Fast, Reliable Heating & Furnace Across Agoura
Furnace repair in Agoura typically runs $150–$700, while full replacement costs $3,500–$7,500 depending on your home’s size and whether it sits in a post-Woolsey rebuild zone. We’re Crestview Heating & Air California, and our Heating & Furnace team makes the drive from our base to Agoura regularly — usually same-day or next-morning for calls placed before noon. You can reach us at (844) 560-6978.
Agoura’s valley geography creates heating challenges you won’t find in flatter Ventura County cities. The Santa Monica Mountains and Simi Hills channel Santa Ana winds straight through town, and that same wind-tunnel effect that amplifies summer heat also drives winter cold snaps harder than in Thousand Oaks or Westlake Village. Your furnace works harder here. We’ve learned that over 19 years of HVAC work, including plenty of winter mornings driving the 101 to service calls off Kanan Road and Chesebro.
Why Crestview Heating & Air California Is Agoura’s Preferred Heating & Furnace Company
Our 4.8-star rating across 250+ reviews includes enough Agoura and Agoura Hills customers that we know the local patterns. Owner Marcus Feldman still serves as Service Manager, which means when you call Crestview, you’re not getting a dispatcher reading from a script. You’re getting an owner-managed operation where accountability runs through one person who’s been in the field for nearly two decades.
We’ve replaced furnaces in Liberty Canyon rebuilds and coaxed another season from aging Rheem units in the original 1970s tracts near Reyes Adobe Road. That range matters. Agoura’s housing stock splits between two distinct eras — pre-Woolsey suburban development and post-2018 custom construction — and the heating systems in each require completely different expertise. We carry both.
Response time to Agoura is typically same-day for standard calls and prioritized for no-heat emergencies, especially during the first cold snap of November when systems that sat idle through summer suddenly reveal the damage Santa Ana winds and fire-season ash inflicted. Emergency HVAC service is available when your furnace fails outside normal hours.
Our Heating & Furnace Services in Agoura
Furnace Repair
Most Agoura furnace repair calls we field involve ignitor failures, gas valve corrosion, or control board issues — often in 1970s–80s tract homes where smoke particulate from the Woolsey Fire settled into electrical contacts and sat dormant for months. A typical furnace repair in Agoura runs $150–$700. We stock ignitors and gas valves for Goodman, Rheem, and Lennox systems commonly found in the area, which means fewer return trips and faster heat restoration.

Furnace Replacement
Replacement demand in Agoura splits two ways: homeowners in original tracts finally retiring 20+ year systems, and rebuild owners discovering their contractor-grade furnace was improperly sized for their new open-plan layout. A furnace replacement in Agoura costs $3,500–$7,500. Post-Woolsey rebuilds require careful Manual J load calculations — the wind exposure off Kanan Dume Road and those high ceilings in custom homes mean the square-footage rule of thumb fails. We calculate properly. On a custom rebuild in the Liberty Canyon neighborhood, we replaced a fire-damaged Carrier furnace with a 96% AFUE model paired with a MERV-16 filter cabinet and a motorized fresh-air damper that seals during smoke events. The homeowner wanted whisper-quiet operation for their home theater and smart thermostat integration — we matched the new system to their existing Daikin heat pump for seamless zoning.

Furnace Tune-Up
An Agoura furnace tune-up runs $80–$200 and should happen before the first sustained cold, not after. In this town, that means checking blower wheels for packed ash from prior fire seasons — something we find even in homes that “survived” the Woolsey Fire intact. We inspect heat exchangers for micro-cracking caused by extreme thermal events, test gas pressure, and verify that fresh-air intake dampers close properly. Skipping this in Agoura carries higher stakes than in cities without fire-history.

Heat Exchanger Inspection & Replacement
Heat exchanger work in Agoura ranges $150–$700 for repair or replacement of the component itself; full furnace replacement may be recommended if the unit is older. This is where post-Woolsey conditions hit hardest. We’ve found ash-packed secondary heat exchangers with micro-cracks that leak carbon monoxide when the furnace first kicks on after summer. The danger is real and specific to this area. If you smell smoke when your furnace starts, or if your CO detector has chirped even once, call us. This isn’t a DIY inspection — heat exchanger cracks require professional detection equipment and, if confirmed, immediate replacement.

Trusted Brands We Service in Agoura
Your system, our specialty. We service and stock parts for Carrier, Trane, Lennox, Goodman, Rheem, York, Daikin, Bryant, and American Standard — the nine brands that cover virtually every furnace installed in Agoura over the past forty years. The 1970s tracts near Driver Avenue lean heavily on original Lennox and Rheem units. Post-Woolsey rebuilds in Morrison Ranch and Liberty Canyon tend toward Carrier and Daikin higher-efficiency lines. We don’t tell Agoura customers “we don’t work on that.” With 19 years of factory-trained experience across all nine brands, we fix what you have. Parts availability means faster turnaround, and faster turnaround means less time without heat when the Santa Ana winds drop temperatures overnight.
Common Heating & Furnace Problems We See in Agoura Homes
- Ash-packed secondary heat exchangers in post-Woolsey homes. Systems that tested fine on paper after the fire often harbor packed blower wheels and cracked heat exchangers. The first sustained heat cycle of winter exposes micro-cracks that leaked nothing during a brief post-rebuild test. We find this in Agoura more than neighboring cities because of the intensity and duration of smoke exposure here.
- Failed ignitors and gas valves from corroded electrical contacts. Smoke particulate is acidic. It sits on circuit boards and in valve solenoids through summer, then causes intermittent no-heat calls during the first cold snap. Agoura’s 1970s–80s tract homes with original wiring are especially vulnerable — the combination of aged components and fire-season corrosion fails all at once.
- Oversized furnaces in fire-rebuilds with poor Manual J calculations. Custom homes with open ceilings and large glass areas need precise load calculations. Contractors who oversized “to be safe” install furnaces that cycle rapidly, create temperature swings, and fail prematurely. We’ve corrected this in multiple Agoura rebuilds where the original installer never returned.
- Capacitor and control board failures in wind-exposed outdoor units. Agoura’s valley-gap wind tunnel doesn’t just affect summer cooling. Winter Santa Anas drive dust and debris through condenser cabinets, stressing electrical components that then fail when the heat pump or furnace calls for auxiliary heat. Systems that “survived” the fire often didn’t survive the particulate load.

FAQs — Heating & Furnace in Agoura
If your furnace operated during or immediately after the fire, you should have it professionally inspected for heat exchanger micro-cracks and blower wheel ash contamination, even if it seemed to function normally. The extreme thermal event and months of particulate exposure create failure modes that don’t show up in casual observation. We’ve found systems that tested fine on paper but were one heating season away from CO leakage. Call (844) 560-6978 for an inspection — estimates are free.
There’s no rule-of-thumb answer for Agoura’s custom rebuilds — we perform a full Manual J load calculation accounting for ceiling height, glass area, wind exposure, and your home’s specific orientation in the valley. Oversizing is the most common mistake we correct in post-Woolsey homes, where rapid cycling creates hot and cold zones in open plans. A properly sized 80,000 BTU furnace often outperforms an oversized 100,000 BTU unit.
VHFHSZ rules primarily govern exterior construction and ember-resistant vents, but they do affect how we route combustion air intake and exhaust penetrations through fire-rated assemblies. Your furnace itself doesn’t need to be a special “fire zone” model, but the installation must comply with current Title 24 energy codes and local amendment requirements that apply to Agoura rebuilds. We handle this as part of replacement planning.
Smoke odor on first heat almost always indicates residual ash and particulate in the blower compartment, heat exchanger, or ductwork from fire-season exposure. In Agoura, this is a frequent post-Woolsey call we receive each November. It’s not normal “dust burn-off.” Schedule a tune-up and inspection — we’ll clean the assembly and check for heat exchanger damage that could be releasing combustion byproducts into your air.
Yes, with the right control retrofit. Most 1970s furnaces in Agoura’s original tracts can accept a modern smart thermostat with proper wiring assessment — usually adding a C-wire or using a power-stealing adapter. We evaluate your existing control board compatibility and recommend thermostats that work with your specific brand and model. Integration with zoning dampers or heat pumps (common in Agoura dual-fuel setups) requires additional planning but is absolutely achievable.
