We’ve been driving to Mountain View from our San Jose base for nearly two decades, and we know the difference between a quick capacitor swap on a Lennox unit in Old Mountain View and a full system redesign in a Cuesta Park ranch with crushed galvanized ducts. Mountain View’s housing stock is unique in Silicon Valley: 1950s–1970s ranches with no original central cooling, an unusually high concentration of mobile home parks, and now a wave of all-electric new construction under the city’s reach code. That mix means no two jobs are the same, and cookie-cutter solutions fail.
Our AC Repair & Installation team handles everything from emergency refrigerant recharges during October Diablo wind events to full heat pump conversions for homeowners complying with Mountain View’s natural gas ban. Owner Marcus Feldman still manages jobs in the field, so the person quoting your project is the same person making sure the install passes inspection.
Why Crestview Heating & Air California Is Mountain View’s Preferred AC Repair & Installation Company
Mountain View customers have left us enough reviews to build a 4.8-star average across 250+ total ratings, and we hear the same feedback repeatedly: they want someone who shows up when promised, explains the actual problem, and doesn’t try to sell equipment they don’t need. Marcus Feldman answers directly to every customer because he’s both owner and Service Manager. There’s no franchise call center, no dispatched subcontractor, no account manager who disappears after the sale.
Our familiarity with Mountain View’s specific conditions saves customers money and headaches. We know which streets west of Castro sit on expansive clay soil that shifts ductwork in crawlspaces. We know the mobile home parks along El Camino Real require manufacturer-specific equipment and different permit paths than site-built homes. And we know the Googleplex-area tech workers in 94043 want app-connected zoning and will ask detailed questions about SEER2 ratings and HSPF performance before signing off on any install.
Response time matters when an autumn Diablo wind pushes temperatures into the 90s and your 1960s ranch has never had AC. We prioritize Mountain View emergency calls and keep common parts stocked for faster turnaround on repairs.
Our AC Repair & Installation Services in Mountain View
AC Repair
Most Mountain View AC repair calls we get are capacitor failures, compressor electrical issues, or refrigerant leaks in systems that sat unused through the mild summer and then got slammed by a sudden heat spike. A typical repair in Mountain View runs $175–$765. We service Trane, Lennox, Goodman, Rheem, and five other major brands, so we don’t need to order obscure parts or tell you “we don’t work on that.” If your system is blowing warm air or not cycling on at all, we’ll diagnose it upfront and give you a fixed quote before touching anything.
AC Installation
New AC installation in Mountain View costs $4,130–$8,850, with the wide range reflecting whether we’re connecting to existing ductwork or building from scratch. Many Cuesta Park and Rex Manor ranches were built with gas floor furnaces and no ducts at all, so a “simple” install becomes a full ducted system design. For homes that can’t accommodate ductwork, or for homeowners who want zone-by-zone control, we install ductless mini-splits. Mountain View’s building electrification reach code bans natural gas in new construction and major renovations, which is driving far more heat pump and mini-split installs here than in neighboring Sunnyvale or Santa Clara. Tech workers around the Googleplex especially want all-electric, app-connected systems, and we spec those regularly.
AC Replacement
Replacing an old AC in Mountain View often uncovers problems the original installer ignored. We see this constantly in ranch homes near Gemello and west of Castro: the existing galvanized ducts are crushed, disconnected, or leaking so badly they fail Title 24 duct leakage testing. What looks like a straightforward swap turns into a full duct replacement once the HERS rater shows up. We set expectations around this upfront so you’re not surprised mid-project. If your furnace is also gas-fired, we’ll walk you through heat pump options that comply with Mountain View’s reach code and take advantage of the mild winters that make cold-climate heat pump performance penalties irrelevant here.
Refrigerant Recharge
Low refrigerant means a leak, period, and in Mountain View’s older systems that often means R-22, which is now banned from production and increasingly expensive to source. We locate the actual leak rather than just topping off, because pumping refrigerant into a leaking system is throwing money away. For homes near the Bay with persistent marine layer moisture, we also check for corrosion on outdoor coils that can cause micro-leaks over time. A proper recharge with leak repair typically falls in the $175–$765 repair range.

Trusted Brands We Service in Mountain View
We stock parts and have factory-trained experience across nine major brands: Carrier, Trane, Lennox, Goodman, Rheem, York, Daikin, Bryant, and American Standard. For Mountain View customers, that means faster repairs without waiting for special orders. Goodman and Rheem parts move particularly fast here because those brands were common in the area’s 1980s–1990s construction boom. Trane and Lennox systems dominate the newer all-electric builds near the Googleplex, and we spec those for customers who want premium efficiency and smart-home integration. Whether you need a quick capacitor on a 15-year-old Goodman or a full Trane variable-speed heat pump install, we don’t turn jobs away based on brand.
Common AC Repair & Installation Problems We See in Mountain View Homes
- Failed Title 24 duct leakage tests in 1950s–1970s ranches. The oversized gas furnaces in Cuesta Park and Rex Manor homes were connected to undersized, un-insulated galvanized ducts that now leak 30–40% of conditioned air. A furnace-to-heat-pump swap routinely becomes a full duct replacement once testing begins.
- Builder-grade equipment in master-planned homes with no insulation. Newer construction sometimes cuts corners on garage door insulation and attic sealing, creating temperature swings that strain undersized HVAC systems and drive up energy bills.
- Emergency calls during Diablo wind events. Mountain View’s marine layer keeps most summers mild, but October hot snaps can push temperatures into the 90s within hours. Homes that never needed AC suddenly become unlivable, and our emergency line sees surges of calls from neighborhoods like Gemello and the mobile home parks along El Camino.
- R-22 phase-out hitting older systems hard. Many Mountain View ranches still run original AC units from the 1980s or 1990s. When these need refrigerant, the cost of scarce R-22 often makes replacement the smarter financial choice, especially with heat pump rebates available for all-electric upgrades.
Pricing for AC Repair & Installation in Mountain View, CA
We believe in upfront numbers, not vague “call for pricing” deflections. Here’s what AC work actually costs in Mountain View’s market:
| Service | Price Range |
|---|---|
| AC Repair | $175–$765 |
| AC Installation | $4,130–$8,850 |
| Tune-Up / Maintenance | $95–$235 |
| Furnace Repair (if bundled with AC work) | $175–$825 |
Several factors push costs toward the higher end: homes with no existing ductwork, failed Title 24 tests requiring full duct replacement, electrical panel upgrades for heat pump conversions, and smart thermostat integration with multi-zone controls. The mild Bay climate does work in your favor, though. Mountain View’s minimal heating loads mean you don’t need oversized equipment, and cold-climate heat pumps perform efficiently here without auxiliary heat strips that add cost.

Mountain View’s Electrification Reach Code: What Homeowners Need to Know
Mountain View’s city-adopted building electrification reach codes ban natural gas in new construction and major renovations, which has reshaped the local HVAC market in ways you won’t see in Sunnyvale or Santa Clara. The demand isn’t just regulatory, it’s cultural. The tech-worker clientele concentrated around the Googleplex actively researches equipment specs, expects app-connected zoning, and will pay premium prices for all-electric, low-carbon systems.
We replaced a failed gas furnace with a Mitsubishi hyper-heat mini-split in a ranch home on Miramonte Avenue near Cuesta Park. The original galvanized ducts failed Title 24 leakage testing, so we installed a fully ductless system with three wall-mounted heads and Wi-Fi-controlled zoning. The homeowner, a Google engineer, wanted all-electric to comply with the city’s reach code and now monitors the system via their phone. This is increasingly typical in Mountain View, and it’s why we train regularly on heat pump technology and smart-home integration that would be overkill in most other markets.

FAQs — AC Repair & Installation in Mountain View
Yes, replacing an AC unit in Mountain View requires a building permit from the city’s Community Development Department, and if you’re converting from gas to electric, you’ll also need electrical plan review. The permit process typically adds 2–5 business days before work can begin, though we handle all paperwork and scheduling as part of our service. Call (844) 560-6978 and we’ll walk you through what’s needed for your specific property.
A ductless mini-split heat pump is usually the best path for Mountain View ranches with no existing ductwork and gas floor furnaces. These systems avoid the cost and disruption of installing ducts in crawlspaces, comply with the city’s natural gas ban, and provide both heating and cooling with zone-by-zone control. We’ve installed dozens of these in Cuesta Park and Rex Manor, often with Wi-Fi-connected heads that let homeowners monitor energy use by room. Call for a free assessment of your specific layout.
A smart thermostat upgrade with professional installation typically adds $250–$450 to your project, depending on wiring complexity and whether you want multi-zone control. Many Mountain View customers, especially near the Googleplex, opt for thermostats with app-based scheduling and energy reporting. We can integrate these with Trane, Lennox, and other systems during installation or retrofit them to existing equipment. Call (844) 560-6978 for an exact quote based on your current wiring.
We don’t install garage doors or insulation directly, but we regularly coordinate with local contractors on attached garage projects because uninsulated garages create thermal loads that strain your main HVAC system. If you’re in a master-planned Mountain View home with a builder-grade garage door, upgrading the door’s R-value and sealing the garage-to-house envelope often reduces your AC runtime significantly. We can assess the HVAC impact and refer you to insulation specialists we’ve worked with in 94040 and 94041. Call to schedule a whole-home energy evaluation.
R-22 is no longer manufactured and existing stock is extremely limited and expensive, but reclaimed R-22 is still technically available for servicing older systems. In practice, a recharge with R-22 often costs nearly as much as a down payment on a new heat pump, especially when you factor in Mountain View’s available electrification rebates. We recommend evaluating replacement for any R-22 system that needs more than a minor top-off. Call (844) 560-6978 for a free comparison of repair versus replacement costs.
