A homeowner in the Southern California area contacted BOMING Air Conditioning & Heating to add cooling and heating to a newly converted garage ADU. The solution chosen was a complete installation of 2-ton TOSOT mini-split system for a Garage ADU.
Project Overview
The garage had been finished into living space but lacked any HVAC. The owner needed a reliable, independent climate-control system that would not rely on the main house equipment. After evaluating the space and insulation, the team recommended the 2-ton TOSOT unit sized specifically for the ADU load.
Why a 2-Ton TOSOT Mini-Split System
TOSOT mini-splits deliver inverter-driven efficiency and true zoned control. Because the ADU operates on its own schedule, a ductless system avoids the energy loss of long duct runs from the main house. The 2-ton capacity matches the square footage and insulation levels without oversizing, supporting steady temperatures and lower operating costs.
Installation Process
Technicians mounted the indoor wall unit on an interior partition and placed the outdoor condenser on a code-approved pad with proper clearances. Refrigerant lines were run through the wall and protected with line-set covers. Electrical work included a dedicated circuit and disconnect. The system was pressure-tested, evacuated, and commissioned with the manufacturer’s startup checklist. Total work was completed in one day with minimal disruption to the property.
Results and Homeowner Benefits
The ADU now maintains consistent comfort year-round. The inverter compressor adjusts output to match demand, reducing short cycling and noise. The owner gains independent temperature control, improved energy efficiency compared with portable units, and a clean finished appearance. Routine maintenance is simple: filter cleaning a few times per year keeps performance optimal.
