Heating & Cooling Services in Longview, WA

Longview’s original neighborhoods — St. Helens, Olympic, Columbia, and the streets radiating from Lake Sacajawea — contain some of the Pacific Northwest’s finest examples of 1920s-1940s residential architecture. These homes were built to last, with old-growth timber framing, hardwood floors, and architectural details that modern construction rarely matches. But their heating systems tell a different story. Original heating in these homes ranged from gravity furnaces (large, ductless units in the basement that relied on natural convection) to coal-converted-to-gas systems, wall heaters, and early forced-air installations with minimal ductwork. Many of these homes have been through multiple heating system changes over their 80-100 year lifespan, resulting in awkward ductwork routing, oversized furnaces in undersized utility closets, and compromised efficiency from decades of modifications.

Retrofitting modern HVAC into Longview’s historic homes requires creativity and respect for the original architecture. Ductless mini-split heat pumps are often the best solution, providing both heating and cooling through compact wall-mounted units that require only a small hole through the exterior wall for refrigerant lines. For homes with existing ductwork (even if it’s been modified multiple times), a ducted heat pump can often be adapted to the existing system with targeted duct improvements rather than a complete rebuild. We’ve worked in dozens of Longview’s historic homes and understand the challenges of tight utility spaces, knob-and-tube wiring concerns, lath-and-plaster walls, and the need to preserve the architectural character that makes these homes special while delivering modern comfort and efficiency.
