilers.

Does Boiler Replacement Increase Home Value?

In a warm climate like that of Los Angeles, replacing a boiler won’t have much of an impact on home value. However, if you value having an efficient heating choice during the city’s short but chill winters, a boiler is priceless. Plus, if you invest in a high-efficiency boiler, you could see 10% to 20% savings on your heating costs.
