Fast, Reliable Heating & Furnace Across Agoura Hills
Heating and furnace service in Agoura Hills typically runs $150–$700 for repairs and $80–$200 for tune-ups, with most calls handled same-day or next-day. Our Heating & Furnace team knows the 91301 and 91376 corridors well, from the hillside rebuilds off Cornell Road to the original tract homes near Kanan Road. We’ve spent 16 years working California HVAC systems, and Agoura Hills presents a genuinely unique mix: post-Woolsey Fire construction built to strict Title 24 codes alongside 1970s–1990s homes with attic ductwork that bakes past 140°F. Call (855) 467-1888 for a free estimate.
Why Stonegate Heating & Air California Is Agoura Hills’s Preferred Heating & Furnace Company
We’ve earned 499 verified reviews at a 4.7-star average across platforms, and Agoura Hills homeowners make up a meaningful share of that feedback. They mention the same things: Jason Trent showed up personally, diagnosed the real problem, and didn’t push equipment they didn’t need.
Owner Jason Trent holds the title of Field Supervisor, not just Owner. That means company leadership is physically present on job sites, not managing from a back office. When you’re dealing with a cracked heat exchanger in a Cornell Road hillside home or a failed ignitor in a Kanan Dume tract house, that matters.
Our response time to Agoura Hills is typically same-day for emergency calls and next-day for standard service. We stock parts for Carrier, Bryant, and American Standard systems locally, which cuts wait time for Agoura Hills customers who can’t afford a cold night or a failed system during a Santa Ana wind event.
We also understand the local terrain. Agoura Hills sits in a warm inland valley where summer highs hit the mid-to-upper 90s°F and Santa Ana winds push past 100°F with humidity in the single digits. Your furnace and ductwork work harder here than in coastal communities just 15 miles west. And as a Very High Fire Hazard Severity Zone, Agoura Hills keeps post-fire air quality and MERV-13+ filtration a genuine priority, not a sales pitch.
Our Heating & Furnace Services in Agoura Hills
Furnace Repair in Agoura Hills
Furnace repair in Agoura Hills runs $150–$700 depending on the component and accessibility. We see a lot of ignitor failures in the 1970s–1990s tract homes near Kanan Road, where original furnaces have cycled through thousands of Santa Ana-season heat waves. We also find gas valve issues and blower motor failures in post-Woolsey Fire rebuilds, where Title 24 tight homes push equipment harder. Whatever brand you have, we service it.

Furnace Replacement in Agoura Hills
Agoura Hills furnace replacement costs vary with home size and code requirements, but our repair-to-replacement guidance is straightforward: if your heat exchanger is cracked or your system is past 15 years with rising repair bills, replacement usually wins. Post-Woolsey Fire rebuilds in 91301 must comply with California Title 24 2019/2022 energy codes, requiring heat pump-ready infrastructure, duct leakage testing, and solar-ready HVAC design. We handle that compliance paperwork. For surviving tract homes, we size replacement furnaces to account for 140°F+ attic temperatures that degrade performance.

Furnace Tune-Up in Agoura Hills
A furnace tune-up in Agoura Hills costs $80–$200 and pays for itself in efficiency gains alone. We inspect heat exchangers for cracks, test gas pressure, clean burners, and check blower amp draw. In Agoura Hills specifically, we also inspect duct liners for smoke contamination from the 2018 Woolsey Fire, a step most generic tune-ups skip. Santa Ana winds load dust and particulates into outdoor units here, so our tune-ups include deeper coil cleaning than coastal protocols require.

Heat Exchanger Inspection & Replacement in Agoura Hills
Cracked heat exchangers are a safety issue we don’t negotiate. In Agoura Hills, we find them most often in 1970s–1990s furnaces that survived the Woolsey Fire but cycled through extreme thermal stress, and in homes where soot-coated coils restricted airflow and caused overheating. We replaced a 1970s-era furnace in a hillside home near Cornell Road that survived the Woolsey Fire but had soot-coated ductwork and a cracked heat exchanger. The new Carrier gas furnace, paired with upgraded MERV-13 filtration, now handles 100°F Santa Ana days efficiently. If we find a crack, we shut the system down and walk you through replacement options on the spot.

Common Heating & Furnace Problems We See in Agoura Hills Homes
- Smoke-contaminated duct liners and evaporator coils from the 2018 Woolsey Fire. Many homeowners never had a post-fire duct inspection. We routinely discover soot-coated coils and compromised duct liners on routine service calls, a pattern specific to fire-corridor communities that neighboring Calabasas or Thousand Oaks techs encounter far less frequently.
- 1970s–1990s tract home attic ductwork with minimal insulation. Agoura Hills attics regularly top 140°F, and uninsulated or poorly insulated duct runs bleed conditioned air before it reaches your vents. Your furnace works harder, your bills climb, and your comfort drops.
- Builder-grade furnace doors and seals on newer tract homes that leak air. The post-fire rebuilds and newer construction in 91301 often use builder-grade access panels that warp under thermal cycling. We see air leaks around furnace doors that the original installer never sealed properly, wasting energy and drawing unfiltered attic air into the system.
- Failed ignitors and gas valves in high-cycle environments. Agoura Hills’s temperature swings, from 40°F winter lows to 100°F+ Santa Ana events, force more heating and cooling cycles per year than milder climates. Ignitors and gas valves simply wear out faster here.
Pricing for Heating & Furnace in Agoura Hills, CA

| Service | Price Range in Agoura Hills |

What moves you within these ranges? Part type (ignitors run lower than gas valves), system accessibility (attic furnaces in 91301 hillside homes take more time), and whether we find secondary issues like smoke-contaminated ductwork that needs remediation.

FAQs — Heating & Furnace in Agoura Hills
Yes. California Title 24 2019/2022 energy codes require heat pump-ready electrical infrastructure, duct leakage testing, and solar-ready HVAC design for post-fire rebuilds in Agoura Hills. We handle compliance documentation and size systems to meet these standards without overselling equipment you don’t need. Call (855) 467-1888 to review your rebuild’s specific requirements.
Signs include persistent dust or soot around vents, unusual odors when the system runs, reduced airflow, or respiratory irritation that worsens when you’re home. Many Agoura Hills homeowners never had a post-2018 duct inspection. We use borescope cameras to inspect duct liners and evaporator coils for smoke particulate contamination during any service call. If we find damage, we’ll show you and explain remediation options.
Furnace replacement in Agoura Hills typically starts around $3,500 for a standard-efficiency system and can reach $7,500 for high-efficiency units in larger homes or Title 24-compliant installations. Post-Woolsey Fire rebuilds may need additional duct sealing or electrical upgrades to meet code. We provide exact quotes after a free in-home assessment. Call (855) 467-1888 to schedule.
Builder-grade access panels on newer Agoura Hills tract homes often use thin metal or poor gasketing that warps under thermal cycling. The 140°F+ attic temperatures here accelerate that degradation. We replace warped doors with properly sealed panels or add gasket kits that stop air infiltration and attic dust intrusion. It’s a small fix with measurable efficiency impact.
A tune-up ensures your furnace and connected duct system aren’t wasting energy or contaminating air during the cooling season. In Agoura Hills, we specifically clean coils loaded with Santa Ana dust, test for duct leaks that bleed cooled air into 140°F attics, and verify that MERV filtration handles the particulate load from our fire-hazard zone. The result is lower bills and cleaner air when the valley hits 100°F. Call (855) 467-1888 to book.
