With HVAC systems, bigger doesn’t necessarily mean better for your Phenix, Alabama home. It’s easy to see why some may think that a large heating or cooling system will produce greater indoor comfort. There are those who might consider a smaller unit because it is more affordable. However, oversized and undersized systems are equally problematic. Properly sizing your HVAC equipment must be taken into consideration when making that very important purchase.
What Is HVAC Sizing?
HVAC sizing involves special calculations to determine which system would best meet your heating and cooling needs. Your HVAC contractor conducts a load calculation and takes into account factors such as the number of windows and the square footage of your home.
Oversized Systems Cause Problems with Air Circulation
Oversized systems don’t circulate indoor air properly. A unit that is larger than necessary will heat or cool your space quickly and then turn off. This short cycling, and the resulting poor circulation of air can cause the indoor air to become stale, stuffy and humid. It can also create problems with indoor air quality such as mold growth and the buildup of pollutants.
Undersized Systems Operate Under Excessive Stress
A heating or cooling unit that is too small will have high energy consumption. It will have to work harder to keep up with the demand for heated and cooled air. It will also be less effective at reducing indoor humidity. Sooner or later, an undersized system will become damaged by having to carry more than its share of the load. This eventually plays out in expensive HVAC repairs and in premature system breakdown.
Wrong-Sized Systems Lack Efficiency
Because oversized and undersized HVAC systems cannot perform efficiently, your energy costs will be higher. When systems cycle on and off continuously, or work harder to provide the right temperatures, they will be costly to operate. The bottom line with such systems is that they increase energy consumption and can shorten the life of the system.
