Mini Split Maintenance: A Comprehensive Guide for Homeowners

Mini split systems, also called ductless mini splits, are an efficient and popular way to heat or cool your home or specific areas within it. These systems provide targeted comfort without the need for extensive ductwork, making them ideal for homes, apartments, or spaces where traditional HVAC systems might not work.

However, like any HVAC system, mini splits require regular maintenance to perform reliably and last longer. In this blog, we’ll explore the importance of mini split maintenance, how often it should be done, what’s involved, and the costs associated with keeping your system in top shape.

How Often Does a Mini Split Need Maintenance?

While mini split systems are generally low maintenance compared to traditional HVAC systems, they still require periodic care to run efficiently. For most homeowners, it’s recommended to have professional mini split service performed twice a year, ideally before the heating and cooling seasons. This annual service ensures that your system is running smoothly and helps address any potential issues before they become costly repairs.

In addition to professional maintenance, there are some simple tasks that you can do throughout the year to keep your ductless system in good working condition.

The Benefits of Regular Ductless Mini Split Maintenance

Regular mini split maintenance comes with several benefits:

Improved Efficiency

Just like any HVAC system, a well-maintained ductless system works more efficiently. Regular upkeep, such as replacing filters, cleaning coils, and checking refrigerant levels, reduces energy consumption and lowers your utility bills.

Extended Lifespan

A ductless mini split typically lasts 15-20 years, but this lifespan can be shortened if the system isn’t properly maintained. Regular service can help extend the life of your system, allowing you to enjoy reliable cooling or heating for many years.

Better Air Quality

Over time, dirt, dust, and debris can build up inside your mini split’s filters and evaporator coils. Without maintenance, this buildup can reduce the air quality in your home. Regular cleaning ensures your system continues to provide fresh, clean air.

Reduced Repair Costs

Routine maintenance allows technicians to spot small problems before they turn into major issues. By catching these problems early, you can avoid expensive repairs down the road.

What’s Covered in a Mini Split Service?

When a professional arrives for mini split maintenance, they’ll typically perform several important tasks to ensure the system is running smoothly.

1. Cleaning and Replacing Filters: Dirty filters are one of the most common reasons ductless systems operate inefficiently. The technician will clean or replace filters to ensure good airflow and air quality.
2. Cleaning Coils and Condensate Drains: Over time, the evaporator and condenser coils can collect dirt and dust. A technician will clean the coils to maintain proper heat exchange. They’ll also check the condensate drain to make sure water is draining properly, preventing any moisture buildup inside the system.
3. Checking Refrigerant Levels: If your mini split system is low on refrigerant, it can cause the system to work harder, leading to higher energy costs and potential damage. The technician will check the refrigerant levels and top them off if necessary.
4. Inspecting the Outdoor Unit: During maintenance of the outside unit, HVAC technicians typically clean the condenser coils, check for any debris or obstructions around the unit, and ensure proper airflow. They may also inspect the refrigerant levels, check electrical connections, and lubricate moving parts to keep the system running efficiently.

DIY Mini Split AC Maintenance Tips

While professional mini split service is essential, there are several things you can do yourself to keep your system running smoothly throughout the year. These simple DIY tasks can prevent unnecessary wear and tear on your system:

• Clean the Filters Regularly: Dirty filters reduce airflow and can cause your system to overheat. It’s recommended to clean your filters about every two weeks, especially if you live in a dusty area or have pets.
• Keep the Outdoor Unit Clean: The outdoor unit can easily collect dirt, leaves, and debris. Make sure to clear away any obstructions around the unit, as this ensures proper airflow and allows the system to operate efficiently.
• Check for Ice Buildup: If you notice ice forming on the evaporator coils or anywhere else in the system, it could indicate airflow problems or a refrigerant leak. Ice buildup can damage the system, so it’s important to address this issue promptly.
• Inspect the Remote and Controls: Ensure that the remote and system controls are functioning properly. If you notice any glitches, it’s best to have them looked at during your annual service appointment.

Cost of Mini Split Maintenance

The cost of mini split maintenance can vary depending on factors like the size of the system, the complexity of the service, and your location. On average, you can expect to pay between $150 to $300 for a professional mini split service tune-up. This price usually includes a full inspection and cleaning of the system.

However, the cost of regular maintenance is a small price to pay when compared to the potential cost of repairs or premature replacement. In fact, annual maintenance can save you money in the long run by improving the efficiency of your system and preventing costly repairs down the line.
