🤔 What is BTU and TON?
BTU (British Thermal Unit) is a measurement used to gauge how much heat an air conditioning or heating system can move in an hour. A higher BTU rating indicates a more powerful system capable of handling larger spaces. Essentially, knowing the BTU helps you choose the right-sized mini-split for your home, ensuring maximum comfort and energy efficiency.
TONN, often used in HVAC systems, refers to the cooling capacity equivalent to BTUs per hour, helping you understand the system's power in more familiar terms.

A 55 k BTU outdoor unit can serve up to 3 to 5 indoor zones, covering approximately 2,800–4,000 sq ft, depending on insulation and layout. Choose configurations like (24k+18k+12k) for open-plan homes or (12k×4 + 6k) for more rooms. Use our “Size‑My‑Room” tool at MiniSplits4Less.com to determine your ideal indoor head mix.
Can I install a 55,000 BTU system myself?
