How to eliminate cigarette smoke odors absorbed by an American Standard AC?

 
Safety Precautions
 

• Unplug the unit and ensure that the power is off before beginning any cleaning process.
• Wear protective gloves, a mask, and ensure proper ventilation in the area where you will work.
• Consult the American Standard AC manual for any specific safety instructions related to your model.

 
Clean Air Filters and Replace if Necessary
 

• Remove the air filters from the AC unit. Cigarette smoke particles can be trapped here, so cleaning or replacing them is essential, especially for residents in St. Louis.
• Wash reusable filters with warm, soapy water and allow them to dry completely, or replace disposable filters if they are heavily contaminated.
• Ensure that all dirt and debris are removed – this will help in reducing ongoing smoke odor absorption.

 
Deep Clean Interior Surfaces
 

• Carefully remove or open the service panels on your American Standard AC to access internal components like the evaporator coil and fan.
• Using a soft cloth or a vacuum with a brush attachment, gently remove accumulated dust and residue. Focus on areas exposed to smoke.
• Prepare a cleaning solution of warm water mixed with a mild detergent. Wipe down accessible hard surfaces such as fins and inner metal parts.
• For stubborn odors, consider using a solution of diluted white vinegar – its natural deodorizing properties can help neutralize cigarette smoke smells.

 
Clean the Evaporator Coil and Drain Lines
 

• The evaporator coil tends to absorb smoke particles. Use coil cleaner recommended by the manufacturer, following the instructions carefully, to break down residues.
• Flush the drain lines with a mixture of water and vinegar to eliminate odor-causing deposits that can circulate back into the system.
• Allow all parts to dry completely to prevent mold or mildew formation which can exacerbate odors.

 
Odor Neutralization and Absorption
 

• Place activated charcoal near the AC unit or inside the immediate area; charcoal is effective in absorbing lingering odors over time.
• Consider using odor neutralizing sprays or gels specifically designed for smoke; apply them around the external parts of the unit.
• If possible, run the AC system with a clean air filter and let fresh air circulate through the system to help clear out trapped odors.

 
Consider Professional Maintenance
 

• If the odor persists despite thorough cleaning, consult a professional HVAC technician who can perform a comprehensive servicing of your American Standard AC.
• Technicians may use specialized cleaning agents and equipment to remove deeply embedded smoke odors and ensure the unit operates efficiently.
• Regular professional maintenance can prevent the buildup of odors in the future and extend the lifespan of your unit.
• Homeowners and businesses in St. Louis can also benefit from swift local technical support.
