Set new unit in new 30x60 drain pan. Adapted to Supply and return ducts. Ran new lineset from outdoor unit to indoor unit. Made all high and low voltage connections to unit. Ran new condensate drain to existing gravity drain. Wired all safeties in series to break 24v R call to thermostat. Set new unit on new pad and snowlegs and leveled. Hung new disconnect box with internal surge protector and sealed to wall. Ran new slim duct. Piped in lineset. Brazed pressure tested evacuated and charged system. Made all high and low voltage connections to unit. Performed all test out procedures cleaned all work areas and reviewed installation with homeowner. Check pressures in warm weather.

Perform tuneup on Lennox AC, checked indoor unit blower and temperature split, clean drains and replaced filter. Went to after unit and checked all electrical and mechanical components, including compressor fan motor and capacitor. Check refrigerant levels, system has no issues at this time.

Performed precision a/c tune up on (2) Trane heat pumps. Small unit for lobby and dojo 7.5 ton unit. Checked all electrical conections and components. Checked temperature splits. Checked refrigerant pressures and temperatures at indoor and outdoor units. Replacement of all filters. Check coils and blowers. Lobby unit is running within manufacture specifications. Dojo area unit had previous added dye and refrigerant. Checked indoor coil and outdoor unit for any visual leaks. Did not find any signs of leak at the time. Will need more time to show. also during inspection found indoor coil partially blocking airflow. Will be very difficult to clean coil. We been using brush to clean I was able to see dust/dirt penetrated between coil plates. Cleaning coil in place is not guarantee coil will be totally clean. I would also recommend replacement or filters every three months.

Cleaned customers condenser coil, removed entire casing and fan shroud from outdoor unit and thoroughly cleaned outdoor coil. Re assembled entire outdoor and all panels and rewired fan after unit was cleaned. Tested unit after and found no issues with system.

Performed precision a/c tune up on trane heat pump system. Replaced 16x20x1 air filter. Checked all electrical connections and components. Found weak 40/5 capacitor. Replaced capacitor and tested. Checked temperature split. Checked refrigerant pressures and temperatures at indoor and outdoor units. System is working fine at time of service.

Did a QA on a new trane 2stage gas furnace . Check the cleanliness of all the wires and connections. Inspected the the gas line to check for leaks started the gas furnace and inspected the gas pressure for the first and second stages. Checked the flue piping and checked the drain lines. I did move the 3/8 tubing from the outside to the indoor sink tub. Checked the control board for proper set up and checked the thermostat for set up. Everything is in good working order

Checked refrigerant pressures and temperatures. System is operating appropriately at this time supplying an appropriate temperature drop. Had Jim drop off four bags of salt for water softener.Collected payment for salt, condensate treatment and filter.

Performed tune up on Bosch heat pump, customer stated fan make a pulsing sound on start up so I tested the fan thoroughly and found no electrical issues with motor. Fan does make a rattling sound that comes and goes every 10-20 seconds then subsides completely after about 2 minutes of run time. Spoke with Joe about issues and he said to take a video and add it to the call and order a new fan motor and wheel and replace both .other than that system has zero issues in either heating or cooling mode. Spoke with customer about a surge protector and he agreed to install one when we come back for fan motor replacement.
