MarCraft’s team of technicians will ensure that your system is performing at its best before it ever gets to your location. Every system is factory tested for performance verification, which reduces any performance issues on site. With the full factory performance testing you get performance data and specifications, showing how your system is running when tested in our factory.

Factory Testing

Every MarCraft Custom HVAC System comes to you after being fully factory tested

Choosing our factory piping option allows us to test your system in-house before it ever comes to you. This reduces the risk of air leaks in the systems casing around pipe connections. MarCraft can also fully, factory wire your system to a single electric feed, which saves money on electrical installation cost. You can choose to have sound, leaking, and performance tested in our factory assembled before your system is shipped to you. This saves critical time and field labor cost on site.
