"  IT went great!! Keith and his 4 men did a fantastic job as all ways. Clark Heating has been doing my HVAC work for years now. I would think of calling any other contractor. His price products and help are the best you can Buy.
This system was a tough one It was a old furnace in a Steel building attic hard area to work very close Quarters. The building consist of 3 large areas and a bathe room. They separately zoned all areas with each having their own thermostat. After just one day we can really tell how even the heating is. Actually had a day we turned on the air WOW works Great!
The unit is very Quiet.
All the ducting was new from ground up very neatly run. The Clean up each of the Two days it took the Men Cleaned up as though they weren't there.
This Is now my forth Job they converted, Impeccable job on all four. Would'nt use any one else!!
Thank you Keith, Jeremy, Alan Matt, Bella  For a job well done.

"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."

"Removal and install of two fixtures, changed a bulb and a switch. I thought it was rather expensive, and I probably could have done it myself, but it was for a tenant and didn't want anything potentially unsafe."

Heating and Air Conditioning questions, answered by experts

At a minimum, an HVAC system should be serviced once per year. However, a twice-a-year service schedule—once in the spring for the cooling system and once in the fall for the heating system—is often recommended, especially for older systems, heat pumps, or in climates with extreme temperatures. Regular service, which includes inspection, cleaning, and maintenance, ensures the system runs efficiently, helps prevent costly breakdowns during peak seasons, and can extend the unit's lifespan. You can also schedule a service if you notice issues like poor performance or strange noises.

If your AC unit isn’t cooling and you haven’t figured out why, there are a few good reasons to turn it off ASAP. The source of the issue, whether that be leaking refrigerant or a broken compressor, will worsen and cause more damage to the overall unit the longer the machine is allowed to run. When in doubt, shut it down until you or an AC pro can ensure everything is working properly.

Window AC units use a fair amount of electricity, but significantly less than central AC systems. Because they are more energy-efficient for cooling individual rooms or small spaces, their usage is comparatively low. On average, a window AC unit consumes between 500 and 1,400 watts, while a central AC system uses over 3,500 watts—meaning a window unit uses about one-third of the energy. This typically translates to a monthly running cost of $15 to $40, although this can vary depending on external factors.

Dry mode positively impacts indoor air quality by reducing excess moisture, which stops the growth of mold and mildew. By maintaining optimal humidity levels, dry mode creates a less hospitable environment for allergens and airborne pathogens, improving overall air quality. However, it's essential to ensure proper ventilation to prevent stale air accumulation.

Replacing both an AC and a furnace takes a full day on average, ranging from eight to 12 hours. The process involves removing the old units, installing the new ones, and ensuring all connections are properly made. If both systems are being replaced simultaneously, it can take longer than installing a furnace alone, so plan accordingly.
