Why Regular Cleaning of Your Heat Pump is Essential: A Case Study in Brossard
When it comes to HVAC maintenance, there’s nothing more crucial than keeping your wall-mounted heat pump in top-notch condition. Recently, our team at AirGreen was called to Brossard, on the South Shore, to perform a complete cleaning and maintenance service on a mini-split unit. What we found was not uncommon, but it served as a reminder of how vital regular maintenance is for the longevity and efficiency of your heat pump.
The Challenge: An Overlooked Mini-Split in Dire Need of Care
Our client in Brossard had noticed a decline in the efficiency of their wall-mounted heat pump, along with an increase in energy consumption. It’s a scenario we encounter quite often: homeowners might not realize that over time, dust, dirt, and other pollutants can accumulate on the filters and coils of their mini-split system. This buildup not only hampers the unit’s performance but can also lead to higher energy bills and even potential health hazards due to poor indoor air quality.
The Initial Inspection
When we arrived, the first step was to thoroughly inspect the system. As you can see from the image provided, the filters were heavily coated with dust and grime. This is a common issue, especially if the unit hasn't been serviced in over a year. The dirt acts as a barrier, reducing airflow and forcing the unit to work harder to maintain the desired temperature.
Our Comprehensive Cleaning Process: Bringing the Mini-Split Back to Life
Step 1: Deep Cleaning the Filters
The filters are the heart of any mini-split system. They trap dust, allergens, and other particles, ensuring that the air circulating in your home is clean and healthy. For this Brossard installation, we removed the filters and gave them a deep cleaning using our specialized HVAC cleaning solutions. This process not only restores the unit’s efficiency but also improves indoor air quality.
- Why Is This Important? Clean filters ensure optimal airflow, which means your system doesn’t have to work as hard to cool or heat your home. This leads to energy savings and a longer lifespan for your unit.
Step 2: Cleaning the Coils and Fins
The evaporator coils and fins were also covered in a thick layer of grime. This is a common problem that can drastically reduce the efficiency of a heat pump. We carefully cleaned these components using specialized tools designed to remove dirt without damaging the delicate fins. This step is crucial because dirty coils can cause your system to overheat and potentially lead to expensive repairs.
- Did You Know? Clean coils can improve the efficiency of your heat pump by up to 30%, making a noticeable difference in your energy bills.
Step 3: Checking the Drainage System
Another critical aspect of our maintenance service is ensuring that the drainage system is functioning correctly. In this case, we discovered a blockage caused by accumulated debris. This can lead to water leakage and even mold growth if left unchecked. We cleared the blockage and ensured that the drainage system was working perfectly, preventing future issues.
Step 4: Final Inspection and Testing
After completing the cleaning process, we conducted a thorough inspection of the entire system to ensure that everything was functioning correctly. We tested the unit's cooling and heating capabilities, checked for any unusual noises, and made sure that the airflow was back to optimal levels.
The Results: A Mini-Split Restored to Peak Performance
Once the cleaning and maintenance were completed, our client in Brossard noticed an immediate improvement in the performance of their mini-split heat pump. The air quality was significantly better, the unit was running more efficiently, and their energy bills were expected to decrease in the coming months.

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.
