A common mistake when buying a new AC is assuming higher tonnage equals better cooling. In humid climates, an oversized unit actually ruins your indoor comfort because of these 2 things:

• Short Cycling: Oversized ACs cool your house too fast and shut off quickly.
• The Humidity Trap: Dehumidification takes time. Short run cycles leave moisture in the air. It can also create the perfect environment for mold.

If your house feels cold but swampy, your unit is likely oversized or suffocating on bad ductwork. Hope this helps anyone comparing quotes!
