About Fischer Heating and Air
Fischer Heating and Air in Mountlake Terrace earns a 4.9-star rating across 138 reviews, reflecting over four decades of concentrated HVAC expertise in the Seattle metropolitan region. The company holds EPA and NATE certifications, validating technician competence in refrigerant handling and system installation standards. Serving communities from Lynnwood and Bothell north to Everett and Stanwood, along with Seattle neighborhoods spanning Ballard to Capitol Hill and eastside cities including Bellevue, Kirkland, and Redmond, the operation maintains broad regional coverage. This contractor handles both residential and light commercial projects, providing installation, maintenance, and emergency repair services for heating systems, cooling equipment, and heat pump technology.
What distinguishes Fischer Heating and Air is their documented partnership with Mitsubishi variable-speed heat pump systems, a brand known for whisper-quiet operation and energy efficiency in Pacific Northwest climates. The company operates as part of a family enterprise originating with Fischer Plumbing in 1977, expanding over time to include restoration, electrical, and heating and air divisions under unified ownership. This integrated-services model allows coordination across trades when projects require multiple disciplines, though each division maintains specialized crews. All service calls prioritize transparent pricing with no surprise line items, and technicians arrive in marked vehicles wearing company identification.
Homeowners highlighted specific technicians in their reviews, with Pat receiving repeated mentions for consultative sales approaches and accurate scoping during estimate visits. One reviewer described a two-day furnace-to-heat-pump conversion where the crew arrived at 8am, maintained clean workspaces throughout, and completed the installation before 2pm the following day. Another client noted same-day diagnosis of an undersized outdoor condenser unit that was struggling to meet cooling demands, with the technician explaining the Root cause and presenting right-sized replacement options. Alex and his installation crews earned recognition for efficiently coordinating with on-site electricians during complex retrofit projects, and multiple reviewers reported their systems operating without post-installation issues.
