Why Choose The Good Guys?

We know you have several options when it comes to Heating & Cooling contractors. It is hard to compare businesses as we all go about doing business in different ways.

Family Business

Our Christensen family has been in the trades for 5 generations spanning nearly 100 years. We started Christensen & Wisnet when Earl Christensen came back from the World War II, and started working for his uncle at Schank & Christensen. When his uncle decided to just close up shop instead of passing it down, Earl went into business with Joseph Wisnet (senior). We opened our shop in 1966 offering full service of HVAC equipment as well as oil delivery. We have since sold off our Oil Division to focus exclusively on Heating & Cooling service. The business is currently operated by John Christensen and Joe Wisnet, and soon to be Andy & Dan Christensen.

Award Winning

We have won or were a top 3 finalist in the Post Crescent's Best of the Valley in 2010, 2011, 2012, 2014, 2015, 2016, 2017, 2018. We have won the Angie's List Super Service Award in 2011, 2012, 2013, 2015, 2016, and 2018. When we reach out to customers to share their feedback we are currently at a 99.5% satisfaction rate. We truly care about running our business ethically and upfront.

Ethical Sales

We DO NOT use high pressure sales or try to force anything on customers. While we may make a recommendation, they are merely a recommendation. It is ALWAYS up to you what you want to do. Our estimators are both very knowledgeable and friendly. They want to earn your business the right way!

We Make it Right

We are first to admit to you that we are human, and sometimes we make a mistake. We do not try to get away or distance ourselves from it, we embrase it. We solve it, and make sure we do right on our customers. Of course we need to throw it out there that the mistakes are few and far between, but they do happen time to time. We back our installed equipment with a one year 100% satisfaction guarantee, that if you are not happy with it, we will remove it and give you 100% of your money back.

Customer Focused

You will find our customer service is second to none on the phone. During regular business hours we answer the phone directly. We respond to emails or online requests fast. Our goal is to impress you at every turn of our business. Our specials are fair to everyone, and we run specials for existing customers (not visible to the public) as we believe in rewarding loyalty.


We have worked hard in the past decade modernizing our business. Our customers enjoy the conveniences like: Online Bill Payment (2009), Online Account Access (2012), Self-Service Estimate Sheduling (2013), Self-Service Tune-Up Scheduling (2016), Online Troubleshooting and Help Center (2017), Live Service Call Status (2017)
