About Us

Christensen & Wisnet (The Good Guys) are a proud family business with our family's history spanning 5 generations in Heating & Cooling. Christensen & Wisnet was started in 1966 by Earl Christensen and Joe Wisnet Sr.

Back in the day

Our original location was at Outagamie St in Appleton, WI. We bought out the local Cities Service Oil Company to start our business. In our early days we sold Petrolium, Batteries, Lubricants, Tires, and Home Heating Oil. Earl & John Christensen were the service technicians, tending to furnaces. We sold our petroleum division to US Oil in 2001, and focus now on HVAC only.

Our office

We are located out by Fox River Mall in Appleton, WI on the same frontage road as Dick's Sporting Goods and Best Buy. We are open 8:00am to 4:30pm Monday-Friday (excluding major holidays). We feature a showroom with the equipment that we sell. If you are looking for ideas or need help with a problem stop in and talk with one of our experts. We love to help!

Focus on Technology

Technology and running our business efficiently is very important to us. While our industry in general is not known for being "cutting edge" we know that it is something that is important, because...

  1. It allows us to get to you faster than ever in case of emergency.
  2. It gives technicians more information about your equipment and service history, helping diagnosis.
  3. It offers helpful automated features you can use whether we are open or closed.
    1. Online Bill Payment
    2. Online Customer Portal
    3. Online Estimate Scheduling
    4. Online Tune-Up Scheduling
  4. It helps us eliminate human error, so things are not forgotten or delayed.

We are proud to say that most of our day-to-day software was designed and built in-house, specifically to our unique needs.
