You switch on the air conditioner after months of disuse, and then: warm air, a suspicious noise, or worse, nothing at all. In Oran, this moment happens every year at the worst possible time, just as temperatures rise and the diaspora returns for the summer. Air conditioner maintenance before summer avoids this scenario and usually takes less than an hour per unit.

Why pre-summer maintenance is essential in Oran
Oran summers are no joke. In July and August, temperatures regularly exceed 30 to 32 °C in the afternoon, and heatwaves sometimes push the thermometer well beyond that. The National Meteorological Office has already placed Oran on heatwave alert, alongside Algiers, Mostaganem, and Aïn Témouchent. Under these conditions, a malfunctioning air conditioner is not just an inconvenience: it's a real problem for comfort, and sometimes health, especially for children and the elderly.
For the diaspora returning for the summer after several months of closed accommodation, the air conditioner is often the first appliance tested, and the first to disappoint. An appliance clogged with accumulated dust during absence significantly loses efficiency, consumes more electricity, and is much more likely to break down at the worst possible moment.
When to perform air conditioner maintenance
Good timing makes all the difference between hassle-free maintenance and an emergency in the middle of a heatwave.
- Ideally in May or early June, before temperatures rise and before the peak demand for refrigeration technicians, who are heavily solicited as soon as the first warm weather arrives.
- Before each return to the accommodation if the apartment has been closed for several months: dust accumulated in the filters and the outdoor unit significantly reduces performance.
- At the first signs of weakness: less cold air, unusual noise, odor, cycles triggering too often. It's better to intervene early than to wait for a complete breakdown in high heat.
💡 Karim's advice
Never test your air conditioning for the first time of the year on a 40-degree day. At that point, all the technicians in the city are overwhelmed, and intervention times become very long. Have your units checked in spring, even if everything seems to be working: preventive maintenance always costs less than a breakdown during a heatwave.
Signs that the air conditioner is no longer cooling well
Certain symptoms should raise an alert even before a complete breakdown.
| Symptom | Probable cause |
|---|---|
| Warm air instead of cold | Clogged filter, lack of refrigerant gas, obstructed outdoor unit |
| Abnormal noise or vibration | Loose part, unbalanced fan, foreign object in the unit |
| Unpleasant odor on startup | Mold or dust accumulated in the filter and heat exchanger |
| Water leaking indoors | Blocked or improperly sloped drain pipe |
| Rising electricity bill | Clogged unit consuming more for the same result |
The maintenance checklist, step by step
Comprehensive maintenance follows a precise order, leaving nothing out.
✅ Pre-summer maintenance steps
- Cleaning or replacing filters: the most important and most neglected element. A clogged filter severely reduces airflow and cooling capacity.
- Checking the outdoor unit: clear leaves, dust, and debris accumulated around the condenser, which hinder heat exchange.
- Checking refrigerant gas level: a lack of gas significantly reduces efficiency and requires a professional equipped for recharging.
- Checking condensate drainage: the drain pipe must not be blocked, otherwise water will leak indoors.
- Complete startup test: turn on the appliance at least thirty minutes before expected intensive use, to detect a problem before the first hot day.
- Electrical check: wiring, sockets, and dedicated circuit breaker, especially if the dwelling has been closed for a long time.
What you can do yourself, and what requires a professional
Not all maintenance necessarily requires a technician.
- Yourself: cleaning filters with soapy water (they must be completely dry before reinstallation), external dusting of the unit, clearing debris around the outdoor condenser.
- A professional: checking and recharging refrigerant gas, disassembling the heat exchanger for deep cleaning, electrical diagnostics, repairing a leak or a faulty compressor.
If your apartment has been closed for several months, air conditioning maintenance is naturally part of a complete property overhaul. Our guide cleaning an apartment that has been closed for several months covers the entire protocol, including dust and humidity.

Why isn't my air conditioning cooling anymore?
The most frequent causes are a clogged filter, a lack of refrigerant gas, or an outdoor unit obstructed by dust accumulated during the months the property was closed.
When should air conditioning be serviced before summer?
Ideally in May or early June, before temperatures rise and before technicians are overwhelmed with requests during a heatwave.
Can I clean the filters myself?
Yes. Cleaning with soapy water, followed by complete drying before reinstallation, is usually sufficient for filters. It is the simplest and most effective step to restore good performance.
How do I know if my air conditioning needs refrigerant gas?
Air that blows but remains warm, even after long operation, is the most common sign. Only a equipped professional can confirm the diagnosis and perform a safe recharge.
Is maintenance necessary if the property has been closed all year?
Yes, especially in this case. Dust accumulated during absence clogs the filters and outdoor unit much more than regular use, and increases the risk of breakdown at the first startup.
How long does a full maintenance take?
Generally allow 30 to 60 minutes per unit for full maintenance including filter cleaning, outdoor unit inspection, and refrigerant gas check.
