How do I know if my air conditioner needs replacing?

Knowing when to replace your cooling system is critical to preserving home comfort and efficiency throughout those hot and humid summer months. Here are some obvious signs that your air conditioning unit needs to be replaced:

  • Air conditioner lifespan: Air conditioners typically have a lifespan of 10 to 15 years. If your air conditioner unit is nearing or has passed this age limit, it may be more economical to replace it with a new, energy-efficient model instead of continuing to repair and operate an older unit.
  • Frequent Breakdowns: If the air conditioner you have requires frequent repairs, it may be nearing the end of its intended lifespan. Investing in servicing on an ongoing basis may end up costing more than purchasing a new, dependable air conditioner.
  • Reduced Cooling Performance: If you recognize that your air conditioner isn't cooling your residence as well as it used to, or if specific areas are consistently warmer than others, it might be a sign of a failing AC unit.
  • Increasing Energy Bills: As air conditioner units age, their efficiency decreases, resulting in increased energy use and greater utility bills. If your cooling expenses have been growing over time, a new, energy-efficient air conditioner can help you save money in the long run.
  • Strange Noises: Unusual noises from your air conditioner, such as grinding, squealing, or banging, might point to mechanical problems or outdated parts, which may require replacement.
  • Extreme Humidity: Air conditioning units not only cool but also remove moisture from the air. If you recognize increased humidity in your home and an ongoing damp feeling, your air conditioner may be having trouble removing the humidity.
  • Bad Smells: Persistent musty or foul odours when the air conditioner is operating could be a sign of mould or mildew growth within the unit itself, which can be difficult and expensive to remove.
  • Constant Short Cycling: When the air conditioner turns on, and off frequently, it may indicate an excessive or failing system, resulting in energy waste and premature deterioration.
  • Refrigerant Leaks: If your air conditioner is losing refrigeration fluid, it won't be able to cool efficiently, and the expense of replenishing the refrigerant and repairing the leak may make changing the unit more appealing.
  • Outdated Tech: Older cooling systems may lack the most recent energy-saving technologies and features, making newer models cheaper and more effective in the long run.

What are the symptoms of a bad air conditioner?


Here are some symptoms your air conditioning system is going bad:

  • Poor Cooling Performance: The cooling system fails to cool the room or preserve the temperature you want, leaving you feeling hot and bothered even when the unit is turned on.
  • Weak Airflow: The breeze that comes from the vents is soft or feels not enough to adequately cool the room.
  • Short Cycling: The air conditioner frequently cycles on and off.
  • Strange Sounds: Noises from the air conditioner could indicate mechanical problems or parts that are worn out.
  • Leaking Water: Water or moisture around the unit inside, as well as excessive condensation, indicate a possible problem with the drainage system or a leak in the refrigerant.
  • Foul Odours: When the air conditioner is running, foul odours may indicate mould or mould development within the system.
  • High Humidity: If your air conditioner isn't correctly dehumidifying the air, you might experience increased humidity inside and a damp feeling.
  • Tripped Circuit Breakers: Regular tripping of circuit breakers while the air conditioner is on, indicates a wiring issue or overload.
  • Frozen Evaporator Coil: If the evaporator coil within the indoor unit has been encased in ice, it could suggest an airflow or refrigeration fluid problem.
  • Problems with the Thermostat: the cooling system does not respond to thermostat settings, or the temperature demonstrated on the thermostat does not correspond to the actual temperature inside.

If you notice any of the above signs, it's critical to address the problem right away to avoid further damage and keep your air conditioner running efficiently. Regular maintenance, at least once a year, is also recommended to prevent damage in the first place.

How often does an AC need to be replaced?

The service life of an air conditioning system is affected by a number of factors, including the unit's quality, how well it is maintained, how frequently it is used, and the environment in which it operates. Air conditioners typically have an average lifespan of 10 to 15 years. However, with adequate upkeep and regular maintenance, some units can last even longer.

If the air conditioner you have is 10 to 15 years old, and you notice signs of deteriorating performance or increased repairs, it may be time to start thinking about replacing it. Furthermore, if the cost of repairs is becoming excessive, investing in a new, energy-efficient unit will save you money over time.
