We’re Crestview Heating & Air California, and we’ve been driving out to San Rafael from our San Jose base for years. We know this valley runs hot — genuinely hot — while the rest of Marin stays cool. That 15–20°F difference between San Rafael and Sausalito isn’t a trivia fact; it’s why your AC failed on a 94°F Saturday afternoon when your cousin in Tiburon didn’t even own one. Our AC Repair & Installation team handles everything from emergency compressor repairs in Terra Linda to full retrofits in Gerstle Park homes built before World War II. Marcus Feldman, our owner and Service Manager, still runs calls personally. We’ve got 19 years in this trade and 250+ reviews averaging 4.8 stars. When your system quits, you need someone who shows up, diagnoses it fast, and fixes it without the runaround.

Our AC Repair & Installation Services in San Rafael
AC Repair
San Rafael’s mid-90s summer afternoons push window units and aging systems past their limits. We see compressor burnout regularly — especially in Terra Linda homes where residents cranked portable ACs hard during September heat waves. Our AC repair calls in San Rafael range from $175–$765, with most falling in the $250–$450 band for capacitor replacements, contactor swaps, and refrigerant leaks. We stock common parts for Trane, Lennox, Goodman, and Rheem to avoid delays. If your system died on a Friday evening, call (844) 560-6978. Emergency service is available.
AC Installation
Here’s where San Rafael gets interesting. Many Terra Linda homeowners calling for “central AC installation” don’t realize their 1960s slab-foundation ranch has zero ductwork. We’ve arrived at dozens of identical floor plans throughout 94903 expecting a standard swap-out and found a full mini-split design job instead. AC installation in San Rafael runs $4,130–$8,850 for central systems, but ductless mini-splits often land in the $3,500–$7,500 range — sometimes the better fit for postwar slab homes with no crawlspace access. We arrived at a 1960s ranch home on Las Colindas Road in Terra Linda expecting a straightforward central AC swap, but the slab foundation had zero ductwork. We installed a five-zone Daikin mini-split system, routing linesets through the attic to preserve the low-pitch roofline, and upgraded the furnace area to MERV-13 filtration for wildfire smoke. Nearly two decades of HVAC experience means we’ve done this exact retrofit before.
AC Replacement
Replacement isn’t just “new for old” in San Rafael. The 1950s–60s Terra Linda tract development was built with no central air conditioning, under the assumption that Bay Area climates never warranted it. That valley-heat/no-AC mismatch creates a retrofit demand in San Rafael that simply does not exist at the same scale anywhere else in Marin County. When we replace a system in 94903, we’re often designing from scratch — sizing for actual cooling load, not just swapping tonnage. Older downtown and Gerstle Park neighborhoods in 94901 have pre-war Craftsman and Victorian stock with cramped crawlspaces and knob-and-tube wiring that complicates modern air-handler installations. We assess electrical capacity, space constraints, and your actual usage before recommending equipment.
Refrigerant Recharge & Compressor Repair
Low refrigerant means a leak, period. We don’t just top off and leave. In San Rafael’s dry summer heat, refrigerant leaks force compressors to overwork, and that $175–$765 repair can escalate to full compressor replacement if ignored. Compressor repair specifically runs toward the higher end of our range, sometimes exceeding $650 for major rebuilds. We use electronic leak detection and nitrogen pressure testing to find the source — not guesswork. Fall Diablo wind events also funnel wildfire smoke from Sonoma County directly into the valley, driving growing demand for MERV-13 or higher filtration retrofits on existing HVAC systems. If your compressor’s struggling, we’ll tell you honestly whether repair or replacement makes financial sense.

Trusted Brands We Service in San Rafael
We maintain active training and parts relationships with Carrier, Trane, Lennox, Goodman, Rheem, York, Daikin, Bryant, and American Standard. For San Rafael customers, that means faster turnaround on repairs — we don’t need to special-order a Lennox contactor or a Goodman capacitor from a warehouse three counties away. Trane and Rheem systems are particularly common in the 1980s–90s additions we see around Lucas Valley-Marinwood and Kentfield. Goodman and Lennox dominate newer construction. Daikin mini-splits have become our go-to recommendation for ductless retrofits in Terra Linda’s slab ranch homes. Whatever’s in your garage, basement closet, or attic — we’ve worked on it, and we’ve got the factory training to prove it.
Common AC Repair & Installation Problems We See in San Rafael Homes
- Knob-and-tube wiring in pre-war homes near Gerstle Park complicates new air handler installs. We regularly find original electrical systems in 94901 that can’t handle modern HVAC loads. The electrical rewiring has to happen before we touch the air handler, adding time and cost that homeowners in newer neighborhoods never face.
- Postwar slab foundations in Terra Linda lack crawlspace access, making ducted mini-split conversions the only viable retrofit option. Central AC assumes ducts. No ducts, no central — unless you’re tearing into walls and ceilings. Most Terra Linda homeowners choose ductless once they understand the alternative.
- High-demand summer afternoons in the low-to-mid 90s°F overwhelm older window units or undersized portable ACs. We’ve responded to emergency compressor burnout calls in 94903 where a 10,000 BTU portable unit ran 14 hours straight trying to cool 1,200 square feet. The math doesn’t work, and the equipment pays the price.
- Wildfire smoke infiltration during fall Diablo winds degrades standard filters and stresses systems. MERV-13 upgrades are increasingly standard on our San Rafael installs — not an upsell, but a response to real air quality events that coastal Marin doesn’t experience with the same intensity.
Pricing for AC Repair & Installation in San Rafael, CA
Here’s what AC work actually costs in San Rafael’s market. These are real ranges based on jobs we’ve completed in 94901, 94903, and surrounding ZIPs:
| Service | Price Range |
|---|---|
| AC Repair | $150–$650 |
| AC Installation | $3,500–$7,500 |
| Tune-Up | $80–$200 |
What moves you within these ranges? For repairs, it’s parts — a capacitor swap runs lower, a compressor replacement hits the top. For installation, it’s equipment size, brand tier, and whether we’re running new linesets through an attic or a simple swap on existing ductwork. The Terra Linda mini-split we installed on Las Colindas Road? That landed mid-range because five zones and MERV-13 filtration added complexity, but no ductwork demolition was needed. We provide upfront pricing before any work begins. Estimates are free. Call (844) 560-6978 to schedule.

FAQs — AC Repair & Installation in San Rafael
You can get cooling, but true central AC requires ducts. Most Terra Linda slab ranch homes were built without them. We typically recommend ductless mini-split systems instead — they provide zoned cooling without tearing into walls. We installed a five-zone Daikin system in a Las Colindas Road home that had zero existing ductwork. Call (844) 560-6978 and we’ll assess your specific layout.
For a 1,500 square foot home in San Rafael, expect $3,500–$7,500 depending on equipment type and existing infrastructure. A ducted central system on existing ducts lands toward the lower end. A full ductless mini-split retrofit in a Terra Linda slab home typically runs mid-range to higher. The exact quote requires a site visit — estimates are free, and we provide upfront pricing before any work begins.
Freezing on hot days usually means restricted airflow or low refrigerant. In San Rafael, we see this when homeowners set thermostats extremely low during peak heat, causing evaporator coils to drop below 32°F. Dirty filters compound the problem, especially during wildfire smoke events when systems run harder. Turn the system off, check your filter, and call us at (844) 560-6978 if it refreezes — running it frozen damages the compressor.
Yes — MERV-13 or higher filtration makes a measurable difference during fall Diablo wind events that funnel Sonoma County wildfire smoke into San Rafael’s valley. Standard fiberglass filters won’t capture fine particulates. We upgrade existing systems and specify MERV-13 on new installs in San Rafael specifically because of this localized air quality pattern. Call for a filter compatibility check — some older systems need airflow modifications to handle denser media.
Not without electrical upgrades first. Knob-and-tube wiring in Gerstle Park and downtown San Rafael’s pre-war homes can’t safely handle modern HVAC loads. We partner with licensed electricians for the rewiring phase, then return for the HVAC installation. We’ve managed this sequence multiple times in 94901. The combined project takes longer but protects your home’s safety and your system’s performance. Call (844) 560-6978 to discuss timing and coordination.
