HVAC Installation & Repairs in Palo Alto, California

Three things above all: the system type, your home’s size, and its age. Palo Alto has everything from century-old Craftsman homes with no ducts to modern rebuilds — and older properties often need electrical upgrades or custom duct routing that we spot at the free assessment, not mid-project. You receive an itemized quote with no hidden fees before anything is scheduled. Call (408) 733-2000 to book your assessment.

Typically under a week: assessment within a day or two, then installation once you approve the quote. The hands-on work is quick — 4–8 hours for a central AC replacement, 3–6 hours per zone for a mini split, 2–3 days when new air conditioning ductwork is involved. Permits are processed in parallel so paperwork doesn’t slow the schedule.

It’s worth a serious look — Palo Alto actively encourages electrification, and heat pumps handle both heating and cooling in one system. Ductless heat pump mini splits reach 20–27 SEER2 and avoid the 20–30% of energy ducted systems can lose through ducts; ducted options at 15–18 SEER2 (California’s current minimum for most new AC installations is 15.2 SEER2) suit homes with existing ductwork. Electrification rebates can meaningfully cut the price. Call (408) 733-2000 and we’ll compare a heat pump against a conventional system for your home.

Usually yes — Palo Alto sits inside our core coverage, and same-day slots are typically available, especially for morning callers. Trucks carry the components behind most failures (capacitors, contactors, igniters, thermostats), so many repairs are completed on the first visit. Call (408) 733-2000 and the dispatcher will confirm today’s earliest arrival for your address.

“Still runs” and “runs well” are different things. Past 15 years, efficiency drops, parts become scarce, and heat exchanger risks grow — while replacement on your schedule always beats replacement during a January breakdown. If any repair quote passes 50% of a new unit’s cost, that’s the tipping point; a modern high-efficiency system or heat pump also unlocks California rebates. Call (408) 733-2000 for an honest assessment with real numbers.

Book an AC tune-up in spring and a heating check in fall, and change the air filter every 1–3 months. Palo Alto’s leafy streets mean outdoor condensers collect oak leaves and pollen steadily — a quick monthly check of the unit keeps airflow clear. During wildfire smoke events, upgrade to a higher-MERV filter and replace it more often; it protects both your lungs and the blower motor.
