"After trying several other HVAC service companies, I have been using Kettle Moraine HVAC for many years now In the past they have always been very professional and quick to react to help out with any problem that has come up. This service call was a furnace/humidifier tuneup for what is a ‘new’ system for us due to a move. Doug was very prompt and had all items necessary for the job. I greatly appreciated his professional and that he took the time to show me what he was doing and to instruct me in what I should be looking for to prevent problems. He was also very patient in showing me what I can do to help my system to continue to run efficiently and effectively. I highly recommend Kettle Moraine HVAC."

"Justin took care to not over sell me. Only what I needed and understood. The install team were tidy, efficient, and educated me about the safety approaches when changing the humidifier filter. That filter and the furnace filter are the same that was used on my old system. They were professional and personable."

Heating and Air Conditioning questions, answered by experts

DIY is possible for basic cleaning. Professional services handle advanced maintenance like recharging the refrigerant.

The outdoor portions of air conditioners are designed to weather the rain, so you don’t need to worry about it. An awning or roof will help protect them from snow or falling debris, which can do more damage. This is true of both window AC and outdoor units for larger systems.

A 3-ton AC unit is probably too big for a home that’s 1,200 square feet. If you have a 1,200-square-foot home, you likely need a unit that’s somewhere around 1.9 and 2 tons. An AC unit that’s too large will be really inefficient and cost you a lot of extra money on your bills. 

Though it may seem redundant, you can absolutely have a central AC unit and a window AC in your home. In fact, if you place a window AC unit near your central air, it can help move the cooler air throughout your home. But doubling up on your AC methods can get pricey, so factor in cost accordingly.

Running an air conditioner with mold is not safe because it can spread harmful mold spores throughout your home. Exposure to these spores can trigger various health problems, including respiratory issues, allergies, coughing, wheezing, sneezing, itchy eyes, and a sore throat. It may also aggravate asthma in household members. Continued exposure can increase the risk of more serious illnesses like sinus infections, pneumonia, and bronchitis. If you suspect mold in your air conditioner, you should stop using the system until it has been properly cleaned to avoid health risks and further contamination.
