Around 80% of new homes built in the United States are equipped with a central air conditioning unit. In addition, many homeowners are installing central a/c in older homes, or replacing their older air conditioning units. As a result, the prevalence and sales of central air conditioning systems is very high. Why is Central Air So Popular? Central air conditioning is the most efficient way to get cool air flow to multiple rooms in a home. Window-mounted units are economical when the intent is to cool a single small space or room, but when looking to cool an entire home, central air conditioning is the most feasible.  Central air is also quieter than window mounted air conditioners. Different Types to Consider When installing a central a/c system, the entire unit can be installed outside the home, or it can be a split device where the condenser and compressor are installed outdoors and the evaporator or blower is located inside on the furnace. The latter is the most economical.

With this configuration, the furnace’s blower delivers the cooled air to your rooms through the furnace’s air duct system. If a home doesn’t have ducts, a separate blower can be installed to distribute the cooled air. Proper “Sizing” is Critical When determining the size of air conditioner your home requires, remember that bigger is not always better. In fact, an air conditioner that is too big or too small can use excessive amounts of energy, run loudly and break down prematurely. Factors of your home that need to be taken into account to properly “size” your air conditioner include: Quality of insulation and air sealing Window size, number, type and direction Beware of Sizing by Rule of Thumb Sizing of your air conditioner should be done by an experienced professional.  Proper sizing requires taking several measurements in the home which are used, along with the features listed above, to determine the appropriate size needed. Beware of any contractor who uses a simple rule of thumb such as square footage to determine the size.

Choose well and you can save money, help the environment and enjoy year-round comfort.

The first thing to consider is whether you want your air conditioner to also heat your home. Although you can buy an air conditioner with the sole function to cool, these days many systems serve a dual purpose – they heat when it’s cold and cool when it’s hot. These reverse-cycle systems can be cheaper than throwing heaps of money at two separate units and can help keep your heating and cooling costs down.

Is it a small bedroom, a large open-plan living room or a whole house? The size of the area you want to heat or cool will give you an idea of the system size you need. It’s important to get this right – a system that’s too powerful will be inefficient (and costly), while a system that’s too small for your needs will be placed under a high degree of stress. If you want to cool multiple rooms, do you want to be able to set different temperatures in different spaces?

If so, you may want to consider buying a system with zoning. Next, have a think about where you are located. Do you live in a tropical, humid location up north, or are you in a cooler place down south? Conditions in your area will affect which type of system is best – for example, evaporative cooling systems are much less effective in humid weather. Do you live in a humid location up north, or in a cooler place down south?

There’s no point buying a system that only operates up to 42 degrees if the weather can be hotter than this. Once you’ve worked out the type and size of system that’s perfect for you home, ask some specific questions to narrow down your choice. How many energy-rating stars does the system boast?
