When To Replace Your Central Air Conditioning Unit

The central air conditioning system circulates cold air through the air supply ducts and returns ducts. This system removes excess heat and moisture from your home, cleans the air, and keeps the space more comfortable.

A central system that is not running at its best performance can be costly and less comfortable in hot weather, leading to a stressful experience for the homeowners. Air conditioning units can have a longer lifespan. This is possible if they’re well maintained and any repairs are made on time.

However, the life expectancy of an air conditioner depends on several factors, including:

  • Air conditioner type
  • Unit size
  • System quality
  • Unit maintenance degree

Signs Your Central Air Conditioner Needs To Be Replaced

We’ve compiled a list of the five most important factors in deciding when to replace a central air conditioner. If you notice any of these at home, contact the AC service in Gainesville to determine if you need a system repair or a new system entirely.

Improper Air Coming Out of the Vents

If the air coming out of the vents appears slightly out of alignment, it may indicate a serious problem with the central air conditioning system. For example, you may find that the sudden air feels warm. A central air conditioner that blows warm air means something is broken in the system. It could be a compressor failure or various other causes.

Inconsistent Temperature and Humidity

One of the features of the central air conditioner is to remove the moisture in the house. If some rooms are more humid than others, you may need to repair or replace the central air system.

Running Too Loud

Central air conditioning is known for being completely quiet. However, if you hear a humming or rattling noise in your house, your system may not be working at its highest efficiency. The internal coil system of the indoor unit may be defective or malfunctioning. Or the duct system is not well enough for the central air system.

Rising Costs

Electricity bills for heating and cooling homes account for about 44% of utility bills, but aging systems can increase overall utility bills. The system’s inefficiency means that more energy is used to maintain the same temperature and comfort level in the house. The new central air conditioner can save you money in the long run.

Dust in the Air

The area of the duct system should be clean and dust-free. If the duct cracks, dust can get in from inside the house’s foundation and float in the air from the central air conditioning system. If dust continues to accumulate throughout the house, it may be a sign that the central air conditioner or duct system needs repair or replacement, especially after cleaning.
