Understanding What a Central Air Conditioning Is
More than 80% of the new houses being built in the U.S. are installed with central air conditioning units. Central air really makes sense. While it keeps the temperature at a desired level, it also filters and humidifies the air. The Central Air conditioning system is particularly great for people who have allergies or asthma. Luckily, central air conditioning systems can be built in pre-existing houses, too.
Before purchasing a central air conditioner, you should know the size of the air conditioner you need for your house. This will all actually depend on how small or big the room is that needs to be cooled. To know the most suitable size of air conditioning system for you, you must ask for the help of a HVAC contractor who can quickly determine which size of air conditioning unit is best suited for you. You can also use the “manual j calculation method”.
When purchasing central air conditioners, you will find that they contain different SEER ratings. SEER means Seasonal Energy Efficiency Ratio; this rating lets you know just how efficient the air conditioner is. Modern air conditioners almost certainly don’t have an SEER rating lower than 13. However, a few of the older units that are still in the market and were built in houses several years ago could have a SEER rating as low as 7.
One more thing to look for in purchasing a central air conditioning system is the “Energy Star.” Energy Star is a certification in appliances that use less energy. Certainly, they are more energy efficient compared to the units used in the past.
The outdoor installation of central air conditioning units may make a big difference. The air will not be able to move freely in and out of it if it is placed under a deck or vegetation is surrounding it. Not only that, the air conditioning units could also make noise. So do not place them in areas where you want to enjoy eating or staying outdoors, such as a deck or a patio.
If you are planning on having an older model replaced with a more modernized central air conditioning unit, you could actually save large amounts in your cooling bills. It is expected that upgrading an air conditioning system with an SEER of 11.5 to a unit with a SEER of 13 may give you around $500 of savings on electricity bills every year!
A central air conditioner is indeed a great option for the home, office or apartment building, and may be just what you are searching for when you want to stay comfortable and cool. If you own an apartment building, you will attract more tenants and have the option of charging a higher rent. With a central air conditioner, you are not going to think about or worry about damaging the windows when installing a window unit. Central air conditioning units are quiet, convenient, efficient, and wallet friendly.
