Secondly, it helps maintain air quality of air indoors.

Energy efficient cooling system rated with SEER 9 and above is popular in the US. By converting to SEER 13 from 9, one can reduce power consumption almost by 30 percent. This is a great thing as almost $300 can be saved every year.

Energy efficient heating systems like zoned heating, water heating and geothermal heating have become popular. Modern technology has made it possible to save energy.

Besides, some companies have also invented technology to enhance the efficiency of the already existing HVAC system. Replacing the existing one can be expensive, so you can install these.
