Built for the Inland Northwest

Mainstream’s identity is rooted in the communities it serves. Built in the Inland Northwest for the Inland Northwest, the company operates independently rather than functioning as a national chain or subcontracting intermediary. Every technician visiting a customer’s home is a Mainstream employee, licensed in Washington or Idaho as applicable, background-checked and drug-tested. Employees receive company benefits and opportunities for professional advancement, supporting a consistent standard of service. Mainstream is also bonded and insured, giving homeowners additional confidence when scheduling repairs or installations. This employment model allows the company to maintain direct responsibility for its technicians, workmanship and customer experience.

“Mainstream is fantastic. They sent several crews to ensure they could complete the replacement of our full electric system in 1 day. They were friendly, efficient and worked well together. Our dog loved them too!!” – Terry C.

Reliable Heating When Winter Arrives

Cold weather places considerable pressure on residential heating systems, particularly when furnaces operate continuously during extended periods of freezing temperatures. Homeowners seeking furnace repair in Spokane can turn to Mainstream for professional diagnostics, maintenance and repair services designed to restore dependable heating. Technicians evaluate equipment performance, identify malfunctioning components and explain recommended solutions before proceeding. The company also handles heating system installations and replacements when existing equipment becomes inefficient or unreliable. Addressing unusual noises, inconsistent temperatures or frequent cycling early can help prevent unexpected breakdowns. Mainstream’s upfront pricing approach gives customers an opportunity to understand service costs before authorizing repairs.

Comfort Extends Beyond Temperature

Maintaining a comfortable home involves more than keeping rooms warm in winter and cool during summer. Ventilation, filtration and humidity management also influence indoor air quality, particularly in homes where windows remain closed for extended periods. Mainstream offers heating and cooling services that help homeowners maintain properly functioning HVAC equipment while addressing concerns about airflow and filtration. Routine system maintenance can identify dirty filters, restricted airflow and equipment problems that affect overall performance. Technicians can also discuss appropriate solutions based on a home’s existing equipment and household needs. These services support a healthier, more comfortable living environment while helping heating and cooling systems operate effectively.

“Great service and the team worked late to get my new system up and running before the 4th of July weekend! The installation was very professional and so much better than what I had before! They spent the time to properly clean up after as well!” – Joshua F.

Six Guarantees Support Every Service

Mainstream distinguishes its service approach through six customer guarantees covering important aspects of the homeowner experience. Its upfront pricing guarantee establishes clear expectations before work begins, while the technician guarantee reinforces confidence in the professionals entering customers’ homes. The satisfaction and installation guarantees address service quality and completed equipment installations. Its leak guarantee provides additional reassurance for applicable plumbing work, while the “no backup” guarantee addresses qualifying drain and sewer services. Together, these commitments establish accountability across the company’s electrical, heating, cooling and plumbing offerings. Mainstream also provides a one-year labor warranty alongside full manufacturer parts coverage, subject to applicable warranty terms.

Mainstream has received more than 5,700 Google reviews, maintaining an average rating of 4.8 stars. That substantial review history gives prospective customers an opportunity to evaluate experiences involving technician professionalism, communication, scheduling and completed work. The company’s locally employed workforce and established service guarantees provide additional reasons for homeowners to consider its services.
