Common questions about ductless mini-split systems in San Antonio

Mini-Split FAQ

A single-zone ductless mini-split system in San Antonio costs $3,000 to $5,000 installed. Multi-zone systems (2-4 indoor units connected to one outdoor unit) cost $5,000 to $15,000. Costs include the outdoor condenser, indoor air handler(s), refrigerant line set, electrical connections, and installation labor. C.S.W. Power Solutions provides a free estimate with all costs itemized.
Yes. Mini-split systems are excellent for San Antonio's climate. They provide both cooling and heating, are highly efficient (up to 30 SEER), and allow zone-by-zone temperature control. They are ideal for room additions, garage conversions, sunrooms, home offices, and older homes without ductwork. In San Antonio's mild winters, mini-splits provide efficient heating down to about 5°F.
A single-zone mini-split installation typically takes 4 to 6 hours. A multi-zone system (2-4 indoor units) takes 1 to 2 days. Installation includes mounting the indoor unit, placing the outdoor condenser, running refrigerant lines, making electrical connections, and testing the system. C.S.W. Power Solutions handles all electrical work in-house (TECL 31793) — no separate electrician needed.
No. Mini-split systems are ductless — they use a small refrigerant line (3-inch hole through the wall) to connect the indoor air handler to the outdoor condenser. This eliminates the energy loss associated with ductwork (20-30% in typical systems) and makes installation much simpler. Mini-splits are the best solution for spaces without existing ductwork.
A single outdoor condenser can support 2 to 5 indoor units (zones), each independently controlled. Each indoor unit cools one room or area. A single-zone system handles one room up to about 750 square feet. Multi-zone systems can cool an entire small home or multiple rooms in a larger home. C.S.W. Power Solutions performs a load calculation to determine the right system size for your space.
Yes. Mini-split systems are among the most energy-efficient HVAC options available. They achieve SEER ratings of 20 to 30+, compared to 14-18 for most central AC systems. Because they are ductless, they avoid the 20-30% energy loss from ductwork. They also use inverter-driven compressors that adjust speed to match demand rather than cycling on and off. Most homeowners see 30-50% energy savings compared to window units or older central systems.
