Built in 1960, this home sits mid-pack for age on the surrounding blocks — older than roughly 48% of its neighbors. Expect the first wave of replacement work rather than the last.
Oversized equipment is a real and common failure. A unit that is too large cools quickly, shuts off before it has removed humidity, and short-cycles itself to an early death. If a contractor sizes by square footage alone rather than a load calculation, keep looking.
Worth asking whoever quotes it:
Expect it to take: A straight equipment swap is usually 1–2 days; adding or reworking ducts extends it to 3–5.
These figures come from aerial imagery, county records and this parcel's measured geometry. They cannot see inside the house, so they do not know the condition of your wiring, plumbing or insulation, whether previous work was permitted, how a contractor would get equipment to your yard, or what you would choose in materials and finish. Any of those can move a real bid substantially in either direction. Treat this as a well-informed starting point for budgeting, and let a site visit settle the number — that part is free.

They are planning estimates, not bids. Cost comes from the home's measured roof footprint and lot geometry combined with current regional pricing; savings use current utility rates. A licensed local contractor confirms the real figure at no cost.
Each has its own plan, and the numbers differ — roof size, lot, age and condition all vary house to house, which is the whole reason we measure them individually rather than quoting a street average.
