⚡ Direct Answer for San Antonio Homeowners
Choosing between a Ductless Mini-Split and a Traditional Central AC depends on your home's architecture. Central AC is best for whole-home replacement where existing ductwork is intact and sealed. Ductless Mini-Splits are superior for room additions, converted garages, sunrooms, or historic Alamo Heights homes without attic space. Mini-splits offer ultra-high efficiency (up to 33 SEER2) because they bypass the 20% energy loss associated with leaky ductwork, and they qualify for major CPS Energy rebates.

1. How Ductless Mini-Splits Work vs Central AC
Traditional central systems use a massive outdoor condenser and a single indoor air handler to blast cold air through an entire network of sheet metal ducts. A ductless mini-split eliminates the ducts entirely. It links a compact outdoor condenser directly to individual indoor wall units (heads) using small refrigerant lines.

2. SEER2 Efficiency & The Ductwork Loss Factor
According to the US Department of Energy, up to 30% of energy is lost in ductwork due to leaks and thermal transfer in 130°F Texas attics. Because mini-splits deliver cold air directly into the room, their SEER2 ratings routinely hit 22.0 to 33.0, far outpacing the 16.0 SEER2 average of central systems.
3. Installation Costs & Rebates in San Antonio
A single-zone mini-split generally runs between $4,000 and $6,500 fully installed. High-efficiency multi-zone heat pump mini-splits qualify for both the $2,000 Federal Tax Credit and CPS Energy rebates.

Can one mini-split cool an entire house?
No, a single unit cools a single zone. For a whole house, you would need a multi-zone system with a massive outdoor compressor driving 4-5 indoor units.
Are mini-splits loud?
No! They are incredibly quiet. Indoor wall units operate as low as 19 decibels, which is quieter than a whisper.
Can I use the $500 Voucher for a mini-split?
Yes, the InfiniSolve $500 Replacement Voucher is completely valid for new mini-split installations by our certified partners.
Do mini-splits provide heat too?
Yes, most modern ductless systems are heat pumps, meaning they provide extreme cooling in summer and highly efficient heating in winter.
How long does installation take?
A single-zone mini-split can typically be installed by a professional crew in just 4 to 6 hours.
