Duct heaters boost air temperature for any forced air system. It provides additional heat for cold room. Ground Source Heat Pump is provided for boost or backup. Duct heaters resists corrosion/oxidation while protecting resistance coils against contamination. It maximize dielectric strength, heat transfer and life. It permit easy service and reduce downtime. It keeps the wiring cooler and reduces heat loss. It ensures cooler terminations. It accepts an optional type J or K thermocouple for accurate sheath temperature sensing. Duct heaters prevents element sagging or deformation in various mounting positions. It easily bolts to the duct wall. It assures MgO density that eliminates hot spots and meets a wide variety of KW demands.

Ductless air conditioner, also called a mini-split system, has two major components: a unit mounted on an inside wall that delivers cool air to the room and a unit mounted on the outside of the house. A pair of refrigerant lines runs between the two, one delivering electricity, the other taking away condensate (water). The system also has thermostatic control and a variable quiet blower. With a ductless system, simple copper tubing and electrical wiring to indoor units connects a separately installed outdoor unit. Refrigerant is pumped from the outdoor condenser coil and compressor through the tubing to the indoor unit or units. A fan then quietly distributes cool air drawn across the unit's evaporator coil. Ductless split air conditioning system consists of four major components such as the condensing unit, which contains the compressor, is located outside the building; thin refrigerant lines, usually copper tubing, connects the outdoor unit to the indoor unit or units; the indoor unit or units, each with a fan, come in a variety of shapes and sizes and can be wall or ceiling mounted and a hand-held wireless remote or wall monitor controls the entire system.
