Ductless Mini-Split Maintenance

Why Should You Have Your Ductless System Maintained?

Ductless mini-split systems are often neglected for one simple reason: many homeowners have never been told they need regular maintenance. It is surprising how many people don't realize that their ductless system should be professionally cleaned every year, or at the very least every two years, depending on how often it is used and the environment it operates in.

Over the past several years, ductless mini-splits and heat pumps have become increasingly popular across Canada. While they are highly efficient systems, they are also more sensitive to dirt and airflow restrictions than a traditional forced-air furnace. Because of this, we regularly find problems that could have been prevented with routine maintenance.

One of the Biggest Problems: Dirty Blower Wheels

One of the most common issues we see is a dirty indoor blower wheel.

Unlike a furnace blower, the cross-flow blower wheel inside a ductless indoor head has small blades that can quickly become coated with dust, pet hair, and other debris. As dirt builds up, airflow is reduced and the unit has to work harder to move air through the evaporator coil.

Restricted airflow can lead to:

Poor cooling or heating performance.
Reduced efficiency.
Indoor coil icing during cooling.
Water leaks caused by ice melting.
Increased wear on the blower motor.

A dirty blower wheel is one of the most common causes of poor performance in ductless systems.

Dirty Filters

Every ductless indoor head contains washable air filters. If these filters are not cleaned regularly, airflow becomes restricted, reducing the unit's ability to transfer heat.

Poor airflow can contribute to:

Frozen indoor evaporator coils.
Reduced cooling capacity.
Higher energy consumption.
Poor heating performance during the winter.

Fortunately, cleaning the filters is simple, and we inspect them during every maintenance.

What Is Included in Our Ductless Maintenance?

The type of maintenance depends on the condition of your system and the level of cleaning required.

Full System Maintenance

Our full ductless maintenance includes:

Cleaning the indoor head.
Cleaning the blower wheel (either in place using specialized cleaning equipment or by removing it when necessary).
Cleaning the indoor evaporator coil.
Cleaning the washable air filters.
Inspecting the condensate drain.
Cleaning the outdoor condenser coil (when required).
Checking refrigerant operating pressures.
Measuring supply and return air temperatures.
Inspecting electrical components.
Confirming the system is operating properly.

Indoor Head Cleaning

Sometimes only the indoor head requires cleaning. If the outdoor unit is clean and operating properly, an indoor head cleaning may be all that's needed.

This service includes:

Cleaning the blower wheel.
Cleaning the indoor evaporator coil.
Cleaning the washable air filters.
Inspecting the condensate drain.
Verifying proper operation of the indoor unit.

If, during our inspection, we determine the outdoor unit would also benefit from cleaning or further testing, we'll discuss our recommendations with you before proceeding.

Regular maintenance helps keep your ductless system operating efficiently and allows us to identify developing problems before they become costly repairs.
