"My wife and I moved to Red Wing in 2021. We purchased a home that had a newer furnace that was installed by John with Ziemer Heating and Cooling. I have reached out to john twice since we have owned our home. The first time was to look at out AC unit to make sure it was running right. He made sure everything was operating properly, cleaned it and also gave me some maintenance tips! The second time we contacted him was for a furnace tuneup. He was able to get it done within a few days! He double checked everything and cleaned up the burners. Overall, we are really happy with our experiences with Ziemer Heating and Cooling. He is very prompt, polite and knowledgeable. We don't plan on going through anyone else!!!"
