Real customers. Real results.
"Nathen is everything you want in a contractor. Knowledgeable, courteous, neat, ethical, and a perfectionist! He spent four days at our home installing a new system. He was available to answer questions throughout the entire process and took his time to make sure we were happy with the results. There was a hiccup with our original plans but we were in good hands as Nathen is a “problem solver”. We are very happy with the work Nathen did for us and highly recommend him."

"Excellent experience with Consistent Climate Heating and Cooling LLC. Nathen was one of the most attentive, kind, and professional HVAC installers I’ve dealt with. From start to finish, he was extremely detailed, meticulous, and made sure everything was done the right way. What stood out the most was how much he cares about the little details and making sure everything looks clean and professionally done. It’s clear he takes pride in his work and truly wants the customer to feel confident in the system and the installation. One of the best experiences I’ve had with a contractor. I highly recommend Nate and I would definitely use them again in the future."
"Consistent Climate installed our complete Bosch HVAC system in 2 days: an air handler, heat coils, smart thermostat, and a beautiful vertical mount heat pump! The owner, Nathen, is knowledgeable and passionate about what he does. He is dedicated to his craft and meticulous with the details! The warranty and price can't be beat!"
