Furnace Repair in Trenton: what's different
Furnace Repair in Trenton is shaped by local conditions. Aging boilers: Many homes run decades-old cast iron boilers that need relief valve, expansion tank and combustion checks to stay safe.
Rowhouses and twins usually heat with gas boilers and radiators or older gas furnaces in the basement. Cooling comes from window units or retrofitted systems, and many homes have limited space for ductwork or outdoor equipment.

Another local pattern worth mentioning to the tech: limited cooling options. Without ducts, window units are common. Ductless mini-splits are a popular upgrade that improves comfort and efficiency.
