Are you looking to purchase a new air conditioning unit? Is your current unit over ten years old, then it is time for a new one. During this time, the amount you can save will add up to more than the cost of a new unit.
When purchasing a new air conditioning unit, it is important to properly size the unit to fit your space, because an undersized or oversized unit will have a slew of drawbacks
- UNDERSIZED An undersized unit will struggle to keep your home or commercial space cool and will constantly run to try to keep the thermostat satisfied. The constant running will reduce pressure in the evaporator cooling coil until it eventually freezes. It becomes a domino effect because a frozen coil can lead the liquid refrigerant in the system to flood back into the compressor and damage it. You have already invested money on a new air conditioning unit so it doesn’t make sense now to have to buy a new compressor.
- OVERSIZED An oversized air conditioner will be susceptible to shorter cycling, inadequate dehumidification, as well as large temperature variations throughout the space. These units will have a shorter life span and provide less comfort to the area. Most notably, the humidification level will stay higher. As the temperature drops quickly with an oversized unit, there is not enough air movement across the coil to extract water from the residential or commercial space. Ask your contractor if he uses the sizing manual put out by the ACCA, Air Conditioning Contractors of America as his guideline. He should measure your space and take into considerations skylights, trees, and direction of space, ceiling height, and other important factors like gauge of insulation and number and age of windows.
Here are other basic criteria to use when choosing a new air conditioning unit -
- BTUs: This is the cooling capacity of an air conditioner. It is measured in British thermal units Per hour.
- Energy Star Rating: The rating is calculated based on information about a building, such as its size, location, number of occupants, number of computers, and more. The rating system estimates how much energy the building would use if it were the best performing, the worst performing, and every level in between. The system then compares the actual energy data you entered to the estimate to determine where your building ranks relative to its peers.
- EER: Energy-Efficiency Ratio is simply the ratio of cooling output divided by the units consumption. The higher the EER, the more efficient the unit is.
