$ Ton Coil used on a 5 ton unit
Last week I encountered a situation where a 5 ton Trane XB10 unit had been installed to replace a 4 ton Goodman unit, the 4 ton Goodman A coil was used. The home owner said unit was installed by tech engaged by his homeowmers insurance after his unit was damaged by a tree limb. The home owner said the techs did not change anything on the furnace, simply removed freon from damaged unit cut it out installed the Trane unit, charged it turned it on and left. Homeowner said unit worked fine and cooled well. Setup has been in service since March. I have seen 4 ton A coils that could be converted to 5 tons by changing the metering orfice, however the guy swears techs did not even go into basement. Whats you guys thought on this? I explained the situation to the home owner and he ask me what should he do. Now the man is retired and on fixed income. Should he just leave thing alone and hope for the best or should he try to make the insurance company replace A coil ? I in all my years in the hvac field have never encountered such a deal. What the proper thing to do? Incidently the Trane unit appears to be used was manufacured in 07 but appears to be in excellent shape.
