Fast, Reliable Heat Pump & Mini Split Across Los Altos
Heat pump and mini-split installation in Los Altos typically runs $3,500–$7,500 for a full system, with most retrofit jobs completed in two to three days. We serve all of Los Altos, from the western slopes of 94022 near Foothill College to the flatter neighborhoods of 94024 along El Camino Real, and we carry the Daikin and Rheem inventory to avoid supply delays on most jobs.
We’re Crestview Heating & Air California, and our Heat Pump & Mini Split team knows Los Altos’s housing stock inside out. After 19 years in HVAC, we’ve learned that this city’s 1950s–1970s ranch homes present a specific challenge: they were built for gas furnaces, not modern heat pumps, and the ductwork proves it. Owner Marcus Feldman still manages every job as Service Manager, so when we quote a system for your Covington Road ranch or your multi-zone setup near Grant Park, you’re talking to someone with ownership-level accountability. Call (844) 560-6978 for a free estimate.
Why Crestview Heating & Air California Is Los Altos’s Preferred Heat Pump & Mini Split Company
Our 4.8-star average across 250+ reviews didn’t come from easy jobs. It came from showing up to Los Altos homes where the previous contractor sized the heat pump for “Bay Area average” and the system locked out during the first Diablo wind event. We don’t do average.
Marcus Feldman built Crestview on owner-managed service, not outsourced dispatch. When you call (844) 560-6978, you’re reaching a team where the same person who answers questions also signs off on equipment specs. For Los Altos customers, that means we account for the 6–10°F temperature swing between western 94022 and eastern 94024 before we recommend tonnage. We’ve replaced too many undersized compressors in this city to guess.
Our parts inventory covers Trane, Lennox, Goodman, and Rheem components, so most Los Altos repairs don’t wait on shipping. From emergency calls to full ranch-home retrofits, we handle the full scope.
Our Heat Pump & Mini Split Services in Los Altos
Heat Pump Installation
Los Altos’s ranch homes were never designed for the static pressure of a modern AC coil. The original sheet-metal ductwork in a 1962 home on Magdalena Avenue, for example, might move 700 CFM comfortably for a gas furnace but choke on the 1,200+ CFM a heat pump demands. We start every Los Altos install with a Manual D duct audit. If the trunk is too narrow, we tell you before we quote equipment, not after the third callback. Most full heat pump conversions in Los Altos run $3,500–$7,500, with permits pulled through the City of Los Altos Building Department.
Mini Split Installation
For homes where the ductwork is beyond saving, or for detached workshops that never had ducts to begin with, mini splits are the practical path. We recently retrofitted a multi-zone mini-split system in a 1965 ranch home on Covington Road in 94022, where the owner had three detached workshops requiring dedicated ductless units. The western slope location meant we upsized the compressor from a 3-ton to a 3.5-ton Daikin to handle the higher heat load, and we ran new refrigerant lines through the crawlspace to avoid the patchwork ductwork in the main house. That’s the kind of field-specific sizing Los Altos demands.
Multi-Zone System Design
Los Altos’s partially remodeled ranches often have three decades of duct generations layered together: 1960s trunk-and-branch in the bedrooms, 1990s flex duct in the family-room addition, a newer air handler in the converted garage. No single thermostat can balance that. Multi-zone mini splits let each area call its own temperature, and they eliminate the static pressure mismatches that cause new equipment to short-cycle. We design these systems for real Los Altos floor plans, not catalog assumptions.
Heat Pump Repair
In western 94022, heat pumps sized for “typical Bay Area” weather struggle during Diablo wind events that push temperatures above 100°F, causing capacity lockouts and inadequate cooling. We see this every August. Our repair calls start with a full diagnostic: refrigerant charge, compressor amp draw, and whether the original installer accounted for your specific microclimate. We stock replacement compressors, reversing valves, and control boards for Trane, Lennox, Goodman, and Rheem systems to get Los Altos homes back online fast.
Mini Split Repair
Ductless systems in Los Altos fail differently than ducted ones. Refrigerant leaks at flare connections, failed inverter boards, and clogged condensate pumps are the usual suspects. Because we carry Daikin and Rheem mini-split parts locally, most repairs don’t stretch into a second appointment.

Trusted Brands We Service in Los Altos
Your system, our specialty. Crestview services nine major HVAC brands, and we maintain local parts inventory for Trane, Lennox, Goodman, and Rheem to keep Los Altos jobs moving. That matters when a heat pump fails on a 102°F afternoon in western 94022 and the homeowner needs same-day relief. We’ve also factory-trained on Daikin mini-split systems, which we specify frequently for Los Altos’s multi-zone retrofit work. Whether your equipment is two years old or original to a 1970s ranch, we’ve likely serviced that model before. Nearly two decades of HVAC experience means we’ve encountered virtually every system type, age, and configuration a Los Altos property can present.
Common Heat Pump & Mini Split Problems We See in Los Altos Homes
- Undersized heat pumps failing in western 94022. Contractors who size for flat 94024 conditions install equipment that can’t handle the radiant heat load from the Santa Cruz Mountain slopes. We upsize by half a ton for homes near Foothill College and north of Interstate 280.
- Patchwork duct generations causing static pressure chaos. A 1960s trunk feeding 1990s flex duct creates turbulence that new mini-split systems detect as fault conditions. We map the full duct path before connecting any new equipment.
- Detached workshops with inadequate cooling. Los Altos’s large lots often include metal-roofed outbuildings with roll-up doors and zero insulation. These spaces need dedicated multi-zone mini-splits sized for actual square footage and heat gain, not a spare head from the main house system.
- Original ductwork undersized for heat pump airflow. The 700-CFM trunks common in 1960s Los Altos ranches can’t move the volume a modern heat pump requires. We identify this mismatch during our initial audit and quote the duct modification with the equipment.
Pricing for Heat Pump & Mini Split in Los Altos, CA
We’re straightforward about numbers because Los Altos homeowners are straightforward about expectations. Here’s what we see in this market:

FAQs — Heat Pump & Mini Split in Los Altos
Yes, the City of Los Altos Building Department requires permits for all heat pump and mini-split installations, including electrical and mechanical inspections. We pull permits on every job and coordinate inspections so you don’t manage the paperwork. Call (844) 560-6978 and we’ll walk you through the timeline for your specific project.
Sometimes, but only after a Manual D duct audit confirms your trunk can handle the airflow a heat pump demands. Many Los Altos ranches have 700-CFM trunks that choke on modern equipment, requiring either duct modification or a switch to ductless mini splits. We’ll test your system and give you both options with real numbers.
The microclimate split is real. Western 94022 neighborhoods near Foothill College trap radiant heat from the Santa Cruz Mountain slopes and run 6–10°F warmer on summer afternoons than eastern 94024 near El Camino Real. That temperature difference can shift equipment tonnage requirements by half a ton between homes just a mile apart. We size for your specific location, not a city average.
A single head can work if the workshop is well-insulated and modest in size, but Los Altos’s metal-roofed outbuildings with roll-up doors often need dedicated multi-zone systems sized for actual heat gain. We calculate load based on square footage, insulation R-value, and door type before recommending equipment. Call (844) 560-6978 for a free assessment of your specific space.
We specify Daikin most often for Los Altos multi-zone retrofits because their inverter-driven compressors handle the partial-load conditions common in mild Bay Area winters, and their local parts availability keeps future repairs moving. Rheem and Trane also offer strong multi-zone lines, and we’ll match the brand to your home’s specific layout and your long-term service expectations. Call (844) 560-6978 to discuss which system fits your project.
