Olson Energy Service

Olson Energy Service has earned a 4.8-star rating across 373 customer reviews in Seattle, reflecting nearly three decades of consistent service in the Pacific Northwest. The company handles residential heating and cooling systems, from emergency furnace repairs to complete heat pump conversions. Technicians arrive in marked vehicles with professional demeanor, and each project receives a written estimate before work begins. The business maintains an A+ rating with the Better Business Bureau and participates in regional utility rebate programs that help homeowners offset upgrade costs.

What distinguishes Olson Energy from Seattle's crowded HVAC field is their methodical approach to diagnostics and transparent pricing. Rather than recommending unnecessary replacements, technicians explain each diagnosis in plain language, the reviews specifically praise no pressure sales interactions. They specialize in aging systems, successfully servicing furnaces past 25 years old rather than defaulting to complete replacements. The company also handles dual-fuel setups and offers same-day appointments for urgent situations, with one reviewer noting they arrived four minutes early to a scheduled call.

Customer reviews repeatedly mention technician Chris by name. Jackie Thompson called Chris super fast when re-programming her thermostat after a heating issue, praising his efficiency with both thermostat adjustments and furnace maintenance. Lance White similarly noted Chris diagnosed a dual capacitor and fuse failure on his AC unit, achieving same-week resolution. Another review described Chris as knowledgeable when handling a complex oil-to-heat pump conversion project, and the crew left the home as clean as they found it. PScott Cummins noted that Olson Energys original furnace had run for 30 years, and the replacement install took less than half a day.
