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 11 signs your air conditioner needs replacement

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.

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 20% to 40% of your cooling energy costs.

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 need professional assistance even as you start budgeting for a new air conditioner.

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.

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.

Strange odours

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

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 mould and mildew growth. Treat this problem as an emergency and prioritise replacing your current air conditioner to avoid similar situations in the future.

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.

Frequent air conditioner repairs

If you realise that you have had to repair various heating and cooling system components in the recent few months, you should consider replacing the unit. You do not have to keep paying for repairs if they are only extending the life of your air conditioning system for a short span. While replacing the unit may be on the high end of your budget, it is more economical in the long term.

The AC is blowing warm air.

Your HVAC system should keep you and your family comfortable when exterior temperatures climb. If the unit is blowing warm air, it’s not providing ideal indoor temperatures. This could indicate your air conditioner is low on refrigerant or has issues with the compressor. If the repair is too expensive, consider replacing it.

Frequent cycles

Typically, the air conditioner goes through regular cooling cycles regardless of the weather. The cooling system also turns on more during hot and muggy summer days, but it should not cycle on and off frequently. If you notice your unit frequently cycles, hire a cooling expert for a quick tune-up. It could also mean you need a new air conditioning system.
