Maintaining your air conditioner before summer means preparing it for the peak operating period of the year: cleaning the filters and indoor and outdoor coils, ensuring proper drainage, and checking the refrigerant pressure, electrical connections, and fans. An air conditioner that enters summer with dirty filters and coils loses some of its actual capacity and runs longer, increasing electricity consumption and the likelihood of breakdowns during the hottest part of the day.
- The filters are cleaned periodically, and more frequently during dusty seasons.
- The outer coil (condenser) is washed of dust so that it expels heat efficiently.
- A blocked drain causes water to leak into the room.
- Checking Freon, electricity, and electrical capacitors is a specialized technical task.
- Facilities with large systems benefit from a maintenance contract with scheduled visits.
Why maintain the air conditioner specifically before summer?
In Saudi Arabia, air conditioners run for long hours in high ambient temperatures, placing immense strain on the compressor. Any minor malfunction in winter, such as a dirty coil or a weak fan, can escalate into a surge in operating pressure during the summer, potentially causing the air conditioner to shut down automatically or damage the compressor. Maintenance is easier in the spring because technicians are less busy than during the peak summer season.
Checklist: Indoor Unit
| Item | What are you checking? | Who does it? |
|---|---|---|
| Filters | Dust and blockages, clean with water and dry. | Homeowner |
| Cooling coil (evaporator) | Dust and mold on the fins | technical |
| Drainage tray and hose | Blockages, leaks, and odors | Technically speaking, you can see the leak. |
| internal fan | Dirt, vibration, and noise | technical |
| Remote and sensors | Batteries and response | Homeowner |
Checklist: Outdoor Unit
| Item | What are you checking? | Who does it? |
|---|---|---|
| Capacitor file | Dust, leaves, and curved fins, and wash it | technical |
| Unit perimeter | Remove obstacles and leave space for air movement. | Homeowner |
| Condenser fan and motor | Rotation, sound, and vibration | technical |
| Freon pressure | Pressure gauge reading compared to manufacturer's values | Technical only |
| Electrical connections and electrical capacitor | Limb relaxation, heat, and erosion | Technical only |
| Pipe insulation | Cracking and damage from the sun | technical |
What can you do yourself?
- Disconnect the electricity from the air conditioner before any work is done.
- Remove the filters, wash them with lukewarm water, and let them dry completely before putting them back in.
- Clean the front of the indoor unit with a damp cloth.
- Remove any obstacles or debris around the outdoor unit.
- Monitor the drainage: If you see water dripping inside the room, call a technician.
As for opening the units, washing the coils with chemicals, and checking the Freon and electricity, leave these to a specialized technician, because mistakes in them may damage the air conditioner or pose an electrical hazard.
Maintenance of central systems and package units
- Air ducts: Check for leaks, insulation, and cleanliness, especially at intake points.
- Air handling units: Filters, belts, bearings and fans.
- Chiller: Inspection of condensers, evaporators, pumps, water treatment and temperature sensors.
- Control systems: Thermostat calibration and operating schedules.
These systems require a specialized team and regular visits, and are often Maintenance and operation contracts This is the most suitable solution for her. The difference between the systems is explained in the article. Split, central, or package.
Signs that your air conditioner needs urgent maintenance
- The air coming out is not as cold as usual, or the air conditioner is running continuously without the temperature dropping.
- Ice formed on the pipes or internal coil.
- Unnatural noises or vibration in the outdoor unit.
- Water leaked into the room.
- If you smell burning or the circuit breaker frequently trips, immediately disconnect the air conditioner and call a technician.
- A sudden increase in the electricity bill without any change in usage.
How often should air conditioners be serviced?
Filters should be cleaned regularly during the operating season, and more frequently in dusty areas. Comprehensive maintenance by a technician is recommended at least once before summer for homes, and more often for buildings and air conditioners that run for extended periods. If an air conditioner runs continuously but fails to reach the desired temperature despite maintenance, its capacity may be insufficient for the room's heat load. In this case, a professional's calculation of the heat load is helpful.
Frequently Asked Questions
Is washing the filter sufficient for maintenance?
Washing the filter is important, but it does not replace cleaning the coils and checking the refrigerant, electricity, and drainage with a technician at least once before summer.
Does the air conditioner need to have Freon refilled every year?
No, the system is closed and not consuming refrigerant. If the refrigerant level is low, it means there is a leak that must be repaired before recharging.
Why is water dripping from the air conditioner inside the room?
Often due to a blockage in the drain hose or drain tray, or a tilt in the installation of the indoor unit.
Does maintenance actually save electricity?
Clean coils and filters make the air conditioner reach the required temperature faster and switch off in time, and this reduces the hours the compressor is running.
