Your home becomes a place where every room maintains its perfect temperature without the noise, energy waste, or architectural compromises of traditional systems. No more hot spots in the master bedroom or freezing cold guest rooms that nobody wants to use.
Ductless mini-split systems give you individual control over each zone of your home. You set the temperature for your home office at 72 degrees while keeping the rarely-used formal dining room at 78 degrees. Your energy bills drop because you’re only conditioning the spaces you actually use.
The quiet operation means no more system noise interrupting conversations or sleep. Your home maintains the peaceful atmosphere Atherton residents expect, while every room stays exactly as comfortable as you want it.
We’ve been serving Atherton and Santa Clara County since 1985. What started as a family business under Ramiro’s father continues today with the same commitment to quality service and community relationships.
You’re working with technicians who understand both the technical demands of ductless systems and the service expectations of Atherton homeowners. Our team includes long-term professionals, not rotating temporary staff who disappear after a few months.
We’re actively involved in local community sponsorships because Atherton isn’t just our service area—it’s our home too. When you choose us, you’re supporting a local business that’s invested in this community for the long term.
We start with a thorough assessment of your home’s cooling needs, considering room sizes, sun exposure, usage patterns, and your family’s comfort preferences. Every Atherton home has unique characteristics that affect system performance, and we account for all of them.
Next comes system design and equipment selection. We calculate the exact capacity needed for each zone and recommend the most efficient mini-split configuration for your specific layout. You’ll see transparent pricing upfront—no surprises or hidden fees.
Installation typically takes one to two days depending on the number of zones. We run refrigerant lines between outdoor and indoor units through small holes that won’t disrupt your home’s architecture. Each indoor unit mounts high on the wall where it quietly distributes conditioned air throughout the room. We test everything thoroughly before we leave and walk you through the system operation so you’re completely comfortable with your new comfort solution.

Your ductless air conditioning system includes individual indoor units for each zone, a high-efficiency outdoor condenser, and wireless remote controls for each room. Every component is sized specifically for your home’s needs and installed to manufacturer specifications for optimal performance.
Atherton’s Mediterranean climate is ideal for ductless systems. The mild winters mean your mini-splits can provide efficient heating when needed, while the warm, dry summers showcase their cooling capabilities. Unlike traditional systems that lose energy through leaky ductwork, your conditioned air goes directly where it’s needed.
You also receive comprehensive warranty coverage on both equipment and installation workmanship. We stand behind our work because we’ll be here to service your system for years to come. Many of our clients discover their new ductless system pays for itself through energy savings within a few years, especially when replacing older, inefficient equipment.
Ductless system costs vary based on the number of zones, equipment efficiency ratings, and installation complexity. A single-zone mini-split for one room typically ranges from $3,500 to $6,000 installed, while whole-home multi-zone systems can range from $8,000 to $20,000 depending on your home’s size and specific requirements.
The investment often pays for itself through energy savings, especially if you’re replacing an older, inefficient system or adding cooling to spaces that previously had none. We provide free estimates that break down all costs clearly, so you understand exactly what you’re investing in.
Many Atherton homeowners find the zoned comfort control and energy efficiency make ductless systems more cost-effective than traditional central air, particularly in larger homes where different areas have varying cooling needs.
Yes, modern ductless heat pump systems provide both heating and cooling efficiently. Atherton’s mild climate is actually ideal for heat pump technology because temperatures rarely reach the extremes that challenge system performance.
During summer months, your mini-splits provide quiet, efficient cooling exactly where you need it. In winter, the same units reverse operation to provide heating that’s often more efficient than traditional gas furnaces, especially for maintaining comfortable temperatures in specific rooms or zones.
The year-round functionality means you’re investing in a complete comfort solution, not just air conditioning. Many of our Atherton clients use their ductless systems as their primary heating and cooling, while others use them to supplement existing systems in specific areas like home offices, master suites, or room additions.
Most residential ductless installations in Atherton take one to two days, depending on the number of zones and complexity of the installation. Single-zone systems often install in one day, while whole-home multi-zone systems typically require two days for proper installation and testing.
The process involves mounting indoor units, installing the outdoor condenser, running refrigerant lines between components, and connecting electrical systems. We work efficiently while maintaining the clean, professional standards Atherton homeowners expect.
Unlike traditional central air installation that can disrupt your home for a week or more with ductwork installation, ductless systems integrate into your existing home with minimal disruption. You can typically use most of your home normally during installation, and you’ll have comfortable temperatures as soon as we complete each zone.
Ductless systems are actually ideal for large homes because they provide zoned comfort control that traditional systems can’t match. Instead of trying to maintain one temperature throughout a 4,000 or 6,000 square foot home, you can set different temperatures for different areas based on usage and preferences.
Multi-zone systems can handle homes of any size by installing multiple indoor units connected to appropriately sized outdoor condensers. You might have separate zones for the master suite, main living areas, guest bedrooms, and home office, each with independent temperature control.
This zoned approach is particularly beneficial in Atherton’s custom homes where room sizes, ceiling heights, and sun exposure vary significantly. You’re not wasting energy cooling unused guest rooms or struggling with hot spots in rooms with large windows. Each zone operates independently for maximum comfort and efficiency.
Ductless systems require less maintenance than traditional central air because there’s no ductwork to clean or seal. Basic maintenance includes cleaning or replacing filters in each indoor unit monthly during heavy use seasons and keeping the outdoor unit clear of debris.
Professional maintenance should be performed annually to clean coils, check refrigerant levels, inspect electrical connections, and ensure optimal performance. This preventive care is especially important in Atherton’s climate where systems may run year-round for both heating and cooling.
We offer maintenance plans that include priority scheduling, discounted repair rates, and comprehensive system inspections. Regular professional maintenance typically pays for itself through improved energy efficiency and prevented breakdowns, especially important when you’re depending on your system for year-round comfort.
Ductless mini-split systems are typically 20-30% more energy efficient than traditional central air conditioning. The efficiency advantage comes from eliminating ductwork energy losses and providing zoned comfort control so you’re only conditioning spaces you’re actually using.
Traditional ducted systems lose 20-30% of their energy through leaky, poorly insulated ductwork. Ductless systems deliver conditioned air directly to each room with minimal energy loss. The inverter technology in modern mini-splits also adjusts capacity to match demand rather than cycling on and off like traditional systems.
For Atherton homeowners with high energy costs, this efficiency translates to significant savings. Many clients see their cooling costs drop by 25% or more after switching to ductless, especially in larger homes where zoned control eliminates the waste of conditioning unused spaces.
