Ductless air conditioning systems, also known as mini-splits, offer a flexible and efficient cooling solution for homes and spaces where traditional ducted systems aren't practical. These systems consist of an outdoor compressor unit connected to one or more indoor air handlers, with no ductwork required. Mini-splits are ideal for room additions, converted garages, older homes without existing ductwork, server rooms, and any space where you want independent temperature control. Each indoor unit has its own thermostat, allowing different temperatures in different rooms—perfect for family members with varying comfort preferences. Ductless systems are also incredibly efficient. Without ducts, there's no duct loss (which can account for 20-30% of cooling energy in ducted systems). Most mini-splits have SEER ratings of 20 or higher, making them among the most efficient cooling options available. Many models are ENERGY STAR certified and eligible for utility rebates. We install, repair, and maintain all major mini-split brands, including Mitsubishi, Fujitsu, Daikin, LG, and Samsung. Our technicians are factory-trained and certified to work on these specialized systems, ensuring proper installation and service.

Frequently Asked Questions
How many indoor units do I need?
Generally, you need one indoor unit per room or zone you want to control independently. A single outdoor unit can support multiple indoor units (multi-zone system), typically 2-8 depending on the model.
Are ductless systems really more efficient?
Yes! Ductless systems eliminate duct losses and use inverter technology that modulates capacity to match demand, rather than cycling on and off. Most mini-splits have SEER ratings of 20-30+, compared to 14-18 for typical central AC.
Can mini-splits heat as well as cool?
Yes! Most mini-splits are heat pumps that provide both heating and cooling. They're very effective in mild climates like the Bay Area and can be a primary heating source or supplement to an existing heating system.
