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.

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.

Performed Precision AC Tune Up on Carrier/Bryant System. Replaced the 20x20x1 Air Filter. Recommend using Merv-8 Filters and checking every 30-45 Days. Cleaned EZ Trap on System. Inspected Electrical Components on Air Handler and Outdoor Unit. Measured Refrigerant Charge on system. Used Charging Jacket to verify Refrigerant Levels due to lower Outdoor Temperature and rain.Spoke with Homeowner about noise issue coming from the vents. The sound of the AirFlow is “pulsating” when the system is operating. Opened several of the Vents on the Second Floor which did not change the sound. Checked X13 Blower Motor Fan Speed which is set to “Medium”. The Air Handler and Outdoor Unit are both rated at 4-Tons. Due to size of system, do not recommend lowering Blower Speed to the lower setting. Nine 6” Flex Runs are visible when in the Attic. Most of these Flex runs are not installed correctly and have a lot of excess ductwork. Due to the noise issue and only being able to locate 9 Flex

Performed Precision Air Conditioning Tune Up on System. Replaced the High Efficiency 401 Filter. The Condensation Pump was an old style Pump. These pumps have had issues with the motors failing, and their is no safety device to shut the system down. Recommended and installed a new 115V Condensation Pump with an internal safety. If the Pump fails to discharge the water and the tank fills, it will trip the internal switch and shut the 24V power off to the system. Filled Pump and tested operation. Tested safety switch on Pump to ensure it would shut the system down. Inspected Electrical Components on the Indoor and Outdoor Units. Measured Refrigerant Charge on system.While System is operating, and Refrigerant levels are to standards at this time, the system is about 18 Years old. Due to age of System, it is recommended to begin planning/saving for replacement of the Gas Furnace/AC.Showed Homeowner how to remove and reinstall filter on Dehumidifier in Crawl Space.
