Central air conditioning

Usually many people have already been installed the central air conditioning units while construction their house. Therefore not-surprise if find data that shows 80 percent of the new houses in U.S install these units while building. But don’t worry, they also can be installed while construction new houses or in houses which have already been built.

There are two points that must we keep mind when we want purchase and use central air conditioning units that are about the efficiency and the installation. When we discuss about the efficiency then usually we will discuss about SEER. SEER stands of Seasonal Energy Efficiency Ratio. It is as parameter to measure how efficient of the units. So as higher value of SEER, then it indicate as better efficiency of the unit.

Central air conditioning units have to install with a qualified professional contractor, because usually they have just little bit more complicated installation procedure than other models like portable types. Therefore we have to provide the additional cost for the installation properly.

Heating and cooling are two kind activities that consume energy lot every year. Or we can also say with other statement that using central ac units is a major source of the energy consumption of every year. Discuss about the central air conditioning cost, there are many factors and points that we must analyze to determine how cost to operate central air conditioning units monthly. Because the installation is not easily or we have to pay a qualified professional contractor, the installation cost also must be considered. Below are some related issues about cost that that we must pay when we use central air conditioning:

1. The first thing that we must concern is about what type of our central air conditioner! Basically they consist in two types that are packaged types and split system types. According to EPA report, especially cost for purchase and cost for the maintenance and operation, both doesn’t have differentiates significantly. But there is one thing we must consider that is about Energy star rating. As add information Energy star is a program to certify and measure in a value standard how efficient the unit is! It is published by the United States Department of Energy and EPA (stands of Environmental Protection Agency). Star energy can help consumers to choose the units that can work in good efficiency energy usage.
2. The units that have been qualified with energy star EPA usually are more expensive than the units that don’t have certified energy star EPA. The different prize is so significantly, such as of 2009, if we buy 2.5-ton central air conditioning with certified energy star EPA we must pay up to $3,200, but we just pay only $825 or less for the same unit models. The price that we usually buy unit and also the installation call as the initial cost. Usually both to be one-package of the purchase prize. The initial cost is also influenced with the kind brand of the unit.
3. Better we prefer to use units that have certified energy star EPA! Why? Because it is so useful to minimize operational cost monthly. Usually the energy star units only need operational energy cost around $500 per year. But if we use units that non-energy star EPA we must pay additional cost up to $100 or more! It means we have to pay for energy operational cost up to $600 dollars or more per year if we use non-energy star certified. And of course, it is bad for long time usage!
4. After consider about the cost that we must pay for the energy consume or usually call as the energy bill monthly. Then don’t forget to consider about the maintenance cost. Well central air conditioning units need to maintenance every few years. There are some parts that must be checked or even be replaced with new parts such as filters, etc. Sometimes if we get the problem that we cannot handle self, then usually we call a qualified professional service to resolve. Therefore we also should concern about the labor cost.
5. As addition tip, better we always check the ducts and make ensure they always in right condition because the bad performance of the ducts will influence significantly the energy consume. It means the better quality of ducts that we use will give contribution significantly the unit can keep work in the best efficiency level performance.
