Back of the building system servicing the shop and the loft is very low on refrigerant running at 34 PSI suction in emergency override cooling mode and holding 125 psi when turned off System required 66 oz of new r410a to achieve an acceptable running pressure with all four systems and emergency override cooling mode. Current running refrigerant pressures are 130 and 362 Due to the complexity of the system ultraviolet dye is recommended with a recharge to positively identify the location of the refrigerant leak Recommend follow up ultraviolet dye leak search on 4 indoor head units in 2-4 weeks
2012 water furnace Envision nsv042 system is running in very good condition. Homeowners only concern is corrosion on multiple fittings associated with the hot water generator copper lines. Water furnace branded Emerson touch screen thermostat is in good condition with no corrosion or battery lights Visible corrosion buildup on the water lines does indicate a leak at some point in time and possibly a continuous long-term leak. recommend plumbing company replace the damaged fittings and shut off valves. Water flush and power flush the drain system, run test system refrigerant pressures at 126 PSI suction with 14 superheat at 57° Ground loop water pressure is stable at 18psi and in range with a minimum 15 requirement. Air filters are on schedule with homeowner and appear to be in like new condition Humidifier operation is questionable and bypass air flow damper was closed today. Controls were not adjusted All equipment is clean safe and ready for the remainder of Summer

2005 water furnace premier, pressurized closed loop system Upon arrival the system was working in good condition in cooling mode with a regular work order for general seasonal maintenance Initial inspections and minor maintenance cleaning in the electrical compartment discovered loose high voltage wiring arcing multiple times during the inspection. While searching for the cause of the electrical noise the integrity of the water furnace premier control board was compromised and the system shut down and would not reinitialize the compressor operation Install replacement water furnace premier control board from service stock Complete all the general duties of the maintenance including drain flush, minor maintenance air dusting and cleaning, filter rotation provided by homeowners, ground loop pressure testing, cooling mode operation testing Considering the age the equipment is running in very good condition All wiring in the electrical compartment has been inspected and secured.

Two multi-head systems each containing four indoor head units and one outdoor unit. Owners are very concerned with the improper installation of the equipment that may result in a lawsuit against the installing contractor or general contractor. Today's inspection test run and minimal disassembly for test running has has concluded with several results. 1- The drain line manifold in the shop mechanical room is higher than the wall mounted units and will not drain upward to go over a wall.. Even with the assistance of Blue diamond Maxi pump the pressure of a 2-in manifold 4 ft tall holding water cannot be overcome by the pump pressure and is creating water overflowing and a leakage issues at every head unit in the building. The drain line terminations from each pump need a non-pressurized gravity reservoir or drain to spill into to prevent any back pressure of water and/or sludge buildup. Owners have eight new blue diamond maxi pumps on site and would like every pump replaced because
