When your Shippensburg, PA, home needs a new air conditioning system, it’s important to know the cooling load of your home. Failure of the HVAC technician to calculate your home’s cooling load could result in improper AC sizing. Installing the wrong size air conditioning system leads to a variety of cost and comfort issues, including these.

Poor Humidity Control

An air conditioning system with too much or too little capacity won’t provide good humidity control. Air conditioners with too much capacity for the size of the home have short cycles. This is because their cooling power quickly reaches the temperature on the thermostat. However, that short cycle doesn’t give the system enough time to remove moisture from the home. The result is damp air that feels uncomfortable on your skin. The high humidity also increases mold and mildew growth.

Inadequate Airflow

According to the Department of Energy, inadequate airflow is another chronic issue stemming from improper AC sizing. A system with insufficient capacity will not deliver enough cooled air to your home’s living spaces. This leads to hot and cold areas. Insufficient airflow can also lead to poor indoor air quality. A properly-sized cooling system filters all of your home’s air every 30 to 60 minutes, while an improperly sized one may take several hours to filter all of the air.

High Electricity Bills

Improper AC sizing will leave you with chronically high electricity bills. An air conditioning system with too little capacity will cycle a lot, and it will have a difficult time reaching the temperature on your thermostat. An oversized cooling system turns off and on rapidly. The powering up of the cooling system uses the most electricity. You’ll be left with utility bills 30 to 50 percent higher than you’d pay with a properly-sized cooling system.
