Heating and Cooling Services for Palo Alto Homes
Most calls we get from Palo Alto fall into a few categories: a system that won't turn on, one that runs but doesn't heat or cool well, or one that's getting noisy, short-cycling, or driving up energy use. We start by finding the actual cause, then explain what we found and what the repair involves before any work begins.
When repair no longer makes sense, we'll tell you why and walk through replacement options that fit your home, your ductwork, and how you actually use your heating and cooling.

How the Local Climate Shapes Your System
The Santa Clara Valley has a Mediterranean climate: dry summers and mild, damp winters. Palo Alto sits closer to the Bay than the inland and southern parts of the valley, which tend to run noticeably hotter in summer. That means many Palo Alto homes need steady, efficient heating through the cool, wet months and cooling that handles occasional hot stretches rather than months of extreme heat.
That pattern matters when choosing equipment. An oversized AC can cycle on and off without properly removing moisture, while an undersized system struggles on the warmest days. A properly sized heat pump often fits this climate well because it handles both mild-weather heating and summer cooling in one system. Ductless mini-splits are a practical option for additions, converted garages, or older homes without existing ductwork.
Furnace Replacement and Bay Area Air District Rules
If you have a natural gas furnace, it helps to know what's coming. Under Bay Area Air District Rule 9-4, natural gas furnaces manufactured from 2029 must meet a zero-NOx emission standard. In practice, that points homeowners toward heat pumps when a furnace is replaced after that date.
These rules don't require you to replace equipment that's working. They apply only when an existing furnace or water heater fails or is replaced. So there's no need to rip out a healthy furnace, but if yours is aging, planning ahead can keep you from making a rushed decision during a breakdown.
On incentives: the federal 25C tax credit covered qualifying heat pumps placed in service before December 31, 2025, and it isn't available for new installations after that date. Bay Area homeowners can still check BayREN and their local clean energy provider for current heat pump and electrification incentives. Amounts and availability change by funding cycle, so we confirm the current offer before including it in a quote.
Maintenance, Ducts, and Indoor Air Quality
Regular HVAC maintenance helps catch small problems, like a weak capacitor, a dirty coil, or a clogged drain line, before they turn into a no-heat or no-cool call. Many homeowners schedule heating checks in the fall before damp weather arrives and cooling checks in spring before the first warm days.
Dry summers can bring dust and, in some years, smoky air. Duct cleaning, better filtration, and other indoor air quality upgrades can help keep the air inside your home cleaner. We'll look at your current setup and recommend only what makes sense for your system and your concerns.
