Air conditioning units are essential for comfort during hot days, but require regular maintenance. A chemical overhaul is an effective way to restore peak performance, addressing common issues and ensuring effective cooling and improved indoor air quality.
What Is Included in a Chemical Overhaul?
A chemical overhaul is a comprehensive process that restores air conditioning units to their original performance levels, going beyond standard maintenance. Key steps in this service include:
Full Disassembly of the Indoor Unit
The fan coil unit is carefully removed from the wall, providing technicians with clear access to its components.
After this, covers, filters, and electrical parts are removed step-by-step to prevent any potential damage during the maintenance process.
Chemical Cleaning of Key Components
After disassembly,
Evaporator Coil: Dust, mold, and grease accumulation can reduce efficiency. Cleaning can enhance performance by up to 30% for better
cooling.
Blower Wheel (Fan Blower): A clean blower wheel enhances airflow and reduces noise levels. Dust accumulation can decrease airflow efficiency by around 25%, leading to higher energy usage.
Drain Pan and Drain Pipe: These parts are flushed out to remove algae and mold that can cause leaks and unpleasant odors.
Air Filters: Regularly cleaning these is crucial for maintaining proper airflow and good indoor air quality. Clogged filters can decrease airflow by about 15%.
Thermal Sensors and Circuit Boards: Technicians employ careful cleaning techniques that avoid harsh chemicals, protecting sensitive electronic components.
High-pressure water or specialized chemicals are often used to clear the fins and coils, improving heat exchange and overall efficiency by up to 25%.
Inspection and Testing
After cleaning, technicians thoroughly inspect the entire unit.
They check parts for wear, verify refrigerant levels, and listen for unusual sounds.
Once everything is put back together, the system is tested for overall performance to ensure it's functioning effectively before being reinstalled.
Chemicals Used
The cleaning agents used during a chemical overhaul are specifically chosen for their ability to break down grime and kill bacteria, all while being safe for various materials in the air conditioning unit.
Mild Acid- or Alkaline-Based Cleaners: These solutions effectively dissolve tough contaminants like dust, mold, and grease without damaging components.
Antibacterial Solutions: These solutions are essential in eliminating microbes that cause bad smells, helping ensure that your air conditioning unit not only performs well but also creates a healthier indoor environment.
Note: The chemicals selected are done so with care, balancing effectiveness with the safety of the various metals and plastics present in the air conditioning unit.
Why Is Chemical Overhaul Needed?
Understanding the process is crucial, but it's equally important to recognize when a chemical overhaul becomes necessary.
Poor Cooling Despite Filter Cleaning
If your air conditioning unit struggles to cool effectively even after regular filter maintenance, this suggests deeper issues within the unit.
Foul Smells or Moldy Odor
Bad odors can indicate mold growth within the unit that can compromise air quality and health. A chemical overhaul is effective at targeting and eliminating these sources.
Water Leaking from the Indoor Unit
Leaks can indicate clogged drainage pathways, disrupting system operation. A thorough flushing is often required to resolve this issue.
Increased Electricity Consumption
A sudden rise in your energy bills may point to inefficiencies in the air conditioning unit. A well-maintained system can operate up to 20% more efficiently, saving on monthly energy costs.
Unusual Noise from the Fan or Motor
Odd sounds from the unit may indicate issues. A thorough inspection during a chemical overhaul can identify and resolve these problems early.
Restoring Comfort and Efficiency
A chemical overhaul for air conditioning servicing represents a thorough method for restoring the unit's efficiency and effectiveness. With a focus on deep cleaning and careful inspection, this process can resolve vital issues, including poor cooling, bad odors, water leaks, and high energy bills. Investing in a chemical overhaul can extend your unit's lifespan and significantly enhance indoor air quality.
If you recognize any of the symptoms mentioned above, consider scheduling a chemical overhaul for your air conditioning system.
Regular maintenance saves money and ensures a comfortable, healthy indoor space for your family.
