Air conditioning equipment typically lasts approximately 15 years. Knowing when your AC has reached the end of its useful life can save you a lot of stress and money. Below are the key signs to watch out for.
1. Insufficient Cooling
ACs are primarily designed to cool indoor spaces. If your unit can’t do that effectively, it could be a sign to replace it. Granted, some causes of insufficient cooling are minor and easily fixable, like dirty air filters or malfunctioning or misconfigured thermostats. However, serious issues like a failing compressor and frequent refrigerant leaks may signal that the AC has reached the end of its lifespan.
The compressor is a core component of the AC. When malfunctioning frequently, it’s advisable to replace the entire system. Swapping out the compressor can lead to compatibility issues, where the new component outperforms and strains older, worn parts. You could end up spending a substantial amount of money on repairs and replacements.
Improper sizing may be a problem after remodeling your home. For instance, removing a wall or adding square footage can change the cooling load requirements of your space. If the existing AC system wasn’t updated to match the new layout or square footage, it might struggle to maintain consistent temperatures.
Refrigerant leaks are often caused by worn-out coils, excessive system vibrations, or poor connections in aging units. If your AC system uses phased-out refrigerants like R-22, R-410A, or R-134a, you may run into difficulties with refills because the government highly discourages the manufacture and sale of these compounds.
2. Strange Noises and Odors
Unusual noises or odors coming from your AC are clear indicators that something’s wrong and needs immediate attention. A licensed technician can inspect the system and identify whether the issue is minor or serious. Just as with efficiency problems, the cause of the noises and odors may be fixable.
However, if the strange sounds and smells occur repeatedly despite repairs and routine maintenance, it may be time to consider replacement. Rattling or banging noises often point to issues like loose components, a failing fan motor, or a malfunctioning compressor. Clicking sounds are typically associated with a failing capacitor. A capacitor’s role is to give the AC the initial power it needs to start and run properly. When there is a problem with the capacitor, the system may struggle to turn on, short-cycle, or fail to cool properly.
Problematic odors include burning smells, chemical-like odors, and musty scents. A burning smell may signal electrical issues such as overheating wires or a failing motor. Chemical-like odors can indicate refrigerant leaks, while musty smells suggest mold, mildew, or fungal growth within the system.
3. Rising Energy Bills
A steady increase in your energy bills without a corresponding rise in AC usage is a sign that your system may be losing efficiency. The internal components may have deteriorated to the point where the AC must work harder and longer to achieve the same cooling output.
Other causes of excessive energy consumption include poor home insulation, ductwork issues, and poor airflow. If your home is easily impacted by the outdoor environment due to insufficient insulation, even a new and highly advanced AC will be inefficient. You must address insulation problems first before repairing or replacing your AC because it may regain much of its efficiency.
Similarly, leaky or poorly sealed ductwork can waste cooled air before it reaches your living spaces, undermining your system’s performance. If left unaddressed for a while, the deterioration of internal components could be too significant to repair. System replacement could be the only viable solution.
4. Frequent Repairs
It’s normal for an AC to require occasional repairs. We try to spot issues during your regular maintenance appointments. The purpose of routine maintenance is to prevent issues before they arise. Our technicians perform a wide range of tasks, including cleaning coils and ducts, sealing ductwork, tightening electrical connections, lubricating moving parts, replacing worn components, topping off refrigerant levels, and changing filters. If problems continue despite these efforts, it likely means the system is deteriorating substantially, and replacement may be a cost-effective solution.
5. Old Age
If your AC unit is approaching or has passed the 15-year mark, it’s time to start planning for a replacement. We can assess the condition of your equipment during routine AC maintenance.
