MRCOOL is the leading name in DIY HVAC: its DIY Series ships with pre-charged, quick-connect line sets, so a handy homeowner can install a single-zone system in an afternoon with no vacuum pump, no refrigerant license, and no HVAC contractor required. Prefer a pro install? Universal and Olympus series systems deliver the same high-SEER2 inverter efficiency in a conventional-install package. Choose a single-zone unit for one room — a garage, sunroom, addition, or shop — or a multi-zone system that runs up to five air handlers off one outdoor condenser, mixing wall-mount, ceiling-cassette, and ducted heads to fit each space.
Sizing is simple: roughly 9,000 BTU covers about 350–400 square feet, 12,000 BTU about 500, 18,000 BTU about 750, and 24,000 BTU about 1,000 — with cold-climate models that keep heating well below freezing.
