I recently upgraded my air handler to a variable speed York (4ton). It was installed this week and the tech did an outstanding job installing and hanging the unit.. a work of art and the unit runs great
The unit I had was undersized and the duct work was incorrectly sized as well.
I was hoping someone could tell me the operational differences I can expect with a variable speed unit.
So far it runs on a high speed only. It will slow down when the fan is put in the on position and room reaches temperature and the compressor kicks off. Thx BDX
