What is a Heat Pump?

An air source heat pump (ASHP) is an electric heating and cooling system that can condition homes more efficiently than traditional heating and cooling systems. Rather than generating heat as a furnace would, heat pumps simply move heat from one location to another.

While heating your home, heat pumps extract heat energy from outdoor air and transfers it inside. When cooling, the technology works similarly to your air conditioner and removes heat energy from inside your home, expelling it outside.

Dual Fuel Heat Pump Systems

A dual fuel heat pump system consists of two main units: a heat pump and a natural gas or propane furnace. The heat pump operates as the primary heating and cooling source, utilizing electricity to transfer heat between the indoors and outdoors.

However, in situations where the outdoor temperature drops below zero, the heat pump’s efficiency may decline. That’s where the backup furnace comes in. When the weather gets too cold for the heat pump to efficiently heat your home, the backup furnace automatically takes over and provides additional heat using natural gas or propane.

The heat pump is more energy-efficient and cost-effective to operate during milder weather, while the backup furnace provides more energy and cost savings during extreme cold snaps.

Heat Pump Frequently Asked Questions

Are heat pumps suitable for Wisconsin’s cold winters?
Absolutely! This is especially true if you opt for a cold climate heat pump which is specifically designed to operate in sub-freezing temperatures. Another option would be to consider a dual fuel heat pump system.

Do heat pumps require regular maintenance?
Like any HVAC system, heat pumps require regular maintenance to ensure optimal performance, efficiency, and longevity. Routine maintenance also keeps your manufacturer warranty in good standing.

Can I get a heat pump system if my home doesn’t have ductwork?
Yes. Even if your home doesn’t have any existing ductwork, there are heat pump options available. These systems are known as ductless mini-split heat pumps.

Been in our home almost 35 years. Couple months ago, I saw water on the floor under our washing machine. Decided to replace the washer. Went to the basement to look above where the laundry room water supply lines come up through the floor and saw an electrical junction box under the supply lines. Checking the box, there were mineral deposits on the cover, suggesting water leak in the past. Figuring electricity and water don't mix too well, I called KM Heating & A/C's electrical division to have someone come out to move the junction box, as our sump pump is plugged into a socket on the junction box. Josh was out on April 19 to do the repair. He chose to move the box over a foot away from the water supply line and managed to get the job done quickly and efficiently. Wiring was added and new conduit with connectors were put in. Couldn't be happier to know the new junction box won't get wet, spark up, or cause a fire. New box and conduit can be seen in the picture.

We had a great experience having Kettle Moraine install a mini split heat pump on our sunroom so we can use it year-round. Scheduling the estimate was really easy, Jay was very patient with us as we asked a lot of questions about the different options we could use for the room, and then Sherri in the office was awesome for figuring out our final details and payments. The crew on the install day was on time, didn’t leave any trace that they were even here, and did a great job. The pricing was comparable with the other big companies in the area but we felt most comfortable with the staff at KM.

I called Kettle Moraine Heating & Cooling llc to have an AC unit that had been out of service inspected and returned to operation. The AC unit had not been in use for a few years and had a potential unknown leak. Luke contacted me and arranged an arrival time and he arrived at the stated time. He was very thorough in his inspection of my complete system. Luke determined it was likely that a previous contractor had put leak stop into my systems coil. Luke informed me that although it was not KMHC’s practice to do this he said it seemed likely that it may have worked to fix the leak however was clear that although he had charged the AC system with pressure to test for leaks that it was possible that the system still had some leak somewhere that could reappear. He told me the options of either taking a bit of a risk and charging the system or replacement. He was clear that charging the system offered no guarantee but that there was a potential to save quiet a bit of money if it did work. We chose this option and are moving forward with some confidence that we are hopefully making the right choice although there is a risk. Upon inspecting our complete system Luke determined that our Furnace blower was not working properly and thankfully it was indeed still under warranty which in the end will save me $1800 dollars on replacement. Luke ordered a replacement blower and he will call me and return to install it . I am very confident in the work and inspection that was done and will always return to Kettle Moraine Heating and cooling in the future.

Mark Billeb was on time and very cordial. He completed the annual service in a very timely manner. He was also able to repair the low voltage wire leading back to the A/C unit. I told him that if the weather wasn't good not to worry about repaing the wire. He had it completed before the rain hit. I appreciate the hard work that he put in to make sure that it would be completed.Thank you for a job well done!!!!!!

The installation crew were right on time and did a professional job. They were all all professionally dressed and very respecful and great guys. They installed my new modulating furnace, modulating air conditioner, new thermostat, and a new Merv 16 filtering. They installed it all within about 6 hours so don't worry that you will be without air or heat until the next day. They cleaned and vacuumed around and it was cleaner than when they started.I was amazed when they started it up. I asked is it on and he showed me it was running and I had to go to a vent and feel if the heat and later the cooling to verify it was running. Its so quite that we can watch TV without turning the volume up when the furnace comes on.I suggest anyone in the area get a quote from them and thy will be competitive and do a great job.

I contacted Kettle Moraine Heating and Air to check our furnace and determine why it wasn’t running correctly. They said they could have a service tech at my house at 2:00pm. Brett arrived at my house promptly at 2:00 and began working to determine what the problem was. He figured out that the problem was the blower module, but unfortunately he didn’t have the part on his truck. Brett didn’t want to leave me with a inoperable furnace and schedule another service call, so he drove back to his shop to get the part and quickly returned to my house in less than 30 minutes.The new part was installed and the furnace was up and running in no time.Brett is a very professional and knowledgeable technician, and very friendly and easy to talk to. He explains how furnaces work and describes what needs to be done to maintain them correctly. Brett is a great asset to Kettle Moraine Heating and Air, and to his customers!

My wife has worked for Costco for 13 years. When we received a quote for replacing our HVAC system, I joking asked," Does Costco have discount for HVAC?" That is how we got in touch with Kettle Moraine. We had a little more than 2 weeks to get this done to qualify for federal and state incentives. Jay Zeman made this the easiest decision to make! He worked with us and responded promptly. He saved us money by investigating and applying every possible discount and rebate. Comparison with competitors pointed everything to Kettle Moraine. Another factor was that any time I had called, a pleasant knowledgeable person answered every question and concern I had! Thanks again to Jay and crew. And to know that they are a complete home repair operation insures that they will be hearing from me when needed!
