"I had been unhappy with another firm in Madison that has worked on both our furnace and central air conditioner, so I contacted Clark, based on a recommendation from Dan of Jenko's garage doors, and checking on Angie's list, where Clark was highly rated. They sent a serviceman (I think it was Kevin) last Tuesday, who inspected our system, which had been installed in 1992, and determined it was leaking Freon. He indicated that repair was not a smart option on an old system and recommended a new air conditioner. Andy came came out on Thursday to give us an estimate. I asked if he could have it installed on Friday, as it was very hot and humid and we were having guests over for dinner. He said he could make it work. On Friday his crew (Jeff and his partner) spent about 5 hours removing the old unit and installing the new one. They were completely professional and thorough. By 5:00 the house was cooling down. I highly recommend Clark Heating and Cooling."

"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.

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!"

Heating and Air Conditioning FAQs, answered by experts

No, a furnace is not the same thing as an AC, or air conditioner, but these are both parts of an HVAC system. They both use air ducts to transport cool or hot air around your home to achieve a comfortable temperature set by your thermostat. An AC runs on electricity, while a furnace can use different fuel sources.

Whether an HVAC damper should be open or closed depends on the season, the zone it controls, and the temperature in that zone. In the summer, open upstairs dampers and close lower-level dampers to get the most efficient cooling possible. In the winter, do the opposite. Cool air will naturally flow down to lower levels, while warm air will rise. This keeps your system from working harder and helps prevent common AC problems.

Assessing location for airflow, convenience, and minimal noise impact.

Traditional central air conditioning systems require ductwork to circulate air throughout the home. Alternatively, you can add air conditioning with a mini-split ductless air conditioning system, which can be just as energy efficient as a central air conditioner. This type of system consists of two units–an outside unit that holds the compressor and condenser and an indoor unit that holds an air-handler. With multi-zone ductless systems, there are multiple indoor air handlers tied to a single outdoor compressor/condenser, allowing the system to cool multiple rooms.

While it's generally safe to stay in a home with a coolant leak if your home is properly ventilated, it's important to have a professional come out to assess the situation right away. You should evacuate your home if you notice any powerful fumes. Additionally, you should leave your home if you are experiencing headaches or dizziness.
