Cost Savings / Payback

Custom air handling units offer significant benefits over standard commercial grade units. Average design life is increased from less than 15 years to more than 30. Average cabinet leakage is reduced from 5% of design CFM at 5" of static pressure, to less than 1% of design CFM at more than 10" of static pressure. Custom units are more flexible than standard units and offer factory piping, wiring and optional factory sound, lead and performance testing.  

Benefits of a MarCraft Custom HVAC System:

• Average design life with proper maintenance estimated at 30+ years.

• Average cabinet leakage does not exceed 1% of design CFM at over 10” of static pressure. Less leakage means more BTU’s in the building ductwork and not wasted in the mechanical space or outdoors in the case of rooftop units.

• Very flexible -- Systems can be U-Shaped, T-Shaped, L-Shaped, round, columns in the air tunnel, stack, or nearly any other shape required to fit the project requirements.

• Factory wiring and/or piping is available. This saves the high cost of field wiring/piping.  It allows for single point electrical hook-up and reduces the risk of air leaks in the unit casing around pipe connections.

• Optional factory sound, leak, and performance testing of assembled units before shipment.

• Building custom units is like having two construction sites at once.  Unit can come complete with piping, wiring, controls, etc. ready for simple installation and hook-up to utilities; you basically turn the system "on".

• MarCraft's customer gets what it wants -- not a standard assembly-line or "off-the-shelf" equipment.
  

 Don't take our word for it though; look at the cost savings of MarCraft TRUCustom™ HVAC Systems vs. Standard Equipment:

The below table is a comparison based on a roughly 100,000 ft² building in the Chicago area.

**Over the remaining 14 year service life of the standard unit the savings on maintenance and utilities alone ($19,500/year) are approximately $273,000.  Combined first year and service life savings using a MarCraft TRUCustom™ unit total in excess of $399,000.
