8 Signs Your Air Conditioner Needs Replacement

Your air conditioner can only serve you for so long, and there comes a time when the best option is to replace it.

Knowing when to get a new AC is critical as it will help you avoid the frustrations and inconveniences of relying on an inefficient unit. Here are eight signs your air conditioner needs replacement

1.    It is too old

Most air conditioners have a lifespan of between 10 to 15 years, after which it is advisable to get a new unit. If you cannot remember how old your unit is or are considering replacing your old unit, seek help from HVAC professionals like 888 Heating for guidance on the best replacement options and expert installation services.

2.    High electricity bills

Most old or worn-out air conditioners are less energy-efficient, and holding onto them will only lead to high energy bills. Opt for modern AC models that can save you as much as 20% to 40% of your cooling energy costs.

3.    Little or no airflow

If you cannot tell if cool air is blowing into the house even when near the vent, it is time to call an HVAC technician. Similarly, if your AC unit is blowing warm air instead of cool air, you’ll likely need professional assistance even as you start budgeting for a new air conditioner.

4.    Malfunctioning thermostat

A malfunctioning thermostat is an obvious sign of an underlying problem with your AC system or the thermostat itself. If this problem is persistent even after professional examination and repairs, save yourself from future troubles by replacing your air conditioner.

5.    Too much noise

Loud and unusual noises from your air conditioner are often a sign of internal damage and excessive wear out of your unit’s main parts. While experienced technicians can resolve some of these issues, it is better to consider getting a new unit if the repair or part replacement costs are too high.

6.    Strange odors

A foul smell from your air conditioner indicates an internal problem best diagnosed with an HVAC expert. These issues range from electrical problems to mold buildup that can cause illness. Based on the technician’s advice after the diagnosis, you could have to replace your air conditioner for a long-term solution.

7.    Too much humidity in the house

If your house is too humid even while the AC is on, you need to call an HVAC professional immediately. High humidity is dangerous to your family’s health, given how fast it leads to mold and mildew growth. Treat this problem as an emergency and prioritize replacing your current air conditioner to avoid similar situations in the future.

8.    Freon leak

Freon or refrigerant leak will quickly lead to performance and efficiency problems best resolved by replacing your air conditioner. These issues include:

  • Poor airflow
  • Ice building up on the evaporator coil and copper lines
  • Air conditioner blowing warm air

Freon is also poisonous and can lead to several health issues, making it critical to treat these leaks as an emergency.


Air conditioners play a fundamental role in making your home comfortable, and you need to be aware of when these units need replacement.
