3.5 MHI Air conditioner

The product does all we ask of it – giving us lovely cool air in summer and warm air in winter. It is a hassle free product we are happy with.

Works well hot or cold

The unit does its job very well in both hot and cold conditions. It is also very quiet and the controls are reasonably easy to operate. I will have no hesitation in acquiring another similar unit to cover the rest of our property.

Fills very large room

Quick to heat or cool very large dining/kitchen area with minimal noise. Maintenance is easy and the head unit is relatively unobtrusive. We feel the cost in terms of running the unit is very good value.
