You turn on the air conditioner after months of disuse, and then: lukewarm 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 heatwave episodes sometimes push the thermometer well beyond. This past July 14, the National Meteorological Office placed Oran on heatwave alert, alongside Algiers, Mostaganem, and Aïn Témouchent. In 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 a home has been closed for several months, 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 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 AC technicians, who are very busy as soon as the first heatwaves hit.
- 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 that trigger too often. It's better to intervene early than to wait for a complete breakdown in scorching 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 are greatly extended. Have your units checked in the spring, even if everything seems to be working: preventative maintenance always costs less than a breakdown during a heatwave.
Signs that the AC is no longer cooling effectively
Certain symptoms should raise a red flag even before a complete breakdown occurs.
| Symptom | Probable Cause |
|---|---|
| Lukewarm instead of cold air | Clogged filter, low refrigerant gas, obstructed outdoor unit |
| Abnormal noise or vibration | Loose part, unbalanced fan, foreign object in the unit |
| Unpleasant odor at startup | Mold or dust accumulated in the filter and heat exchanger |
| Water leaking indoors | Clogged or improperly sloped drain pipe |
| Increased electricity bill | Clogged unit consuming more for the same result |
The maintenance checklist, step by step
Comprehensive maintenance follows a precise order to ensure nothing is overlooked.
✅ Pre-summer maintenance steps
- Cleaning or replacing filters: the most important and most neglected element. A clogged filter significantly 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 greatly reduces efficiency and requires a professional equipped for recharging.
- Checking condensate drainage: the drain pipe must not be clogged, otherwise water may leak indoors.
- Full startup test: turn on the unit at least 30 minutes before intended intensive use, to detect any problems before the first hot day.
- Electrical check: wiring, outlets, 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 perfectly dry before reinstallation), exterior 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 leaks or faulty compressors.
If your apartment has been closed for several months, air conditioning maintenance naturally integrates into a complete restoration of the property. Our guide cleaning an apartment that has been closed for several months covers the entire protocol, including dust and humidity.

Why is my air conditioning no longer cooling in Oran?
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 I have my air conditioning maintained before summer?
Ideally in May or early June, before temperatures rise and before technicians are overwhelmed with requests during a heatwave.
Can I clean air conditioning 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 is low on refrigerant gas?
Air blowing but remaining lukewarm, even after long operation, is the most common sign. Only an equipped professional can confirm the diagnosis and perform a safe recharge.
Is air conditioning maintenance necessary if the apartment has been closed all year?
Yes, especially in this case. Dust accumulated during the absence clogs the filters and the outdoor unit much more than regular use, and increases the risk of breakdown on the first startup.
How long does a full air conditioning maintenance take?
Typically allow 30 to 60 minutes per unit for full maintenance, including filter cleaning, outdoor unit check, and refrigerant gas control.
