Installed Low Flow Center Reservoir on Units that serve right side of house. Had to drain loop, cut piping, Fuse in adapters, connect piping to flow center and reservoir, then flush loop and check for leaks. Found no leaks so we added fluid to reservoir and tested pumps. Removed any additional air from system and returned power to units. Ran pumps again and ran units in heat to test. Normal operation.

Upon my arrival I found the drain line was full of water and water was sitting in the evaporator coil drain pan as well. I surmised it had to be very clogged in the homemade u trap. I spoke with service manager and the customer about installing an EZ Trap condensate assembly with built in safety device. By installing this I could cut out the old trap and replace with EZ Trap. I cut old trap out and it was clogged like plaque in arteries. I installed EZ Trap and wired it in. I poured lots of water through the pan to make sure it drained from there with no leaks. I showed the customer how to use the brush. Unit operating normal.

Upon arrival I found both systems locked out on water flow. Checked water filter for loop and found it to be mostly black and clogged. Hooked up hose and bucket to port and flushed out filter. Debri from pipes came out as well. Purged each unit as well. Returned power to units and ran ac. Measured deltas and checked operation. Both units operating normal. Warranty to PM per Alex, called Darlene and asked her to put a permanent note in for us to clear filter every pm.

Upon my arrival I pressurized the ground loop to 65 psi. I then checked the electrical wiring and electrical systems, all are within specification. I checked the air filters for each unit and they are not ready to be replaced. By winter they should be replaced. Coils and blower wheels are clean. I cleaned the condensate pans and drain lines and ran hot water to flush the debris and to check for any leaks and for proper drainage. I operated each unit on second stage cooling mode and checked pressure drops and heat of rejection and cooling across the evaporator coils. Both units are operating normal. Unit #1 has an Intellistart Module already installed. I recommend adding one to unit #2.

Upon arrival I was told multiple repairs were made on system in the past few weeks and unit is still not cooling. During diagnostics I checked AHU and found no problems. Called for ac and put gauges on to find 150psi suction and 500psi discharge, almost 0degree Superheat and very high subcooling. Removed some refrigerant from system to bring pressures down to 123psi suction 230psi discharge, 12 degree Superheat, 9 degree subcool, 21 degree delta air temp. Unit operating normal at this time. System was overcharged and going off on high pressure.

I found unit not cooling with 12-14 degrees. I applied my refrigerant gauges and pressures were low. I isolated the txv sensing bulb to test and rule it out. I then performed electronic leak search and found leaking valve stems. I tightened all valve stems put caps with rubber inside of them and added 2lb 8oz of refrigerant to achieve 10-12 degrees subcooling, 20+ degree delta temperatures across the evaporator coil and normal refrigerant pressures. Unit operating normal.

I operated both units on heating and cooling mode. Unit #1 is a gas furnace with air conditioning. Unit #2 is a heat pump. I checked the electrical wiring and electrical systems, all were within specification except for the blower motors voltage absorption system for unit #1, which was replaced. I had normal temperature rise for gas heating, #1. Unit #2 had normal heating and I tested the auxiliary heat strips as well. I replaced the Aprilaire #213 filter in the attic for unit #2 and installed an Aprilaire upgrade kit #413 in unit #1. Both 7 it’s in cooling mode had 20+ degree delta temperatures across the evaporator coils. Coils, indoors and outdoors are clean alas well as the blower wheels. Refrigerant pressures were normal for both units. Unit #1 uses r22 refrigerant and unit #2 uses r410a refrigerant. At this time there are no apparent refrigerant issues. I ran water through the drains and both drained properly. There is a pan switch in the attic. Both units are operating normal.

Upon arrival I went to system and found loop pressure reading 2psi static. Shut off units and installed Automatic Water Valve. Installed water valve between buffer tank and loop, connecting hose to exiting side of flow center. Routed hoses behind water pipes so it isn’t obstructing anything. Made sure to flush out any sediment at the bottom of tank before hooking up water hose. Meter at 296.155 before pressurizing. Opened up water valves and ran flow center pumps to circulate all water, then burped pumps to get rid of any air. After pressurizing, Meter reading 297.160, static loop pressure at 58psi. 1 gallon was added during setup.
