How do I choose the right size mini split system for my room?

Mini split capacity is measured in BTUs (British Thermal Units) based on your space's square footage. As a general guide: • 500–700 sq. ft.: 12,000 BTU (1 Ton) • 700–1,000 sq. ft.: 18,000 BTU (1.5 Ton) • 1,000–1,500 sq. ft.: 24,000 BTU (2 Ton) Factors like ceiling height, sun exposure, and insulation also impact your heat load. Use our online BTU Calculator or contact our expert sales team at (737) 738-6329 for a free sizing assessment.

What is the difference between single-zone and multi-zone mini splits?

A single-zone mini split pairs one outdoor condenser with one indoor air handler, ideal for cooling or heating a single room, garage, or addition. A multi-zone system connects one high-capacity outdoor unit to up to 5+ indoor air handlers (wall mounts, ceiling cassettes, or concealed ducts), allowing you to set independent temperatures across multiple rooms.

Does South Mini Splits offer free shipping?

Yes! We offer free standard shipping on qualifying orders over $300 on select authorized brands across the contiguous U.S. Freight orders are securely strapped to pallets and delivered via trusted carrier partners with tracking updates provided from dispatch to driveway.

Can I install a mini split system myself, or do I need a licensed HVAC technician?

While handy DIYers can complete the physical mounting, line set routing, and component placement, final system start-up, pressure testing, and refrigerant connection must be performed by a licensed EPA-certified HVAC technician to validate manufacturer warranties and ensure leak-free operation.

What indoor unit styles are available besides wall-mounted units?

South Mini Splits carries a wide range of aesthetic and functional indoor air handler styles: • Wall-Mount Systems: Traditional, high-efficiency wall units. • 4-Way & 1-Way Ceiling Cassettes: Low-profile units recessed directly into the ceiling. • Concealed Slim Duct Systems: Hidden in attics or drop ceilings for invisible ductless comfort. • Floor Console Units: Low-profile units ideal for replacing old radiators or knee-wall spaces.

Are South Mini Splits products covered by manufacturer warranties?

Yes. South Mini Splits is an Authorized Dealer for top HVAC brands, including Cooper & Hunter, Bravo, OLMO, Daikin, Goodman, MRCOOL, and ACiQ. Buying through an authorized dealer ensures you receive genuine factory-backed equipment, full manufacturer warranty coverage, and dedicated technical support.

Does South Mini Splits offer HVAC financing?

Yes, we offer flexible financing options—including interest-free installment plans through partners like Afterpay—to help qualified buyers spread out equipment costs over manageable monthly payments during checkout.

What is the difference between R-410A and R-454B refrigerant systems?

R-410A has been the long-standing industry standard refrigerant, while R-454B is a next-generation, low-GWP (Global Warming Potential) refrigerant compliant with newer environmental regulations. South Mini Splits stocks both R-410A inventory for multi-room replacement projects and R-454B systems for modern, eco-friendly builds.
