Los Angeles might not feel like a place where heating is important, but that changes quickly if your furnace stops working on a cold January night in the San Fernando Valley.
Since most LA homeowners only use their heat for a few months each year, problems often go unnoticed until the first real cold snap.
Suddenly, a cracked heat exchanger leaking carbon monoxide, a pilot assembly that won’t respond, or a heat pump that won’t switch to heating can become urgent issues.

Unlike cooling, where most LA homes use some version of central air conditioning, heating systems in this area come in several types. Each has its own maintenance needs, common problems, and replacement options.
Gas furnaces are still the most common heating system in Los Angeles County. They provide quick, powerful heat and are familiar to most homeowners.
Maintenance involves checking the heat exchanger, performing combustion analysis, testing for carbon monoxide, cleaning the ignitor and flame sensor, verifying the gas valve, servicing the blower motor, and inspecting the flue.
If your furnace is 15–20 years old and in need of costly repairs, call us now for a free replacement quote or schedule an installation consultation.
Heat pumps provide both cooling and heating from a single outdoor unit. In LA’s mild winters, they stay fully efficient at temperatures above their minimum rating and use much less energy than gas furnaces for the same amount of heat.
Maintaining a heat pump involves testing the reversing valve, checking the defrost cycle, and inspecting refrigerant levels, which are not needed for gas furnaces.
A dual-fuel system combines a heat pump with a gas furnace backup. The heat pump handles heating during mild weather, which is most of the LA winter, and the furnace only turns on during the coldest nights.
This setup gives you the efficiency of a heat pump while keeping a gas backup, which is a good option for homeowners who are not ready to switch fully to electric heating.

Many older LA homes, especially in West Hollywood, Silver Lake, Echo Park, and pre-war neighborhoods, use wall-mounted gas heaters or floor furnaces as their only source of heat.
These units need a yearly safety inspection that includes checking for gas leaks, testing the thermocouple, performing combustion analysis, and guaranteeing adequate clearance.
If you need to replace one, a ductless mini-split can be a modern and efficient way to heat and cool your home without adding ductwork.
Cooling problems create discomfort. Heating problems can create danger.
Gas furnaces produce combustion byproducts, including carbon monoxide, an odorless, colorless gas that can be dangerous at high levels. A cracked heat exchanger, blocked flue, or a furnace that is not vented properly can let carbon monoxide into your home.
That is why every heating service visit we do includes a combustion analysis and a carbon monoxide safety test. This is not optional or an extra service; it is our basic standard for safe heating work.
If you smell gas, hear a carbon monoxide alarm, or see a yellow or flickering flame: Leave the house immediately.

San Fernando Valley homes have a unique heating profile that most generic HVAC content does not address:
The Valley has short but intense heating needs. Overnight lows often fall into the high 30s and low 40s in December and January, which is cold enough to require heating but not cold enough to cause gradual performance loss. A struggling furnace may get through several winters before it finally stops working.
Many older homes in the Valley, built from the 1960s to the 1980s, still have their original or second furnace. These older systems commonly use standing pilot lights, single-stage burners, and heat exchangers that have gone through decades of heating and cooling cycles. While these furnaces may still turn on, their efficiency and safety are much lower than those of modern equipment.
Duct problems can reduce your heating performance, just like they do with air conditioning in the summer. Hot air moving through uninsulated or leaky ducts in a cold attic loses heat before it gets to your rooms. Upgrading insulation and sealing ducts can improve heating without replacing your equipment.
More Valley homeowners are switching from gas furnaces to heat pumps, thanks to LADWP rebates, higher gas prices, and California’s push for building electrification.
Our technicians look at both repair and replacement options during every heating service visit, so you can make the best choice for your home.
Our Simi Valley branch at (805) 755-4074 offers the same heating contractor services throughout Ventura County. Simi Valley and Thousand Oaks often have overnight temperatures similar to the San Fernando Valley.
Coastal areas like Ventura, Oxnard, and Camarillo have milder winters, but their equipment can suffer from corrosion caused by marine air, which affects outdoor heat pumps, electrical connections, and gas appliances.

If your system takes longer than usual to reach the set temperature, some rooms stay cold while others heat up, or you hear banging, popping, or grinding noises when the furnace starts, it may need attention.
Other warning signs include a burning or metallic smell from the vents, the furnace turning on and off quickly without maintaining a steady temperature, a carbon monoxide detector going off, a yellow or flickering burner flame, higher gas bills despite no increased usage, or the system not responding when you switch to Heat mode.
Any of these warrants a service call. Heating repair →
Repair is usually the best choice if your system is less than 12 years old, the problem is limited to one part, the heat exchanger is in good shape, and the repair costs much less than half the price of a new system.
Replacement is a better option if your furnace is 15 to 20 years old and needs a major repair, the heat exchanger is cracked or damaged, you are making repairs every heating season, the system cannot keep your home comfortable during normal winter weather, or you want to switch from gas to an electric heat pump to get rebates and lower your energy bills.
Contact us today for a direct comparison and advice, so you can choose the best option for your home.
California’s building electrification push and updated Title 24 energy code are changing how heating systems are specified. For new installations in newly constructed homes, heat pump heating is increasingly the standard.
For existing home replacements, the requirements depend on project scope, permit type, and utility territory.

If you are considering a heating tune-up instead of a full replacement, yearly maintenance helps your system run efficiently and can catch safety issues before they become emergencies.

You should have your heating system serviced at least once a year, ideally in the fall before the heating season starts. Even though LA winters are short, a gas furnace that goes without yearly service can build up combustion byproducts, dust, and wear on parts, which can lower efficiency and safety.
Heat pumps should be serviced twice a year—once before cooling season and once before heating season.
Yes. Our technicians are trained on gas furnaces, heat pump systems, dual-fuel configurations, and wall heaters. Gas furnace service includes combustion analysis and carbon monoxide testing. Heat pump service includes reversing valve testing and verification of the defrost cycle.
For many Los Angeles homes, a heat pump is worth serious consideration. It provides both heating and cooling from one system and qualifies for the largest available LADWP rebates.
Because LA winters are mild, a heat pump operates within its efficient range for most of the year — how that affects your utility costs depends on your rate plan, usage, and the efficiency of the equipment it replaces.
Your ductwork and electrical panel capacity also factor into the decision. If you want to keep a gas backup, a dual-fuel system is an option.
We measure CO levels in the flue, at the heat exchanger, and in the living space using a calibrated combustion analyzer.
We also verify a proper draft, inspect the heat exchanger for cracks or corrosion, and check that the flue and venting system are clear and properly connected. This is standard on every gas furnace service visit.
Our $95 diagnostic fee is credited toward any repair you choose to have done. Most standard heating repairs, like fixing the ignitor, flame sensor, capacitor, or blower motor, usually cost between $150 and $650.
Replacing a heat exchanger or performing major repairs can cost $1,200 to $2,800 or more. We always give you a written quote before starting any work.

Mauricio was incredibly helpful and did a great job. He knows his stuff and a great personality!
Upon inspection, I identified a refrigerant leak in the condenser coil of the air conditioning system. The leak was traced to a small puncture in the coil. I safely evacuated the remaining refrigerant and repaired the puncture using specialized tools and materials. After ensuring the repair was secure, I recharged the system with the appropriate amount of R-22 refrigerant. The system was then tested to confirm proper operation and no further leaks.
Completed
Payment was made via credit card, with a 3.5% fee, totaling $936 for the completed job. The task involved a temporary repair, akin to applying a Band-Aid, rather than a permanent solution. The system in question was an 8-year-old unit. Upon inspection, a refrigerant leak was identified as the primary issue. The payment structure included a 50% deposit upfront and the remaining 50% upon completion of the work. The repair addressed the leak, ensuring the system's temporary functionality was restored. However, it is important to note that this is not a long-term fix and further attention may be required in the future.
Well done
During the inspection, both HVAC systems were confirmed to be operating properly. However, several maintenance concerns were identified. For the 5-ton Daikin system, the ductwork had excessive dust and debris, and the outdoor condenser coil was dirty. The condensate drain line was shared with another system, and additional overflow protection was recommended. For the 2-ton heat pump, the condensate pump discharged into the 5-ton system’s drain line, and the emergency drain pan lacked an overflow safety switch. The air ducts and outdoor condenser coil also required cleaning. Recommendations include reconfiguring the condensate drainage, installing overflow safety switches, performing professional duct cleaning, and cleaning the condenser coils.
It was informative, quick, courteous .
I responded to a furnace issue where it attempted to start but shut down. The furnace, a Goodman GMS80703AXA, showed the inducer operating and the hot surface igniter glowing. The igniter measured 57.99 Ω, and the gas valve’s local switch was ON. Despite 27 VAC at the gas valve and steady inlet gas pressure, no gas flow was detected at the valve outlet. Consequently, the burners did not ignite, preventing the heating cycle from completing. The gas valve is likely faulty and needs repair.
