My contractor says that he will NOT reconnect heat recovery line (from a 15 year old unit) while he is replacing this to a newer 14 seer veriable speed carrier (model 24abr348a003
Reason he states that, with newer systems like this, heat recovery line is not of much advantage and doesn't save in electricity cost.
Is he right? or he just cutting corners?
Please answer as soon as possible as I've not signed the contract yet.
