Is Frequent Ductless Mini-Split Cleaning Essential?

Ductless mini-split systems have become popular in recent years for their energy efficiency. Unlike other systems that use fuel and electric energy to heat or cool a room, mini-split systems transfer warmth to provide cooling or heating. While your HVAC technician will clean your system during routine maintenance, it may not be enough. You need comprehensive cleaning for complete dirt removal.

Cleaning the Indoor Unit

Our HVAC technicians will remove the system’s front panel to access the mini-split filter. They will then clean it with a mild detergent solution and air-dry it before replacing it. The evaporator coils contain the refrigerant that’s responsible for heat transfer. The coils may accumulate dirt which restricts proper heat transfer. It should be handled with care to prevent breaking and leakage. Our technicians will remove the unit’s cabinet to access the coil and then remove dirt, mold and grime using a clean, dry cloth and a coil cleaner. Indoor unit cleaning is concluded by removing dirt on the condensate drain with bleach or soapy water.

Cleaning the Outdoor Unit

The outdoor unit is prone to accumulating debris, including twigs and leaves. Grass and weeds may also grow around the unit and pests may build nests inside. Remove all the large dirt materials and ensure at least 2 feet of clear area around the unit. Our technicians typically use a garden hose to clean the exterior surface and a cloth to remove stubborn dirt and grime on the unit housing. They will also scrub the grille and fan cage with a cleaning brush. The fan blades are delicate and are carefully wiped with a damp cloth to avoid bending or damaging them. To prevent rusting, they ensure the blades are completely dried with a dry cloth.

Why You Should Regularly Clean Your System

There are several benefits of keeping your mini-split system clean. Here are five reasons you should regularly clean your system.

1. Improved Air Quality

One primary reason to prioritize regular cleaning of your ductless mini-split system is to maintain good indoor air quality. Airborne pollutants can accumulate on the filters and in the unit, leading to reduced airflow. The contaminants can trigger health complications including allergies, asthma and other respiratory issues.

2. Efficient Operation

A clean, ductless mini-split system operates more efficiently than a dirty one. When dust and debris clog the filters and coils, the unit has to work harder to maintain the desired temperature. This leads to increased energy consumption and reduced cooling or heating capacity. By keeping your mini-split system clean, you can save on energy bills and enjoy optimal indoor comfort.

3. Prevent Mold and Mildew Growth

Moisture buildup within a ductless mini-split system can create a conducive environment for mold and mildew growth. These fungi emit unpleasant odors and pose health risks, especially to people with allergies or weakened immune systems. Regularly cleaning the coils and drainage systems helps prevent moisture accumulation and the subsequent growth of mold and mildew.

4. Longer System Life

Investing in regular cleaning can significantly extend the lifespan of your ductless mini-split system. Dirt can strain the unit’s components, leading to premature wear and tear. This can lead to issues including compressor failure, bent fan blades and dented casing, which can accumulate and lead to system breakdown. A well-maintained unit is less likely to experience unexpected breakdowns and premature replacements.

5. Cost Savings

You can avoid costly repairs and early replacement by catching potential problems early through regular maintenance and cleaning. Additionally, a clean system operates more efficiently, resulting in lower monthly energy bills. Even though there may be a high cost for regular professional cleaning and maintenance, the long-term savings may outweigh the initial investment.

Cleaning Frequency

The cleaning frequency for your ductless mini-split system depends on various factors, including usage, environment and the presence of pets or high dust levels. We recommend that you conduct basic cleaning every two to four weeks. Schedule professional maintenance at least once a year for a deep cleaning. If you live in an area with high pollution or have family members with allergies, you may need to clean your system more frequently.
