What size mini split do I need?
Sizing is based on square footage, ceiling height, insulation, and climate — as a rough starting point, a 12,000 BTU unit typically covers 500–600 sq ft, while an 18,000–24,000 BTU unit can handle 1,000+ sq ft. A proper load calculation is the most reliable way to confirm the right size.
What's the difference between a mini split and a heat pump?
A ductless mini split is a type of heat pump — it moves heat rather than generating it, providing both heating and cooling from the same unit. "Heat pump" more broadly can also refer to central, ducted systems.
What does SEER2 mean, and why does it matter?
SEER2 is the updated efficiency rating standard (replacing SEER) that better reflects real-world ductwork and airflow conditions. A higher SEER2 rating means better energy efficiency and typically lower operating costs.
Do mini splits need professional installation?
Yes — mini split installation involves refrigerant line work and electrical connections that require licensed HVAC installation. Improperly installed systems can lose efficiency or void the manufacturer's warranty.
How much does it cost to run a mini split?
Running cost depends on unit size, local electricity rates, climate, and how often it's used. High-SEER2 inverter-driven systems generally cost less to run than single-speed units of the same capacity, since they modulate output instead of cycling on and off.
How often does a mini split need maintenance?
Indoor filters should be cleaned every few weeks to a couple of months depending on use, with a full professional tune-up recommended annually. Regular cleaning keeps airflow and efficiency from degrading over time.
