T5 Enterprises LLC.

Washington L&I lists the business under the HVAC/refrigeration specialty, and the state insures it for HVAC-R install, service and repair along with light metal goods fabrication, the kind of sheet-metal work that goes with ductwork and fittings. On the residential side, Spokane County records show a residential mechanical permit in Greenacres in 2024. The state lists Nathan Thorton as a principal since 2022, the year the business was established, and puts the crew at one to three people, with the owner working on the job. That makes T5 Enterprises a fit for a general contractor or agency that needs a small, registered mechanical sub, including on prevailing-wage work. A homeowner in Liberty Lake, Spokane Valley or Greenacres wanting a furnace, heat pump or AC installed or repaired can also deal with a small local shop directly. It's a mechanical and refrigeration outfit, not an electrical contractor, and it runs on trade relationships more than consumer marketing. Around Spokane, replacing a furnace, adding a heat pump or central air, or running new ductwork or gas lines generally calls for a mechanical permit, whether the house sits in the City of Spokane, Spokane Valley or unincorporated county. The permit brings an inspector out to check venting, gas connections and equipment setup, which matters in a heating season this long. Expect the HVAC contractor to pull that permit in its own name; it ties the work to a registered business and keeps the record clean when the house sells.
