Instead of vinyl tubing we use hard pipe PVC for the condensation, seal all joints, straight line sets, secured power lines, sun-rated communication wire, flexible liquid tight, low ambient devices, disconnects and properly sized breaker for any inspection.
The Heating Ninja staff are trained for all aspects to perform brazing of the copper, pressure tested making it 100% sealed so that it may never leak, vacuumed and properly balanced with a digital temperature reader.
There is no AC permit required, but when we add a breaker to the house panel an electrical permit is involved.
Outdoor units preferred on the ground, on a supplied pad to reduce noise vibration but brackets are common when needed.
Winter covers are optional and extra as these units are weathered for year round use
Efficiency is rated as a SEER rating and comes as a single stage (13-17 seer), 2 stage, variable speed. 2 stage and variable speed units need a communicating furnace to operate them to their full capacity.
In most cases single stage condensers are used. The higher the seer rating the more efficient it is for power consumption. climates and all year use has to be considered to really make up for the expense and cost savings.
