Question 3

Do I need a licensed HVAC contractor in New Hampshire?

Question 4

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

Accepted Answer

Southern New Hampshire has cold, snowy winters (20°F lows) and warm, humid summers (82°F highs). Heating dominates the long October-to-April season, with humid summer stretches driving real cooling demand. New Hampshire has no statewide HVAC license, so local permitting governs. Most HVAC manufacturers recommend twice-yearly tune-ups — a cooling check in spring and a heating check in fall — to maintain efficiency and warranty coverage. Many Andover contractors offer annual maintenance plans that bundle both visits at a discount.
