Performed Precision Air Conditioning Tune Up on Nordyne System. Replaced High Efficiency 413 Air Filter and 14x14x1 Air Filter. Cleaned Condensation Pump and Drain Line. Filled and tested operation of Pump. While testing Electrical Components, found Blower Motor Capacitor was testing below its rating. Replaced the 15 Mfd Capacitor and tested operation of system. Measured Refrigerant Charge on system which was very low. Superheat was at 63 Degrees with a 0 Degree Subcooling. System was only producing a 5 Degree Supply Versus Return Air Temperature Split. Refrigerant and Leak Dye had been added to the system in June 2017. Used UV Light and Glasses to search Indoor and Outdoor Coils for Dye. Found traces of Dye on the Indoor Coil at the back right corner of the Coil. Need to call Nordyne for pricing on replacement of the Indoor Coil with TXV. Was not able to find any other leak sources at this time. There may be additional leaks in the system. To get the system running properly, added

Found wet switch tripped. Found that possibly tripped due to humidity. Found drain line open poured water down drain and went down fine . Found no water in drain pan. Only they cloth pad connected to the wet switch was damp so dried out and placed a paper towel under wet switch. Told homeowner that if it would ever shut down on a real humid day again, to check the drain pan first so see if any water has accumulated. Ac is back and working fine again. Homeowner is on the maintenance plan.

Checked no cooling complaint, found low voltage fuse blown, Wayne said he replaced it Friday and the air handler started but no outdoor operation. Checked for shorts and grounds, found nothing. Replaced fuse, blower started, checked outdoor no 24 volts to r, y. Checked outdoor cable it must be cut somewhere between the air handler and the outdoor unit. Will need to use a wireless control to run the heat pump Need a wireless control to operate the heat pump To be billed from the office did not emailed

Found head pressure climbing system was locked out on high pressure lock out in cooling mode. Sent to replace previous diagnosed indoor txv, pumped down as much as possible, recovered line set and indoor coil refrigerant. Removed txv, installed new txv. Pressure tested at 150 psi. Replaced liquid line filter drier. Evacuated system to 400 microns, held for 5 minutes. Started heat pump, balanced refrigerant charge by sub cooling. Checked operation and temperature drop across coil. To be billed from office. Did not email.

Found outdoor Rudd heat pump on high pressure lockout. Reset defrost board and hooked up gauges. Found head pressure going up to 322 psi and climbing at 69 degrees outdoor temp. Also had a subcooling of 24. Found that indoor txv was not working correctly. Will pump charge back into compressor as much as possible and replace filter dryer. Also add refrigerant if needed .

Installed new mini split for outdoor back sun room ran refrigerant lines through soffit down wall there is a union outside in the back to connect linesets , because of length. We installed a condensate pump in the soffit as well drains out back. Ran new power wire and installed breaker, whip, disconnect, outdoor unit was set and leveled on pad in front right of home all penetrations were caulked. Communication wire was run with linesets. Unit was triple evacuated and vacuumed reached 385 microns for 10 minutes. Tested the delta t on the unit and return air was - 67.6 and our supply air was -48.5 bringing our delta t to- 19.1

Found 3 amp fuse popped in indoor air handler. Went through process of elimination by disconnecting low voltage wires from outdoor unit, now fuse did not pop. Hooked up r&c to outdoor defrost board now it popped again. Went over all low voltage at outdoor unit and foun no nicks to ground. Removed all low voltage wiring to outdoor defrost board. And powered with r&c popped again. Issue is in the defrost board will call and order new board Wayne, to install board from another unit temporarily.

Service call that the AC for the Second Floor System was not Cooling. Found Thermostat set to 70 Degrees and the Indoor Temperature was at 76 Degrees. The Indoor Coil was frozen and needed to be defrosted before further troubleshooting. Defrosted Coil and put system into operation. Found Refrigerant Temperatures/Pressures to be well below normal. Replaced the High Efficiency 413 Air Filter which was very dirty. Also found Fan Speed was only running at 700 CFM for a 3-Ton AC system. The Dipswitches for Cooling Air Flow were not set properly. Set Dipswitches for Cooling per Furnace at 400 CFM per Ton. Also found unit to wired for Low Stage Cooling. Rewired to the correct Terminal. Retested Refrigerant Levels which now were greatly improved, however the Superheat was at 25 Degrees with a 2 Degree Subcooling. Added 3lbs of 410-A Refrigerant to the System, Charging by Subcooling. Upon completion the Subcooling had increased to 8 Degrees. Supply versus Return temperature increased from 14 to

We added a coil and outdoor unit customer requested it be on pump ups to avoid weed whacking issues. Ran new line set and thermostat wire to both outdoor and new thermostat as well. Ran seal tight around power wire to outdoor and up to disconnect. New disconnect whip and pad installed. New vinyl ran. We put an outlet in for the condensate pump to plug into installed ez trap.. unit needs to still be wired up for operation fan center need installed. All wires from thermostat and outdoor and saftey switch ran to right side of unit for wiring.

Performed Precision AC Tune Up on Carrier System. Checked 16x25x1 Air Filter. Filter was recently changed and still in good condition. Cleaned Condensation Drain Line and Pump. The unit sits in an Auxiliary Drain Pan but does not have any Water Safety Devices Installed. Would recommend installing an EZ Trap, Wet Switch, and Wiring Condensation Pump into the System. If the Pump or the EZ Trap become clogged they will shut power off to the system. If the Wet Switch detects Water in the Auxiliary Pan it will shut power off to the system. Please see attached estimates. Measured Refrigerant Charge on system which is to standards at this time. Found the Capacitor on the Outdoor Unit Testing to rating, but it is rusted due to the Furnace Exhaust Vent being located near the Unit. The Venting may need to be redirected away from the Unit to prevent further damage. The Vent Pipe currently is located about 2’ below a window.
