Real customers. Real results.
"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."
"Nathan cleaned out our central heating and cooling vent system in our house when we lived in Nevada drive in Longview WA. Not only did he clean it out, but he also did some repairs and re-supported the duct without being asked to. You can tell he works with integrity, going above and beyond on the job."
"Nathan is fantastic! He gave my husband all the info he needed over the phone! If we ever need HVAC service his will be the only number we call!"
"Nathen is a great technician, he's very knowledgeable and went above and beyond repairing my 20 year old a/c system, he was quick to diagnose the problem, replacing the burnt out compressor motor and worn out capacitors, charged the system to spec and then my fan motor wouldn't kick on, so he drove 2 hours to get the right one and had me running ice cold the same day!"
"Nate was great. He is reasonably priced, his customer service is easily one of the best I have seen in my 50+ years here on the earth. He is extremely detailed oriented, explains everything clearly and is very friendly. He only installs top of the line product that will help me save on my electrical bill, both during summer & winter. I would recommend Nate and his services 100%."
