Heating Systems — Furnace, Heat Pump & Ductless

Gas Furnace Repair and Replacement

A gas furnace is the most common heating system across the service area, and furnace not heating is the most common emergency heating call the region generates every winter. Many communities in the San Fernando Valley and Santa Clarita Valley experience genuine January cold — foothills neighborhoods regularly drop below 35°F overnight, and a non-functional furnace stops being an inconvenience and becomes a health concern within hours.

Most furnace not heating situations are caused by a failed ignitor ($150-$350), a dirty flame sensor ($75-$250), or a tripped safety limit switch from restricted airflow. All three are diagnosable and fixable in a single visit. When the issue is more serious — a failed control board ($400-$900), a draft inducer motor ($350-$800), or a cracked heat exchanger ($1,500-$3,500) — the licensed technician provides a side-by-side repair vs. replacement comparison before recommending anything.

Furnace replacement across the service area runs $2,800-$6,500 for a gas furnace depending on BTU capacity and efficiency rating. High-efficiency models at 96%+ AFUE cost more upfront but deliver lower SoCalGas bills over a 15-18 year lifespan.

Furnace Maintenance — The Annual Service Most Homeowners Delay

Furnace maintenance is the most cost-effective investment in any gas furnace's operational life. A tune-up running $80-$200 catches the failing ignitors, dirty flame sensors, and cracked heat exchangers that cause $300-$900 emergency calls in January. It also covers the heat exchanger inspection that is the most important safety check a licensed technician performs on a gas system each year.

A proper furnace maintenance visit covers: heat exchanger inspection for cracks (CO safety), burner cleaning and combustion analysis, flame sensor cleaning, ignitor testing, gas pressure check, airflow measurement, blower motor inspection, and filter assessment. Most manufacturer warranties require documented annual HVAC maintenance service to remain valid.

Heat Pump Installation Across the Service Area

Heat pump installation is increasing across both the San Fernando Valley and the Conejo and Santa Clarita communities as homeowners replacing aging furnaces discover that an air source heat pump handles both heating and cooling in a single system. Modern heat pumps maintain full capacity down to 0°F, well below the region's typical winter range.

A hybrid heating system — pairing an air source heat pump with a gas furnace backup — is one of the most practical configurations for Southern California's inland communities. The heat pump handles all heating when outdoor temperatures stay above 35-40°F, while the gas furnace covers the genuinely cold foothills nights. Federal IRA tax credits of up to $2,000 apply to qualifying heat pump systems. Central heat pump installation runs $4,000-$8,500. Hybrid heating system installation runs $6,000-$12,000 including both units.

Ductless Mini Split Installation for Homes Without Ductwork

A large share of the pre-1975 housing stock across the San Fernando Valley was built without central ductwork and relied on baseboard heaters or wall heaters for heat. Ductless mini split installation bypasses the $4,000-$8,000 duct retrofit cost entirely. A 3-inch wall penetration for the refrigerant line is all the structural work required.

A ductless mini split heat pump provides both heating and cooling in a single unit. Single-zone ductless mini split installation runs $2,500-$4,500. Multi-zone systems covering 2-5 rooms run $5,500-$13,000. Mitsubishi, Daikin, and Fujitsu are commonly specified across the service area for their reliability in sustained high-temperature conditions.

Licensed Heating Contractors and HVAC Installers

Every furnace installation, heat pump installation, and ductless mini split installation requires a mechanical permit and California Title 24 Part 6 energy compliance inspection. The HVAC installer performing the work must hold a valid California C-20 HVAC contractor license. Every contractor in HVAC Services Team's partner network has verified licensing and general liability insurance on file before they receive any referral.

Scheduling furnace installation or replacement in September or October avoids the December rush when HVAC contractors across the region are fully booked and installation timelines extend significantly into winter.

Other Heating Technologies

• Electric furnace: Present in homes without natural gas service. Higher operating costs per BTU than gas and generally being replaced with heat pumps at end of life.
• Baseboard heater: Found in some older homes as primary or supplemental heat. High operating costs make these strong candidates for ductless mini split upgrades.
• Heat recovery ventilator (HRV): Improves indoor air quality in tightly sealed homes by exchanging stale indoor air with fresh outdoor air while recovering heat energy. Often recommended for newer energy-efficient homes.
• Geothermal heating system: Uses ground loops for heat exchange rather than outdoor air. Highly efficient but requires significant site work. For most homes in the service area, an air source heat pump delivers comparable long-term efficiency at far lower installation cost.
• Hydronic heating: Radiant systems using hot water through floors or baseboard radiators. A specialty installation most practical in new construction rather than the existing residential stock across the service area.
