The short answer
SwiftAir installs central AC, heat pumps, and ductless mini-splits in Los Altos homes, starting with a room-by-room load calculation so the system fits your house. We'll help you weigh a heat pump against a standard AC and confirm which incentives are currently available before you decide.
If your Los Altos home has never had central air, or the system you have is wearing out, a new installation is your chance to get the sizing, ductwork, and equipment right the first time. SwiftAir Conditioning Repair installs central air conditioners, heat pumps, and ductless mini-splits for homes in Los Altos (94024) and throughout Santa Clara County. Our technicians come from San Jose, about 10 miles east, and we plan every installation around your specific house rather than a one-size-fits-all package.
It Starts With Sizing Your Los Altos Home Correctly
An oversized air conditioner cools the house quickly, then shuts off before it removes much moisture. That leaves rooms feeling clammy and puts extra wear on the equipment. An undersized unit runs nonstop on the hottest afternoons and still falls behind. Picking a size by square footage alone often lands in one of those two traps.
We size your system with a load calculation based on how your home actually gains and loses heat. A single-story ranch with big west-facing windows needs something different from a shaded two-story house with a well-insulated attic, even if the floor area is about the same.
- Attic and wall insulation levels
- Window size, type, and which direction each window faces
- Shade from trees, overhangs, and nearby structures
- Ceiling heights, room layout, and how many people use each space
- Condition and size of any existing ductwork
Central AC, Heat Pump, or Ductless Mini-Split
The Santa Clara Valley has a Mediterranean climate, with dry summers and mild, damp winters. In practice, many Los Altos homes need solid cooling for part of the year and only modest heating the rest of it. That's why plenty of homeowners compare a heat pump with a standard central air conditioner. A heat pump is installed much like an AC, but it can also heat the house.
Timing matters too. Under Bay Area Air District rules, natural gas furnaces manufactured from 2029 on must meet a zero-NOx emission standard. That points homeowners toward heat pumps when they replace a furnace after that date. These rules don't make you replace working equipment. They apply only when an existing furnace fails or gets replaced. Still, if your furnace is aging, it's worth thinking about heating and cooling together now.
Ductless mini-splits suit homes without ductwork, room additions, converted garages, and upstairs bedrooms that run warmer than the rest of the house. Each indoor head has its own controls, so you only cool the rooms you're using.
Planning Around Older Homes and Existing Ductwork
Many installations in Los Altos involve houses that were never designed for central air. Before we recommend equipment, we check whether your existing ducts are sized and sealed well enough to carry cooled air. We also look at whether your electrical panel can handle the new load and where an outdoor unit can sit without crowding a bedroom window or a neighbor's property line.
If your ductwork is undersized, leaky, or damaged, we'll show you what we found and explain your options. You may be able to repair sections, replace the ducts, or skip ducts entirely with a ductless system. Installations typically require a permit, and we handle the application and schedule the inspection as part of the job.
Incentives and Tax Credits to Know About
The federal Energy Efficient Home Improvement Credit (25C) covered qualifying heat pumps placed in service before December 31, 2025. It isn't available for installations after that date, so don't count on it when budgeting a new system.
Local programs may still help. Bay Area homeowners can check BayREN and their local clean energy provider for current heat pump and electrification incentives. Amounts and availability change with each funding cycle, so we confirm the current offer before including it in any quote.
What to Expect on Installation Day
Once you've chosen your equipment, we schedule the installation and walk you through the plan beforehand. Most of the work happens outside, in the attic, and wherever the indoor equipment is located. We protect floors and work areas as we go.
- Removal and disposal of any old equipment
- Setting the outdoor unit on a level pad and connecting refrigerant lines
- Installing or connecting the indoor coil, air handler, or mini-split heads
- Electrical connections and thermostat setup
- Testing airflow, refrigerant charge, and temperature at the vents
- A walkthrough of how to operate the system and when to change filters
