Heating, cooling and home-energy projects share one trap: they are quoted as a single lump sum for what is really three separate purchases — equipment, installation labour, and the ductwork or wiring the equipment depends on. Our guides unbundle all three. Where a system is sized in tons, kilowatts or watts, we verify the unit price first and build the totals from it, so a quote can be checked line by line rather than taken on faith.
This category also carries a standing warning for 2026: several federal home-energy tax credits that installers advertised for years — including the 25C equipment credit and the 30% residential solar credit (Section 25D) — ended for installations completed after December 31, 2025. Every guide in this category states plainly which incentives no longer exist and points you to the state and utility programmes, and the DSIRE database, that still do.
Every figure in these guides is an estimate drawn from published data and checked against at least two sources — see how we research, and the disclaimer for what these numbers can and cannot do.
