"I've been using Kettle Moraine Heating for my annual furnace and AC tune-ups for a while now, and I couldn't be happier with the service. Khamya Little was professional, thorough, and took the time to make sure everything was running perfectly. It's always a relief knowing my heating and cooling systems are in great hands. The team at Kettle Moraine consistently delivers top-notch service, they're prompt, knowledgeable, and genuinely care about doing the job right. Highly recommend them to any homeowner looking for reliable HVAC maintenance!"

Hi, my name is Kyra! I am currently a Cybersecurity student attending Fox Valley Technical College. I've finished my first year, and I was put on the Dean's List. I am very hardworking in school, but also in my living environment. I am very clean, and I clean for others around me often. As of recently, I have not been living in a constant home, unfortunately. A goal I have is to be able to afford an apartment soon, so that I can support myself! Even though I am only 20 years old, I have Arthritis, and I've had it since I was 5 years old. There are certain limitations I have, but I usually am able to find workarounds to still get the job done successfully. I look forward to meeting you!

Small jobs welcome

I’m Nick Herman, from the Green Bay area. Most of my career has been in flexo printing — running plants, training operators, and solving problems when the line is down. That same mindset is how I run Woodya Look At That Tree Service. I started it as a one-man operation because I like being on the tools and I like finishing a job clean. I do removals, storm cleanup, and large hardwoods — oaks included — using proper lowering and rigging so we’re not tearing up yards. I’m not a big crew with a fancy truck wrap. I’m the guy who shows up, assesses the tree, and takes it down safely. If that’s what you need, the number is 920-634-6352.

"I hired Joe to inspect and clean my AC system. I will have him come back this Fall to do the same for the furnace. He was completely honest and made sure I wasn't paying extra for anything I didn't need. He recommended topping off the refrigerant, but said it wasn't necessary, and was upfront about how much he charges per pound of R-22 and how much my system might need. Joe also gave me advise on what maintenance I should regularly do. The pricing was reasonable and probably the cheapest around. He is now going to be my goto HVAC serviceman. I would have no problem recommending him to family and friends."

Heating and Air Conditioning FAQs, answered by experts

AC evaporator coils should be cleaned at least once per year to keep your unit in good condition. For optimal performance, consider cleaning them twice a year—once before and once after the main cooling season. More frequent cleanings may be necessary for older systems, units with performance issues, or those in climates with high levels of humidity, dust, and dirt.

In most cases, homeowners insurance will cover an AC replacement if it was damaged due to a covered peril—such as theft, fire, or storms. So, if your air conditioner needs replacing due to regular wear and tear, your insurance company probably won’t pay for a new one. However, home warranties often cover HVAC repairs and replacements.

While many states do not have specific licensing requirements for HVAC companies, your local city or county might. It's always a good idea to check local requirements online and use a tool like Angi’s contractor license lookup to confirm that the company you’re considering is licensed. Regardless of licensing, you should always ensure the company you hire is fully insured to avoid potential lawsuits if a technician is injured on your property. Additionally, it is recommended to check if the company holds third-party certifications, such as North American Technician Excellence (NATE) certification or R-410A certification, which qualifies them to work with HVAC refrigerants.

While Freon is mostly odorless, a Freon leak will produce a faint chloroform-like smell. Some people find that Freon's odor has a subtle sweetness to it. Some telltale signs of a Freon leak beyond odor include ice crystals on your evaporator coil, bubbling sounds, and hissing noises.  

If your drain line is clogged, your AC might stop cooling, shut down, or refuse to turn on at all. Otherwise, you might see your AC leaking water, find standing water or water damage near the unit, or notice a musty smell coming out of your air conditioner or vents.
