5 Tips to Keep Your portable Air Conditioning System in Shape and Reduce Energy Bills

Portable air conditioners use a lot of energy. By following these tips, you can keep your system in good shape and reduce your energy bills.

  1. Check the filter regularly. A dirty filter will cause your system to work harder to cool the room, which will lead to higher energy bills.
  2. Clean the unit regularly. Dust and debris can build up on the unit, which will also require more energy to cool the room. Clean it every three months or so to keep it running smoothly and efficiently.
  3. Use low-energy modes when possible. When you’re not using your portable AC, turn off the fan and compressor completely. This will help conserve energy and save you money on your energy bill.
  4. Check the air conditioner’s seals and hoses regularly. If they’re leaking, the system will work harder to cool the room, which will lead to higher energy bills.
  5. Use a programmable thermostat to save even more energy. A programmable thermostat can be set to turn off your system when it’s not in use, which will help conserve energy and save you money on your energy bill.
