As the summer heat grows, your split air conditioner becomes your best friend. They provide a cool place in the scorching heat. However, regular cleaning and upkeep are important to keep them working and maintain the air quality. Moreover, cleaning a split air conditioner might seem like a difficult task. But with the right tools and a bit of patience, you can do it like a pro. Today, we will walk you through the steps to clean your home tank chillers. Thus ensuring they work at their peak while increasing their lifespan.

Do I Own A Split Air Conditioner? 65

Split air conditioners are the most common ACs out there. Moreover, you likely own a split AC if it cools a single room of your home.

Both an inside unit and an outside unit make up this sort of air conditioner. The indoor unit is a long, narrow rectangular box that attaches to the wall. However, the exterior unit, often known as a compressor, resembles a big metal box. Also, split AC units use pipes to link the outdoor unit to the internal unit. Fortunately, split air conditioners are simple to clean because of their design!

How Often My Air Conditioner Requires Cleaning? 63

Typically, you should clean your air conditioner at least twice a year. However, the amount of time you use your air conditioner determines how often you should clean the filters. So, clean your AC filters more frequently when using them quite often. Moreover, it makes sense to clean the filters in the spring. This ensures your air conditioner is ready for summer beforehand. It will allow you to enjoy a cleaner system when in use.

Why Is It Important to Cleaning Split ACs?

Before diving into the cleaning process, you should know why cleaning your split AC is important. Although, neglecting regular maintenance can lead to several problems, including:

Reduced Efficiency

Dust and dirt can build up. Especially on the evaporator and condenser coils. Thus reducing the system’s working and increasing the energy use.

Poor Air Quality

A dirty air conditioner can cause allergens and other pollutants to build up. This risks indoor air quality and causes health issues.

Breakdowns

Dust buildup can put a load on the system. Thus leading to breakdowns and costly repairs.

Shortened Lifespan

If you don’t pay attention to your AC, it can suffer from wear and tear. Thus shortening its lifespan.

Now that you understand the importance of cleaning your split AC. Let’s delve into the step-by-step process of cleaning it professionally.

Tools and Materials You Will Need

Before you dig into your AC, you’ll need some tools:

  1. Screwdriver
  2. Fin comb
  3. Vacuum cleaner with a nozzle attachment
  4. Brush with soft bristles
  5. Water hose with a spray nozzle
  6. Coil cleaner or a mixture of mild detergent and water
  7. Towels or rags
  8. Plastic bags or covers for electronic components

Step 1: Turn Off the Power

Safety should always be your top priority. So, start by turning off the power supply to the air conditioner at the main circuit breaker. This prevents any accidents while you are working on the unit.

Step 2: Remove the Outer Cover

Most split air conditioners have an outer cover that protects the inner parts from dust and dirt. Hence, use a screwdriver to remove the screws of the cover and set it aside.

Step 3: Clean the Filters

Remove the filters and wash them with a mix of mild detergent and water. Use a soft brush to clean off the dirt and debris gently. Lastly, rinse the filters well with clean water and allow them to dry before reinstalling them.

Step 4: Clean the Evaporator Coils

Evaporator coils are responsible for cooling the air. Dust can cover them over time, reducing efficiency. Moreover, use a fin comb to straighten any bent fins on the coils. Then, use a vacuum cleaner to remove loose dirt. Be gentle to avoid damage.

Step 5: Clean the Condenser Coils

The outdoor unit has condenser coils, making them completely open. Thus, leaves and dirt can clog them. First, use a brush to clean the surface of the coils. Then, remove any dirt from the surrounding area. This ensures proper airflow to the unit.

Step 6: Clean the Drainage System

A clogged drainage system can lead to water leakage and mold growth. So, inspect the drainage pipes and clear any blockages using a pipe cleaner or a wire. Ensure free water flow from the indoor unit to the outside.

Step 7: Clean the Fan Blades

Dust can cover fan blades in both the indoor and outdoor units. Gently clean the blades with a damp cloth or sponge. Ensure the blades are dry before reassembling.

Step 8: Reassemble the Unit

Carefully put the outer cover back in place and secure with the screws. Make sure it fits snugly to protect the inner unit from dust.

Step 9: Test the Air Conditioner

Turn the power supply on at the main circuit and test your air conditioner. This helps you know if it’s working well. Check for any unusual issues with cooling performance.

Step 10: Regular Maintenance Schedule

Cleaning your split AC like a professional is not a one-time task. For best performance and long lifespan, follow a regular maintenance schedule. Here are some tips:

  • Clean the filters every two weeks during peak usage months and once a month during the rest of the year.
  • Schedule deep cleaning for the coils and drainage system. Do it at least yearly and before the summer season begins.
  • Keep the area around the outdoor unit clean of any vegetation.
  • Invest in professional inspection every 2-3 years to address any serious issues.
