HVAC Experts Who Know Troy's Homes

Troy is one of the most architecturally rich cities in the Capital Region — and one of the most challenging for HVAC work. The city's extensive inventory of 19th-century brownstones, Victorian row houses, and pre-war multifamily buildings creates HVAC situations that require genuine expertise and creative problem-solving.

Many Troy homes were built before central air conditioning existed and rely on steam boilers, hot-water radiator systems, or gravity furnaces for heat — with no existing ductwork for cooling. ALJ technicians are experienced with all of these systems. We repair and maintain aging boilers, replace obsolete equipment with modern high-efficiency alternatives, and install ductless mini-splits as the ideal cooling and heating solution for homes without ductwork.

From Lansingburgh in the north to South Troy along the Hudson, we service every corner of this city. Same-day service is standard, and we bring the honest pricing and 4.9-star reputation that Troy homeowners have come to rely on since 2018.
