Furnace repair in Newbury Park typically runs $150 – $700, and most calls get a same-day or next-day visit. We know the difference between a quick ignitor swap and a 1970s slab-foundation duct problem before we even ring your doorbell. If your heat is out on a 40-degree January night, or you’re smelling something hot from the vents, call (831) 539-0291 and a live person answers. Not a voicemail tree.

Newbury Park’s mix of 1960s-to-1980s single-family homes, original galvanized ducting, and newer Dos Vientos construction means furnace failures follow patterns we’ve mapped over hundreds of service calls. We tell you the price in writing before any work starts. And we tell you exactly who’s walking through your door, by name and photo, before they arrive.
Why Brandt HVAC Co Ventura Is Newbury Park’s Preferred Furnace Repair Company
Newbury Park homeowners call us because we treat an older furnace the way a good mechanic treats a 1972 pickup: we look for the real problem, not just the symptom. Our Furnace Repair team has worked on enough Carrier, Lennox, and Goodman units in Rancho Conejo and Camino Dos Rios to know that a tripped breaker is often the 100-amp panel, not the furnace. We say so plainly. No upsell, no vague “you probably need a new one.”
Every repair includes a written guarantee. If the fix fails within the guarantee period, we come back free of charge under the 365-Day Done Right Promise. That’s not marketing language. That’s the standard Devin Marlowe set for every Brandt HVAC location, including here in the Conejo Valley.
Response time to Newbury Park neighborhoods like Dos Vientos, Rancho Conejo, and the Wendy Drive corridor is usually same-day for no-heat calls during winter. We’re a local crew, not a call center booking jobs from another state. Dispatch is coordinated from our Los Angeles office, and we schedule Newbury Park work with technicians who know the area’s streets and housing stock.

Styles & brands we work with







Furnace Maintenance in Newbury Park
Furnace Maintenance in Newbury Park means preparing a heating system for mild but real winter cold snaps, where nights drop into the 40s and a furnace that’s been idle since March suddenly has to perform. A maintenance visit in Newbury Park runs $80 – $200 and includes a combustion check, heat exchanger inspection, gas pressure verification, blower amp draw test, and a written report of what we found, what we fixed, and what might fail next season. We recommend October, before the first cold snap, because scheduling a tune-up in January means waiting behind emergency no-heat calls.
Pre-Winter Combustion and Safety Check
We test carbon monoxide output at the vent, confirm the flame sensor is clean, and check for any rust or cracks in the heat exchanger. In Newbury Park’s marine-layer-influenced climate, heat exchangers in slab homes see more moisture than you’d expect, and that corrosion is the silent killer we look for first.
Blower and Static Pressure Review
The blower motor moves air. If static pressure is too high because original ducts are undersized or collapsed, the blower works harder and fails sooner. We measure it in inches of water column and tell you if your ducts, not your furnace, are the actual bottleneck.
Heat Pump Repair in Newbury Park
Heat Pump Repair in Newbury Park is growing as homeowners in Dos Vientos and newer developments replace aging gas furnaces with electric heat pumps. These systems work hard in the Conejo Valley’s warm, dry summers and can struggle on the handful of winter nights that dip into the 40s, especially if the thermostat is miscalibrated or the auxiliary heat strips are firing when they shouldn’t. Repair costs fall into the same $150 – $700 range for most component replacements.
Thermostat and Control Diagnosis
A heat pump that runs endlessly on auxiliary strips during a mild 50-degree Newbury Park evening is usually a thermostat wiring or programming fault. We trace the control voltage and set the lockout temperature correctly, so you’re not paying strip-heat rates on a 55-degree day.
Refrigerant and Coil Service
Heat pumps move heat, not create it, so refrigerant level and coil cleanliness decide whether the system actually warms your Dos Vientos home. We check both, clean what’s fouled, leak-test the lines, and give you a written price for any recharge before we touch a valve.

Trusted Brands We Service in Newbury Park
We service Rheem, York, Daikin, and Bryant furnaces and heat pumps in Newbury Park, along with most other major residential brands. Because so many older Rancho Conejo homes still run original Rheem or York units from the 1980s and 1990s, we keep common parts like ignitors, flame sensors, gas valves, and blower motors stocked on our local trucks. That means a no-heat call in Camino Dos Rios doesn’t wait three days for a part to ship from a warehouse in Texas. We arrive with the likely fix on board.
Common Furnace Repair Problems We See in Newbury Park Homes
- Tripped breakers from aging electrical panels. A 1970s Carrier in a Camino Dos Rios home trips the breaker because the 100-amp panel can’t handle the new blower motor’s inrush. The furnace is fine. The panel is the problem, and we tell you before you spend $700 on a part you don’t need.
- Collapsed or corroded original galvanized ducts. Unlike neighboring Thousand Oaks where ductwork routes through accessible basements, Newbury Park’s slab-on-grade homes bury ducts in concrete. Corrosion from the Santa Monica Mountains’ marine layer is invisible and expensive to reach, and it’s why a like-for-like furnace swap often leaves rooms just as cold.
- Short-cycling from undersized ducts and add-on rooms. Homeowners replace a Goodman with the same tonnage but ignore that original 6-inch ducts were sized before a 1980s add-on room. The new furnace short-cycles, far bedrooms never satisfy, and the gas bill climbs.
- Heat pump control faults in newer builds. Trane systems in Dos Vientos run on auxiliary strips during winter cold snaps because of a miscalibrated thermostat or weak capacitor. That produces a hot panel smell and a July-sized electricity bill in January.

FAQs About Furnace Repair in Newbury Park
The new thermostat is almost certainly wired wrong for a single-stage 1970s furnace, or it’s configured as a heat pump when you have a gas furnace. We fix the wiring and reconfigure the thermostat in one visit, usually for $150 – $250. Then we test the full heat cycle and stay until the registers blow warm. Call (831) 539-0291 for a same-week appointment.
Yes, a properly sized heat pump keeps a Dos Vientos home warm on 40-degree nights. The failures we see come from undersized systems, miscalibrated thermostats, or electric strips running when they shouldn’t. A cold-climate heat pump rated for these temperatures works. A bargain unit sized for summer cooling does not. We’ll tell you which is which and give you a fixed price before ordering anything.
Usually not. West-side rooms in Newbury Park’s older tracts sit farthest from the furnace, and original 6-inch ducts were often undersized before an add-on or a remodel. The furnace is producing heat. The ducts can’t deliver it. We measure static pressure and airflow room by room, then fix the duct side, which is the actual repair. Call (831) 539-0291 for an airflow test.
Every year, ideally in October. Newbury Park’s marine layer pushes moisture toward the Santa Monica Mountains, and slab-on-grade homes trap that dampness around buried ducts and furnace cabinets. A rusted heat exchanger is a carbon monoxide risk and a hidden one. We inspect it during an $80 – $200 maintenance visit and show you photos of anything concerning.
It’s most likely both. In a 1964 slab home, the original galvanized ducts have likely corroded and collapsed in sections, which makes the furnace work harder to push heat through a shrinking passage. Our tech traced a $430 bill spike in a 1977 Rancho Conejo home to exactly this: a rusted Lennox heat exchanger plus a corroded evaporator coil plus a collapsed original duct under the slab. We fixed the furnace components, then the real fix required opening a section of slab to reroute that duct. A like-for-like swap would have left the house just as leaky. Call (831) 539-0291 and we’ll diagnose both the machine and the ducts before recommending anything.
