HVAC Company in Palo Alto, CA
Dalton Heating & Air handles HVAC repair and installation across Palo Alto, CA, with written pricing before any work starts and a full-year written guarantee on every repair. Most Palo Alto homes were built between the 1950s and 1980s, which means systems often run on older ductwork sized for less demanding summers than we get now. When a system fails here, it’s usually tied to age, deferred maintenance, or a heat load the original equipment was never designed to carry. Call (361) 306-9515 and you’ll get a real person, day or night.
Why Palo Alto Homes Are Different
Palo Alto sits at the northern edge of Silicon Valley, and the housing stock changes character every few blocks. In Professorville and Old Palo Alto, you’ll find century-old homes with crawl spaces, original framing, and retrofitted mechanical closets that squeeze modern air handlers into spaces built for gravity furnaces. South Palo Alto and Midtown lean mid-century, which brings its own set of realities: undersized return ducts, settled slabs, and electrical panels that need attention before a heat pump installation can move forward.
The microclimate matters too. Palo Alto runs cooler than San Jose but warmer than Half Moon Bay, and summer afternoons regularly push into the high 80s and low 90s for stretches that used to be rare here. Homes near the Baylands get damp, salty air that corrodes condenser coils faster than inland units. Homes up in the hills above Page Mill Road deal with steeper grade access and units that run harder because heat rises. Permits go through the City of Palo Alto, and we handle the paperwork and inspection scheduling on installation jobs so homeowners in Barron Park, College Terrace, and Greenmeadow aren’t guessing at the process.
Our Main Palo Alto Services
Three services carry most of our calls in Palo Alto: AC repair through the summer, furnace repair through the winter, and heat pump installation year-round as homeowners replace aging equipment. Each has its own page with local pricing, what to check before calling, and what the job looks like step by step.
AC Repair in Palo Alto
When a Palo Alto AC goes down in August, the house heats up fast, especially in west-facing bedrooms and upstairs rooms in two-story Midtown homes. We diagnose the failed component, put the repair price in writing, and get the system running usually the same visit. Refrigerant leaks, failed capacitors, and frozen evaporator coils are the most common calls we run here. See typical Palo Alto repair costs and what to expect on the AC Repair in Palo Alto page.

Heat Pump Installation in Palo Alto
A heat pump installation in Palo Alto replaces both heating and cooling with one electric system, which pencils out well for homes that no longer want to run a gas furnace. We size the equipment to the house, confirm the electrical panel can carry the load, and set a written install date before any work begins. Older Palo Alto neighborhoods often need duct adjustments or a panel upgrade to do this right. Details on equipment, rebates, and timelines are on the Heat Pump Installation in Palo Alto page.

Furnace Repair in Palo Alto
Palo Alto winters are mild, but December and January nights drop into the 30s, and a failed furnace is a real problem in a house with single-pane windows and no wall insulation. Most furnace repairs here come down to ignitors, flame sensors, gas valves, or blower motors, and we stock the common parts for Carrier, Trane, Lennox, Goodman, Rheem, York, Daikin, Bryant, and American Standard systems. Read the Furnace Repair in Palo Alto page for what these repairs cost and what we cover in writing.

Pricing for HVAC Company in Palo Alto, CA
| Service | Typical range in Palo Alto |

What pushes a Palo Alto job toward the top of those ranges is access: crawl space work in an older Professorville home, a condenser on a hillside pad above Page Mill, or a panel that has to be brought up to code before new equipment goes in. Whatever the number, it’s in writing before we start, and that’s not a courtesy, it’s the way we work.
