FURNACE INSTALLATION

Furnace Installation in Tacoma & Seattle

New high-efficiency furnace installs, replacements, and dual-fuel systems — sized right, installed honestly, and priced fairly for homeowners across the Puget Sound area.

Is It Time for a New Furnace?

Most furnaces last 15–20 years when they're maintained well. If yours is past that age, needs frequent repairs, or simply can't keep every room warm, a new furnace installation often saves more than it costs.

We install high-efficiency gas and electric furnaces for homes in Tacoma, Seattle, and the surrounding Puget Sound area. Every install starts with a proper load calculation so your new furnace is neither too big nor too small — because the right size is what delivers real comfort and efficiency.

Whether you're replacing an old system, finishing a new build, or switching from baseboard heat to forced air, The HVAC Rat will walk you through the options and quote the job upfront.

Furnace Installation Options

Gas Furnace Installation

High-efficiency natural gas furnaces from trusted brands. We handle venting, gas line coordination, combustion safety, and code-compliant installation.

Electric Furnace Installation

A clean, electric-only heating option ideal for homes without gas service or for pairing with solar and heat-pump systems.

Furnace Replacement

Remove your old furnace and install a new one with proper duct connections, drain lines, and safety testing — all in one clean visit.

Dual-Fuel Systems

Combine a high-efficiency furnace with a heat pump for the lowest possible heating cost: electric heat most of the year, gas backup on the coldest nights.

Benefits of a New Furnace

Up to 98% AFUE

Modern high-efficiency furnaces turn almost all of their fuel into usable heat, so less energy is wasted up the flue.

Lower Monthly Bills

Replacing an older furnace with a high-efficiency model can noticeably cut your winter heating costs.

Even, Reliable Heat

Variable-speed blowers and two-stage burners keep temperatures steady and eliminate hot-and-cold swings.

Better Airflow

A properly sized furnace moves air through your ducts at the right rate for comfort and efficiency.

Warranty Protection

Manufacturer warranties require correct installation. We install to spec so your coverage stays intact.

Right-Size Guarantee

We run a real load calculation — no guesswork — so your furnace is neither oversized nor undersized.
