Your home stays comfortable year-round without the energy waste of traditional systems. No more heating or cooling rooms you’re not using—ductless systems let you control exactly where your money goes.
You’ll notice the difference immediately: consistent temperatures in every room, whisper-quiet operation, and energy bills that actually make sense. Most Hillsborough homeowners are surprised by how much their monthly costs drop after switching to a properly sized, energy-efficient ductless system.
The best part? You’re done worrying about uneven temperatures, noisy operation, or sky-high utility bills. Professional installation means everything works correctly from day one, with the reliability you need when Hillsborough’s temperatures climb.
We’ve been serving Hillsborough families since 1985. What started with Ramiro’s father continues today with the same commitment to quality work and honest service that built our reputation in San Mateo County.
We’re the local company that understands Hillsborough’s unique climate needs. Our certified technicians know exactly how ductless systems perform in our Mediterranean climate—mild winters, comfortable summers, and everything in between.
We offer 15% discounts for seniors and military members because we believe everyone deserves comfortable, efficient cooling. When you work with us, you’re working with neighbors who’ve been part of this community for nearly 40 years.
First, we’ll assess your home’s specific cooling needs using professional load calculations. No guesswork—we determine the exact capacity needed for optimal efficiency and comfort in your Hillsborough home.
Next, we install the outdoor unit and connect it to indoor air handlers through small refrigerant lines. Each indoor unit controls its own zone, so you get customized comfort in different areas without the expense and energy loss of traditional ductwork.
We handle all permits, electrical connections, and system testing to ensure everything operates at peak performance. After installation, we walk you through your new system’s operation and set up a maintenance schedule to keep it running efficiently for years to come.

Every installation includes proper system sizing, professional ductwork assessment where needed, electrical connections, and comprehensive testing. We work with leading manufacturers to ensure you get reliable equipment built to perform efficiently in Hillsborough’s specific climate conditions.
Hillsborough homes benefit from ductless systems designed for our area’s mild temperatures and occasional heat waves. These systems work efficiently during our comfortable winters while providing excellent cooling when temperatures climb into the 90s and above.
You also get warranty protection on both our installation work and the equipment itself—typically 5-10 years depending on components. We handle warranty registration, ongoing support, and can set up maintenance schedules to protect your investment and keep energy costs predictable.
Ductless AC installation in Hillsborough typically ranges from $3,000 to $8,000 for most residential installations, depending on the system size, number of zones, and complexity of installation. Single-zone systems generally cost less, while multi-zone systems that cool multiple rooms cost more due to additional indoor units and installation work.
Factors affecting your total cost include your home’s size, existing electrical setup, the efficiency level you choose, and any additional features like smart controls or premium indoor units. Higher-efficiency systems cost more upfront but often qualify for significant rebates and tax credits that can reduce your net cost by thousands of dollars.
We provide detailed, upfront pricing before any work begins, so you know exactly what to expect. Most installations are completed in one day, and we handle all permits and inspections to ensure your system meets local codes and manufacturer specifications.
Yes, ductless systems are significantly more energy efficient than traditional central air conditioning. ENERGY STAR certified ductless mini-split systems use up to 60% less energy for heating and 30% less energy for cooling compared to conventional room air conditioners or older central systems.
The efficiency comes from eliminating energy loss through ductwork, which can account for 20-30% of cooling costs in traditional systems. Ductless systems also use inverter technology that adjusts compressor speed to match your exact cooling needs, rather than cycling on and off like traditional systems.
In Hillsborough’s mild climate, this efficiency translates to substantial savings on your utility bills. Many homeowners see their cooling costs drop significantly after switching to ductless, especially when replacing older, less efficient systems. The precise zone control also means you’re not wasting energy cooling rooms you’re not using.
Absolutely. Modern ductless heat pump systems provide both heating and cooling from the same unit, making them perfect for Hillsborough’s mild Mediterranean climate. These systems work efficiently in temperatures well below what we typically experience during our winters.
Heat pump technology extracts heat from outside air even in cold weather, making it much more efficient than traditional electric heating. In Hillsborough’s climate, where winter temperatures rarely drop below freezing, ductless heat pumps can handle your heating needs efficiently and cost-effectively.
Many homeowners find ductless heating more comfortable than traditional forced-air systems because there’s no noisy ductwork and no hot or cold spots. Each zone maintains its own temperature, so you can keep bedrooms cooler while keeping living areas warmer, all while using less energy than traditional heating systems.
Most ductless AC installations in Hillsborough are completed in one day, typically taking 4-8 hours depending on the number of zones and complexity of the installation. Single-zone systems usually take less time, while multi-zone systems with multiple indoor units require additional work for each zone.
The timeline can vary based on factors like the accessibility of installation locations, electrical requirements, and any unexpected issues we discover during installation. We’ll provide you with a realistic timeline during your initial consultation based on your specific situation.
We arrive fully prepared with all necessary equipment and parts to complete your installation efficiently. Our technicians are experienced with Hillsborough’s building codes and typical home construction, which helps us work quickly while ensuring everything is installed correctly and safely.
Yes, permits are typically required for ductless AC installation in Hillsborough, especially for systems that involve electrical work or multiple zones. The good news is we handle all permit applications and inspections as part of our service, so you don’t need to worry about the paperwork.
Permits ensure your installation meets local building codes and safety standards, which protects both your investment and your family’s safety. The permit process also ensures proper electrical connections and refrigerant handling, which are critical for system performance and longevity.
We’re familiar with Hillsborough’s permitting requirements and have established relationships with local inspectors, which helps streamline the process. All permit costs are included in your installation quote, and we coordinate all inspections to ensure your system passes on the first try.
Ductless systems require minimal maintenance in Hillsborough’s mild climate, but regular care is essential for optimal performance and longevity. Basic maintenance includes changing or cleaning filters every 1-3 months, which you can do yourself, and keeping outdoor units clear of debris and vegetation.
Professional maintenance should be performed annually and includes checking refrigerant levels, cleaning coils, inspecting electrical connections, and testing system controls. Hillsborough’s relatively mild climate means less wear on your system compared to extreme weather areas, but regular maintenance prevents small issues from becoming expensive repairs.
We recommend scheduling maintenance in spring before peak cooling season begins. Our maintenance service includes thorough system inspection, cleaning, and tune-up to ensure peak efficiency. Regular maintenance also maintains your warranty coverage and helps catch potential issues before they cause system failures or higher energy bills.
