HVAC for North Torrance Homes with Gravity Furnaces
North Torrance has the city's highest concentration of original gravity floor furnaces, 70-to-80-year-old systems whose asbestos-wrapped ducts and aging cast-iron heat exchangers make them the most safety-critical replacements we do. Modernizing one is a specialized project: licensed asbestos abatement first, then a clean heat pump or ducted system that finally adds cooling.
North Torrance homes, mechanically speaking
Built out in the late 1930s through the 1950s around what became El Camino College (founded 1947), North Torrance is a grid of modest 900 to 1,500 square foot single-family homes between the 405 and Torrance Blvd, with the Dominguez Channel marking its eastern industrial edge.
Because gravity furnaces need deep space below the floor for convection, many of these homes sit on raised foundations with deep central pits housing massive cast-iron units. Those same crawlspaces can carry modern insulated ductwork, but only after the old system's hazards are dealt with properly.
What we plan for in North Torrance
Asbestos-wrapped gravity ducts
The octopus-style ducts on original gravity furnaces were almost universally insulated with asbestos. That wrap must not be cut, moved or removed by an HVAC crew; California requires licensed asbestos abatement contractors working under containment. We sequence abatement before demo on every gravity-furnace conversion, and we never shortcut it.
Carbon monoxide risk in aging heat exchangers
Seventy-year-old cast-iron fireboxes crack from decades of thermal cycling, and a cracked exchanger can push combustion gases into the living space. If your North Torrance home still heats with a gravity or floor furnace, an annual inspection and working CO alarms are non-negotiable until it is replaced.
Reusing the deep crawlspace correctly
The deep pits and crawlspaces these furnaces required are an asset for a modern ducted system, but Title 24 HERS duct testing means the new runs must be sealed and insulated, and the crawlspace remediated, so the return side never pulls damp under-floor air into the house.
Rebates, credits & permits: the current facts
Gravity-furnace conversions are the projects incentive programs were made for, which makes the current funding pause especially important to plan around.
Federal 25C tax credit: ended
The federal Energy Efficient Home Improvement Credit (25C) was terminated by 2025 legislation and does not apply to equipment placed in service after December 31, 2025. Do not budget around it for a 2026 project.

TECH Clean California stopped accepting new single-family heat pump incentive reservations on November 14, 2025, and HEEHRA rebates for Southern California single-family homes have been fully reserved since January 7, 2026 (waitlist only). A future funding phase has been discussed but has no announced launch date.

Torrance homes are served by Southern California Edison for electricity and SoCalGas for natural gas. LADWP programs do not apply inside Torrance. Ask us about current SCE-partnered equipment discounts that participating contractors can apply at the point of sale.

Since January 5, 2026 the City of Torrance accepts permit submittals only through its electronic Accela portal. HVAC changeouts, duct changes and mini-split installs all require permits, plus Title 24 (Climate Zone 6) documentation and third-party HERS verification. We pull and manage every permit.

North Torrance questions we hear most
How do I know if my North Torrance home has a gravity furnace?
Look for a large floor grille in a central hallway with no blower sound when heat runs, and a heavy cast-iron unit visible in a deep pit under the house. If your heat rises silently through one big central grille, it is almost certainly a gravity furnace.
Can you just remove the asbestos ducts when replacing my furnace?
Not us, and not any HVAC contractor legally. Asbestos-wrapped ductwork requires a state-licensed asbestos abatement contractor working under containment before mechanical demolition begins. We coordinate that abatement as step one of every gravity-furnace conversion.
What replaces a gravity furnace best?
Most North Torrance conversions go to either a ducted heat pump using the remediated crawlspace for new insulated ductwork, or a multi-zone ductless system that skips ducts entirely. Both finally add air conditioning these homes have never had.
Is it dangerous to keep running an old gravity heater one more winter?
It can be. The failure mode that matters is a cracked heat exchanger leaking carbon monoxide. Before another season, have the exchanger inspected, install CO alarms on every level, and get a replacement plan priced so you are not making the decision mid-cold-snap.
Does the El Camino College area get hot enough to need AC?
Increasingly, yes. North Torrance sits far enough inland that late-summer heat events push well past comfortable, without the beach breeze West Torrance gets. A heat pump conversion solves heating safety and cooling in one project.
