You want your AC unit to spread fresh, cool air throughout your home, so it…
Size matters, at least for HVAC systems. Undersized HVAC systems will provide sub-par air conditioning, even while working flat out. Oversized systems aren’t ideal either. They cost more, run up unnecessary energy costs, and cause frequent compressor ‘on/off’ cycles. They can also be noisier than you’d like, and lead to conditions such as mold and poor indoor air quality. Incorrectly sized air conditioning systems are among the most common triggers for HVAC problems that we deal with here at Petrocelli Services. As such, we always recommend engaging a professional to determine the correct size of air conditioning system for your home or office.
How do you make sure your new HVAC system is correctly sized?
A commonly accepted HVAC sizing rule of thumb suggests 1 ton (or 12,000 BTU) of cooling per 500 square feet of space. However, the area of the room to be air conditioned isn’t the only factor you should consider. Equally important are the climatic conditions in your location, and the type and condition of your home insulation. An effectively sealed and insulated home can make do with 1 ton of cooling per 8,000-10,000 square feet. There are standards in place to help you arrive at a suitable HVAC size. Ask your contractor for details on their HVAC sizing process, and check that they’ve used the Air Conditioning Contractors of America Manual to make their calculations.
