One company on both meters
The city's draft utilities chapter for its 2026 comprehensive plan says Avista provides the electricity and also supplies natural gas to customers in Liberty Lake. So the gas furnace and the AC condenser outside answer to the same utility.
That makes comparisons easier if you are weighing a high-efficiency gas furnace against a ducted heat pump with gas backup. Both rates come from the same bill, and a contractor can work from one set of numbers.

Who signs off on the work
Liberty Lake does its own building permitting through its Planning, Engineering and Building Services department rather than leaving it to the county. The city has adopted the 2021 International Codes, and its online permitting portal handles permit status, payments and inspection requests.
When a contractor quotes a furnace or central AC replacement here, ask whether the price covers the city permit and who books the inspection through that portal.

If you smell gas
With Avista supplying gas across the city, its safety steps are the ones to follow: move away and upwind, skip light switches and lighters, and once clear call 911 and then Avista at (800) 227-9187. Furnace repair comes after the all-clear.
