Year after year, the price we pay for energy goes up, so it’s important to keep control of the performance of air conditioning devices to avoid crazy bills. It is easy to test the efficiency of your air conditioner. Just one simple trick: turn on the unit for at least fifteen minutes when the outside temperature exceeds 26.5 degrees.
Then, using a precision thermometer, measure the temperature difference in the flow emanating from the supply ducts closest to the unit and the air entering the return ducts. The temperature difference must be a dozen degrees.
If you think your AC unit isn’t as efficient as you’d like, test some of the following steps to get your machine to higher performance.
- First of all, check that your computer is working properly. Notify the service technicians to perform an inspection of your unit. A professional can check coolant levels, clean coils, and filters, and check airflow over cooling coils, supply aircon refrigeration spares; these elements that can reduce your unit’s efficiency by up to 40%.
- If your computer runs smoothly, change or clean the filters once a month. Dirty filters accumulate lint that restricts airflow, so your air conditioners work hard to circulate the air.
- Monitor your equipment and remove any obstructions or debris from your device. Check that the space around the unit is kept clear so the unit can effectively inject air into your system.
- Make sure your fan is more than 60 centimetres from the unit. Dirt on the fan adheres to condensation batteries and maybe one of the reasons your equipment is losing it’s cooling or heat efficiency.
- Clean the coils of your air conditioner. Coils with bonded dirt can reduce the performance of your air conditioner by up to 10%. Be sure to review the manufacturer’s recommendations before performing any cleaning work. Many units can be cleaned with warm water and soap and a pressure garden hose. If necessary, use a toothbrush. Always turn off the power before cleaning the unit and be careful not to damage the delicate coils.
- Identify the flattened battery fins if you think they may be blocking the airflow. To straighten the fins, you can purchase a fin comb at any air conditioning facility.
- Review your outdoor air conditioning unit. A small cover that protects the drawer from the sun will make cooling the air easier and could gain up to 10% energy efficiency.
- Check that the pipe insulator is in good condition. The ducts can be sealed with putty tape or sealant and then can be wrapped at a very low price with fiberglass materials, for example. Although investment in improving duct insulation involves an outlay, this small improvement is amortized in less than three years with energy savings.
- Perform a visual inspection of your pipelines. Obstructions in the ducts are almost as harmful as leaks when it comes to reducing energy efficiency. Dirty ducts can also clog your machine’s evaporator coils, further reducing the effectiveness of an air conditioner.
- Do not block the air outlet parts. This involves keeping furniture and curtains away from these areas, as well as vacuuming them regularly.
- If you plan to leave the room for a long time, turn up the heat to maintain an optimal environment without recharging. Each grade that raises the thermostat in the summer can reduce your energy bill by up to 9%.
- Keep the unit fan set to automatic mode. This way, the fan will not need to run continuously. This will save the machine effort when you are not present.
- Use ceiling fans to keep the air moving and circulate the air, cold or hot, all over the house. You will get a pleasant and uniform atmosphere without the need to subject your equipment to too high or too low temperatures.
- Install a fan that transports air from your machine to the entire house. A fan that services the whole surface will allow you to expel hot air so that, once your machine is turned on, you can achieve the environment you want in much less time. This tip can allow you to reduce the indoor temperature by up to ten degrees in just a few minutes.
- Check that your space is well ventilated and that there are also no leaks in doors and windows. A poorly ventilated or leaky room can increase your cooling costs by up to 10%. It is important to check the holes d around the pipes, wiring, doors, and also windows.
- Use blinds or curtains to shade any part of the house that the sun can give intensely during the day. You can opt for screens that retain street heat, which have a special fabric that blocks sunlight without the need to cover windows.
- While not strictly part of the solutions that have to do with your air conditioner, remember to turn off the lights when they don’t need to be on and make the most of natural sunlight for your everyday tasks.
- To maintain a pleasant environment, try not to use appliances that release a lot of heat, such as the oven, dishwasher, washing machine or tumble dryer. And refrain, above all, from doing it late at night. This would force you to lower the temperature of your thermostat to balance hot emissions, so you would use more energy than necessary.
- Use a dehumidifier to reduce the level of humidity in rooms you will be in for long hours and avoid condensation and sudden temperature changes.
- Finally, do not forget to check all the rooms in your home to detect anomalies in the proper functioning of the appliances. The malfunction of electrical appliances accounts for approximately 30% of the costs of a house’s electricity bill.
