Mini-Split/ Ductless Maintenance
Intro:
Mini Splits/ Ductless systems are a great option to install in home additions, server rooms, tight rooms, offices and/or garage conversions. Although, just like with everything it will need to be maintained periodically. Depending on the environment, living style, pets, and other factors will determine how often the equipment will need to be serviced, and to what extent of cleaning is required.
Why Maintenance?
These systems are designed to operate in clean environments, which helps minimize the need for frequent servicing and reduces downtime. Most ductless systems feature two to three removable, washable filters located on the top of the unit. These filters can typically be rinsed off with a garden hose. In cases where buildup is heavier—such as grease or stubborn dirt—a degreaser or cleaning solution may be necessary to loosen debris before rinsing.
​
Common indoor pollutants like dust, pet dander, household cleaning chemicals, fragrances, cooking odors, VOCs, and other organic vapors can cause buildup on the filters, evaporator coil, and blower wheel. While the top filters help capture some of these particles, they are not able to trap everything. Over time, unfiltered particles pass through the coil, leading to dirt accumulation on the coil and blower components.
As the cross-flow blower wheel and the surrounding area become dirty, system performance begins to degrade. Airflow is reduced, making it harder for the unit to properly cool or heat the space within the expected time frame. Similar symptoms occur if the coil becomes clogged on the surface or within the fin pack, further reducing efficiency.
​
The outdoor condenser also requires regular cleaning. Units installed close to the ground or in dusty areas are especially prone to coil contamination, which can decrease efficiency and eventually lead to mechanical failure. The electrical compartment within the condenser—often overlooked—also collects dust and should be inspected during maintenance.
​
One effective way to keep the outdoor condenser cleaner is by installing it on a wall bracket. In addition to elevating the unit away from dirt and debris, a wall bracket protects it from potential damage caused by pets, lawn equipment, and daily activity. It also improves service accessibility, making maintenance quicker and easier.
Our Maintenance Processes:
Our maintenance process is a comprehensive and highly detailed service that addresses every component of your ductless system. We specialize exclusively in ductless maintenance and cleanings, with extensive hands-on training across all major brands. Using specialized equipment designed specifically for ductless systems, we ensure that every job is completed thoroughly, efficiently, and safely.
​
Indoor Unit Maintenance:
​
We begin by fully disassembling the indoor unit—removing filters, the front coil cover, and the entire plastic housing. These components are taken outside and treated with a cleaning agent to lift accumulated dirt, dust, microbial growth, and odors. Each piece is then carefully scrubbed and sanitized with a disinfectant that adheres to the plastic, helping to prevent future contamination.
The indoor coil is cleaned using a motorized pump system that delivers the ideal amount of water pressure—strong enough to flush out debris but gentle enough to protect the coil fins. A non-toxic cleaning solution is introduced into the water to remove grease, biological buildup, and stubborn dirt. Our equipment features specialized attachments that allow us to reach behind the coil and directly access the cross-flow blower wheel for a deep clean.
All runoff water and debris are captured by a custom-designed containment system to ensure a mess-free process. We then clean and scrub the drain pan, applying a fungistatic coating to help inhibit future microbial growth. The drain line is flushed thoroughly to ensure proper water flow.
​
Outdoor Condenser Maintenance:
​
The outdoor condenser is also fully disassembled. All housing components are scrubbed and treated with a cleaning solution. The condenser coil is cleaned with an alkaline-based agent to break down dirt, dust, and grime. We remove and clean the fan blade, inspecting it for cracks, warping, or bearing wear that could affect performance. The motor shaft is also cleaned and lubricated to prevent the fan blade from seizing over time.
Finally, we clean the electrical compartment, including the circuit boards, using soft brushes and compressed air. This ensures that sensitive components remain free of dust and debris, reducing the risk of electrical shorts and system failure.
