The Importance of Properly Sizing a Central Air Conditioner

When a new central air conditioner is installed in a home one of the most important tasks the HVAC technician performs is matching the size of the unit to the amount of air being conditioned. If the unit is too large for the home, problems can occur.

Some of the symptoms of an air conditioning system that is sized too large for the house include the inability of the unit to adequately dehumidify the home and powering on and off too frequently. This occurs because an overly large system will cool the air so quickly that not enough humid air is allowed to flow over the cooling coil to remove the moisture from the air. The thermostat quickly reaches the set temperature and shuts off, leaving too much humidity in the air. The only practical solution is to install a properly sized condensing unit and coils.

Have questions about your home’s central air conditioner? Call ABC Plumbing, Heating, Cooling and Electric, we’re here to help.
