Air conditioning system guide
Compare wall systems, understand the technical details and explore specialist options. Mitsubishi Heavy Industries wall units are available through our Instant Quote; other formats and brands are handled personally by our team.

More ways to condition a space
Wall-mounted Mitsubishi systems are the only type currently priced in the Instant Quote. We still show specialist alternatives because a cassette, concealed ducted, floor-standing or ceiling-suspended system may be a much better fit—and we would rather help you specify it properly than lose the enquiry.
Can’t see what you want in the Instant Quote?
A cassette, ducted or floor-standing installation needs more design information than a standard wall unit, so it should not be forced through the same fixed-price journey. Send us the room details and we’ll discuss the right equipment and survey requirements.
Technical catalogue
The wider Mitsubishi Heavy Industries range below helps you understand what is possible; not every configuration is currently available through the Instant Quote. Search an exact model number or filter by brand and indoor-unit style. Technical figures have been rewritten for this DAC guide, without publishing supplier pricing.
Try a shorter model number or clear the selected filter.
Technical figures are rewritten manufacturer data, not room-sizing advice, a stock promise or a final equipment selection. “Instant Quote” means that family can begin the online pricing journey; it does not promise the exact row shown. Specialist systems and larger capacities require a tailored installed quote.
Technical figures, in plain English
The system’s rated cooling capacity. Bigger is not automatically better: correct sizing improves comfort, humidity control and efficiency.
A higher SEER means more seasonal cooling delivered for each unit of electricity under the standard test method.
A higher SCOP means more seasonal heat delivered per unit of electricity. Actual running cost still depends on weather, settings and the building.
The current systems listed here use R32 refrigerant and must be installed and commissioned by an appropriately qualified engineer.
Choose the right next step
For a Mitsubishi wall unit, use the Instant Quote for an installed price. For cassettes, ducted, floor-standing, ceiling-suspended or another brand, tell us what you need and we’ll prepare a tailored recommendation.
