Luis 8-4-26 Return visit to replace mitigation board systems and also repair first floor refrigeration line. After replacement of mitigation board system to system operation. I called tech support, per tech support both sensors need to get replaced. We need to come back with a2l sensors. On first floor pull deep vacuum and add factory charge plus line set. (Not Enough) I had to add total of 5 lbs 2 ounces total charge to increase sub cooling to manufacture standards. Both units are cooling. We will need to come back with two new sensors.

Luis 8-2-26 Customer called in for no cooling both units first and second floor. Customer stated they lost power when power came back on the house. Temperature went up too close to 90°. She turned system electrical off. I check system operation individually, second floor system furnace display defrost with heater operation, after troubleshooting unit found mitigation board issue. Without thermostat (removed from wall) mitigation board kept energizing cooling and heat. I bypassed mitigation door further troubleshooting, system is cooling I will talk to management about this issue and will order parts. For first floor; same issue I also found first floor system very low on refrigerant, I performed leak search, I did perform a deep leak search on indoor coil no signs of leak. I found solder connection on filter drier. I repair leak no more leaks. I did. It had enough refrigerant to completely finished repair. I added refrigerant around 390 psi. We will verify pressure when we return for

Q&A is complete and everything tested out the first floor. outdoor unit does have oil around it and seems to be slightly undercharged, but we also had a problem with the service valve leaking from the factory on this outdoor unit. Everything else checks out on all systems. We possibly may have to reinstall new outdoor unit first floor

2nd floor system. Completed quality assurance, check DIP switch settings, charge and tested out. Also checked thermostat settings nice install.

Adapted flus and gas line. Ran new condensate with ez trap and condensate pump. Adapted to existing vinyl tubing. Adapted high volt and installed new outlet and switch. Reused existing thermostat and wired in low volt with safeties. Flushed line set and connected to new equipment. Installed new A/C outdoor on leveled pad. Installed new disconnect with surge protector and wired into outdoor unit. Cleaned up work area and tested out equipment. Reinstalled existing humidifier on return. On first floor system, liquid service valve was leaking nitrogen out of the top when it was closed. Called Nathan to verify. A video of how it was leaking will be uploaded.

Estimate

Luis 6-20-25 performed 2 ac tune up, fist and second burn gas furnace with ac. First floor: Check electrical low and high, record history, check air filter 401 ok at this time. Inspect coil and blower. Check supply and repair temp 73/73 informed customer about ax not working, test drain pump is very old vinyl tubing seems to be same age, vinyl tubing very hard to run new vinyl basement is finished don’t see where drain termination location. Check outdoor unit found unit almost out of refrigerant, capacitor and contactor original to unit and showing major wear. Outdoor motor major signs of rust on shaft and motor. As I was checking indoor coil I found severe crack on heat exchanger. This is safety concern due to Carbon monoxide potentially leaking into ductwork, due to age and condition would high recommend replacing system. Second floor Check electrical low and high voltage connections and components, started ac and check supply and return air temp and flow. 19 degree split. Check d

Comfort issues on 2nd and 3rd floors. 2nd and 3rd floors are hotter than first level. Inspected home and found main return on 1st level right above system. There are returns on 2nd and 3rd levels. May be best to seal ductwork and balance system first before zoning or adding ductless.

Discussed goals and concerns with homeowner completed full energy, audit of home, and discussed solutions and next steps. Proposal to follow and then potentially schedule HVAC visit to look at options for the third floor.
