Choosing the Right Size A/C

Choosing the Right Size A/C

Sometimes people conscientious about saving money purchase an air conditioning unit or system too small for their needs.  Unfortunately, underestimating cooling needs may cost you some sweat as well as some extra money.

At the other end of the spectrum is the fact that buying more power than you need can actually cause the living space you are trying to cool to become cold and clammy.  Please make sure that whoever you hire as your contractor calculates the size of the cooling equipment you need by using a recognized method such as the Air Conditioning Contractors of America (ACCA) Manual J.

If you have ductwork in your home for your heating, adding a central system may cost you less; however, be aware that not all ducts used for heating are not be the right size or in the right location for optimal cooling. In making a proper determination in this matter, your contractor should use a duct-sizing method such as the ACCA Manual D.

Professionals make sure that all duct sections are of the proper size; and, they assure that there are enough supply registers to sufficiently deliver air to the right spots. Proper ductwork size is absolutely essential for meeting each room’s cooling needs as well as to avoid the noisy operation that can result from undersized ductwork.

Leaky or non-insulated ducts can considerably reduce system efficiency.  HVAC professionals doing a thorough job make sure that all joints and seams are sealed (we don’t mean with duct tape!).

Adding ducts, changing ducts, central air, and a split-ductless system are just some of the choices you have when you look at a new installation, a replacement or an upgrade.  Electrical connections, possible refrigerant and condensate drain locations, whether or not a design is conducive to installing ductwork, the size of the living quarters and exactly what is that you hope to accomplish are all considerations an HVAC needs to take into consideration as part of a thorough conversation with you.

Having the proper size A/C unit or system to provide sufficient cooling capacity is very important to your comfort as well as your long-term cost.  Long-term costs are also among the reasons for a 5-2-1 Compressor Saver® should be considered in many circumstances.

Now, newer top-of-the-line air conditioners often come from the factory with 5-2-1 technology built in. If yours isn’t one of those, don’t be pushed into buying a new unit or system due to this feature if it is not warranted.  A trained, knowledgeable and honest HVAC professional can determine if a 5-2-1 Compressor Saver® is a wise adjunct to your existing air conditioning unit or system.

The 5-2-1 compressor saver does just what the name claims.  In addition to cutting the starting time by 30%-50%, this product is reliable and draws less power (as evidenced by no more dimming of your lights on startup) and saves you money on your electric bills.

The cost of a 5-2-1 Compressor Saver® is a fraction of the cost of replacing an AC compressor damaged by hard starts. It could also add years to the life of your compressor and other electrical components associated with your AC system.
