How To Clean Mold Off Ac Unit

How To Clean Moldy Air Conditioner

Cleaning mold out of a window AC unit.

Depending on the severity of the mold, you can also try to remove it by removing the mold with a bleach solution. Its important to be careful when handling bleach because the solution can be toxic if you dont wear protective gear. Moreover, its also important to wear a mask, gloves, and goggles before you begin cleaning. This will ensure that you dont breathe in the mold spores.

Then, you should apply Tilex to the frame of the air filter. Then, you should add some antibacterial dish soap to the water. This will help to kill bacteria and other contaminants in the air. After youve applied the antibacterial soap, its time to remove the air filter. You should then apply the clean filter with the resulting solution and then clean it as well. After the mold has been removed, you should clean the ducts and leave the area until the problem is gone.

Scrub Inside Air Conditioner

Immerse your scrubber into the cleaning solution you made. Thoroughly scrub inside and around the AC unit.

Change the cleaning solution as needed. A thorough scrub should be able to remove the mold growth. However, if you notice that it is persistent, you are better off calling a professional to remove the mold from your AC.

Allow the cleaning solution to sit on your AC surface for approximately 10 minutes.

Should I Replace The Vents/ductwork

Just because the vents are moldy, theres no need to replace them. As long as structural integrity remains, simple cleaning is enough. If you have a central AC system and the vents are moldy, take a look at the ductwork. Finding mold here a well is not uncommon.

If mold exists within your ductwork, theres no need to worry about replacing that either.

In fact, with a flexible mop and the cleaning solution of your choice may be enough to deal with it. You should know that if the situation is bad enough, you can call professionals in for ductwork cleaning.

Air conditioners are essential to keeping your home and business cool during hot weather. Split air conditioners are a common type of cooling system well-known for their compact, ductless format. The inner unit looks like a long rectangle thats built into a wall of your home, while the outdoor unit, known as a condenser or compressor, looks like a large metal box. Any air conditioner is only as good as its inner workings, so its important to examine and clean your split A/C often. Start by accessing and cleaning your indoor A/C unit before you work your way outside to clean the condenser.

How To Prevent Window A/c Units From Molding

Mold appears as the result of a damp environment. If your window A/C unit has mold on it, that means you’re at risk for health problems and a costly replacement.

To fix this problem, Warner Service is offering some expert prevention tips:

Buy a unit with humidity control. Many window A/C units come with a humidity control option. This option allows the air conditioning unit to control the level of humidity in the air, automatically discouraging the growth of mold.

Use auto mode. When you leave for family vacation, dont turn your unit off. This leaves your home without airflow, causing moisture to build up without circulation and temperatures to rise without an active cooling system. Warm, moist, and stale air is the perfect environment for mold to grow.

Instead, use the auto function on your air conditioning unit. This will continuously cycle the air in your home while youre away for a long period of time.

Perform regular maintenance. HVAC maintenance is so important, especially during the shift in seasons. It allows your heating and cooling system to prepare for the change in weather before its too late.

Because window A/C units are dark and warm on the inside, it’s a great mold breeding ground. Preventing this requires basic HVAC maintenance, including checking it regularly and carefully cleaning any sign of water or formed mold.

    How To Get Rid Of Mold

    Despite regularly inspecting your system, you are still getting complaints about it , here are some tips you can share with your HVAC contractor for cleaning it up:

  • Turn off your HVAC system.
  • Everyone involved in this cleaning should wear at least an N-95 respirator
  • Replace anything porous, such as filters or insulation that has become wet. Double-bag the waste using 6-mil or thicker plastic bags.
  • Use wet vacuums to clean out any standing water.
  • Use an EPA registered disinfectant labeled for HVAC use to clean non-porous surfaces of mold, mildew, and other dirt. BIOSPRAY-TOWER ready-to-use disinfectant and mold cleaner will kill and remove mold, mildew, and odor-causing bacteria.
  • Clean the HVAC evaporator coils using a mechanical coil cleaning system to remove any solid debris.
  • As an added measure, isolate each section of ductwork you clean with bladders so the spores you stir up during cleaning dont spread to other parts of the system or the building. Fog the area with an EPA-registered disinfectant.
  • Apply a mold and mildew inhibitor to all components of the HVAC systems. Again, this must be EPA registered and specifically labeled for use in HVAC systems to limit risks associated with using the wrong chemicals and cleaners in HVAC systems. BBJ Mold Control is EPA registered for use in HVAC systems to control mold growth for up to 2 years.
  • As a final step, HEPA vacuum anything that you cleaned up.

    Remove Air Conditioner Components

    If you are cleaning the window air conditioner or working with individual vents of the air conditioners, use a screwdriver to remove the grille in front of the air conditioner.

    Next, unscrew the top and back of the cabinet and the front filter.

    As you unscrew, arrange them in an order that will help you have an easier time reassembling back. Put all the screws in one container you do not want to lose them.

    Cleaning Without Removing A Window Air Conditioner

    It can be hard to clean a window air conditioner without disconnecting it from the wall as you need a considerable amount of water. However, it is possible with a little more effort.

    Before starting the job, you should put some buckets under your AC. Then, take off the screws of the frontal case or mask and take out the filter.

    Afterward, you need to spray the device and wipe it with the dry cloth at the same time. Repeat the process until you see the frontal and inner parts are entirely clean. Dont forget to spray the filter and rinse it, as well. It is an excellent idea to do so in your bath or sink.

    The next step is to go outside and spray the AC without removing the cover. Do it wherever you see the hole. Leave the agent and water to soak all the parts of the device for approximately 15 minutes.

    Then rinse the device with water from the hose or bucket. Make sure not to pour a large amount of water immediately. It is better to use less water over a more extended period. While doing so, you will see the dirt comes from the bottom holes of the outside unit.

    You will know a window air conditioner is clean once the water coming out becomes clean. If needed, you can repeat the soaking part, but always rinse the detergent or bleach afterward.

    Once you have finished with the cleaning, you should leave all the parts to dry for at least 2 to 4 hours. After putting back all the pieces together, your seasonal cleaning is finished.

    Mold spores are literally all around us. They are constantly floating through the air and landing on sold surfaces. In nature, when those spores land on organic matter, such as fallen trees and leaves, they grow and feed on the matter, aiding in decomposition hence, outdoor mold growth is actually quite beneficial. Of course, mold spores get inside, too. The microscopic spores float inside through windows, doors, chimneys, and ventilation systems. They can also attach to shoes, clothing, bags, and anything else that goes outside, and when those items are brought back inside, they become airborne, travel throughout your house, and land on all types of surface.

    Try as you might, there is no way to completely eliminate mold spores in your house. Minimal concentrations of mold spores usually arent problematic the problem arises when those spores continue to multiple and become mold. Why? Because patches of mold release spores, and the concentrations of the spores that mold growth produces can be quite high.

Since it is impossible to stop mold spores from entering your house, in order to prevent the negative effects that mold exposure can cause, you need to work on preventing the spores from growing into the fungi.

    In order to grow, mold needs just a few basic things:

    With a tune-up, a certified technician inspects your entire system for any problems. Thats when we catch issues such as electrical problems or worn-out mechanical parts. Theyll also clean the system, avoiding problems like mold.

    How To Prevent Mold In The Air Conditioner

    Keeping mold out of your air conditioner is the best way to ensure you have clean air circulating in your home, and there are several steps to do this.

    HEPA filters: All air conditioner units come fitted with air filters. The problem with these filters is that they only block out the larger particles and they are there to protect the components of the unit and not your health. Fortunately, there are HEPA filters available for these systems, which will prevent microscopic mold spores from entering the air conditioner and, ultimately, your home.

    UV filters: Most new air conditioners available for purchase today comes with a bacteria-killing UV light filter already fitted. In many cases, a UV filter can be purchased separately and installed on the current AC unit. This filter kills up to 99% of all viruses, bacteria, and mold spores without putting any additional strain on your air conditioner.

    Yearly maintenance: Its recommended to have a professional come in annually to thoroughly clean and do maintenance on your air conditioner. Air filters and drain pans need to be cleaned and replaced, while air ducts should be cleaned and dried.
