HVAC Solutions Built for Palo Alto's Diverse Housing Stock

Palo Alto's signature mid-century Eichlers and classic Craftsman homes demand specialized HVAC approaches. We handle radiant slab retrofits, tight crawlspace installations, and discreet condenser placement that respects neighborhood character—whether you need air conditioner repair or a complete system installation.

Air Conditioner Repair

Fast AC repair service to restore your cooling when summer heat spikes push older systems to their limit. We diagnose and repair all makes and models, including units in tight Eichler attics and constrained Professorville crawlspaces where access matters.

Furnace Repair

Emergency furnace repair keeps your home warm during winter cold snaps when radiant slab systems struggle. Our EPA Section 608-certified technicians service gas, electric, and hybrid systems in homes across Downtown, Old Palo Alto, and College Terrace.

Air Conditioner Installation

Replace aging AC units with properly sized, high-efficiency systems that fit your home's unique layout. From Eichler retrofits to Craftsman homes, we route equipment discreetly to respect neighborhood character and minimize roof or exterior visibility.

Complete HVAC System Installation

Install new heating and cooling systems engineered for Palo Alto's Mediterranean climate and your home's specific construction. Proper sizing, balanced return air design, and smart thermostat integration ensure long-term efficiency and comfort without costly upgrades later.

Indoor Air Quality & Filtration

Reduce dust and allergens with correctly sized return air grilles, advanced filtration, and air duct cleaning. Undersized returns starve your system and reduce capacity—we ensure each bedroom has proper air circulation to improve indoor air quality.

Preventive HVAC Maintenance

Seasonal tune-ups extend equipment life, maintain warranty compliance, and catch minor issues before they become expensive repairs. Regular maintenance is especially valuable for heat pump owners, who can avoid costly emergency heat operation during cold weather.

Air Duct Cleaning

Professional duct cleaning removes years of accumulated dust, debris, and allergens from your HVAC system. Cleaner ducts improve airflow efficiency and indoor air quality, particularly important in older Palo Alto homes where original ductwork may harbor buildup.

Heat Pump Installation & Service

Install efficient heat pump systems for year-round heating and cooling in one unit, ideal for Palo Alto's mild winters and moderate summers. If your system shows constant 'EM HEAT' warnings, our technicians diagnose why—emergency heat costs 2–3 times more to run.

Why Palo Alto Homeowners Choose HVAC of Palo Alto

We understand Palo Alto's climate swings—summer heat spikes that stress older cooling systems, mild winters where heat pumps outperform furnaces, and coastal winds affecting outdoor unit placement. Our technicians diagnose root causes, not symptoms, saving you money on repairs and energy bills.

Our technician diagnosed a failing compressor versus a refrigerant leak—saved us thousands on unnecessary replacement. They explained the whole system and walked us through energy-efficient upgrade options for our Eichler.

AC died during a 95-degree spike. They arrived same day, found a duct leak that had been costing us 20% in wasted cooling, sealed everything properly, and had the system running efficiently by evening.

We have a 1958 Craftsman with knob-and-tube wiring and a crawlspace the size of a closet. They figured out how to install a new furnace without tearing into the walls or violating our neighborhood conservation guidelines.

HVAC Questions Answered

We recommend professional maintenance twice yearly in Palo Alto—once in spring before cooling season and again in fall to prepare for mild but wet winters. Regular service catches refrigerant leaks, cleans condenser coils, and ensures your system handles late-summer heat spikes efficiently.
A Manual J load calculation is the industry standard method for sizing HVAC systems based on your home's square footage, insulation, window orientation, and local climate. In Palo Alto, many older Eichlers and Craftsman homes have inadequate attic insulation, which significantly increases heating and cooling loads. Proper sizing prevents short-cycling and ensures consistent comfort.
Most systems last 15–20 years with proper maintenance. If your unit is over 15 years old, frequently needs repair, or struggles during Palo Alto's rare cold snaps or heat events, replacement becomes cost-effective. Newer two-stage systems also provide better dehumidification and quieter operation.
Yes. All our repairs include warranty coverage on both parts and labor. We stand behind our workmanship and use quality components so you can rely on your system when you need it most.
A heat pump reverses refrigerant flow to provide both heating and cooling from a single system. In Palo Alto's mild winters and moderate summers, heat pumps are highly efficient and eliminate the need for a separate furnace. They pair well with smart thermostats to optimize variable time-of-use electricity rates.
Change air filters monthly, especially if you live near the Baylands or during wildfire season. Seal ductwork to prevent leakage into crawlspaces and attics, use MERV 13 filters, and consider air duct cleaning every 3–5 years. Proper humidity control (40–60%) also reduces allergens and mold growth.
Refrigerant should not escape from a sealed system. Loss indicates a leak—often at solder joints, connection fittings, or the condenser coil. We locate and repair the source, then recharge the system. Ignoring leaks reduces cooling capacity and wastes energy.
