Tips From a Pro

Know your system to stay informed and in control.

  1. When it fails, shut it down.

    If your system isn't working, shut it down to avoid overheating or damage to other components from improper operation.

  2. Know your filter.

    Know the size and keep a record of the most recent filter change or cleaning.

  3. Keep the paperwork.

    Save all paperwork for future repair, warranty or sale reference.

  4. Give the equipment room.
    12″Outdoor minimum
    2′Indoor clearance

    Keep the area around your equipment clear. All HVAC systems have clearance requirements. Driftless's rule of thumb is 12 inches minimum around outdoor systems and 2 feet around indoor systems for safety and servicing.

  5. Respect the schedule.

    Be confident with your professional maintenance schedule. Don't leave a crucial part of your home unchecked for years and expect it to be ready for extreme conditions.

“Exceptional service
is not extinct.”

Business card motto, as quoted by a customer in a Google review.

““EXCEPTIONAL SERVICE IS NOT EXTINCT” that is the motto on their business card. That is a totally true statement!! We live in the country by New Glarus & our A/C stopped working. Brennan came out the next day. The unit is 21 yrs old but we wanted to keep it running as long as possible, since things made today are not the same quality. He diagnosed the issue & fixed the problem. We are happy to support local & have found our new HVAC business that we will be using from now on. Also we will be spreading the word with our family/friends. In today’s crazy world it is nice to find a company that has honesty & integrity.”

“My husband and I had a furnace issue today. We called Driftless HVAC and we couldn’t have been more pleased with the service. They were here within a few hours of our call, were very knowledgeable and kind as well. The price for service was quite reasonable. They went above and beyond, noticing things we had no idea needed addressed. We are so thankful to have experts like this so close. We will be using them in the future for sure!”
