I want to replace my 2 1/2 ton ac unit with a 4 ton. Will I have to replace the duct work, etc. in order for this to work?

RE: upgrading ac unit


Yes, you should scrap old ductwork and install new correctly sized and insulated properly.

You will also require a matching new furnace correctly sized with a 4 ton rated blower along with matching evap coil for the new 4 ton condenser.

Correct sizing and a completely matched system is mighty important.
