Report
Our A/C went out on Sunday, and I called the first local HVAC company that popped up via Google. So glad I did. I called 1st thing Monday morning and had a technician here Monday afternoon. Nathan was quick to find the problem and honest with the solution. We were up and running Tuesday around noon, so only a couple of days of hot in the house. Everything has been running great, and I do highly recommend Johnson Heating and Cooling for your HVAC needs. Affordable and reliable.

They were so nice and scheduled us in very quickly when we called because our AC wasn't keeping up. Very professional when he came for the appointment and explained everything and didn't mind my pups running about :) Will definitely use in the future and wouldn't hesitate to recommend!

I'm in the process of finishing my basement and HVAC was the one part I didn't want to do myself. I got numerous quotes from other companies and Johnson was very fair. Their quote came in at less than half of most of the other companies. Shaun was super friendly and responsive and they came out within a few days and did a great job. Highly recommend!
