Question DetailsAsked on 5/25/2017

I have a Goodman 2 ton ac unit will the remaining parts including the blower be compatible with a 4 ton unit ?

If I replace my two-ton unit with a 4-ton unit and keep the old air handler would it be compatible?

Do you have the same question? Follow this Question

In a word - no. The copper tubing between the elements commonly can handle an upgrade like this, but everything else is sized for the rated energy transfer capacity - the evaporator and condensing coils will be grossly undersized, as will the outdoor unit fan and the air handler fan.


In rare cases some manufacturers use the same air handler and blower motor for different sized units, but for a 100% increase in cooling capacity I would seriously doubt the fan will be compatible - and certainly not the coil.


The otehr thing you are up against is new A/C units have to be rated for energy efficiency as a system - so it is basically illegal for an installer to scab together parts to make a unit - it has to come from the manufacturer as a system with all components tested to achieve its rated SEER rating.

One thing I did not mention - even though the tubing may be able to handle the greater cooling capacity (because only a couple of standard sizes are usually used), that was not meant to imply that the old ltubing should be left in place if it can readily be swapped out without tearing into the building a lot - because otherwise, by leaving old tubing in place is leaving an invitation to blame any leak on it, justifiably or not, which might affect your warranty coverage.
