We are an American standard customer care dealer which means we go above & beyond to ensure a great experience with Clark heating. We have many times been recognized as "dealer of the year" for providing unmatched service. We've accomplished this by maintaining customer satisfaction rating of over 98%. Contact us today, we'd love to make you a satisfied customer too.

"Great to work with. They were efficient and knowledgeable. They took care of the rebate for our heat pump. Only thing lacking was responsiveness to email/phone communication after the install was done. Heat pump system is working great."

Since 1984, Cardinal Heating, Cooling, Plumbing & Electric has provided the Sun Prairie, WI and the surrounding area with exceptional Heating, Air Conditioning, Electrical and Plumbing services. We offer professional technicians, same-day installations and 24-hour emergency service. We believe we are the right choice for any of your HVAC, Plumbing, or Electrical needs. Call today to schedule your next appointment!

"Had an old fixture above kitchen sink go kaput (fluorescent starter disintegrated), so Cardinal came out and offered LED alternatives (two provided, brought on-hand from supply warehouse). Also fixed a switched outlet that had shorted out. Great work done, nice alternatives for the LED light, and switched outlet was wired to be always-on for one socket and switched for the other -- better than it was before at no additional cost. Later I called to ask the exact serial and model number of the LED light because the papers left did not state it. Not only did I get an email a couple hours later with the model/serial, the tech included the detailed documentation for the fixture so if anything goes wrong I can likely fix it myself next time. The tech who did the work also applied a 10% off discount card for me with no extra hassle, saving me close to $100 on the work."

"Multiple exterior repairs including: enhance the structure of a 2nd story porch, repair wood rot in several locations, storm door replacement, fence and post replacement and painting. Adam treats your house as if it's his own - he discovered additional wood rot and mouse entry points on the siding and re-fastened framing on the front door so it now operates like new. My house is now mouse free for the first time since it was purchased 28 years ago. Adam comes up with great solutions that I've never considered. There's no need to check his work with a level - it's always right on. He always does things the right way and gives you options to suit your budget. I'm a probably a difficult customer since I'm a retired engineer and Adam meets or exceeds all expections."

Heating and Air Conditioning questions, answered by experts

Zoned HVAC systems can be worth it for some homeowners, even with the added HVAC replacement costs, because they offer tremendous benefits. Zoned HVAC may offer greater stability and efficiency if your home has multiple levels and experiences constant temperature fluctuations. However, even smaller homes without major fluctuations can benefit since zoned HVAC systems can adjust their temperature more quickly by heating and cooling only the spaces you need.

Yes, having mismatched evaporator and condenser coils in your AC system can lead to serious issues. For instance, it can result in higher monthly energy costs as the system runs longer to compensate for the mismatch. This mismatch can also put extra stress on the system, compromising its efficiency and longevity. 

Along with that, mismatched coils can lead to higher temperatures and humidity levels in the home. What’s more, using coils of different sizes may violate the manufacturer's warranty, as they are designed to work synergistically, and any mismatch could lead to repairs and system failure.

Set your house temperature between 55 and 85 degrees Fahrenheit while on vacation, depending on the season. If it’s winter, don’t go below 55 degrees. In the summer, the best AC temperature for energy savings is no higher than 85 degrees. You can save anywhere from 10% to 15% on your energy costs by adjusting the temperature while you’re away. If you have a smart thermostat, set up vacation modes for each season. On your way home, turn off vacation mode to allow the home to warm up or cool down before you arrive.

A 10,000-watt generator can run a small to mid-sized central AC unit (typically up to 3 tons or 36,000 BTU) along with a few other appliances. However, larger AC units or additional loads will require a bigger generator. Consult a local generator installer to ensure you add the correct size generator to your home.

Signs that your air conditioner capacitor is malfunctioning include a smell or smoke coming from the unit, a humming or banging noise when it starts, the system shutting off randomly, higher energy bills, and no cold air blowing out of the unit. Additionally, if your capacitor is bad, the air conditioner may not turn on at all.
