The article, chapter by chapter
When our team at AirGreen received a call about a malfunctioning LG Mini Split Heat Pump in the picturesque suburb of Baie-D'Urfé, we knew we had to act quickly. The homeowner had been experiencing inconsistent heating and cooling, a particularly inconvenient issue as the unpredictable weather in the area demanded reliable indoor comfort. With our tools packed and expertise ready, we headed out to diagnose and repair the issue.
The First Step: Thorough Diagnostics
Upon arrival, we noticed that the LG Mini Split Heat Pump, a popular ductless system known for its energy efficiency and quiet operation, was struggling to maintain the set temperature. The homeowner mentioned unusual noises coming from the indoor unit and occasional water drips, signaling potential drainage issues.
Our technicians began with a comprehensive system evaluation, checking:
- Indoor Unit: Filters, blower, and evaporator coil condition.
- Outdoor Unit: Condenser coils, fan operation, and refrigerant levels.
- Drainage System: Ensuring proper flow and absence of clogs.
- Electrical Components: Verifying connections and system controls.
The issue was a combination of a partially clogged drainage line and a refrigerant level below the manufacturer’s recommended threshold.
Addressing the Drainage Issue
Drainage issues are common in mini split systems, particularly if regular maintenance is overlooked. Dust, mold, and debris can accumulate in the drain line, causing water to back up into the unit. To fix this, we:
- Flushed the drain line with specialized cleaning agents.
- Cleared the condensate pump, ensuring it could efficiently handle water buildup.
- Checked for any cracks or leaks in the drainage components.
After completing these steps, we ran the system to confirm proper water flow and ensure no further blockages.
Replenishing the Refrigerant
Low refrigerant levels can significantly impact the performance of a heat pump, leading to inadequate heating or cooling. Using state-of-the-art tools, we checked for leaks in the refrigerant lines. Finding none, we proceeded to carefully replenish the refrigerant to the exact levels required by LG’s specifications.
Final Touches: Cleaning and Testing
We didn’t stop there. To ensure optimal performance, we also:
- Cleaned the indoor unit’s filters and evaporator coil, improving airflow.
- Cleared debris from the outdoor unit’s condenser coil, ensuring efficient heat exchange.
- Calibrated the system controls and tested multiple modes (cooling, heating, and fan-only).
After running a series of tests, the system was back to operating at peak efficiency, providing the homeowner with a consistent and comfortable indoor climate.

What we check on a job like this one
Each number is a point we check on site. Switch between summer and winter to watch air and heat move.
In summer, the outdoor unit rejects the house's heat outside.
Generic illustration of this type of installation, not a survey of this job site. Tap a number.
Mounted level on a wall plate, high enough for the air to reach the whole room, with enough space around it to slide the filters out easily.
The refrigerant lines, the communication cable and the drain go through the wall in a single opening, sealed against water, cold air and insects.
Two insulated copper pipes connect the two units. Outside, a line cover can protect them from sun, knocks and weather.
A shut-off switch near the outdoor unit isolates it safely for service. It must stay accessible at all times.
The compressor and the fan. In heating mode it captures heat from the outdoor air, even in winter, and moves it inside.
On the ground or on the wall, it keeps the unit above accumulated snow. The unit stays clear and defrost water can drain away.
The fan needs to blow freely. Storage, a fence or a wall too close, and efficiency drops while noise goes up.
Good habits, once the unit is in place
Six simple habits that keep the unit going. Your list stays on this device.
What to do, season by season
Three habits per season for this unit. They take a few minutes and prevent many calls.
- Clean the indoor unit's filters.
- Clear leaves and debris left on the outdoor unit by winter.
- Test cooling before the first hot days.
- Clean the filters more often when the unit runs a lot.
- Keep plants away from the outdoor unit.
- Check that no water drips from the indoor unit.
- Rake the leaves around the outdoor unit.
- Test heating before the first cold days.
- Book periodic maintenance before winter.
- Keep snow away from the stand and the front of the unit.
- Let the unit defrost: it is normal.
- Never hit the ice on the fins; call us if the unit stays iced up.
The right pages, at the right time
Four statements: true or false?
It all comes down to details you have just seen.
1. In heating mode, the outdoor unit can produce water.
During defrost cycles. That water must drain away without forming ice.
2. You pick the capacity with a simple square-footage rule.
Windows, insulation, orientation and how the room is used all count. Capacity is chosen on site.
3. A multi-zone connects several indoor heads to a single condenser.
One head per room, all on the same condenser. Each room keeps its own temperature.
4. The disconnect can sit behind the patio furniture.
It must stay accessible: it is what shuts the unit off for service.
