Start with the local property, not a generic BTU chart
George combines a busy regional centre with Garden Route lifestyle estates, retirement properties and family homes set against the Outeniqua Mountains. That mix makes reversible heating valuable: an inverter split unit can cool in summer and take the edge off a cold morning without a separate system.
Open-plan living spaces are common in newer estates, while established homes may have compartmentalised rooms that work better with separate zones rather than one oversized unit.
