MJC is a manufacturer for HVAC products - we have Air rotation, self contained units, custom equipment, modifications, and coatings

Built for your specific job requirements, MJC Custom Air Handlers are designed to provide the highest performance for challenging applications.

MJC’s engineering team will take your challenging application requirements to help design the best custom air handler. MJC has manufactured custom air handlers for over thirty years and met the most challenging specifications to help you meet your customers needs and goals.

Replacement Market & Perfect Fit

One of the most popular custom air handlers MJC manufacturers are designed for modular construction. Designed to fit through doorways, corridors and freight elevators, our modular cassette design allows one to install new equipment into a mechanical room without tearing down doorways, walls, or removing windows.

MJC Modular Air Handlers ship in individual cassettes to be installed in the most challenging spaces. Typical modular air handler installations are designed for “weekend changeouts” so that the building owner has the space or floor operating by Monday morning.

Designed to meet your needs

MJC custom air handlers are engineered and designed outside of the standard factory product. Where large HVAC OEMs have standard catalog options, MJC provides a solution to meet your needs and goals. Typical applications and designs outside of catalog OEMs may include:

  • Large CFM (30,000+ CFM)
  • Specific Airflow arrangement
  • Higher Capacity Heaters
  • Direct Fired Gas Heaters
  • Customized Footprint
  • Fan Redundancy
  • VRF
  • Advanced Filtration
