Tested system for rear side of the home. Tested cool from thermostat. Found low-voltage wiring loose and not ran very well. Also mini install issues found including supply and return Plenum leaking air, two different size line sets, no flood, protection installed, no locking caps, missing a disconnect for the air handler, and the blower wheel is very dirty. The supply and return is not sealed along with not being insulated. Also, the drain line does not have a P-trap installed. The supply duct is falling off of the return because it is pulled too tight. Will need to return to complete all repairs.
