Lewiston Housing Stock
The median Lewiston home dates to 1957, according to the Census ACS. That makes the typical house about 69 years old. Houses that old often still have duct runs sized for an old coal or oil furnace and 60- or 100-amp electrical panels. Both can add cost when new equipment goes in. Owners live in 50.3% of occupied homes, roughly 7,900 households. The median home value is $214,200, and median household income is $56,558. We use both figures to adjust labor and pricing for this page.
NOAA storm reports for Androscoggin County show 3 hail days and 12 days with damaging thunderstorm winds over the six years from 2020 to 2025. The largest hail reported was 1.5 inches across. Storms here are more likely to cause power surges than coil damage, so a surge protector on the outdoor unit is worth the small cost. In Lewiston, 18.2% of residents are 65 or older. For older adults, a house with no heat in January or no AC during a heat wave is a medical risk. Mention it when you call, since many companies put those calls first.
