Winter reality
Single-digit cold snaps and older housing stock make a clear diagnosis urgent. We focus on safe, reliable heat first, then explain the repair path in plain language.
Spokane winters are serious. Temperatures routinely drop below 20°F, and stretches of single-digit cold are common from December through February. When your furnace fails during that kind of weather, it stops being an inconvenience and starts being a safety issue.
We serve homeowners across Spokane, including established neighborhoods like Browne's Addition, the South Perry District, and Kendall Yards, as well as surrounding areas throughout Spokane County. Whether your home was built decades ago or recently updated, we diagnose the root cause of the problem before recommending any repair.
Spokane's older housing stock often means aging furnaces running harder than they should. Homes near Manito Park and Riverfront Park frequently have systems that have cycled through 15 or 20 winters. That kind of wear shows up in specific, predictable ways, and knowing what to look for is how we fix it right the first time.

It covers a complete, safetyfirst evaluation of your furnace: combustion, venting, electrical, controls, and mechanical components. You'll receive a clear explanation of what we found and your repair options before we do any work.
Shortcycling like this is often a dirty flame sensor, a tripped highlimit switch, or an airflow restriction. Each cause has a different fix which is why we diagnose before recommending anything.
It can be. A yellow or orange flame indicates incomplete combustion, which can produce carbon monoxide. We treat this as a safety concern and inspect the burner and heat exchanger thoroughly.
We'll give you an honest evaluation. If repair is the right call, we'll explain why. If the system is at a point where replacement makes more sense longterm, we'll walk you through that too without pressure either way.
We test both. A thermostat issue and a furnace control board fault can look identical from the outside. Proper diagnosis tells us exactly where the signal breaks down.
Annual maintenance before the heating season is the most effective step. It catches worn components ignitors, flame sensors, belts before they fail when you need heat most.
If this feels urgent or safety-related, calling is the fastest option.
