New and Used Equipment
ACSI has consulted and worked with hospitals, manufacturers, high rise residential, refineries and heavy industrial industries to name a few. Regardless of industry, we know the critical nature of getting the right boiler, burner, high temperature furnace, kiln, as well as heating and air conditioning units to meet your budget. Regardless of your choice to purchase new or used, you want your equipment to work like new and stay working with confidence.

Purchasing new equipment such as boilers, burners, high temperature furnace, kilns or other heating and air conditioning units can be too great of a financial investment for an owner or manager.
