The moment the summer weather starts to set in here in the Twin Cities, many residents immediately reach for their thermostats and start lowering them by at least a few degrees. While extensively running our HVAC systems can keep our homes cool, it can also result in a noticeable increase in our monthly energy bills. Many homeowners don’t realize that there are a number of things that can be done to reduce monthly cooling costs and to make an AC unit more effective, resulting in a more comfortable home environment for a fraction of the cost.
Not sure where to start? The team at RetroGreen Energy is here to help!
When was the last time you took a close look at your home’s building envelope? If the home was built prior to the turn of the century (and even if it wasn’t), there’s a good chance that it’s loaded with tiny cracks and gaps that are allowing air to flow in and out of your home at will. Naturally, this means your precious, conditioned air is escaping, and that warm air from outside is making its way into your living spaces.
The solution can be found in air sealing, which is the process of closing up these cracks and gaps so that airflow is no longer an issue.
Most homeowners living in and around St. Cloud, MN know just how important insulation is when it comes to keeping warm during the winter, but what about the summer months? The fact is, insulation is important year-round and not just during the winter, as it works in the same exact way to keep your home cool as it does to keep it warm. When combined with air sealing, insulation is one of the most effective home upgrades that you can consider if you’re looking to reduce your energy bills this summer.
Many people don’t realize that heating and cooling costs account for approximately 54% of the average American home’s energy consumption. By sealing the building envelope with air sealing and insulation, you can decrease these costs while also creating a cool, comfortable environment for you and your family. At RetroGreen Energy, we have the experience and knowledge it takes to help reduce cooling costs to a marked degree this summer—we’ll work to save you as much money as possible.

Chris didn't start RetroGreen Energy because he wanted to be in the insulation business. He started it because he wanted to fix homes the right way.
After earning his BPI Building Analyst certification and Minnesota Building Contractor license, Chris spent years studying how homes perform as systems. He saw firsthand that most comfort and energy problems weren't caused by old windows or outdated furnaces — they were caused by air leakage and inadequate insulation that nobody was diagnosing properly.
In 2009, he launched RetroGreen Energy with a commitment to doing things differently. Every project would start with proper diagnostics. Every recommendation would be based on data, not sales targets. And every homeowner would get the honest truth about what their home actually needed.
