EasyPro 5th Generation 12k BTU 115V Air Handler — Model Details
What this specific model is sized for, how it installs, how it performs, and what it costs to run.
Room & Space Coverage — 12,000 BTU
The EasyPro 5th Generation 12k BTU 115V Air Handler delivers 12,000 BTU of cooling and heating capacity (1-ton class), sized for spaces up to 550 sq ft in standard 8-ft ceiling rooms with average insulation. At this capacity the unit is ideal for bedrooms, home offices, sunrooms, and single-room additions up to the stated square footage. Rooms with one exterior wall and average shading sit comfortably in the middle of the coverage range.
Power & Electrical Requirements
Power requirement: 115V 1-phase 60Hz (standard US 120V household outlet). Minimum circuit ampacity is 3A 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 — DIY-Friendly
This EasyPro 5th Gen system ships with a pre-charged Quick Connect line set — no HVAC license, no vacuum pump, no refrigerant gauges. The pre-charged fittings use a hand-tightened mechanical seal that a homeowner completes in 15 minutes per connection. Typical install time from unboxing to first cool air is 4–8 hours for a single-head system.
Sound Level & Comfort Features
Operating sound level ranges from 17.5 dB(A) on low to 44.5 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 5 fan speeds plus auto mode, letting you trade airflow for quiet operation in bedrooms while running louder in living areas. Sleep mode automatically raises cooling setpoint 1–2°F over 7 hours to match the body's natural temperature drop and cut overnight energy use.
Warranty & Certifications
Manufacturer warranty: 1 Year on parts, 2 Years on the compressor. AHRI certified and UL/ETL listed for North American electrical safety — required for most utility rebate and tax credit programs.
What's in the Box & Compatibility
Ships as a Mini-Split Air Handler with remote control included.
