My central Rialto home has small ducts. Do I need to replace them with the AC?
Usually upsize, not full replacement. Pre-1980 Rialto homes often have undersized return ducts that strangle modern variable-speed blowers. We measure return static pressure during the quote walkthrough. Upsizing or adding a second return run typically costs $400-$1,200, separate line item on the install quote.

How do I know what size AC I need?
