Six Mile SC – HVAC Services

Need to return Wednesday

Replaced 2 ton ac/coil and furnace. Swapped from an 80% to a 90% furnace. Installed new thermostat, pad, disconnect, whip. Installed a 16x25x4 aprilaire filter. Installed condensate pump and pulled new thermostat wire from inside to outside with the vinyl tubing. Ran new 2" PVC flue pipe. Verified operation in heating mode. System is operational at time of departure.

System is not cooling due to being frozen solid from the evaporator coil up the line set into the compressor. It hadn’t made it to the compressor yet, but the evaporator coil line set is solid ice. System has gas heat so I applied gas heat to get the system defrosted so it could be diagnosed for why it’s not cooling. System is likely low on charge. The furnace was replaced recently, but they did not change the evaporator coil and AC outdoors on the roof. System is running, but this very well should’ve been replaced when the furnace was replaced to get everything matched up good. Please note that I will need to wait for the defrost time, but I am waiting on site so it can be diagnosed and get the cooling back on as soon as possible without having to let it naturally defrost and causes a long weight on the cooling. System is likely low on refrigerant. That will get a full diagnostics once I get it defrosted After fully defrosting, I did charge the system with proper refrigerant of 3.7 l

2.5-ton heat pump split system (attic installation) 20x20x4 April Aire Filter 2 float switches New disconnect and whip New thermostat New pad Verified system in cooling mode System is operational at time of departure.

Replaced 2-ton gas package unit. Installed new pad, whip, and thermostat. Reconnected gas line and built new flashing. Verified operation in heating and cooling. System is operational at time of departure.

The system provision works stage one and stage two heating is working properly with the new thermostat that is up. The equipment that’s having the issue right now is totally separate system for next-door. Right now, that store is closed, but we need a separated work order for the Nigh Eye Group. There has been ongoing work done for Visionworks and the equipment that supplies the heat to the main part of the store. This is a 7 1/2 ton that has been needing replaced, but we are rebuilding the gas heat portion as it goes out, but very much pushing for new equipment the next round on Visionworks. But to retouch the system in question here is for next-door. There is a shared area with this equipment that is partially inside of the rear rooms of vision works and is currently on and working and there is a satisfied thermostat at 72° for the next-door eye group. Vision Work is partners with Nigh but they work order needs to be separated and put in for NIGH and it will be completely separate eq

New Pad, Whip, Disconnect, Thermostat, Warranty 10/1/1. Replaced 3ton heat pump air handler. Installed new pad, new disconnect, new whip, new Wi-Fi thermostat. Verified system in cooling. System is operational at time of departure.

45/5MFD capacitor installed on 4 ton Goodman

Installation of new 35/5 mfd capacitor on the heat pump for the compressor and condenser fan motor and a 7.5 MFD on the blower motor in the air handler

Installation of new 60 amp service disconnect and serve protection in the crawlspace

Installation of new thermostat to replace the failing stat that is currently up that has been under heavy usage for quite some time. Installation of new inducer housing with draft motor to replace the broken draft motor where the wheel has freed itself from the motor due to rust. This will require approximately two hours of labor.

Removed and replaced 2 ton duct system. Installed 15 ft of hard pipe trunkline. Reconnected 6 supply runs. Upsized and replaced return as well return pipe. Replaced square to rounds and resealed flashing to package unit.

Charge system 1 pound of 410 a. sub cool super heat is off. Pressures are low for the ambient temp outdoors.

Installed drain plugs in evaporator coil that were missing from initial installation.

Repairing the end of the flex run good enough to repair without replacing the full run. This was almost inaccessible due to how low the crawlspace is on the front corner of the house, but ensuring proper secure and seal of the 6 inch flex run to the boot of the supply vent. Screws straps and tape was used. Please note that it looks like plumbers. Just literally jerked it out of their way tearing the end of the flex run off and leaving it sealed to the boot. Everything had to be removed in the end of the flex repaired before connection.

Replaced PTAC unit.

Installation of 60 amp circuit from the outdoor panel to the heat pump package unit. This will require 60 amp breaker to replace the current 40 amp breaker and the outdoor panel and wired to the 60 amp breaker inside the unit for the 15 KW heat kit. -the 60 amp breaker installed with designated circuit of number six wire was for dedicated heat kit power with its own breaker coming from the panel to the unit breaker which is 60 A. System must have its own designated power for heat pump and auxiliary/emergency heat. Heat pump designated power 30 amp, auxiliary heat/emergency 60 amp.

Installation of baffle kit for extreme temperatures to protect the unit running in AC mode year-round to maintain the 65°

Installation of new one and a half ton mini split outdoor unit and evaporator coil blower head for the room where the data is stored to maintain 65° year-round

System is making a noise and after eliminating the fact that it’s possible it was the condenser fan. I found that it was actually the reversing valve. The reverse and valve are not opening all the way up in heat mode and is screaming by and we have gas being trapped as well because the line set got so hot that it melted the armor flex off of it and coated the copper like it was spray painted black. I will be ordering a new reverse in valve with new coil pack and try to see if the new coil pack will open and close the reverse and valve all the way both ways for both heat and cooling cycles as an attempt to fix the issue before changing the reversing valve altogether. System is performing properly, but with a malfunctioning reversing valve. Model and serial number are uploaded to documents.

Two pressure switches, two high limit switches on the blower and one rollout switch per stage above the burners. Belt replacement for stage two blower and a very much needed burner cleaning for both stages.

The system here is a mini split, the model is 2014, which is impressive due to it not being built for what it’s been used for. It is not ideal to run in cooling mode year-round due to the extreme temperatures within the winter and trying to maintain 65° inside of a data room. Key factors need to be taken in to consideration of baffles being put in front of the unit to keep wind off the unit during the winter time as well as consideration to replace the mini split here now with a system that is built for extreme temperatures, which will hold up to the fact that it runs in AC year-round. Low outdoor ambient kits installed from day one, baffle kits to keep the wind off the unit outdoors installed from day one and the system itself built for those type conditions is key factors in considering replacing the system. Having said that the 2014 system is going on 12 years old of extreme use. We’ve had 14 winners where this thing has struggled to maintain cooling mode with outdoor cold temperatu
