There is not a set size that can be recommended. Every home is different, and there are many environmental variables that must be taken into account. New higher efficiency A/C systems need proper airflow to meet their designed efficiency levels. A load calculation must be performed on the home to determine the proper system size that meets all the physical requirements. Ultimately the size determination should be made by a qualified air conditioning specialist.

More than likely the air conditioner is undersized and/or working harder to keep to the desired indoor design temperature. An air conditioner works properly and efficiently at the temperature it was designed to achieve during installation. If there are hotter than normal days, the A/C will try to maintain the indoor design temperature. This does not necessarily mean there is an undersized unit. It means that the particular hot day is outside the normal range of the calculated design for the A/C unit. A proper load calculation from an air conditioning contractor can determine if the air conditioner is properly sized for the geographic location.

Normal temperatures in the summer can fluctuate depending on the region. If the thermostat is set at the desired temperature during the day, consider a 10 degree lower temperature at night. Most automatic thermostats have intelligent recovery which enables the thermostat to lower the temperature gradually, so the night time savings is not lost by manually bringing down the temperature all at once. These programmable thermostats also help to optimize energy savings without sacrificing comfort.

Icing on the condenser coil on the indoor portion of your air conditioner, or ice on the refrigerant lines outside can be caused by several conditions. The most common culprit is reduced or restricted airflow from a dirty air filter or restricted air ducts. In some instances, a refrigerant (commonly called Freon) leak can cause a condition where ice accumulates on the indoor coil. This condition may damage your system so it should be fixed.

You deserve to be comfortable, home comfort really starts with a matched system. A matched system is made up of components that are designed to work together to provide greater efficiency, reliability and comfort. Your home's air is pulled through a return duct into the furnace. If an air filtration system is present, the air first passes through the filter and is cleansed. When heating, the air is then circulated through the heat exchanger where it is heated to the temperature set by the thermostat. A blower then pushes the air into the duct system, where it blows out of the vents and circulates throughout the home. When cooling, the air pulled into the system from the return grill is cooled by the air handling unit, usually located inside the home. This equipment uses refrigerant to remove the heat from the air. The blower then pushes the cooled air into the duct system and out to the rooms of the home.
