5 ton Unit 4 ton A coil
At the local hvac tech coffee stop there was quite a discussion going on. One of the group was going to install a 5 ton Trane unit to replace a 4 ton unit where compressor had failed. There were varying opinions, the general consensus was if he is careful and charges system correctly he can use the 4 ton A coil without problems. I disagreed but got little support anytime I have encountered a mismatched setup like this, there has been nothing but problems.Whats the genral take on such a set from the experts out there ?
