Today I arrived on site to address the reported issue. Findings: Identified multiple dye leaks within the AHU Evap coil. Determined the Evap coil requires replacement. This equipment services the AC system on the 1st floor. Upon arriving at the property, I explained to the client about this day's visit with us. The client directed me to the basement where the AHU is for the 1st floor. I immediately proceeded to check the eco coil for dye leaks. I found multiple dye leaks in the AHU's evap coil. I proceeded to inspect the lineset of the dye leaks door system. I didn't find any dye leaks in the system lineset. I proceeded to check the condenser coil for dye leaks. I didn't find dye leaks in the condenser coil this time. I showed and explained to the client about the diagnosis of the system in relation to dye leaks. I presented you with an estimate of the cost of installing a new evap coil for this unit. I also informed the client that it is possible that this system is no lo
Today I arrived on site to verify the AmeriStar AHU in the basement and the Trane condenser unit in the right side of the house to trace the dye leaks. Initial Assessment: Investigated a reported dye leak in the 1st floor AC system. Leak Inspection: Located possible dye leaks within the Evap coil. Note: The leak confirmation was not definitive. When I arrived at the property, the client gave me access to the one where the AHU is installed in the engine room. I proceeded to verify the AHU Evap coil for visible dye leaks. Apparently some samples possibly of Dye appear but they are a little confusing. It is necessary to let the system operate for a longer period of time to recheck the dye leak. I didn't ensure that the small dye samples are 100% visible.. I suggest that the operating system be given more time to return at another time to identify that the leak is present in the Evap coil or in some other part of the system. I proceeded to inspect the condenser unit coil. I didn'
Upon arrival spoke with customer. Customer was experiencing error code e7 @ indoor head for living room space. Customer informed me that her kids are home and may have messed with the settings for the basement system. Customer system is x1 Mitsubishi condenser body x2 indoor head. It was explained that the error code e7 is generally indoor outdoor communication error when x1 indoor is set for a different feature. x1 calling for cooling while the other is set to heat or vice versa. Creating a mode conflict. Explained that a faulty sensor, wiring issues and or a bad control board could have the same effect. Customer system was ran and check to be operational after settings @ control was corrected. Cycle system on/off no issues. Ran and monitor operation for 15-30 minutes no issues. System is up/ running and left operational @ this time.

Service call for system still not working after leak repairs. This is a Mitsubishi system with two ducted air handlers. On arrival customers were not home but I was told by the mother in law that the upstairs is not cooling and that the error code 1501 would pop up saying the system is under charged. Spoke to Mitsubishi tech support case# 812986. We noticed that when only running the 2nd floor system the suction pressure will lower to 15 psi with a head pressure of 275 and the system will start to freeze up indicating there is a restriction at the branch box for the 2nd fl system. Solution would be either to replace the branch box or we could hook up the lines for the 2nd floor unit to the 3rd port on the branch box that was not being used. This was explained to the customer and that there is not 100% guarantee that it would work but there is a possibility that it would with out changing the branch box. Customer agreed on the set labor price. System was pumped down the lines at
Return to fix leaking coupling at condenser. All of the refrigerant was reclaimed from the system and the coupling at the condenser was cut out and a fixed. System was pressure tested and more leaks were found both at the branch box and at the 2nd floor air handlers. All of the connections that were leaking had couplings that had to be cut out and re flared. After repairs system was pressure tested again and system held pressure for 45 minutes to and hour. A vacummed was pulled and system was recharged with factory charge at 11lbs of 410a. Called tech support to check proper setting both at condenser and branch box dip switches were changed at outdoor condensers. System was monitored and is back up and running. Supply temperature is around 50-55 degrees repair is completed https://visionshare.xoi.io/?id=ms0ed132a1-575d-i184-39cb446782d2-uF83-4ac3c2bcbcfc
