Max Builder LLC.

Registered with Washington L&I in 2025, Max Builder is a new business, and the state puts the crew at one to three people, with the owner doing the work on site. The state lists Maksim Kuropatkin as a principal since 2025. The work is residential, and the company advertises seasonal HVAC service and emergency heating repair along with 24-hour availability, and describes itself as family-run. That makes it a fit for a furnace that quits on a cold night or a system that needs attention before winter or summer. A framing, roofing or large commercial project falls outside what this shop does. In Spokane, Spokane Valley and the surrounding towns, replacing a furnace, heat pump, air conditioner or water heater generally calls for a mechanical permit, and new gas lines or added ductwork usually do too. An inspector checks venting, gas connections and clearances, which matters with older housing stock and gas appliances. A licensed contractor should pull that permit as part of the job rather than leaving it to the homeowner. Ask who is pulling it before work starts, and expect an inspection to be scheduled once the equipment is in.
