5 Tips to Make Your AC Unit Work Efficiently

airconYou buy air conditioners to relax in the cool air, but the skyrocketing electricity bills don’t let you relax. However, you just have to see to it that your aircon is running efficiently and you can save money on the energy bills. Here are a few tips.

1. Choose the Correct Size of Your AC Unit

All AC units are designed for a specific amount of “air space”. Thus your unit may not work efficiently if your room is too small or too big and you may have to perform an aircon repair recurrently.

All window AC units have a BTU (British Thermal Unit) rating, usually in the range of 5,000 to 15,000. A rule of thumb is that every square foot of room space requires 20 BTU, along with 600 BTU for every person that occupies the room regularly. You may have to increase this by up to an extra 10% if the ceilings are high, a lot of sunlight enters the room etc.

However, ensure you don’t purchase a too big unit either. An oversized unit will continuously turn on and off since it’s too efficient at pumping out cool air, however, can’t dehumidify the room. Humidity can make a room seem much warmer than it really is.

2. Is Your Thermostat on the Right Wall?

Placement of thermostat can be very important in deciding how well your aircon works. If you place it on a wall just next to a hot window for instance, your aircon will start much more often than it’s required to because it will feel that the room is warmer than it really is.

3. Using a Fan

There are times when you don’t have to increase the thermostat to feel cooler. As per the NRDC (National Resource Defense Council), using a ceiling fan can make a room feel 10° cooler and uses 10% of the central aircon’s energy.

Today you can even get smart ceiling fans that are connected to an app. You can schedule the times when the fans should turn on and off, and their speeds can be controlled without having to move anywhere.

4. Keep the Windows and Doors Shut

An air conditioner pulls in hot air from the room, passes it over a refrigerant due to which heat is absorbed in the refrigerant and the AC blows the air thus cooled down back in the room expelling the absorbed heat out from the back of the unit.

Therefore window units are mounted in a closed window while central units are placed outside of the house. It’s necessary to isolate the ‘inside air’ and ‘outside air’ from each other for the AC to work efficiently. If you keep doors and windows open, the hot air expelled out is going to enter back in making your AC fail to work, eventually making aircon repair necessary.

5. Never Let the Cool Air Seep Out

If your home is old, the seal of your windows and doors may be worn out, your attic may be poorly insulated and there may be other sneaky cracks in the house. Make a home energy audit to check how well your home is holding the cold air in. Your home will be checked for leaks under such an audit and the auditor will suggest the best ways to make your house more energy efficient.

If you are not in a position to make such an audit, you on your own too can do it yourself. Go around your house and pass your hand over windows and doors. You may feel cool air escaping. If you find such leaks in windows, caulk around them and add insulation around doors.

Avoid common mistakes and you can make your AC work much more efficiently while cutting down on your energy bills. Happy air conditioning!
