Question 3

Do I need a licensed HVAC contractor in New Jersey?

Accepted Answer

Question 4

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

Accepted Answer

Edison sits in Middlesex County in central New Jersey's humid continental zone, with hot, humid summers reaching 86°F and cold winters dipping to 24°F. The 27 annual days above 90°F drive steady cooling demand, while cold-season temperatures make heating systems essential from November through March. 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 South Plainfield contractors offer annual maintenance plans that bundle both visits at a discount.
