Your Newport Heating and Cooling Experts
The federal minimum efficiency standards for new AC equipment changed in 2023, and they vary by region. Delaware falls in the southern efficiency region, meaning new AC installations in New Castle County must meet the 15 SEER2 minimum — not the 14 SEER2 that applies in northern states. Higher-efficiency equipment costs more upfront but reduces operating costs over the system's life. In Newport's climate with its extended cooling season, the payback on higher SEER2 equipment comes faster than it would in a market with a shorter AC season.
New Castle County's mixed-humid climate means both heating and cooling systems are load-bearing. An AC that underperforms in August and a furnace that struggles in January aren't unrelated problems — they're the result of the same deferred maintenance pattern that costs Newport homeowners more over time.
The combination of 2,480 annual cooling degree days and 2,900 heating degree days means Newport homeowners depend on both systems across the year. New Castle County's housing stock, with a median construction year around 1976, contains a large inventory of equipment due for evaluation or replacement.
