When buying a new AC unit, you need to remember three major things. Never purchase a unit that is over-sized, choose one that is efficient and make sure that it is properly installed.
Data revealed that a third, to at least half, oh home AC units don’t work properly because their size is not the right fit to the space they are required to operate in.
Some contractors sell AC units by at least a half ton than what the customer actually needs. Others even oversize it by more than a ton. When I say “ton” it has no reference what so ever to weight, but rather to the capacity of cooling a unit is capable of.
Once you get an over-sized AC unit, it turns on and off more frequently than required, especially during super hot days. Another thing is that you are actually overpaying for what you really need, thus you having to pay more for its power consumption.
In this case, big doesn’t equate to better, or “cooler”. Keep in mind that effectively cooling a space is about getting the right AC unit size that is proportionate to the area it needs to cool.
So to get the most out of your purchase, you need to make sure that the contractor you hired gives you the exact AC unit site. And don’t trust on experience alone and estimates. Ask your contractor to use the sizing manual used by the Air Conditioning Contractors of America (ACCA). Manuals S and J pertain to helping contractors ascertain the exact unit and size of a unit, while manual D provides information on how to design the correct ducting system for your home.
The contractor will use this manual to accurately measure the floor space of your home, note windows and how much sunlight they bring to each space, the angle at which your house faces the sun and how much sunlight it gets, as well as check the current, and needed insulation. All these data will then be entered into a formula which in turn calculates the exact amount of cooling your home needs.
Another thing to consider when getting a new AC unit is its capability of removing moisture from the air. Each model and brand has different ways on how it handles moisture. The task of your contractor would be to pick the type of unit that not only suits your home but also that of the climate your area has.
