Tim and Tai did a great job installing my new HVAC system! They were thorough, respectful, and did very good work. Would highly recommend to anyone needing their services.

Liz Jimenez

I recently had new ducting installed by Tim and Tai, and I couldn’t be more pleased with the experience. From start to finish, Tim was friendly, professional, and easy to work with. He explained everything clearly, completed the job with great workmanship, and made sure everything was cleaned up at the end. Tim also brought my air unit up to code, which gave me huge peace of mind. The price was very reasonable, especially considering the high quality of the work. It’s clear that Tim takes pride in what he does, and it really shows in the final result. I highly recommend him to anyone needing ducting, code updates, or similar services — fantastic service all around!

RT Olson Plumbing, Heating and Air Conditioning team of Tim,Scott,Tai and Mason did an amazing job for our home with a new comfortable central heat pump installation with new air ducting and attic insulation! We opted in to get an air purification system and a nice pleated 5 inch thick air filtration system. We are excited to see how well they work during the demand seasons. They are skilled, very knowledgeable, organized, efficient and friendly. I recommend them highly . Thanks for our comfortable safe home. Added photos to show you all how hard they worked and how well it came out! Last photos are to show how it looked before.

Needed to update an aged heating and air system; quick service, options explained, no pressure to buy. The guys went above and beyond installing a new cost efficient system into my home, Very happy with service received, installed in a full day. Even went above and beyond to assist with an unrelated issue. Customer service of this quality is rare, highly recommend RT Olson Heating and Air. Honest, dependable guys that go out of their way to do a fantastic job.
