Question 4

How often should I service my HVAC system in Medfield's climate?

Boston has cold, snowy winters (22°F lows) and warm humid summers (82°F highs). Heating dominates seasonal demand, but humid summer heat drives meaningful cooling loads.

Many Medfield contractors offer annual maintenance plans that bundle both visits at a discount.

Accepted Answer
