We’ve been driving out to Rohnert Park from San Jose for years, and we know this planned city inside out. The uniform tract phases from the 1960s through the 1980s created neighborhoods where the same furnace models were installed by the dozen. That repetition works in your favor when you need service. We’ve repaired Goodman units on Country Club Drive, replaced Lennox systems in the Rancho Verde section, and tuned up Rheem furnaces in homes backing onto the golf course. When your heat goes out on a January morning and the marine layer is rolling through the Petaluma Gap, you want someone who recognizes your system before they even open the access panel.
Why Crestview Heating & Air California Is Rohnert Park’s Preferred Heating & Furnace Company
Nearly two decades of HVAC experience means we’ve worked on virtually every furnace configuration Rohnert Park’s housing stock can throw at us. Owner Marcus Feldman still serves as Service Manager, so the person answering your questions on the phone is the same person ensuring the job gets done right. That ownership-level accountability isn’t a slogan here. It’s how we operate every day.
Our 4.8-star average across 250+ customer reviews reflects consistent real-world performance. Rohnert Park homeowners specifically mention our willingness to explain the condition of aging ductwork and our honesty about when a repair is throwing good money after bad. We’re not going to sell you a new furnace if your 1985 Rheem has another five years with a heat exchanger cleaning and a new ignitor.
Response time matters in Rohnert Park’s cool, damp winters. When the fog sits low and your furnace fails, temperatures inside a slab home drop fast. We prioritize emergency heating calls and keep common failure parts in stock. From the 94926 zip code through 94927 and 94928, we aim to get a technician to your door with the right equipment.
Our Heating & Furnace Services in Rohnert Park
Furnace Repair
A typical furnace repair in Rohnert Park runs $150–$700. The most common calls we get are failed ignitors and gas valves on 1970s and 1980s furnaces that have been cycling through damp, salt-tinged air for decades. The cool marine airflow through the Petaluma Gap keeps summers mild, but that same moisture accelerates rust and sediment buildup inside burner assemblies. We’ve replaced more ignitors in Rohnert Park’s original southwest sections than anywhere else in Sonoma County. If your furnace is blowing cold air, cycling erratically, or refusing to start entirely, we’ll diagnose it honestly and have the parts to fix it that day in most cases.

Furnace Replacement
Full furnace replacement in Rohnert Park costs $3,500–$7,500 depending on system size, ductwork condition, and whether we’re routing new supply lines around slab-embedded ducts. Here’s where Rohnert Park’s planned-city history creates real complexity. That 1964 slab home on Huntington Drive we mentioned? The original Carrier gas furnace was still running, but the homeowner wanted central AC for the first time. When we opened the slab, we found the old galvanized heating supply ducts had collapsed and were embedded in the concrete. No patching possible. We replaced the entire air-distribution system with new flex duct in the attic and installed a Trane 2.5-ton split system. The job took three days instead of one. Not every replacement is that involved, but we’ll tell you before we start if your duct situation demands a full rebuild.

Furnace Tune-Up
An annual furnace tune-up in Rohnert Park costs $80–$200 and pays for itself in efficiency gains and avoided breakdowns. We inspect heat exchangers for cracks, clean burner assemblies of rust and sediment, test gas pressure and ignition sequence, and measure airflow against your system’s specifications. In Rohnert Park’s oldest neighborhoods, we pay special attention to the condition of original galvanized ductwork. Undersized or corroded return lines force your furnace to work harder, shortening its life and spiking your gas bill. A tune-up catches these issues before they become January emergencies.

Heat Exchanger Inspection and Replacement
Cracked heat exchangers are a safety issue we take seriously. In Rohnert Park’s vintage furnaces, decades of thermal cycling through damp winters create stress fractures that can leak carbon monoxide into your living space. We inspect with visual tools and combustion analyzers. If replacement is needed, we’ll show you the damage and explain whether it makes sense to repair a 30-year-old unit or invest in a new system. Your system, our specialty. We service Trane, Lennox, Goodman, and Rheem units regularly, and we stock replacement heat exchangers for the most common models found in Rohnert Park’s 1960s–1980s housing stock.

Trusted Brands We Service in Rohnert Park
We maintain factory-trained compatibility across nine major brands, and we keep parts inventory prioritized for what we actually encounter in Rohnert Park. Lennox and Carrier dominated the earliest construction phases. Goodman and Rheem became prevalent in the 1970s and 1980s expansions. Trane systems appear frequently in later builds and retrofit installations. Because we see the same models repeatedly across this city’s uniform housing stock, our technicians often know the failure pattern before they step inside. That familiarity translates to faster diagnosis and repairs that stick. We don’t tell you “we don’t work on that.” If it heats your home, we can service it.
Common Heating & Furnace Problems We See in Rohnert Park Homes
- Corroded condenser coils and electrical connections. The salt-laden marine air funneled through the Petaluma Gap accelerates corrosion on outdoor HVAC components, especially for homes near Rohnert Park’s southern edge closest to San Pablo Bay. We see pitted contactors and degraded capacitor terminals that cause intermittent failures.
- Undersized original ductwork causing airflow problems. The 1960s–1970s galvanized and flex ducts in Rohnert Park’s earliest homes were engineered for heating loads only. When homeowners add even a modest cooling demand, the existing supply lines can’t move enough air. Rooms stay cold in winter and won’t cool in summer.
- Failed ignitors and gas valves on aging furnaces. Decades of operation in cool, damp conditions leave rust and sediment on burner assemblies. The ignitor cracks from thermal stress. The gas valve sticks or leaks. These are predictable wear items on 1970s–1980s furnaces, and we stock replacements for same-day repair.
- Slab-embedded duct collapse. In the oldest 1960s sections, original heating ducts were cast directly into concrete foundations. When they corrode or collapse, there is no access for repair. The entire distribution system must be abandoned and rebuilt overhead or in crawlspaces.

FAQs — Heating & Furnace in Rohnert Park
Probably not, if your home has slab-embedded ducts. The 1968 construction phase in Rohnert Park used concrete-slab foundations with galvanized supply lines cast directly into the concrete. These ducts were sized only for heating airflow and cannot handle the higher volume central AC requires. We’ve inspected dozens of these homes. When the slab ducts are intact, they’re still undersized for cooling. When they’ve corroded, they’re unreachable. Most 1968 Rohnert Park homes need new flex duct or sheet metal run through the attic or crawlspace before AC can work properly. Call (844) 560-6978 and we’ll assess your specific layout.
Decades of operation in Rohnert Park’s cool, damp climate cause predictable wear. Rust and sediment accumulate on burner assemblies. Ignitors crack from repeated thermal cycling. Gas valves develop internal corrosion that affects flow regulation. These components have finite lifespans, and on a 1970s furnace they’ve all exceeded their design limits. We can keep replacing parts, but at some point the repair frequency and cost exceed the value of the unit. When we service your system, we’ll give you an honest assessment of whether another repair is worthwhile or if replacement makes more financial sense. Estimates are free.
We install and service equipment from nine major brands: Carrier, Trane, Lennox, Goodman, Rheem, York, Daikin, Bryant, and American Standard. In Rohnert Park specifically, we recommend Trane and Lennox for homeowners wanting long-term reliability, and Goodman for cost-effective replacements in rental properties or homes with planned future sales. We match the system to your ductwork capacity, your budget, and how long you plan to stay in the home. Call (844) 560-6978 to discuss which brand fits your situation.
Yes. Annual tune-ups are especially important here because the marine air carries moisture and salt that accelerate corrosion inside your furnace. A yearly inspection catches heat exchanger cracks, burner rust, and airflow restrictions before they cause failures or safety hazards. For homes with original 1960s–1970s ductwork, the tune-up also reveals whether your distribution system is degrading. We schedule tune-ups before the heating season begins, typically September through November. Call (844) 560-6978 to book yours.
Sometimes, but we need to inspect first. Crawlspace ductwork in 1964 Rohnert Park homes is often galvanized steel that’s corroded or disconnected at the seams. If the ducts are structurally intact and properly sized, we can seal and insulate them for cooling use. More commonly, we find they’re undersized for modern AC airflow requirements or too degraded to pressurize. In those cases, we recommend new flex duct or sheet metal properly engineered for your cooling load. We’ll show you what we find and explain your options with actual numbers. Call (844) 560-6978 for a free evaluation.
