How To Extend The Lifespan Of Your Refrigerator

A refrigerator is one of the hardest working appliances in any home—running 24/7 to keep food fresh, beverages cool, and frozen goods at the right temperature. It’s no surprise, then, that protecting your investment and ensuring your fridge operates efficiently for years to come is a top priority for many homeowners. Whether you’ve just purchased a new unit or are looking to get the most out of an existing one, there are simple and effective ways to increase your refrigerator lifespan.

This guide covers essential maintenance tips, common issues to watch for, and the role professional servicing can play in prolonging the life of your fridge. Let’s dive in.

The typical refrigerator lifespan falls between 10 and 20 years, depending on how it’s maintained and how it’s used. Over time, wear and tear on key components like the compressor, condenser coils, and fans can take a toll. Without proper care, even high-quality refrigerators can begin to show signs of strain early. That’s why preventative maintenance is so important—it keeps the system running smoothly, maintains energy efficiency, and reduces the risk of breakdowns.



While there’s a lot of advice online about DIY maintenance, the safest and most effective way to preserve your refrigerator is to engage qualified refrigeration technicians. This ensures the job is done correctly, with no risk of damaging internal components or voiding warranties.

Staying on top of maintenance is the easiest way to support long-term performance. While homeowners play a role in caring for their appliances, certain tasks should always be handled by professionals—especially when it involves electrical systems, refrigerants, or internal mechanisms. Here's how professional servicing can help maintain your refrigerator:

Over time, dust and debris collect on the condenser coils, forcing the fridge to work harder. This reduces efficiency and puts strain on the compressor. A technician can safely access and clean these coils using the correct equipment and methods, which also avoids accidental damage to surrounding components.

Leaking door seals cause cool air to escape, leading to inconsistent temperatures and wasted energy. During a professional service, seals and hinges can be inspected, cleaned, or replaced as needed. Technicians know what to look for and can identify early signs of wear that may be missed during a casual check.

Professionals can verify that the refrigerator is maintaining the ideal temperature range. They can also test sensors and thermostats to ensure everything is working correctly. In some cases, recalibration or part replacement may be needed to restore proper function.

Poor airflow within the fridge can cause uneven cooling or freezing in certain areas. A technician can assess whether internal components are blocked or whether the fan system is functioning as it should. Ensuring proper airflow extends both food life and appliance performance.

A fridge that isn’t level may have trouble sealing properly and can even affect compressor function. Drain lines also need to remain clear to prevent water buildup or leaks. These checks are best carried out by a refrigeration specialist who can make precise adjustments and spot issues before they become bigger problems.

Being proactive helps you avoid the most common refrigerator issues before they become serious.

Blocked vents lead to uneven temperatures and may cause sections of the fridge to freeze or spoil food faster.



Solution: Check that nothing is pushed up against the vents inside your refrigerator or freezer compartments.

Buzzing, clicking, or loud humming may signal a failing component. Early diagnosis can prevent total breakdowns.



Solution: If the noise is persistent or unusual, it’s best to call a refrigeration technician to inspect the unit.

Condensation inside the fridge could point to worn door seals or high humidity settings.



Solution: Keep door seals clean and dry, and check that the fridge isn’t left open for long periods.

Placing a refrigerator in direct sunlight or too close to heat sources (like ovens or dishwashers) makes it work harder.



Solution: Choose a cool, shaded location and ensure there’s at least 5–10cm of space around the fridge for ventilation.

There are many benefits to having your refrigerator professionally maintained. Beyond keeping the appliance running efficiently, regular servicing helps prevent sudden breakdowns and extends the overall lifespan of the system.

A qualified refrigeration technician will be able to:

• Diagnostic checks: Professionals can test your fridge’s performance, identify worn-out parts, and address any inefficiencies.
• Refrigerant levels: Low refrigerant can reduce cooling efficiency and increase strain on the compressor. A technician can assess and top up levels if needed.
• Electrical inspection: Loose wires, faulty thermostats, or damaged control boards can all shorten your refrigerator's life. A trained professional can test these systems safely.
• Compressor & fan checks: These components are vital to the fridge’s operation and need to be running smoothly. A professional can clean, test, and repair them as needed.



A qualified technician will know what to look out for and how to maintain systems for longevity.

Strange sounds or smells coming from your air conditioner could indicate an underlying issue that needs immediate attention. Ignoring these signs may result in serious system damage or costly repairs.

• Grinding or squealing noises – Could indicate a worn-out motor or belt.
• Rattling or banging sounds – May suggest loose components inside the unit.
• Musty or mouldy smells – Often a sign of mould growth in the ducts or drain pan.
• Burning odour – Could indicate an electrical problem that requires urgent professional attention.

If you notice any of these warning signs, scheduling a professional inspection as soon as possible can prevent further damage and ensure safe operation.

Even with excellent care, there comes a point where replacing your refrigerator is more cost-effective than continuing to repair it. Signs it may be time for a new unit include:

• It’s over 15 years old and running inefficiently.
• Food is spoiling quickly despite correct settings.
• The compressor or motor has failed more than once.
• Repair costs exceed half the price of a new fridge.
• Energy bills are rising with no other explanation.



If you do need a replacement, opt for an energy-efficient model that meets your household’s needs and ask your technician for recommendations specific to your kitchen layout and usage.

Your refrigerator works hard every day to keep your food safe and fresh, so it makes sense to return the favour with a little care and maintenance. By taking simple steps and scheduling professional checks, you can significantly extend the refrigerator’s lifespan and avoid unnecessary breakdowns.
