Are you considering replacing your old AC unit? What you should know before buying a new one and what are the benefits to upgrade your HVAC system.
Today’s best air conditioners are energy efficient using between 30% to 50% less energy than the air conditioners from the mid 1970’s.
Even if your house has a ten-year-old air conditioning unit, and is fairly new, upgraded versions may save you up to 20% to 40% of your cooling energy bill. That being said, the decision to replace your older or relatively newer unit will depend on your specific needs and budget.
An air conditioners performance, efficiency, durability, and initial cost depends on matching its size to these factors:
- The size of your home and number of windows.
- The amount of shade your home windows provide as well as walls, and type of roof.
- The amount and type of insulation are in the walls, ceilings, and attic of your home.
- The number of air leaks from defective windows and groves throughout the entire house.
- The amount of appliance heat and occupants generate while indoors.
- The proper size unit is in accordance with the square footage of the property. Larger air conditioners do not always provide the best cooling.
Over-sized air conditioners serve the following consequences:
Besides costing more, larger air conditioners will cycle on and off more frequently, reducing its efficiency. Frequent cycling makes indoor air temperatures change more, resulting in a less comfortable environment. Frequent cycling also reduces moisture removal critical for human comfort. Over sized air conditioners will drop indoor temperatures quickly, satisfying the thermostat without running long enough to remove the moisture. A normal range of 50% is relatively humid but leaves the inside of the home cold and damp. (A very uncomfortable feeling.)
This cycling also wears out electrical parts more rapidly, such as the compressor. Also, a larger AC unit will use more electricity and create added demands on electrical generation and delivery systems.
