Klimaire / KMIP-KIWP DIY Series
Klimaire DIY 36k R-454B 208/230V 4-Zone Mini-Split
The Klimaire KMIP-KIWP DIY Series 4-Zone 36k drives four heads from one 208/230V outdoor unit at a certified nominal SEER2 22.5, EER2 11.1, HSPF2 10 on current R-454B refrigerant. From the DIY-oriented line, heating starts at 36,000 BTU at 47F and follows a normal falloff to 27,400 BTU at 17F and 26,000 BTU at 5F.
It is a value-focused pick with high SEER2 for its class; professional installation is still recommended. It is not ENERGY STAR certified and sits below the top premium brands on brand and dealer support.
Dealer-quoted.

Compatible indoor units
This is an outdoor unit. You choose its indoor heads separately - up to the maximum this condenser supports - and you can mix room sizes and styles across the zones. The models below are the heads this unit is documented to pair with.
Wall-mounted air handlers
9k, 12k, 18k
Model numbers
- 9k: KIWP09H2-41T
- 12k: KIWP12H2-41T
- 18k: KIWP18H2-41T
Sizing note: do not just add up the rooms. Multi-zone condensers have a maximum total connected capacity, and connecting more head capacity than the unit is rated for is a common installer mistake that hurts efficiency and comfort. Match total head capacity to the condenser's rating.

Frequently asked questions
- Can I install the Klimaire KMIP-KIWP DIY Series 4-Zone 36,000 BTU R-454B 208/230V (KMIP436-H223-4) myself, or do I need a pro?
- Klimaire KMIP-KIWP DIY Series 4-Zone 36,000 BTU R-454B 208/230V (KMIP436-H223-4) is sold as a DIY-installable system. The electrical circuit is the part that is not DIY: plan on a licensed electrician for the dedicated circuit, and check whether your local permit office requires a permit for the install.
- Will the Klimaire KMIP-KIWP DIY Series 4-Zone 36,000 BTU R-454B 208/230V (KMIP436-H223-4) keep heating in a cold winter?
- The AHRI/ENERGY STAR certification lists 26,000 BTU/h of heating capacity at 5F. Rated heating operation extends down to -13 F. Certified heating efficiency is 10 HSPF2. Match those numbers against your climate's design temperature - in cold regions, output at 5F matters far more than the nameplate capacity measured at 47F.
- What electrical circuit does the Klimaire KMIP-KIWP DIY Series 4-Zone 36,000 BTU R-454B 208/230V (KMIP436-H223-4) need?
- Published electrical requirements: 230 V voltage, 22 A minimum circuit ampacity, and 35 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 from the outdoor unit to one indoor head is 98 ft. The combined piping limit across all heads is 263 ft. The outdoor unit's factory charge covers up to 98 ft of line; longer runs need added refrigerant. Measure the planned routing before ordering.
- What warranty does the Klimaire KMIP-KIWP DIY Series 4-Zone 36,000 BTU R-454B 208/230V (KMIP436-H223-4) carry?
- The manufacturer publishes these warranty tiers: Registered: 5 yr parts / 7 yr compressor (registration/installation terms). Score uses Registered.. Registration requirements and proof of qualified installation commonly affect coverage, so read the warranty terms before install day.
