About

HZA Engineering, LLC is an Alaskan Mechanical and Electrical Engineering firm with 20 years of experience providing effective and economical engineering solutions for facilities in Alaska’s unique and challenging environment.

HZA engineering has fine-tuned its expertise over decades of working in Alaska’s variable and unforgiving environments.

The state spans a wide range of environments from the Interior, with its massive temperature fluctuations to coastal areas, fraught with high wind and relentless precipitation. Energy costs and system parameters will vary dramatically for a similar building located in Barrow versus Bethel and HZA engineers have the experience to know the differences demanded by each and how to provide the most cost effective solutions not matter what the location demands.
