Furnace Installation & Replacement in Redmond, WA

Furnace replacements in Redmond split the same way the housing does — newer Overlake systems are usually still under warranty, while Education Hill and Grass Lawn furnaces are commonly the original equipment from when the home was built.

Furnace Installation in Redmond: what's different here

Education Hill and Grass Lawn homes from the 1970s and 1980s are now due for their first full system replacement, while newer Overlake townhomes usually have compact equipment and short duct runs. Redmond homes from the 1970s and 1980s are often on their second furnace now. We size the replacement to the home rather than to the old unit's label, because many were oversized when they went in.

Permits and inspections

A furnace replacement needs a mechanical permit, and changes to the gas line are inspected too. Mechanical and plumbing permits in Redmond go through the City of Redmond Development Services. When the work needs a permit, we pull it, schedule the inspection and leave you the paperwork.

Utilities and rebates

Redmond homes get electricity from PSE, and most have PSE natural gas. Redmond homeowners may qualify for utility, state or federal rebates. We point you to the current programs for your address before you sign.
