We’ve been driving to Rohnert Park from our San Jose base for nearly two decades, and we’ve learned this planned city inside out. The uniform tract phases, the slab-on-grade construction, the way the Petaluma Gap sweeps cool marine air through town until it doesn’t anymore. When a heat dome settles over Sonoma County, Rohnert Park homeowners call us because their 1960s and 70s houses were never built for cooling, and the retrofit challenges are real.
Marcus Feldman, our owner and Service Manager, still runs calls personally. That means when you book with Crestview Heating & Air California, you’re getting 19 years of HVAC experience directed by someone with actual ownership stake in the outcome, not a dispatched contractor you’ve never met.
Why Crestview Heating & Air California Is Rohnert Park’s Preferred AC Repair & Installation Company
Local reputation built on Rohnert Park’s actual housing stock. We’ve retrofitted enough 1960s slab homes in Rohnert Park to know where the buried ducts are, which phases used galvanized flex, and which neighborhoods near Sonoma State University sit in the wind corridor that accelerates coil corrosion. That specificity matters when a technician walks into your crawlspace and knows what to look for.
250+ customers who left reviews agree: our 4.8-star average reflects real outcomes on real jobs, including dozens of Rohnert Park installations where duct replacement was the make-or-break factor. We don’t cherry-pick testimonials. The volume speaks for itself.
Response time that respects your schedule. We route Rohnert Park calls directly from our San Jose dispatch, typically arriving same-day for repairs and scheduling installations within a week during peak season. Emergency HVAC service is available when systems fail outside normal hours.
Owner-managed, not outsourced. Marcus Feldman holds the title of Service Manager, so accountability doesn’t stop at the office door. On complex Rohnert Park retrofits, especially slab-embedded duct replacements, that direct involvement prevents the miscommunications that derail projects.
Our AC Repair & Installation Services in Rohnert Park
AC Repair
Most Rohnert Park repair calls we handle involve capacitor failure, refrigerant leaks, or compressor issues accelerated by salt-air corrosion near the Petaluma Gap. A typical AC repair in Rohnert Park runs $150–$650. We stock capacitors and contactors for Trane, Lennox, Goodman, and Rheem units to avoid ordering delays. If your condenser coils are corroded from years of marine exposure, we’ll show you the damage and explain whether repair or replacement makes financial sense.

AC Installation
New AC installation in Rohnert Park is rarely plug-and-play. The city’s planned-city architecture means most homes were built with heating-only ductwork, often embedded in concrete slabs or sized too small for cooling airflow. We recently retrofitted a 1964 slab-home on Old Redwood Highway where the original galvanized duct was buried in the slab. We replaced the entire distribution system with new flex duct in the attic, installing a 3-ton Carrier unit sized for the home’s actual cooling load. Full AC installation with duct replacement in Rohnert Park typically falls in the $3,500–$7,500 range depending on system size and ductwork complexity.

AC Replacement
Replacing an existing AC in Rohnert Park sometimes reveals the real problem: the old unit failed because the ductwork couldn’t move enough air. We see this constantly in the two-story tracts near Rohnert Park’s eastern neighborhoods, where original flex ducts from the 1970s have collapsed or disconnected. Our replacement quotes include airflow testing. If your ducts are the culprit, we’ll tell you before installing new equipment on top of a failing distribution system.

Refrigerant Recharge
R-22 systems are still common in Rohnert Park’s older phases, and refrigerant leaks often trace to corroded line sets or outdoor coil damage from salt-laden marine air. We recharge systems only after leak detection, because pumping refrigerant into a leaking system wastes your money. If your R-22 unit is leaking at multiple points, we’ll explain why replacement with a modern R-410A system may cost less over five years than repeated recharges and repairs.

Duct Replacement
This is the service that defines Rohnert Park HVAC work. In the city’s earliest slab-construction phases from the 1960s–70s, heating ducts were often poured directly into the concrete foundation, making AC retrofits impossible without full attic or crawlspace duct replacement. Even homes with attic flex ducts often have 50-year-old material that’s degraded, undersized, or rodent-damaged. We design and install complete duct systems sized for cooling loads, not just heating.

Trusted Brands We Service in Rohnert Park
Your system, our specialty. We maintain factory-trained compatibility across nine major brands, and for Rohnert Park customers we emphasize the four we encounter most in local housing stock: Trane, Lennox, Goodman, and Rheem. These brands dominate the replacement market in Sonoma County, and we stock common parts to minimize wait times. Whether you need a capacitor for a 15-year-old Goodman or a full Lennox variable-speed installation, our San Jose warehouse carries inventory that lets us respond without cross-county parts runs. That matters when you’re waiting for AC during a September heat event.
Common AC Repair & Installation Problems We See in Rohnert Park Homes
- Slab-embedded ducts from the 1960s–70s degrade or collapse, requiring complete replacement rather than simple patchwork. We’ve opened crawlspaces in the original Rohnert Park tracts and found galvanized ductwork literally disintegrated inside the concrete. There is no repair option. The entire distribution system must be rebuilt overhead.
- Heating-only ductwork is undersized for cooling airflow, leading to inadequate cooling and frozen coils unless ducts are resized. Rohnert Park’s uniform tract design used the same duct layouts across thousands of homes, all optimized for furnace output. Add an AC coil to that restricted airflow and you get ice, noise, and premature compressor failure.
- Salt-laden marine air from the Petaluma Gap accelerates corrosion on outdoor condenser coils and electrical connections, shortening equipment lifespan. Units in exposed locations near the western edge of Rohnert Park can show coil damage years earlier than identical systems in sheltered Santa Rosa neighborhoods. We recommend corrosion-resistant coatings and more frequent maintenance for these installations.
- Original flex ducts in 1970s attic spaces have exceeded their design life, becoming brittle, collapsing at sag points, or losing insulation value. Homeowners assume their “attic ducts are fine” until we camera-inspect and show them the disconnects and compression points that explain why the master bedroom never cools.

FAQs — AC Repair & Installation in Rohnert Park
Yes. Homes with ducts buried in the concrete slab require complete attic or crawlspace duct replacement before AC can be installed, since slab ducts cannot be modified or repaired. This is common in Rohnert Park’s 1960s–70s construction phases. We factor duct replacement into every slab-home quote so there are no mid-project surprises. Call (844) 560-6978 for a free assessment of your duct configuration.
The persistent onshore airflow through the Petaluma Gap carries salt-laden humidity that corrodes outdoor condenser coils and electrical connections faster than in sheltered inland locations. We’ve replaced coils in Rohnert Park that showed corrosion damage typical of units five years older in Santa Rosa. Annual maintenance with coil cleaning and connection inspection extends equipment life measurably in this environment.
Probably not. Original flex ducts from the 1960s–70s are typically undersized for cooling airflow and may be degraded, collapsed, or disconnected after 50+ years. We test airflow and inspect with cameras before recommending any AC installation. If your ducts can’t move the required CFM, we’ll show you the numbers and quote replacement sized for your actual cooling load.
We repair and install nine major brands: Carrier, Trane, Lennox, Goodman, Rheem, York, Daikin, Bryant, and American Standard. In Rohnert Park, we most commonly service Trane, Lennox, Goodman, and Rheem units, and stock parts for same-day repair on these brands. If you own a less common system, our factory training still covers it. Call (844) 560-6978 with your model number.
Yes. The City of Rohnert Park requires permits for new AC installations and most replacements, with inspections for electrical, mechanical, and sometimes ductwork modifications. We pull permits as part of our standard installation process and coordinate inspections so you’re not chasing paperwork. This is especially important for slab-duct replacement projects that trigger additional code requirements.
