Heat Pump Cleaning: Why is It Necessary and What Happens if You Don't Clean Your Heat Pump?

Posted on May 27, 2024

As a homeowner in Christchurch, maintaining your heat pump regularly is crucial. Not only does it ensure the longevity of your appliance, but it also enhances its efficiency, saving you money on energy bills. This comprehensive guide will dive into the necessity of heat pump cleaning, explore the consequences of neglect, and provide actionable tips for keeping your heat pump in optimal condition.

Why is Heat Pump Cleaning Necessary?

1. Improves Energy Efficiency

A clean heat pump operates more efficiently, consuming less energy to maintain the desired indoor temperature. Dust and debris can clog the filters, obstructing airflow and forcing the system to work harder. Regular cleaning ensures that the heat pump functions smoothly, reducing energy consumption and lowering your utility bills.

2. Enhances Air Quality

A well-maintained heat pump filters out dust, allergens, and other pollutants from the air. When the filters are clogged, these contaminants can circulate throughout your home, leading to poor indoor air quality and potential health issues. Regular heat pump cleaning helps maintain a healthier living environment.

3. Extends the Lifespan of the Heat Pump

Routine maintenance and cleaning can significantly extend the lifespan of your heat pump. By preventing the buildup of dirt and dust, you minimise wear and tear on the components, ensuring that the system operates efficiently for longer periods.

4. Prevents Costly Repairs

Neglecting regular cleaning can lead to more significant issues down the line, requiring expensive repairs or even a complete replacement of the system. By investing time in routine maintenance, you can prevent minor problems from escalating into major ones.

What Happens if You Don't Clean Your Heat Pump?

1. Decreased Efficiency

Without regular cleaning, dust and debris accumulate in various parts of the heat pump, such as the filters, coils, and fins. This buildup restricts airflow, reducing the system's efficiency. As a result, your heat pump will need to work harder, consuming more energy to achieve the same level of heating or cooling.

2. Poor Air Quality

Clogged filters and dirty components can lead to poor indoor air quality. Dust, allergens, and other pollutants can circulate throughout your home, causing respiratory issues and allergies. Regular cleaning ensures that your heat pump continues to filter out these contaminants effectively.

3. Higher Energy Bills

When your heat pump operates inefficiently, it consumes more energy to maintain the desired temperature. This increased energy consumption directly translates to higher utility bills. Regular cleaning helps keep your energy costs in check by ensuring that the system runs optimally.

4. Increased Wear and Tear

Dust and debris can cause the components of your heat pump to wear out faster. Over time, this increased wear and tear can lead to more frequent breakdowns and costly repairs. Regular cleaning helps maintain the condition of the system, reducing the risk of unexpected failures.

How to Clean Your Heat Pump

How to Clean Your Heat Pump: A Step-by-Step Guide

Cleaning the Front Panel

  1. Lift the front panel until you hear a distinct “click,” indicating the panel is properly elevated and ready for removal.
  2. Hold both hinges firmly and gently pull to detach the panel from its frame. This ensures that the panel comes off smoothly without causing any damage.
  3. Wipe the panel thoroughly with a soft, dry cloth to remove any dust or dirt. Alternatively, you can rinse it with water, but make sure not to soak it in water for more than two hours and avoid using water hotter than 50°C to prevent any warping or damage.
  4. Dry the front panel completely with a soft, dry cloth to avoid any moisture buildup, which can lead to mildew or mould.
  5. Refit the front panel by aligning it properly with the hinges and pressing it back into place until it clicks securely.

Cleaning the Air Filter

Clean every seasonal change to maintain optimal airflow and efficiency:

  1. Open the front panel to gain access to the air filter. This usually involves lifting or unlatching the front cover of the unit.
  2. Remove the air filter carefully to avoid damaging it. This will expose the heat exchanger behind it, which also needs periodic cleaning.
  3. Remove dirt and debris from the air filters using a small brush to gently sweep away dust. For a deeper clean, you can rinse the filters with water that is no hotter than 50°C.
  4. Dry the air filter thoroughly with a soft, dry cloth or let it air dry in the shade to ensure no moisture remains, which could lead to mould growth.

Cleaning the Heat Exchanger

  1. If the heat pump has been cooling recently, it may be damp from condensation. Ensure the unit has been turned off for at least five hours before starting the cleaning process to allow it to dry.
  2. Avoid touching the heat exchanger directly with bare hands; instead, wear gloves to protect yourself from sharp edges and prevent injury.
  3. Clean the heat exchanger using a large brush, moving it vertically, up and down the fins to effectively remove any accumulated dust and debris.
  4. Use a smaller brush for precision cleaning, especially in hard-to-reach areas like the top and bottom of the heat exchanger, where dirt tends to accumulate more.

Cleaning the Air Cleaning Filter

Every three months:

  1. Remove dirt from the air cleaning filter using a vacuum cleaner. This helps to quickly remove surface dust and particles.
  2. If vacuuming is not enough to clean the filter, soak both the filter and its frame in lukewarm water and then gently wash and rinse them to remove any embedded dirt.
  3. Dry the air cleaning filter thoroughly with a soft, dry cloth or let it air dry in the shade to ensure no moisture is left, which can cause mould growth.
  4. Reinstall the filter by clicking it back into place ensuring it is securely fitted for optimal performance.

Every year:

  • Replace the air cleaning filter to maintain the highest efficiency and air quality. Refer to your specific product manual for detailed instructions on how to properly replace the filter and dispose of the old one. Regular replacement ensures that your unit continues to function effectively and maintains healthy air quality in your environment.

Cleaning the Fan

For Mitsubishi Electric models with a Quick Clean Body:

  1. Turn the horizontal vanes downward. To remove, unlock by sliding both tabs to the right.
  2. Swing out the vertical vanes one by one and clean the air outlet with a soft dry cloth.
  3. Clean the fan horizontally by moving a brush along the blades.
  4. Reinstall the vertical vanes into their respective guides until they click into place.
  5. Follow the removal procedure in reverse to install the horizontal vane.

For other models, consult your instruction manual for specific cleaning instructions.
