Welcome aboard!  Here, you will find some simple steps to help maintain a high quality living environment in your home by minimizing the potential for mold growth that could occur naturally over a period of time.  You will also benefit from associating yourself with your air conditioning unit by doing some simple preventive maintenance.  The best way to treat indoor air is by circulating the air through a ventilation system (an air conditioner or some other mechanical means) that have a central core that could change the air physical parameters.  As you will observe, these steps will also be effective for treating your office, cars, or any leisure vehicles that have air conditioning systems.

    1.  To help minimize mold growth in your home, do the followings:

 

A.          Clean and dust your place on a regular basis.  Regularly vacuum, mop, and use environmentally safe household cleaners to help remove dirt and debris that contribute to mold growth.

B.           Periodically clean and dry the walls and floors around the sink, bathtub, shower, toilets, windows, and entrance doors using a common household disinfectant cleaner.

C.           Wipe down and dry countertops, windows, and windowsills where moisture sometimes accumulates.

D.          Thoroughly dry any spills on carpeting.

E.           Do not overfill closets or storage areas.  Ventilation is important in these spaces.

F.           Do not allow damp or moist stacks of clothes or other cloth materials to lie in piles for an extensive period of time.

G.          Repair any water leaks immediately.

H.          Get professional cleaning service to remove existing mold that cannot be removed by simply applying a common household cleaner and wiping the area.

I.           Repair any inoperable windows or doors to help keep moisture out of the area.

J.          Locate any musty odors in the area and clean with disinfectant.

K.           Proper ventilation is essential. Open windows or run the fan from the air-handling unit to circulate fresh air throughout the rooms.  Do not open windows or doors during damp, rainy, pollen season, or dusty conditions.

L.           Maintain the temperature in the house between 60° and 80° Fahrenheit. Relative humidity should be between 35% and 65%.

M.         Use exhaust ventilation fan when bathing or showering and allow fan to run until all excessive moisture has been vented from the bathroom.  Open the bathroom window if you do not have an exhaust ventilation fan.  Keep the bathroom air under negative pressure when in use and by making sure that air travel outside through the exhaust fan.  Reduce the air supply register to create a negative pressure with the bathroom door close and the exhaust fan running.

 

2.  To help reduce bacteria in your air-handling unit, do the followings:

 

A.      Turn off the air conditioning unit.

B.       Replace air filter on a regular basis. Quarterly or semi-annually.

C.       Keep the cooling coil clean by washing the tube or fin surfaces down with a sponge, warm water, and anti bacteria detergent.  Wipe off any excessive water with a clean cloth.  Do this process only if the cooling coil is accessible and during cooling season.  Recommend cleaning the cooling coil only when the coil is dirty or every five years with proper preventive maintenance.

D.      Keep the condensate water drip pan clean by removing any debris and by making sure water flows freely through the water drainage pipe.

E.       Get professional duct cleaning service to clean the air duct if you have not clean the air duct in more than 15 years.  Dirty air duct is one of the main causes for circulating and spreading all sorts of viruses throughout the house.

F.       Once all equipment parts are clean and ready to run, reassemble the air-handling unit.

G.      Turn the fan on and the system in the cool mode.

H.      Spray a can of Lysol anti-bacteria mist with disinfectant near the return duct register in circular motion while the air-handling unit is operating.  Continue to spray for approximately 1 to 3 minutes or until the entire house smells like Lysol.  Wipe off excessive fluid around the return duct register with a clean cloth. (The alternative way to disinfect your air conditioning system is to have a professional duct cleaner sanitize your air-handling unit).

I.       Once the indoor air is cleaned and disinfected, set the thermostat on auto mode.

J.      Once your air conditioning system is running properly, you could place a room air freshener near the return duct register.  Make sure that the room air freshener can be reached and replaced easily when it is time for a replacement.  Adjust the air freshener cap opening in small increment or until the air fragrance in the house is barely scented.  This option will keep your indoor air smells clean and fresh while the air-handling unit is operating!

 

     3.  To help keep the temperature evenly throughout the house, do the followings:

 

A.      Replace air filter in the air-handling unit.

B.       Install a room thermometer in each room to help read the actual temperature of the room.

C.       Make sure that air can travel easily from the supply register in each room to the return register without any obstructions.  Stagnated air tends to cause the air-handling unit to run inefficiently and shorten the life of the air conditioning system.

D.      Determine the room with the highest temperature when heating the house.  Remember that heat travel from hot condition to cold condition. For example, in the winter season, indoor hot air tends to escape from the house leaving the house cold.  However, in the summer season, outside hot air tends to intrude into the house adding heat to the house when the house is being cooled. The bottom line is “Keep the entrance door and windows shut while cooling or heating the house”.

E.       If there is a damper control install in the room air register, reduce the airflow gradually until the temperature reads about the same as the main house thermostat reading.  This process should take about 10 minutes or longer for each room temperature to stabilize.  Continue the process until all the rooms read about the same temperature.

 

 

     My intention in this webpage is to provide a simple method in keeping the indoor air clean and to control the growth of mold that could cause people to become sick and the potential of mold that could cause damage to your property.  If you have any additional tips or suggestions on how to keep indoor air clean or have any questions, please feel free to send me an email.  I am always looking for better ways to clean indoor air.  I will be adding more tips to this website in the future.  Thank you for stopping by my webpage.
