AirTest Turn-Key Garage Design Services

AirTest can help you design the best system for your garage including determining potential energy savings, payback and provide assistance with local rebates that may be available to help fund your project. We can also assist with finding reputable system installers if necessary. If you are interested in using these services contact AirTest and ask to talk to one of our garage ventilation specialists. Information we will need to do an initial assessment on your project includes:

  • Floorplans of all garage levels with dimensions and fan locations marked
  • Rated horsepower of all fans and their location. Energy meter readings (kW) of all fans also would be helpful.
  • Typical fan operating time per week.
  • If there is an existing CO based ventilation system, and if it is working.


From this information we can provide a payback analysis and quote on a system for you. Call or email for more information.
