Air Design Heating & Air Conditioning.

The state insures Air Design under workers'-comp classes for HVAC installation and service and for light-gauge sheet metal fabrication, which fits a shop that builds its own ductwork. Its electrical permits are tied to equipment: thermostat wiring, rough-in and trim for heating and cooling installs. The crew falls in the 21-to-30 band. Public-works filings between 2016 and 2022 list the Washington State Department of Commerce and Community Frameworks, with Air Design working as a subcontractor. The company says it dates to 1979, is locally owned, warranties every part it installs and honors manufacturer warranties. It also lists gas fireplace, pellet stove and wood stove service. The state lists Aaron Lindeman, Leslie Lindeman and April Anderson as principals. Air Design suits homeowners repairing or replacing a residential furnace, heat pump or air conditioner, or moving an older house off oil heat. Its focus is residential heating and cooling rather than large commercial or industrial systems, and its electrical work is the wiring that goes with HVAC equipment, so a standalone electrical project belongs with an electrician. Heating and cooling demand in Spokane runs in two spikes. The first cold snap of fall brings a rush of furnace calls, and the first hot week of summer does the same for air conditioners. Replacements and oil-to-electric or gas conversions are easiest to schedule in spring and early fall, when crews aren't chasing emergencies. Booking a furnace check in late summer and an AC check in spring keeps a no-heat call off the calendar in January, whether the house is in the Valley or out toward Deer Park or Cheney.
