Mitsubishi M-Series R-22 Discontinued Models & Replacements
This page lists 115 discontinued Mitsubishi Electric M-Series R-22 models with the current R-454B replacement we stock, plus installation, operation, service and parts manuals for each old model. Mitsubishi usually renames a series with a one-letter change when it updates it (for example MSZ-GS became MSZ-GX), so the replacement keeps the same capacity and unit style.
Before you order: replacements are matched by unit type, capacity, heat pump vs. cooling-only and hyper-heat capability. Always verify line-set size and condition, electrical supply, controls and indoor/outdoor compatibility before ordering. Discontinued indoor and outdoor units cannot be mixed with current R-454B equipment; replace both sides of the system. R-22 systems require a new or properly flushed line set. Questions? Contact our team with your old model number.
