central air conditioning-what to look for?

Central air conditioning within a residence is extremely important if one lives in a climate where the summers are hot. The person shopping for central air conditioning units should look for several things to make the best selection for their household.The energy rating is an important consideration for any individual considering a central air conditioner. The central air condition systems typically advertise the rating of units available openly to help the consumers. Experts suggest that the top 25 percent of the current models available have an Energy Star rating. Air conditioning units that qualify for the rating must meet one of two criteria. If the unit is a split system, the rating must be 11.5. If the unit is a single=package model, the rating must be at least 11.0. The better the energy rating is the better potential savings for a household.The next consideration is the noise level. The unit is usually installed close to the home and the unit can be disruptive because of where it is typically placed. The noise from the unit comes from the condensing unit that is placed just outside of the home. When in the process of searching for a unit, make sure to evaluate the sound levels from the various models available. The sound levels are measured in units called bels. The scale ranges from 0 to 13. The air conditioners that have a lower bel rating are the units that run quietly.There are some other things to consider when look for a central air unit for the home. It is recommended that one look for a variable speed air handler. A filter check light can also be helpful to remind the user to change the filters periodically. The automatic-delay fan switch is another feature consumers should look for. The switch for the automatic-delay fan can cause the compressor to shut down at the same time the compressor is shut off.�
