You need a new furnace and someone told you to go electric. Someone else said gas is the only way. Your neighbor swears by their heat pump. And now you're reading a blog post at midnight trying to figure out which one won't be a $6,000 mistake.
Here's the honest answer from a company that's installed both for 40+ years in Los Angeles: it depends on your house, your gas line situation, and how cold your neighborhood actually gets. Let's break it down.
Most furnace comparison articles are written for the Midwest, where it's 10°F for three months straight. That's not us. LA winters are mild. The coldest it typically gets in the Valley is low 40s at night, and coastal areas rarely dip below 50°F.
This matters because gas furnaces have a clear advantage in extreme cold (they produce hotter air, faster), but that advantage shrinks dramatically when you're only heating your house from 55°F to 70°F. You don't need a flame-thrower to take the edge off a chilly Calabasas morning.
About 70% of LA homes with central heating use gas furnaces. They're common because most homes here were built with gas lines, and gas has historically been cheap in California. Here's what you're looking at:
An electric furnace is basically a giant toaster inside a box with a fan. No gas line, no combustion, no venting. Simple. The problem is cost per BTU.
Here's what we actually recommend for most LA homes: a heat pump. It's technically an electric system, but it works completely differently from an electric furnace. Instead of generating heat by running electricity through a coil, it moves heat from outside air into your home. Think of it as an air conditioner running in reverse.
In LA's mild climate, heat pumps are incredibly efficient. They produce 2-3x more heat energy than the electrical energy they consume. That means operating costs close to gas, with the simplicity and safety of electric.
The only scenario where a heat pump struggles is sustained temperatures below 30°F. That happens maybe 2-3 nights per year in the coldest parts of the San Fernando Valley. Most modern heat pumps have a small backup electric element for exactly those nights.
Go with gas if: You already have a working gas line and gas furnace, your ductwork is in good shape, and you just want a straightforward replacement. No reason to reinvent the wheel if the infrastructure is already there.
Go with a heat pump if: Your AC is also getting old (two-for-one replacement), you're building new or don't have gas lines, you want lower long-term operating costs, or you care about moving away from fossil fuels.
Go with electric furnace if: You have no gas line, your heating needs are minimal (coastal LA, small home), and the install budget is tight. Just know the monthly operating cost will be higher.
We don't push one type over another. We make money either way. But after 40+ years of furnace installations across LA, we've seen what works and what people regret. The biggest regret we hear is from homeowners who replaced a gas furnace with an electric furnace to save on the install, then got sticker shock on their first winter electric bill.
The second biggest regret is people who didn't know heat pumps were an option. If your HVAC system is 15+ years old and both the furnace and AC need attention, a heat pump is worth pricing out. In LA's climate, it's often the smartest long-term choice.
We'll come out, look at your setup, and give you honest numbers for all three options. No pressure, no upsell. Just the math and our recommendation based on what we've seen work for 40 years in this city.
