AC Installation & Repairs in Palo Alto, CA

In most cases, yes. If you call earlier in the day, we can usually get a technician out to your Palo Alto home before evening. Response times tighten up during heatwaves, so it’s worth calling as soon as you notice the system struggling rather than waiting it out. Reach us at (408) 733-2000 to check what’s available today.

Palo Alto has plenty of older, character-filled homes that were never built with central ductwork, and ductless mini splits tend to be the go-to solution here. They install without tearing into walls or ceilings and let you target specific rooms rather than cooling the whole house uniformly. We’ll take a look at your floor plan and figure out the number of zones that makes sense.

It depends heavily on the system you choose, how many rooms or zones need coverage, and whether existing ductwork can be reused as-is. Rather than throw out a broad estimate that might not apply to your house, we come out, look at the space, and hand you a written, itemized quote so there’s no guesswork.

Less than most people expect. A single central AC swap is usually wrapped up in 4–8 hours, and a one-zone mini split can often be done in half a day. Larger multi-zone jobs or ones that require running new ductwork stretch to 2–3 days. We’ll walk you through the plan before anything starts so you know what to expect.

A good gut check: if the unit is over a decade old, or the repair quote is inching toward half the price of a new system, replacement usually wins out over time through lower energy bills and fewer surprise breakdowns. We’ll lay out the real numbers for both options so the decision isn’t a guessing game.
