Benefits of a Ductless Mini-Split AC system

Compared to traditional AC systems, ductless mini-splits have the following benefits:

Flexibility: While heat pumps and central air conditioners force cold air through ducts, mini-split systems deliver warm and cool air directly to specific zones in the house. These systems are also easier and faster to install since they do not require ductwork.

Lower Utility Cost: Unlike traditional systems that operate in a stop-and-start cycle, these mini-splits operate continuously and save up to 40% more energy! Additionally, you only need to heat or cool the needed room rather than the entire house.

Improved Air Quality: The multi-stage filtration of ductless systems drastically reduces the amount of dust, bacteria, allergens, and other particles in the air.

Do Mini Splits Need Annual Maintenance?

Like your car, maintaining a mini-split unit well will help it deliver the comfort you expect more efficiently and for many more years. We recommend an annual clean-and-check service by an HVAC professional.

When we called for ductless mini-split system tune-up and cleaning, here is what we do:

Inspect, clean, or replace the air filters.
Clean removable parts and the fan.
Clean the indoor coil with a commercially available coil cleaner, followed by a light rinse.
Clean the outdoor coil, possibly with a coil cleaning solution, and rinse.
Inspect all other system components, including the mounting hardware, electrical connections, and refrigerant lines.
Check for a refrigerant leak.

As a homeowner, you can do the following mini-split cleaning. But Keep in mind, your safety should be your number one priority.

Clean the indoor unit periodically to keep dirt and dust from accumulating
Check and clean the indoor unit’s air filter every 4-6 weeks. Turn off the system before opening the cabinet.
With the power off, clean the inside of the cabinet.
Inspect the outdoor unit periodically – remove accumulated leaves and other debris from the base of the cabinet,

You can use a garden hose to clean the coils on the outdoor unit when the power is off – do not use a high-pressure nozzle. Be sure that the unit is completely dry before turning it back on.

Types of ductless systems

Ductless air conditioner: used only in the summer to provide complete home comfort efficiently and quietly.

Ductless heat pump: works as a Ductless Air Conditioner in the summer but also delivers excellent heating performance even when the outdoor temperature plummets to -25ºC.

Single-zone & multi-zone

Single zone: connects a single outdoor unit to a single indoor unit. Ideal for heating a room that doesn’t have access to duct-work.
Multi zone: one or more indoor units connect to a single outdoor unit to provide comfort across multiple rooms. Unlike a central system, a multi-zone system can sense and regulate temperature for customized comfort in each zone.
