How does an AC unit work?

Air conditioning units remove heat from the air and transfer it outside, leaving the air inside your home cool and comfortable. The main components of an AC unit are:

  • Compressor: The AC system’s compressor is its heart. It compresses the refrigerant gas, increasing its temperature and pressure.
  • Condenser: The high-pressure refrigerant gas is converted into a high-pressure liquid in the condenser. As the refrigerant condenses, heat is discharged into the atmosphere.
  • Evaporator: The high-pressure liquid refrigerant then travels to the evaporator within the house, where the refrigerant chills the air as it dissipates by absorbing heat.
  • Refrigerant: The chemical refrigerant absorbs and releases heat as it changes from a gas to a liquid and then back to the gas as it travels within the air conditioner.

These are the essential components of an air conditioner and how they function to cool inside air. They must receive the proper maintenance for an AC unit to operate effectively and efficiently.

Signs That You Need a New AC Unit

A new air conditioner may be necessary if your AC unit shows wear and tear symptoms over time. It would be best if you watched out for the following typical signs:

Age of the Unit

The average lifespan of an AC unit is 10 to 15 years. It’s time to consider replacing the equipment if it has reached this age. Older units might not chill your home as effectively, leading to more significant energy costs and less comfort.

Reduced Cooling Performance

If your AC unit is not cooling your home as effectively as it used to, it may be a sign of a declining system. Reduced cooling performance can result in uneven temperatures throughout your home.

Higher Energy Bills

If you notice a sudden increase in your energy bills without significant changes in your energy usage, it may indicate that your AC unit needs to be operating more efficiently. Older or poorly maintained units can consume more energy, resulting in higher bills.

Strange Noises or Odors

If your AC unit is making unusual noises or emitting strange odors, it may indicate a problem with the unit. Unusual noises could be due to loose or damaged components, while strange odors could indicate mold growth or a refrigerant leak. These issues may require costly repairs, and replacing the unit may be more cost-effective.

Poor Indoor Air Quality

Your AC unit may need to be fixed if you observe dust, grime, or pollen rise in your home. Air filters built inside AC units assist in removing airborne impurities. If your unit is not effectively filtering the air, it may be time for a replacement.

Outdated Technology

Advancements in AC technology have led to more energy-efficient and environmentally friendly units. Let’s say your air conditioning system is old and does not have contemporary features like programmable thermostats, variable-speed compressors, or smart home connectivity. Then it can be worthwhile to update to a newer one that might offer more comfort and energy efficiency.


Making decisions about your air conditioning system can be easier if you know how an AC unit operates and can spot warning signs that you need to replace it. Consider purchasing a new AC unit if your current unit is prone to breaks, performs poorly at cooling, costs more to run, produces poor indoor air quality, or exhibits other problems. A qualified HVAC technician can evaluate your needs, suggest an appropriate AC unit for your space, and provide expert installation services if you need air conditioning service in Auburn, New York. With a new AC unit, you may enjoy a cool, comfortable indoor atmosphere during the hot summer.
