Who we are

Omni Mechanical Inc. was founded by brothers Tom and Tim Mitchell after more than 50 combined years in HVAC-R with Pacific Northwest companies. Between us we’ve worked residential new construction and replacement, every kind of commercial building, restaurants, industrial and manufacturing plants, and large-scale refrigeration.

We built the company around two things: the people who do the work and the experience our customers have. That means we always have an answer, we explain your system in plain terms, and we stand behind what we install.

About 80% of our work is commercial and 20% residential. We run both a service team and an installation team, so the company that installs your equipment is the same one that maintains it.

 Trustindex verifies that the original source of the review is Google. Finding a company that genuinely stands behind its work is rare. Omni exceeds every expectation.

They are been honest, professional, and committed to doing the job the right way. They communicate clearly, follow through on every promise, and never cut corners. It's obvious they take immense pride in their craftsmanship, and that level of dedication shows in everything they do.

What is most impressive goes beyond the quality of their work, it is their integrity. They are the kind of people who treat your project as if it were their own, offering honest recommendations and making sure every detail is right before they consider the job complete.

If you're looking for a mechanical company you can trust completely, this is it. They are truly the best in the business. This is exactly who you want taking care of your home or business.

Thank you Chris Beggs and the team for all you do for us!

We! We!
