A new furnace is a major investment, and you want it done right. HotWire installs gas and electric furnaces in homes across Bellevue — from compact furnaces in Downtown condos to high-capacity units in large Lakemont homes. We start with a proper load calculation, help you pick the right efficiency level for your budget, handle the permits, and install the system to manufacturer specifications. Every installation includes a warranty and our guarantee that the system is sized, installed, and running correctly.
Choosing the Right Furnace
Gas furnaces are the most popular heating choice in Bellevue for their fast heat output and lower operating costs compared to electric. We install 80% and 95%+ AFUE gas furnaces from Lennox, Trane, Carrier, Goodman, and other major brands. High-efficiency models require a condensate drain and PVC venting — we handle all of that as part of the installation.
Replacing an old furnace involves more than swapping boxes. We remove the old unit, inspect and seal ductwork connections, install the new furnace with proper clearances, connect gas and electrical, install new venting if needed, and commission the system with a full test run. The old equipment is removed and recycled properly.
Furnace replacement cost in Bellevue depends on the efficiency level, brand, and installation complexity. Standard 80% AFUE furnaces start around $3,500 installed. High-efficiency 96% AFUE furnaces range from $5,000 to $8,000 installed. Premium modulating furnaces with variable-speed blowers can reach $8,000-$10,000. We provide detailed, itemized quotes so you know exactly what you’re paying for.
Many Bellevue homes built in the 1960s-1980s in neighborhoods like Bridle Trails, Vuecrest, and Tam O’Shanter have original or second-generation furnaces that are well past their useful life. We specialize in upgrading these homes — matching new equipment to existing ductwork, improving venting, and sometimes recommending duct modifications for better performance.
