According to a UN Report, Published in 2020, Having an Efficient Air Conditioner Can Prevent the Emission of Greenhouse Gases
Cooling technology has become increasingly important for the world due to climate variations. It protects, for example, people from extreme heat, helps keep food fresh, and is essential for storing vaccines and medications. More than comfort, air conditioning has become an essential item for human well-being. But how can you tell when it’s time to replace the unit?
According to a report by the United Nations (UN), published in 2020, having an energy-efficient and environmentally friendly air conditioner could prevent the emission of up to 460 billion tons of greenhouse gases over the next 40 years. Currently, according to the document, it is estimated that there are 3.6 billion units in use, a number that could rise to 14 billion by 2050.
The decision to replace the equipment goes beyond technical issues and signs of failure. It is also about considering the sustainability of the planet, improving the quality of life, and the savings that an efficient unit can generate.

Next, see five signs that it’s time to replace your air conditioner!
1. Is The Air Conditioner Over Ten Years Old?
This may seem obvious, but if the air conditioner is becoming outdated, it is important to start preparing for the purchase of a new unit. These products are often exposed to extreme temperatures throughout the year, which can reduce their durability.
The lifespan can also be affected by how often you use the equipment, whether proper maintenance is performed, how hot and humid it gets in your area, and whether the unit was properly sized at the time of purchase. Those living in coastal cities, for example, need to take extra care because of the salt air that can damage the product.
For those who keep the air conditioner in good condition throughout its lifespan, the replacement timeframe can range from ten to 15 years.
2. Does The Air Conditioner Break Frequently?
Frequent breakdowns are also signs that it may be time to replace the unit. In fact, with rising repair costs, purchasing a new unit may be more economical.
Typically, repair costs can be high, especially if the unit’s warranty has expired. If the damaged part is a compressor, for example, getting a new air conditioner may be more feasible.
But before making a decision, it is essential to consult a technician for a detailed analysis.
3. Is The Air Conditioner Noisier Than Before?
Another important sign may be related to increased noise. If the unit starts emitting loud noises, it is necessary to obtain an evaluation from a qualified technician to identify if there is any issue.
It could be dirt in the filter, poor performance of a part, wear and tear over time, among other issues. And, depending on the professional’s assessment, it might be time to replace it with a new model.
Problems with the equipment can even lead to other damages, such as higher electricity consumption.
4. Are Electricity Bills Dramatically Increasing?
Unless there is a sudden change in energy usage at home or an increase in rates by the government, it’s common for electricity bills to remain around the same amount each month, fluctuating slightly in the summer.
However, if the monthly bill has dramatically increased, it may be time to consider acquiring a new air conditioner.
This is because higher electricity bills can indicate that the unit is malfunctioning or losing efficiency. Increased energy consumption occurs as the product ages, so the two issues may be related.
5. Is The Air Conditioner No Longer Working As Before?
One of the main signs that the air conditioner needs to be replaced is noticing that it no longer cools the environment as it used to. While comfort regarding temperature is highly personal, it is possible to perceive when the unit is underperforming.
In these cases, when the unit is split and does not cool adequately, the most common issue is a lack of refrigerant due to a small leak in the cooling system. Other possible causes may include:
- Electrical failure;
- Dirty filters;
- Blocked air vents;
- Inadequate capacity for cooling the room;
- Open doors and windows in the room.
Besides identifying issues that may indicate it’s time to replace the air conditioner, it is essential to schedule a visit with a qualified company before buying a new unit. During the site assessment, the most suitable model and capacity for your needs are typically recommended.
This kind of care contributes to the sustainability of your wallet, the equipment, and the planet.
