"Four Winds is a highly professional locally owned business. From scheduling through the completion of the installation process, my experience has been very positive. Four Winds has installed furnace and air conditioning systems in my home within the past 18 months, after years of their excellent service of my old HVAC system. Staff are respectful, customer oriented, and highly trained to do the job expertly. The company is ethical and great to work with. I recommend Four Winds wholeheartedly!"

"This is hard to believe but the HVAC guy that installed the GeoThermal refused to repair it because it was 4 years old. I found Geothermal Specialist through HomeAdvisor, these people got on the repair in less than 24 hours after my call, but also showed me that the Modine Geothermal has a 10 year parts and labor warranty."

"It has been a long time ago. They were good. My only problem was in an emergency, they did not return my call and I called someone else. I was very pleased with the new one which was Rohdy's Heating and cooling in Dowagiac. I have used them ever since. I apologize for not being more accurate, but it has been a long time ago."

Thank you for helping me find them, Home Advisor/Angi!"

"The representative who has been taking care of me here is James. He is on top of the line. The thoroughness and efficieny which James have performed not only with my heating but also my air conditioning are probably the reasons why I'm staying with them. I'm confident I know what he's gonna do. I know I don't have to watch over him because he will do a good job. He has been in the industry and he knows. I feel very confident. I would give him A all the way round."

Heating and Air Conditioning questions, answered by experts

For the most part, you should leave your AC fan in “auto” mode so that it only runs during a heating or cooling cycle. Keeping it in this position uses less energy, which equals lower utility bills. However, there are some situations where it’s better to leave your AC fan on, including if you have allergies or there are lots of people in your home.

To extend your HVAC system’s lifespan, it’s crucial to keep up with maintenance. This includes changing filters and thermostat batteries, keeping the outside unit clean and clear of clutter, and lubricating moving parts. Watch out for leaks, mold buildup, and blockages to ensure your unit stays in good working order. Spotting these issues early can be the difference between a simple, wallet-friendly repair and an expensive replacement.

You should know the main components of an air conditioner: the condenser coils, evaporator coils, drip pan, AC filter, ducts, and refrigerant. Each part plays a key role in the performance and safety of your AC system. When tracking the source of AC issues or odors, it helps to know where to look. Your outdoor unit houses your condenser coils, fan, and compressor. Your indoor unit houses your evaporator coils, drain lines, and filter, and it connects to your ductwork. 

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.

If you have central air conditioning, it’s fine to run your AC all day if that’s what you want—as long as the AC unit is in good condition. But if your AC runs constantly when you don’t want it to, there may be a problem with your system (like the ones we’ve mentioned above). Window AC units and wall air conditioners aren’t as powerful as central AC, so you should only run those kinds of air conditioners for eight to 12 hours at a time.
