36,000 BTU Mini Split Air Conditioners

36,000 BTU systems — the 3-ton class — are one of the most popular capacities we sell, with enough output to condition roughly 1,200 to 1,600 square feet depending on ceiling height, insulation, and climate. This collection includes multi-zone mini split bundles that split 36K across two, three, or four rooms (combinations like 18K+18K, 12K+24K, or 9K+9K+18K), plus central ducted heat pump systems such as the MRCOOL VersaPro for whole-home applications.

If you want to install a system yourself, look at the MRCOOL DIY 5th Gen bundles — they ship with pre-charged quick-connect line sets, so no HVAC technician or vacuum pump is required. Standard systems typically cost less up front but call for professional installation. Every system here is a true heat pump, so the same equipment delivers air conditioning in summer and efficient heating in winter.
