A major change in the industry is the efficiency of AC systems. Modern units are at least 30% more efficient than models prior to 2006. Another evolution in air conditioners is the type of refrigerant used. The previous standard refrigerant is called HCFC-22 (commonly known as R-22), which has since been determined to have a negative impact on the ozone layer. This refrigerant is in the process of being phased-out following a mandate from the Environmental Protection Agency (EPA). If your system uses this refrigerant, it will eventually need to be replaced for a higher efficiency model.
The new refrigerant used by modern systems is R410-A, which is both more efficient and more environmentally friendly.
BELOW ATE A FEW REASONS TO REPLACE CURRENT AIR CONDITIONING SYSTEM
The system is more than 10 years old
If your air conditioner is more than 10 years old, you should consider replacing it. According to research by EnergyStar, newer, more energy-efficient units can save up to 20 percent on heating and cooling costs. How’s that for incentive?
The cost of repairs is more than the price of a new unit
Air conditioning units that are not working adequately will fail to evenly cool a house or even a room. Sometimes it’s just a relatively minor or inexpensive repair to get the unit running properly again.
Other times, the cost of repairing a worn out system can be as much as the price of a new unit, in which case it makes sense to upgrade to a new air conditioner.
Your home’s too humid
A properly-functioning air conditioning system works to reduce humidity in your home during the summer. If you notice excess moisture in your house, it’s probably due to poor performance, leaky ductwork and/or insufficient equipment, which means it may be time to replace your old unit.
You notice excess dust
If your air ducts are leaking, dust and debris from dirty places in your home (such as your attic and basement) could be circulating through your house, reducing air quality and making your family members feel sick.
