Everyone is familiar with central air conditioning systems. These systems will make use of ducts to efficiently disperse cooled air over an entire building. These are designed to be what we refer to as "split systems" as they are designed to have the condenser with compressor outdoors and fan and coil indoors. Refrigerant will be circulated between these components of the system via piping. The way these systems operate is that the refrigerant cools the air while a blower then pushes it through the ducts - as simple as that, your home gets cooled.

But what is not so simple is determining the proper size unit for your house. If you get this wrong, it can be very expensive to rectify, or you end up with a system you are never really happy with. So, size does matter! If you install a unit that cannot supply as much cooling as your home needs, you very well might end up sweating a lot more than you would like. On the other hand, install a unit more powerful than your home space requires and your home could very well end up cold and quite possibly clammy.

Any professional AC contractor, like TCS, will be able to calculate the size of the equipment your house needs using recognized industry methods. For those homeowners that are fortunate enough to already have ducts running through their homes, adding or replacing a central system will likely cost less than those that do not them them already. The thing that homeowners need to understand is that in some cases the ducts used for heating may not be a good fit for cooling due to their size and/or location.

That's why a professional contractor will use industry standard methods for determining the optimal size for your ducts. Professionals will ensure that all sections are sized optimally and that there are plenty of supply registers to deliver the right amounts of cooling to the right spots in your home - this is essential for meeting the cooling requirements of each individual room.

For homes that do not have existing ducts, they can be somewhat costly to add, but for homeowners that want to cool an entire home, central systems are typically the best choice.

Now for homeowners that are considering an upgrade, you really do need the assistance of a professional. You can't just assume that if you purchase the same size system that you had before that you will be getting the exact same performance from the unit. For example, and changes to your building's structure or any improvements made for energy efficiency, such as replacing windows or adding insulation, can affect you cooling equipment requirements. Add to this the fact that today's systems are 20 to 40 percent more efficient than minimum-efficiency models made even 10 years ago and replacing and upgrading are not as simple as it may seem. A professional contractor will perform the same sizing analysis for equipment involved as for installing a new system.
