subject: How To Spot The Best Central Air Conditioning Systems [print this page] To identify the best central air-con systems, you have got to do more than depend on the word of the vendor. A cooling and heating company is like every other company : it's in business to earn income and will present you with the best case scenario for all of its products, even if some of those products represent a "good" choice and not the absolute best choice for your present position.
Generally, the best central aircon systems are the ones that operate on nominal electricity to keep your electrical bills as low, offer reliable performance for their projected lifespan when correctly maintained, operate silently and need minimum servicing all though their life-span.
To evaluate particular air conditioning systems by these criteria, researching professional and customer reviews is an excellent resource. But before you decide to buy an air-conditioner, you'll need to answer two questions concerning your particular needs and wants.
While an air conditioner that is too tiny will not be well placed to keep your house as cool as it should be, purchasing an air conditioner that is too giant will turn off and on more often without providing a raised level of cooling. As well as adding up to wasted money in term of clobber cost, a system that is too giant can also saddle you with seriously higher electrical bills alongside lower the lifespan of the air conditioner thanks to the additional strain that results form its turning off and on so often.
To pinpoint the right size air-conditioner for your house, it's most sensible to have an HVAC technician conduct an intensive study of your cooling needs, which will rely upon factors such as window dimensions and exposure, sq footage, your house's landscape alignment, the presence of direct shade, local climate and insulation. When the technician finishes his inquiry, he'll identify what size air-conditioner you want re Btu / h or tons. Btu / h stands for Brit thermal units of heat removed per hour and one ton is the same as twelve thousand Btu / h.
Air conditioner manufacturers are required by law to rate their air conditioning equipment in terms of energy efficiency, which is known as a Seasonal Energy Efficiency Rating (SEER). The higher an air conditioner's SEER rating the greater its energy efficiency. In most cases, new homes are built according to a standard builder's model.
But when it is time to replace your air conditioner, moving to an energy saving model is always an additional benefit. Energy conservation aircon is a choice for each home, and while air conditioners with the highest SEER ratings can cost more than lower rated air conditioners up front, they usually more than make up for your original investment by giving you seriously reduced electrical bills over the course of their lifespan.
