In modern households, HVAC (Heating Ventilation and Air Conditioning) units are one of the biggest consumers of the energy for every year. This statement is undeniable and equivalent to the fact that the average data of using energy for HVAC can reach at around fifty percent of the total energy bill or even more. It is dilemma, one side the heating and cooling are regular activity that cannot be avoided, and on the other hand HVAC system can consume high energy that not only will result problem for the finance but also can harm the environment. Along with the awareness of using eco-friendly technology and the high price of fuel, the efficiency is so crucial issue that usually many people consider at this time.

Talking and discussing about the energy efficiency of HVAC are closely related on how to reduce the energy bill. There are some choices or steps to push down your high energy bill. Well, so far by choosing to use the energy efficient system is one of the most popular choices to keep the utility bill low! There are available two popular ratings to measure the efficiency performance of HVAC units; the higher value of SEER and the Energy Star license approval from EPA. 13.0 is the minimum recommendation value of SEER at this day. Although units that come with the Energy Star rated and higher value of SEER are relatively more expensive in price but like the old saying goes, ‘you get what you pay’. It means they are smart investment to save your money on friendlier energy cost with their better efficiency performance.

The solar air conditioning and heating system is one of smart alternative solutions that have the unlimited green energy resource. That’s right; it is eco-friendly technology that uses solar or sun-light energy as the power supply. Solar HVAC is powerful enough to cool the house in the summer season, because we know well during this period the energy of sunlight can be explored more optimal and can be found easily all day long. With the free unlimited sunlight energy, the high cost installation will be returned into your pocket less than 5 years. There are also available some models that come with solar water heater appliances. These models are claimed powerful to provide up to eighty percent of home’s hot water requirement or even more in the summer.

Geothermal heating and cooling systems are the other alternative solution if you want to install and use a system with eco-friendly technology. They promise the great efficiency performance, long time durability (can survive more than 20 years) and built in with friendly environment technology. They are also familiar called as modern ground source heat pumps. Their working principle is based to the thermodynamic theory and the relatively constant temperature of the earth that usually will provide lower temperature in the summer and higher temperature in the winter. And usually consist of three major parts; ground loop design, heat pump system and the distribution units.

The last, generally the energy efficiency of HVAC system is usually influenced by some crucial factors; the local weather (geographical factor), SEER (seasonal energy efficiency ratio) of the HVAC system, the installation of air sealing, and the efficiency performance of the ductwork! Consider also some general sites that can lead to air leakage, such as; windows & doors, light fixtures, exhaust fans, vents, and to encourage the better efficiency performance of your unit!
