The M-Series GS 36k is a discontinued (Production Stopped) R-410A single-zone at 3 tons - the largest of the old standard line: SEER2 18.4, EER2 8.8, HSPF2 8.5, with 35,200 BTU of heat at 47F. It conditioned big open spaces from one head; the current equivalent is the R-454B GX 36k, though a zoned system usually suits a load this large better.

Mitsubishi Electric equipment is sold through its dealer network; installed price depends on the local contractor.

Strengths

  • 35,200 BTU rated heat at 47F - maximum single-zone capacity in the old standard line.

Weaknesses

  • Production Stopped and R-410A - phase-out refrigerant.
  • SEER2 18.4 / EER2 8.8 - conventional efficiency; not ENERGY STAR certified.
  • The current GX 36k replaces it; at 3 tons, also consider a zoned multi-head design.

Frequently asked questions

Can I install the Mitsubishi Electric M-Series GS 36,000 BTU R-410A 208/230V (MSZ-GS36NA2 / MUZ-GS36NA2) myself, or do I need a pro?
Mitsubishi Electric M-Series GS 36,000 BTU R-410A 208/230V (MSZ-GS36NA2 / MUZ-GS36NA2) is built for professional installation: the line set must be flared, evacuated, and charged, which requires EPA-certified refrigerant handling. Installing it outside the manufacturer's requirements can void the warranty, so budget for a qualified HVAC installer.
Will the Mitsubishi Electric M-Series GS 36,000 BTU R-410A 208/230V (MSZ-GS36NA2 / MUZ-GS36NA2) keep heating in a cold winter?
Rated heating operation extends down to -4 F. Certified heating efficiency is 8.5 HSPF2. Match that published heating floor against your climate's design temperature - below the low-ambient rating, output can fall off or the system can pause to protect itself.
What electrical circuit does the Mitsubishi Electric M-Series GS 36,000 BTU R-410A 208/230V (MSZ-GS36NA2 / MUZ-GS36NA2) need?
Published electrical requirements: 208/230V voltage, 22 A minimum circuit ampacity, and 25 A maximum breaker or fuse sizing. Confirm the final circuit against the unit nameplate and local code with a licensed electrician.
How far can the outdoor unit be from the indoor head?
The published maximum line-set length is 100 ft. Measure the planned routing before ordering.
What warranty does the Mitsubishi Electric M-Series GS 36,000 BTU R-410A 208/230V (MSZ-GS36NA2 / MUZ-GS36NA2) carry?
The manufacturer publishes these warranty tiers: Base: 5 yr parts / 7 yr compressor (licensed HVAC contractor installation); Registered: 10 yr parts / 10 yr compressor (owner-occupied residence registered within 90 days of installation); Program: 12 yr parts / 12 yr compressor (owner-occupied residence installed and registered by a Diamond Contractor within 90 days). Score uses Registered. Additional published terms are shown for reference and not counted in the score.. Registration requirements and proof of qualified installation commonly affect coverage, so read the warranty terms before install day.
