Cambridge is a heating market. Furnace, boiler and heat pump calls carry the year, and the cold months bring the emergency jobs. In 2025 the thermometer hit 90°F or more on 14 days and dropped to freezing or below on 112 nights; the hottest day reached 102°F and the coldest night 2°F. Rankings take 60 to 90 days to move, so the work for winter no-heat calls starts in August and September.
