Built in 2008, this home is newer than about 96% of the homes around it. That usually means less pressing condition work and more genuinely optional improvement, which is reflected in the priorities above.
For scale, the largest project on this plan is about 12.4% of the home's estimated value. A useful rule of thumb: condition work that protects the structure is worth doing almost regardless of that ratio, while discretionary work is easier to justify at the lower end of it.
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.
