Is it time to upgrade your old AC? When considering new equipment to cool your home, you need to choose a unit that is the right size to achieve maximum comfort and energy efficiency. 

Choosing a unit that is too big can cause problems.  

Many people assume that the bigger the unit the zoned HVAC systems 1cooler their home will be. This isn't true. If an air conditioner that is too large is installed, you could have a problem. Over-sized equipment is actually less effective and also wastes energy and money.

Air conditioners remove heat and humidity from the air. If the unit is too large, it will cool the room quickly, but only remove some of the humidity. This leaves the room with a damp, clammy feeling. A properly sized unit will remove humidity effectively as it cools.

When the air passes over the evaporator coil which is very cold, the temperature drops about 20 degrees. In Columbus and Central Ohio, where we have high relative humidity levels, the evaporator coil doesn't just cool the air but also acts as a dehumidifier. This happens when the air hits the coil and the temperature of the coil is below the dew point of the air.

This causes water vapor to condense on the coil. With a cooling unit that is too large, water vapor condenses on the coil but you don't get enough condensation on it for the water to start dripping down into the pan below the coil. If this happens the water isn't drained to the outside. Then your home has a damp clammy feeling.

An AC that is too big can also be more expensive to buy and to operate. It will start and stop more often, thus shortening the lifespan of the equipment.

When a cooling system is over sized, it starts up and shuts down a lot more because it runs for only a short time to meet the thermostat set point. All those starts and stops mean you'll probably be repairing it more often and replacing it sooner.

Buying the correct size equipment for your home will not only save you money on the initial purchase, but also on save you money on energy costs and equipment repairs.
