"✨ Complete Clean made me a believer in Mondays—and that's saying something. ✨ When I reached out about our construction debris-filled air ducts, I hoped for competent help. What I got was a trio of legends: Jesse, Lefty, and Jose. They showed up on time (a rarity), treated our home with respect, and gave our ductwork the spa day it desperately needed. They even entertained my Monday blues and anime enthusiasm—special shoutout to Lefty for knowing that Eren was 100% right. Service-oriented? Absolutely. Priced competitively? Yep. And when our AC decided it needed a dramatic pause in the middle of summer, Jesse returned without hesitation to get it cooling again. That kind of follow-through is gold. Complete Clean doesn’t just clean ducts—they restore sanity, airflow, and a bit of faith in humanity. Grateful doesn’t even begin to cover it."

"We called JR HVAC Services to get a second opinion on our A/C unit not cooling. Brenton let me know when he was on the way to my house and also when he arrived. He was very respectful, which can be very rare nowadays, friendly, and knowledgeable. He looked at our A/C unit and found the problem and before he did anything, he went over what he found wrong with my husband and I and let us know how much it would cost before doing the work. Brenton was able to replace a part and get our unit cooling for less then $200 and the other company wanted to replace our unit and charge over $7000.00!! We are very pleased with this company and the service technician and the honesty."
