Welcome to the club millions of Americans are unfortunately members of. Heating and cooling space within a home are some of of the largest energy expenses any homeowner deals with. In fact, the US Department of Energy says 42% of your monthly utility bill is for heating your home.

While there are a few common-sense tips you can follow to lower that bill (cleaning or replacing filters on a regular basis, turning off appliances when not in use or opening/shutting shades on the south-facing windows in your home), there’s actually a much easier way to save money in the long run.

Installing a high-efficiency Bosch or Samsung system can drastically lower your monthly utility bill. Both use something called a variable speed inverter-driven compressor. The variable speed controls allow the compressor to operate at precisely the speed needed to generate the cooling and heating your home needs—nothing more, nothing less. This leads to increased efficiency, which will lower your monthly bills.

If you’re interested in certified efficiency, ask your local HVAC company about the ENERGY STAR® program. Any HVAC unit that has the ENERGY STAR label has been certified by the US government to deliver quality, performance and savings.
