Preparing your air conditioner before the season can reduce electricity consumption, extend the life of the device, and prevent that classic summer scenario: you're sweating and the repairman has his first free appointment in August.
When the temperature outside gets dangerously close to feeling like “Dubai city asphalt,” most people do the same thing: they reach for the remote, hit the cooling button, and hope for a cooling effect. air conditioning performed a miracle. But an air conditioner is not a magic box on the wall. If it has been collecting dust all winter, it will use more energy to cool the room, run louder, and wear out faster.
The good news? You can do much of the preparation yourself. Even better news? This can save you from higher bills and unnecessary visits to repairmen, who are about as sought after in the heat as shade on the beach.
1. Clean the filters first – the air conditioner does not breathe well through dust
Filters are the first line of defense for your air conditioner. Their job is to trap dust, hair, pollen, and other tiny particles that you don't want to breathe in. When filters are clogged, airflow is reduced, and the air conditioner has to work harder to achieve the same effect.
This means more power consumption, poorer cooling, and a greater strain on the device. In practice, this is like trying to run a marathon through a scarf. Romantic perhaps in winter, completely useless in July.
Remove filters before the season, clean them according to the manufacturer's instructions, and dry them thoroughly before returning them to the appliance. Some models can be rinsed with lukewarm water, while others require replacement. Regular cleaning or replacement of filters can reduce energy consumption by about 5 to 15 percent, which is noticeable during the summer.
2. Check the outdoor unit – it shouldn't live in a botanical garden
The outdoor unit needs to have enough space around it to effectively dissipate heat. If it is surrounded by leaves, twigs, dust, weeds or cobwebs, the air flow will be impaired. The result? The air conditioner will work harder, cool less effectively and use more energy.
Before the season, check that the outdoor unit is clean and unobstructed. There should be at least half a meter of free space around it. Remove leaves, twigs and other dirt. Be gentle when cleaning, as the fins are sensitive. A high-pressure cleaner is not a good idea unless you want to turn your air conditioning into an expensive experiment.
3. Inspect the cooling fins – a small thing, a big difference
The cooling fins on the indoor and outdoor units are responsible for heat exchange. If they are dirty, clogged or bent, the air conditioner cannot operate optimally. This means that it will take longer and use more electricity to reach the set temperature.
You can visually check the outside unit to see if the fins are full of dust or pollen. If they are very dirty or damaged, it is better to call a repairman. Home “repairs” with a screwdriver and good intentions can quickly end up with a bill that will not be exactly wellness for your budget.
4. Check the pipe insulation – keep the cooling where you need it
The indoor and outdoor units are connected by pipes through which the refrigerant circulates. These pipes must be well insulated. If the insulation is cracked, weathered or falling off, energy is lost where it is not needed. In other words: the air conditioner is cooling something that is not your living space. And unless you have an aesthetic need to cool the facade, this is a pure waste of energy.
Before the season, check to see if the insulation on the pipes is still intact. Minor damage should be repaired by a professional or repaired with appropriate insulation material if you know what you are doing. For major damage, a service is a smarter decision.
5. Don't forget the condensation drain
During cooling, the air conditioner removes moisture from the air, which needs to drain somewhere. If the condensate drain is clogged, water may start dripping from the indoor unit, an unpleasant odor may appear, or even moisture may appear on the walls.
Before the season starts, check that the condensation is draining properly. If you notice dripping, a musty smell or damp spots, take action quickly. Water and electrical appliances are not exactly a dream match.
6. Call a repairman before everyone needs one
Some tasks can be done by yourself, but for others it's better to admit that a YouTube diploma in air conditioning service is not always enough. A professional inspection is recommended at least every two years, and with intensive use, every year.
The service technician checks the pressure or amount of refrigerant, the operation of the compressor, the tightness of the system, the electrical connections, the condensate drain and the general condition of the device. Too little or too much refrigerant can greatly reduce efficiency, increase consumption and, in extreme cases, damage the compressor. This is the part of the air conditioning that makes your wallet sweat.
The best time to get serviced? Before a heat wave. When the first real summer heat hits, service technicians are often busy, while you're practicing tropical survival in your living room.
7. Set the temperature wisely – 18°C is not a life goal
Once the air conditioner is cleaned and prepared, the next step is to use it properly. The biggest mistake is setting the temperature too low. If it's sweltering 34°C outside, an indoor temperature of 18°C is not a luxury, but an energy self-sabotage project.
The recommended room temperature is between 24 °C and 26 °C. The difference between the outside and inside temperature should preferably not exceed 6 to 8 °C. Every degree lower means higher energy consumption, often by around 5 to 8 percent.
Besides, too much temperature difference is not pleasant for the body. You know: sauna outside, cold room inside, and then we wonder why our nose is protesting.
How to use less electricity for cooling in the summer?
First, prevent the room from getting too hot in the first place. During the day, lower the blinds, shutters, or curtains on the sunny side of the apartment. The sun through the glass heats the room very quickly., and the air conditioner then repairs the damage that could have been prevented with one pull of the blinds.
Don't turn off your air conditioner every 15 minutes you're away. If you're leaving the room for a short time, turn it up a degree or two. Turning it on and off frequently can put more strain on the system.
Also use the dehumidification or “Dry” function. Sometimes it’s not just the heat that’s the problem, it’s the humidity. When the air is less humid, the room feels more comfortable even at a slightly higher temperature. The dehumidification function often uses less energy than intensive cooling.
And a classic: close the windows and doors when the air conditioner is running. An air conditioner that cools a room with an open window is about as effective as a diet plan with nightly visits to the refrigerator.
Conclusion: Air conditioning should cool the room, not your bank account
Before the summer season begins, take some time to do a basic inspection of your air conditioner. Clean the filters, check the outdoor unit, remove obstructions, inspect the pipe insulation, and make sure that condensation is draining properly. If your unit hasn't been serviced in a while, schedule a professional inspection before the summer panic begins.
A properly maintained air conditioner runs quieter, more efficiently, and more economically. It's also less likely to break down on the very day your apartment turns into a slow oven.
Summer is better when your home is pleasantly cool. And it's even better when you don't get a bill that requires additional cooling.
