Delivering Excellent Workmanship and Customer Service

Systech Mechanical in Chewelah, Washington is a company that specializes in servicing and maintaining all major HVAC systems. We have been fulfilling the needs of clients in most of North Eastern Washington since 2010.

New Construction

We work closely with some of our local contractors to install new HVAC systems in new construction projects. If you are planning a new construction with one of our associated licensed contractors, we would be happy to work with you on choosing an HVAC system to suit the needs of your building. We deliver a limited one year warranty with our work and extend a free service maintenance within the first year of installation to ensure your system is still operating within standard expectations.

Service and Maintenance

Our service and maintenance technicians provide 24 hour, 7 days a week service calls for your system breakdowns. Their conscientious, friendly service is backed by experienced professionalism and training to get your system back up and running as quickly as possible. We also offer an annual maintenance package to ensure priority service and pricing for our maintenance agreement customers, striving to keep your system operating at its best.

Updating Outdated Equipment and New Additions

Today’s HVAC equipment can deliver higher efficiency resulting in a savings in your heating and cooling costs. Whether your system needs replaced due to age or malfunction or you are just looking for that higher efficiency range; we can help you replace outdated or deficient equipment with your specific space needs. When it comes to adding AC to an existing furnace, a gas fireplace in the addition, or putting a mini-split in the apartment above the garage, we have your best interests and options in mind.


We have a variety of filters and parts at our physical location for your HVAC needs. Our friendly office staff is available to help you with your purchases M-F, 7:30 a.m. - 4:00 p.m.
