What this specific model is sized for, how it installs, how it performs, and what it costs to run.
Room & Space Coverage — 18,000 BTU
The 1.5 Ton MRCOOL® VersaPro® Central Ducted Air Handler delivers 18,000 BTU of cooling and heating capacity (1.5-ton class), sized for spaces up to 900 sq ft in standard 8-ft ceiling rooms with average insulation. At this capacity the unit handles medium primary rooms, master suites with attached bath, converted garages, and workshops. If your space includes a sunny west-facing wall or a finished bonus room above it, lean toward the upper end of the coverage range.
Power & Electrical Requirements
Power requirement: 115/208-230V 1-phase 60Hz (standard US residential 240V service). Minimum circuit ampacity is 5.54A with a maximum overcurrent protection of 15A. Wire the outdoor unit with 14 AWG copper on a dedicated 15A double-pole breaker (or single-pole at 120V), with a disconnect within sight of the condenser per NEC 440.14.
Install Difficulty — Professional Install
This is a professionally-installed condenser that requires a licensed HVAC technician with EPA 608 certification. The tech will pull a vacuum on the line set to 500 microns, pressure-test with nitrogen, release the factory charge, and commission per MrCool's startup procedure. Budget 1 full day for install on a single-zone system. The system supports line set lengths up to 98.4ft; longer runs are available as accessory kits. Plan the shortest practical route — every 10ft of line set adds roughly 2% capacity loss.
Sound Level & Comfort Features
Operating sound level ranges from 33 dB(A) on low to 44 dB(A) on high — the low end is whisper-quiet, below a normal conversation (60 dB) and comparable to a library reading room. The indoor blower offers 4 fan speeds plus auto mode, letting you trade airflow for quiet operation in bedrooms while running louder in living areas.
Warranty & Certifications
Manufacturer warranty: 10 Years on parts, 10 Years on the compressor. AHRI certified — required for most utility rebate and tax credit programs.
What's in the Box & Compatibility
Ships as a Split System Heat Pump Air Handler.
