Having an air conditioning system that is too large for your home can have a number of negative consequences. While it may heat or cool your home faster, it can also lead to inconsistent temperatures and poor air quality, which can be especially problematic for those with asthma or other respiratory illnesses. When an AC unit is too big for the square footage of your home, it won't be able to provide gradual, consistent heating and cooling. This can result in hot and cold spots throughout your home. Additionally, the increased humidity produced by a large air conditioner can cause the air quality in your home to become worse.
Those with asthma or other respiratory illnesses are particularly vulnerable to this issue, as poor air quality can worsen their symptoms and make it difficult to breathe. It is essential to make sure that your AC unit is the right size for your home in order to avoid these issues. If you are unsure of what size AC unit you need, it is best to consult a professional who can help you determine the best size for your home.
