"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!"

"We had a furnace replaced by Shane. He was very professional about everything, was willing to do what he could to get our heat back on and gave us a good price for the work done. I definitely recommend JDC contracting for HVAC repair and replacement."

Heating and Air Conditioning FAQs, answered by experts

Yes, technicians check refrigerant levels, loop performance, and system calibration for peak efficiency.

AC capacitors have a wide lifespan, ranging from five to 20 years, with an average of about 10 years. Many capacitors will last for the entire life of the air conditioning unit, and most homeowners only need to replace one once. A capacitor should only be replaced if an HVAC professional diagnoses a problem with it. Premature failure can be caused by overheating, power surges, or short circuits. You can help extend the life of your AC capacitor by scheduling regular AC maintenance each year.

While 72 degrees is a comfortable setting for many people, it’s likely not the most efficient temperature setting for your air conditioning unit. By pushing the temperature up to 75 or 78 degrees, you stand to save money on your energy bill. That said, these temperatures may be too warm to be comfortable for some people and are definitely too warm for most people to sleep comfortably.

The cost to replace an AC evaporator coil is typically between $600 and $2,500, with an average cost around $1,300 to $1,350. The price of the coil itself can range from $550 to $1,100, depending on the brand, size, and style, with professional labor adding around $700. Replacing a condenser coil is generally less expensive, costing about $800. Because this repair involves handling refrigerants, it requires a licensed AC professional. Regular inspections, which cost between $200 and $600, can help prevent costly coil replacements.

You may be able to clean mold from your air conditioner in some cases. If the mold growth only takes up a small area, you can use either vinegar or bleach mixed with water to remove it. Larger areas of mold should be left to the professionals, though. It's also a good idea to leave mold removal to the pros if you are sensitive to mold or have asthma.
