Master Heating & Cooling LLC.

The state insures the business under a single workers'-comp class, HVAC-R install, service and repair, and that matches the work: one trade, done consistently. Mechanical permits matched to the licence run from 2024 into 2026, in Spokane, Spokane Valley, Liberty Lake, Greenacres, Mica and Cheney. The crew sits in the four-to-six range. The state lists Artem Sorokin as a principal since 2022, the year the LLC was formed. The company describes itself as family-owned and says it offers a one-year labor warranty, equipment and labor coverage, and a price before approved work begins. Its site lists heating load assessments, load calculations, ductwork design, dual-fuel installs and airflow diagnosis alongside routine repair. This is a residential-leaning shop that also does light commercial work. It fits a homeowner with a furnace that quit on a cold night, a family weighing a heat pump or dual-fuel setup, or a buyer of an older house who wants the heating load and ducts looked at before closing. Builders in the Valley and toward Post Falls and Coeur d'Alene can hand off rough-in and final checks. Large commercial mechanical projects, or jobs that call for a specific manufacturer's dealer program, are a different kind of contractor's work. Spokane winters set the calendar for HVAC. Furnace and heat pump failures cluster in the first hard cold snaps, when every shop's schedule fills at once, so a fall tune-up and inspection is the cheapest insurance against a no-heat call in January. Heat pumps and mini-splits have to be sized for real Inland Northwest cold, which is where a load calculation matters more than a rule of thumb. Dry, smoky summers push AC replacements into June and July; booking an air conditioner swap in spring, before the first heat wave, usually means more choice of dates.
