A dual fuel system lets a heat pump carry most of the Fox Valley heating season and hands off to a gas furnace on the coldest days. Here is how the balance point works and why both utility discounts apply.

Trustindex verifies that the original source of the review is Google. (Update) On all THREE instances of working with this company, all three guys showed an encyclopedic knowledge of AC systems in general and everything around it. These guys are the professionals among professionals and I have dealt with a lot of them. They explained everything in detail as they worked so I knew exactly what was going on and learned a lot about how my AC system works, which is helpful. The quotes they have given me come in just underneath the other companies as well, so it's no wonder they're busy.

Owner's reply
Jonathan, thank you for taking the time to leave this after three separate visits — that kind of consistency across our team means a lot to us. We really believe customers should understand what's happening with their own system, so it's great to hear our guys walked you through everything while they worked. We work hard to keep our pricing competitive without cutting corners, so it's good to know that's coming through too. Thanks for trusting us with your AC system, and we look forward to the next one!

Verified I hired this HVAC team to handle air supply and return installation while finishing my basement, and they did a fantastic job. The work quality was excellent, and I definitely got the best value for my money. They arrived on time and completed everything efficiently. There was a small payment miscommunication while I was traveling, but that was on my end for not conveying things clearly. Overall, great experience - 5 stars for professionalism, value, and workmanship. I’ll definitely hire them again for future HVAC needs!
