Today our goal is simple: continue to keep you comfortable in your Portland area home. When you review our service area, you’ll discover that it’s the largest one among independent, family-owned, Oregon-based heating, cooling, and electrical companies. We’ve established and maintained this broad service area thanks to hiring the right people who treat others the right way.

When you choose our team, you can expect us to be:

  • Upfront about our process

  • Ready to offer the most comprehensive, money-back guarantees in the local industry if you’re not satisfied with our work

    A-TEMP doesn’t just talk the talk. We live up to and stand behind our words and our work.

    Company History

    Our owner, Ron Friedrich, has been in the HVAC business since 1968. For over 50 years, he has installed and repaired thousands of HVAC units just like yours throughout Clackamas, Multnomah, and Washington Counties. He knew from the start what makes an HVAC company provide outstanding service and has been committed to providing it to every client throughout his career.

    Ron started A-TEMP because he believed that homeowners in the area deserved better than what was then available for their heating and cooling needs. Ron’s founding philosophy hasn’t changed. Over the years, our company strives to be better than before—better people, better services, and better results for customers.

    A-TEMP is designed around excellent customer service and we are always doing what is best for our customers’ interests.

    What You Can Expect from the A-TEMP Team

    People grow into their professional skills but come equipped with character traits that define who they are. A-TEMP is and always will be a character-first company. We define an A-TEMP employee by his or her character more than a set of skills. We look for honesty, clarity, good judgment, and a host of other traits as we consider if someone is the right fit. We believe that if a person fits our environment, we can help him or her expand into any number of roles or specialties.

    Our people have room to grow, from beginning technicians to Comfort Advisors, office personnel, and managers. This is because we focus on who they are and work with them on what they do.

    We’re confident that our advisors and staff members are excellent at their jobs while being trustworthy and respectful at all times. Or else they wouldn’t be part of A-TEMP.

    We are ready to work for you. Give our Portland heating, air conditioning, and electrical experts a call at (503) 694-3396 to get started.
