Question 1

How many rooms can a mini-split system cover?

Accepted Answer

A single outdoor unit can typically support 2–5 indoor units (zones), each independently controlled. This means you can heat and cool multiple rooms from one system, each set to a different temperature.

Question 2

How is a mini-split installed?

Accepted Answer

We mount the indoor unit on your wall, connect it to the outdoor unit through a small 3-inch hole in the wall for refrigerant lines and wiring. There's no ductwork involved. Most single-zone installations are done in half a day.

Question 3

Are mini-splits noisy?

Accepted Answer

No — the indoor units are very quiet, typically around 20–30 decibels (quieter than a whisper). The compressor noise is all outside. This is one of the main advantages over window units.

Question 4

Can a mini-split heat in winter?

Accepted Answer

Yes. Most modern mini-splits are heat pumps that provide both heating and cooling. Cold-climate models work efficiently well below -20°C. They're one of the most efficient ways to heat a room.
