Home A/C Sizing | Air Conditioning Katy, TX

When planning to install a new air conditioner, homeowners often question the size they need. It is a legitimate concern considering a large number of HVAC contractors install the wrong size. Proper home A/C sizing of air conditioning in Katy, TX is essential for energy efficiency and comfort.

You should not assume you need the same size unit as the existing air conditioning in Katy, TX currently installed in your home. A unit that is larger than you need will costs more to purchase, to operate, reduces comfort, and increases the risk of mold and mildew.

These problems are due to a process called short cycling. In other words, it will come on, quickly cooling down the home and shut off. Short cycling causes the system to be unable to remove excess humidity, and even though it may be cold in the home, the humidity causes occupants to feel hotter than it actually is. The excess humidity will also promote the growth of mold and mildew, and can damage wood furnishings.

In addition, an upgrade in insulation, doors or windows, or other energy improvements, may mean the required size of your home’s air conditioning in Katy, TX is smaller.

An Undersized Unit

A qualified professional HVAC contractor will calculate all of the required factors into sizing calculations for new or replacement heating and air conditioning, ensuring the proper size for your home’s air conditioning in Katy, TX.
