The Benefits of Experience and Longevity

Carlson Heating & Air Conditioning opened its doors in 1961 and we’ve been providing comfort to the families of Kelso and Longview ever since.
After-hours furnace repair in the middle of the winter? Air conditioner needs service in the sweltering summer heat?
No problem. For 60 years Carlson’s Heating & Air Conditioning has been there when the fine folks of Cowlitz, Columbia or Wahkiakum County have called.
Now with the fourth generation of the Carlson family working in our offices, we’re still doing the same thing since Vern Carlson opened the doors for the first time in 1961 – providing stellar furnace repair and air-conditioning service to Kelso and Longview, WA homes and businesses.
Our NATE-Certified technicians are trained on the latest and most advanced equipment. Our installation team employs state-of-the-art software to quickly and accurately determine the optimal equipment for your unique comfort situation.
More importantly – when you call our office, you’ll talk to a real live person every time.
While we make sure we’re up-to-date on the things that matter, we’re decidedly old-school on the other things that matter. Like performing quality work for a fair price on each and every job we do.
Call Carlson’s Heating & Air Conditioning and discover the benefits that come with experience and longevity.

Satisfied customers are part and parcel of the work we do...

After doing my homework, I chose Carlson's to provide and install a Daikin heat pump and air handler. I am so glad I did.... everything is working great.
I highly recommend Carlson's for their professionalism, promptness, and attention to detail.

Incredibly professional and always respectful. Rates are competitive and the staff is fantastic. What else could you ask for?

Cory B.

Called Carlson's and they sent a tech out within a couple hours who was friendly, professional and found the problem right away. Got us back up and running within 30 minutes.
I will be calling the next time we need service and/or maintenance.
Thank you!
