    How to Clean Rheem Air Conditioner Internal Unit

    Inner block is the part of the Rheem air conditioner, which is located in the room. Its main parts are filter, fan, radiator and drainage system. On the walls of the inner block and inside its elements are collected a lot of dirt and dust.

    • Remove the lid. Remove the mesh filters, wash them. They should be vacuum cleaned and washed with warm water. If the filter is heavily soiled, you can soak it in water with any antibacterial agent.
    • After rinsing, the filter needs to be dried. The important point is that this cannot be done with a hot air stream, so it is better to simply wait until the filter has dried naturally.
    • Clean the heat exchanger from dust. It is a device of many small plates, which are located very close to each other. It can be cleaned with a powerful vacuum cleaner or with a long pile brush.
    • Clean the fan. You should spray it with soapy water and wait for about 15 minutes. After taking a regular toothbrush and thoroughly brushing the blades. Then remove the remaining dirt with a damp cloth and wait for the surfaces to dry.
    • Flush the drainage system. You can effectively clean the drain with the help of a steam generator. If there is no steam generator, you can blow the drain pipe with a vacuum cleaner or introduce a special liquid for cleaning Rheem air conditioners with a syringe.
    • When all the parts are dry, they should be installed in their place. In order not to make a mistake, I recommend to refer to the instructions.

    How to Clean Rheem Air Conditioner External Unit

    With the external unit, everything is not so simple. It is often installed in a way that makes it very difficult to access. I recommend entrusting the cleaning of the external unit to professionals, in addition, it should be cleaned less often than the internal unit – enough once a year, and it is better to do it in early summer, when the poplars will bloom. The only exception is the devices, which are installed on the first floors. They get dirty faster and should be cleaned three to four times a year.

    If the external unit is installed low, you can do a surface cleaning. First, disconnect the device from the mains, and then unscrew the cover mounts and remove it. After that, remove the large garbage with your hands and clean the parts with a brush or vacuum cleaner. There is no need to remove the parts. Finally, wipe all surfaces with a damp cloth and replace the cover. It is not possible to perform a deeper cleaning yourself.

    If you decide to clean the external unit yourself, be extremely careful not to touch the electrical circuit. Also, the Rheem air conditioner must not be turned on until it has completely dried out.

    In principle, there is nothing very difficult to clean the Rheem air conditioner with your own hands. It just needs to be performed regularly, carefully and at the same time, a little understanding of the air conditioner device. If you are very afraid of damaging any part of the device, it is better to call for the help of specialists.

      Your air duct system need to be cleaned for the same reason as your house needs cleaning. It is recommended that HVAC systems be cleaned every 3 years.
      Will air duct cleaning lead to lower energy bills?
      HVAC systems cleaning can improve air flow up to 25%. That means your system shouldn't be running as long as it's supposed to. Less system uptime will reduce your energy costs and will lead to lower your energy bills.
      Can dirty air ducts cause disease?
      In homes with dirty air ducts, residents may experience symptoms similar to those of an allergy, including coughing, sneezing, and runny nose. Mold, dust, and other debris lurking in your ducts can also cause sore throat, headaches, and even dizziness.
      How do you know if the ducts need cleaning?
      There are several clear indications that the duct needs cleaning:
      • air filters get dirty too fast.
      • unexplained spikes in your energy bill.

      • dirt or dust around the vents and registers.
      • unexplained respiratory problems.

      How often should I have my vents cleaned?
      A good rule of thumb for homeowners is to clean your ducts every three to five years.

However, some homeowners are going to need more frequent cleanings.
