What is Geothermal?

How Geothermal Works

No matter what climate you live in, the temperature throughout the year varies. For some climates, temperatures will swing from blazing Summers to frigid Winters. What many people don't realize is that the temperature below ground, regardless of climate or season, stays fairly consistent all year-round.

Quality First. Quality Always.

“I used Bill Wenzel for geothermal systems in 2 homes I built in the last 5 years. Having to deal with contractors is usually a difficult process, but Bill and his team were consummate professionals who went above and beyond all expectations. When I asked him why he is different than other HVAC companies, he stated, “It’s my name on the system.” It’s that simple: Bill cares about his reputation and only wants the best for his customers. His workmen are friendly and knowledgeable; it is obvious they all enjoy their jobs.

I do my homework when I chose a contractor and there are other geothermal companies who may be less expensive, but they utilize products with less quality. Well, quality matters to me when one must spend a lot of money on a HVAC system. When you want the best and someone who stands behind their work – choose Bill Wenzel.”

“I just want to say how pleased my wife and I are with the results of the geothermal install. The system is a huge improvement over the previous propane furnaces. We now have better air quality, less noise, lower operating cost and free air conditioning. Thanks again for your expertise and quality workmanship.”
