Why Crestview Heating & Air California Is Novato’s Preferred Emergency & Commercial HVAC Company
Nearly two decades of HVAC experience means we’ve worked on virtually every system type found in Novato’s housing stock, from original forced-air furnaces in the Ignacio tract homes to converted military structures in Hamilton Landing. Our 4.8-star average rating across 250+ customer reviews reflects consistent real-world performance, and several of those reviews come from Novato homeowners who needed emergency service during summer heat events when the rest of Marin stayed fogged in.
Owner Marcus Feldman serves as our Service Manager, so ownership-level accountability is built into daily operations, not just the sales pitch. When you call Crestview, you’re talking to someone with skin in the game, not a dispatch center reading from a script. We understand Novato’s specific geography: the Petaluma Gap winds that accelerate compressor wear, the undersized duct systems in 1970s split-levels, and the retrofit complexity of Hamilton Landing’s ex-military buildings. That local knowledge saves time and money on every job.
Our Emergency & Commercial HVAC Services in Novato
24/7 Emergency HVAC
Systems don’t fail on a schedule. We’ve responded to midnight furnace failures in Hamilton Landing duplexes and Sunday afternoon AC outages on the Novato Boulevard corridor when temperatures pushed past 95°F. Our Emergency & Commercial HVAC team carries common parts for Trane, Lennox, Goodman, and Rheem systems to minimize downtime. For genuine emergencies — no heat during a cold snap, or no cooling when indoor temperatures become unsafe — we prioritize Novato calls and arrive prepared to diagnose and repair on the spot.

Commercial HVAC
Novato’s commercial base includes light industrial near the airport, retail along Redwood Boulevard, and office clusters in the Hamilton Landing business park. These buildings rely on rooftop units, split systems, and occasional chiller equipment that can’t wait for standard business hours. We service commercial systems from 2-ton package units to larger multi-zone setups, and we understand the permitting and noise-ordinance considerations that affect work in Marin County commercial zones.

Rooftop Unit Service
Rooftop units are common in Novato’s commercial and light-industrial buildings, particularly in the Hamilton Landing and Ignacio areas. The combination of summer heat and persistent northwest winds creates a harsh environment for RTU condensers and exhaust fans. We perform full diagnostic service, refrigerant recovery and recharge, economizer repair, and seasonal startup/shutdown programs. Accessing these units safely requires proper rigging and fall protection; this is not DIY territory.

Chiller Service
While less common in residential Novato, chiller systems appear in larger commercial properties and some of the converted military buildings with non-standard mechanical infrastructure. Chiller repairs demand specialized refrigerant handling and electrical diagnostics. Our factory-trained technicians work on equipment from multiple manufacturers, and we maintain the EPA certifications required for large-system refrigerant work.

HVAC Inspection
Before buying a home in Novato’s older neighborhoods — or before listing one — an HVAC inspection reveals what standard home inspections miss. We evaluate duct capacity against current cooling loads, check for asbestos-wrapped ductwork common in pre-1980 construction, and assess whether original furnaces have been retrofitted with cooling coils that exceed the duct system’s design static pressure. For commercial buyers, we inspect RTU condition, remaining service life, and compliance with current Marin County energy codes.

Trusted Brands We Service in Novato
Your system, our specialty. We maintain factory-trained compatibility across nine major brands — Carrier, Trane, Lennox, Goodman, Rheem, York, Daikin, Bryant, and American Standard — so Novato customers are never told “we don’t work on that.” For emergency calls, we stock common Lennox and Goodman control boards, Rheem pressure switches, and Trane contactors locally, which means faster turnaround when your system fails on a Saturday evening. From emergency calls to commercial buildouts, our parts network and technical range keep Novato homes and businesses comfortable.
Common Emergency & Commercial HVAC Problems We See in Novato Homes
- Compressor short-cycling from undersized ductwork. Novato’s 1960s tract homes were built with ducts sized only for heating. When a previous owner or contractor added a cooling coil without upgrading the return air path, the static pressure spikes and the compressor overheats and shuts down repeatedly. We see this constantly in the split-levels near Novato Boulevard.
- Outdoor condenser damage from Petaluma Gap winds. Sustained afternoon gusts of 25–35 mph vibrate fan blades, strain mounting brackets, and scour refrigerant lines. Units installed without wind baffles or proper anchoring suffer failed fan motors and line-set leaks that require emergency refrigerant recovery and repair.
- Original furnace failure in converted Hamilton Landing housing. The mid-century military structures in 94949 contain mechanical chases with non-standard dimensions and odd ceiling heights. When the original oil-fired or early gas furnace fails, a standard replacement often won’t fit, requiring custom fabrication that inexperienced techs underestimate.
- Emergency heat loss in older systems with obsolete parts. Some 1970s furnaces in Novato’s residential core use control boards, ignitors, or blower assemblies that are no longer manufactured. We source aftermarket equivalents or engineer safe workarounds, but in some cases the most cost-effective path is a modern replacement with proper warranty coverage.
Pricing for Emergency & Commercial HVAC in Novato, CA
Honest pricing starts with real numbers. Here’s what typical Emergency & Commercial HVAC work costs in Novato’s market:
| Service | Price Range in Novato |
|---|---|

| Furnace Repair | $150–$700 |
| AC Installation | $3,500–$7,500 |

Emergency calls outside standard hours may carry a modest trip-charge premium, but we quote upfront before any work begins. Commercial rooftop and chiller service is priced per-job based on system size, access difficulty, and parts requirements. The biggest cost variable in Novato is ductwork: adding central AC to a 1960s tract home with undersized ducts can require a full retrofit that adds $2,000–$4,500 to the project, whereas a ductless mini-split bypasses that problem entirely. Call (844) 560-6978 for an exact quote — estimates are free, and we’ll explain every line item before you decide.

FAQs — Emergency & Commercial HVAC in Novato
Yes, we offer emergency HVAC service for Novato residents and businesses, including after-hours and weekend calls for heat failures, dangerous indoor temperatures, and refrigerant leaks. Response time depends on current call volume and your location within ZIP codes 94947, 94948, 94949, or 94998, but we prioritize genuine emergencies. Call (844) 560-6978 anytime — if we can’t get there immediately, we’ll tell you honestly and advise on temporary safety measures.
Probably, if you want proper performance and warranty coverage. Novato’s 1960s–70s tract homes were built with ducts sized only for the CFM requirements of heating; adding a cooling coil increases static pressure beyond what the original return air path can handle. We’ve measured supply plenums in Ignacio and Novato Boulevard corridor homes that are literally half the size modern code requires. A ductless mini-split system often makes more financial sense than tearing out walls to upsize ductwork. Call (844) 560-6978 for a free assessment of your specific layout.
The Petaluma Gap funnels strong northwest winds through Novato’s valley that accelerate wear on outdoor condensers. Fan motors work harder against headwinds, vibration loosens electrical connections, and debris scouring can puncture refrigerant coils over time. We recommend wind baffles, proper anchoring, and annual inspection of line-set insulation and electrical whips. Units installed without these protections often fail 3–5 years sooner than they should. If your condenser is noisy or cycling oddly on windy afternoons, that’s worth a diagnostic call.
Yes, we service and repair commercial rooftop units throughout the Hamilton Landing area and surrounding Novato commercial zones. These buildings often have aging package units that were installed during base conversion in the 1990s–2000s and are now approaching end of service life. We perform seasonal maintenance, emergency refrigerant recovery, economizer repair, and full replacement with properly sized modern equipment. Roof access and fall protection are part of our standard safety protocol. Call (844) 560-6978 to schedule a commercial inspection or discuss a maintenance agreement.
We repair all nine major brands we cover: Carrier, Trane, Lennox, Goodman, Rheem, York, Daikin, Bryant, and American Standard. In Novato specifically, we see a lot of original Lennox and Rheem furnaces in the older tracts, plus newer Goodman and Trane systems in homes that have already been retrofitted. We stock common parts for faster emergency turnaround, and our factory training means we don’t guess at diagnostics. 250+ customers who left reviews agree that technical competence matters. Call (844) 560-6978 to confirm parts availability for your specific model.
