If you want to keep your home comfortable without wasting energy, your central air conditioning unit must be the correct size. The tonnage of air cooling capacity and BTU power usage per hour describe the size of AC units. However, a system with a higher rating is not automatically a superior unit for your home. At McGowan's Heating & Air Conditioning, we understand the importance of unit sizing.

Drawbacks of an Over-Sized AC

Cooling equipment capable of processing more air than your home holds greatly reduces energy efficiency. The problem arises because the system can cool the home very rapidly. This means that it fails to do a complete job of conditioning the air before concluding a cycle.

Short cycle problems:

  • Humidity stays too high
  • Excessive electricity usage
  • Higher utility bills
  • Reduced indoor comfort

Drawbacks of an Under-Sized AC

A central air conditioning unit with a tonnage rating inadequate for a home’s square footage experiences similar issues. The AC equipment will struggle to cool a home. This causes the running cycle to go on and on.

Long cycle problems:

  • Accelerate wear and tear
  • High energy consumption
  • High utility bills
  • Inadequate cooling

Factors That Influence Size Selection

An air conditioning contractor will take multiple issues into account when calculating an air conditioner’s size. A standard formula that uses your home’s square footage and the AC unit’s tonnage and BTU ratings establish the starting point. Additionally, a contractor must consider the local climate. The levels of heat and humidity that a system must process affect the choice. Other characteristics, like ceiling height and insulation quality, also influence the final decision.
