If you’re installing a new HVAC system in your home, don’t assume that every contractor will do the job properly. Many homes in Westwego, Louisiana, have HVAC systems installed that are either too big or too small. Both will affect the system’s efficiency and your home’s comfort level.

Common Problems With an Oversized Unit

AC systems are designed to lower temperature and dehumidify. To do the latter, an AC has to run a cycle long enough to remove moisture from the air. Oversized systems reach the target temperature too quickly and shut off before finishing the dehumidifying process. With the humidity levels in Gretna, Louisiana, you’ll be sticky and uncomfortable all through summer.

The rapid cycling of an oversized unit also results in the following:

  • Uneven temperature distribution. One part of the house heats or cools properly while another remains too hot or cold.
  • Higher energy usage that increases your bills.
  • More wear and tear that leads to frequent HVAC repairs and shortens the lifespan of the unit.

Inefficient Heating and Cooling With an Undersized Unit

An undersized system struggles to heat and cool a home. Because of its small capacity, it will have to work harder and longer to reach the target temperature but never reach it. Again, this affects your home’s comfort level. ┬áPlus, a long-running HVAC system will inevitably result in increased energy bills. Additionally, the strain on the system will increase its maintenance cost and adversely affect its durability.

How to Properly Size an HVAC Unit

A good HVAC contractor should follow the Manual J load calculation set by the Air Conditioning Contractors of America (AACA). It takes into consideration factors such as the house’s square footage, ceiling height, the number of windows, insulation, and weather conditions.

Installing a new HVAC system is a big investment. That’s why it’s important to choose the right contractor. At Bryans United Air Conditioning, our HVAC technicians are trained to correctly size HVAC equipment to meet the needs of your home. Call us today for an assessment.
