Common questions
How big a mini-split do I need?
Based on the room load, not only size. Open floor plans and poor insulation need larger units.
Do mini-splits heat in winter?
Yes. Modern cold-climate models heat well down to about 5 degrees F or lower. They are often used as the main heat in a room or house.
Are they noisy?
Indoor units are quiet, about as loud as a whisper to a quiet conversation. The outdoor unit makes some fan noise, so placement matters.
