Spray alkaline coil cleaner over the fins and coils. Be sure to read the manufacturers instructions on how to do this safely. Let the cleaner set and drip for the time specified in the manufacturer's directions. Spray off the cleaner with water in a spray bottle.
Use an EPA-registered disinfectant labeled for HVAC use to clean non-porous surfaces (Ductwork, coils, plenums, pans, etc) 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.
Yes, bleach will cause health issues if used frequently on an evaporator coil. It's very caustic and very bad for a person to be in contact with or inhaling in any way. It will also damage your coil. The chemicals we use are tested to make sure they will not eat a coil and cause leaks.
While there are a number of commercially available coil cleaning solutions on the market, air conditioner coils can be cleaned with a solution of a mild household detergent and water. The detergent and water mix is applied to the coil using a low-pressure sprayer.
Fill a plastic bucket with a few gallons of hot water and about 1/2 cup of household bleach. Saturate a scrubbing sponge in the bleach solution and use it to wipe the inside surfaces of the ac replacement unit, removing all traces of visible mold. The bleach will kill residual mold spores.
Stachybotrys Chartarum (Black Mould)
It produces mycotoxins, which can be toxic when inhaled or touched. Exposure to Stachybotrys chartarum can lead to respiratory problems, headaches, and skin irritation.
Turn off the power to your air conditioner. Locate the evaporator coils, which are typically found inside the indoor unit or air handler. Carefully remove the access panel or cover to expose the coils. Use a vacuum cleaner with a soft brush attachment to remove dust and debris from the coils gently.
You could also use a homemade mix of water and mild detergent (like dish soap) instead of commercial chemical cleaners. After cleaning the coils, it's also a good time to inspect the other parts of the unit. Inspect the condensate drain pan and remove anything that doesn't belong there.
Most HVAC professionals recommend AC coil cleaning once or twice a year. If dust and dirt build up on the coils, major problems can occur. The AC coil cleaning cost is around $100 to $400 as of 2024, according to Homeguide (for an evaporator coil), and up to $700 to remove and clean the coil.
Yes, vinegar mixed with water is often used to perform DIY cleaning on AC coils at home. However, vinegar is usually effective only against lighter dirt build-ups. Nevertheless, you can keep your coils in good shape by mixing white vinegar and water in a spray bottle and spraying the mixture onto the coils.
There are specific cleaning solutions that remove dirt and grime from evaporator coils or condenser coils. Read the label before starting to ensure you're using the right solution. Avoid using acid-based cleaners indoors, and never mix different brands of cleaners.
Cleaning AC Drain Line
We recommend using vinegar instead of a bleach solution because bleach can cause corrosion if you have copper tubing in your AC's drain line. In addition, spilling bleach can ruin your carpet or clothing, whereas vinegar does not harm; it just leaves an odor.
While Dawn dish soap is a versatile cleaning agent, it's not recommended for cleaning AC coils due to its chemical composition.
The cost to remove mold from an HVAC system is $2,000 to $10,000, depending on the system type and whether the mold has spread into the ductwork.
Keep Up With Air Filter Changes
In fact, a clogged air filter can actually harbor mold growth, especially if the filter is exposed to moisture due to a leak or excessive humidity. To prevent mold from circulating throughout your air conditioner, you should replace your air filter on a regular basis.
You're probably wondering if you can clean your AC coils by yourself. The answer is yes! Cleaning your air conditioner coils is a fairly simple and inexpensive project that you can do yourself, but it's important to do it carefully so that you don't damage your AC unit.
Spray the coils down with Simple Green All-Purpose Cleaner.
Let the Simple Green sit 10-15 minutes to penetrate heavier soils, and then hose it down again. After the coil cleaner has dripped off the coils, examine the coil surfaces for any areas that may need another application, and repeat this step as necessary.
If you feel oil while touching the coils, you can try another solution. Likewise, you can create a mixture of water, vinegar, and a spoonful of baking soda or use a mild dishwasher or washing powder for more effective and thorough cleaning.
Potassium or sodium hydroxide are widely used as active ingredients in coil cleaners.
Simply mix one cup of white vinegar with a gallon of warm water and spray the solution on the mold. Give the solution time to work its magic (about an hour) and brush the remnants out of your air conditioner. However, since mold is toxic, you must wear protective gear while cleaning the mold out of your AC unit.
The good news is that you absolutely can spray water on your air conditioner if it needs a cleaning, and nothing bad will happen. Spraying water on your AC's condenser also helps it run more efficiently. In fact, your condenser needs a regular spritzing in order to keep doing a good job.
