You are tired of shouting over the hum of a rusty machine just to talk at the kitchen island. Swapping it for a quiet stainless steel model cuts the kitchen clatter down to a whisper and cleans the pots without a pre-rinse. The install takes a couple of hours once the unit arrives, and the best time to buy is during Memorial Day sales when appliance discounts actually drop.
Before you lock anything in, get at least two installation quotes from local plumbers or handypersons. Prices for haul-away and hookup vary wildly between big-box stores and independent shops. Comparing them keeps you from overpaying for labor on top of the hardware.
That 0% intro period is a deadline, not free money, and any leftover balance when the 15 months end will get hit with standard interest charges.
