Breathing New Life into a GOLDSTAR Heat Pump – A Story of Skill, Dedication, and Success
At AirGreen, we take immense pride in our ability to tackle HVAC challenges with precision and professionalism. Our latest service call in Montréal perfectly exemplifies our commitment to customer satisfaction and technical excellence. This time, we encountered a GOLDSTAR wall-mounted heat pump that was believed to be beyond repair. What unfolded next is a testament to our expertise and the value we bring to each customer interaction.
A Cry for Help: The Backstory
The customer reached out to us with a dire situation. Their GOLDSTAR ductless heat pump, once a reliable companion for Montreal’s diverse climate, had suddenly stopped functioning. Having served them well for years, the unit’s failure came as a significant setback, especially with winter approaching. The customer was prepared to invest in a new system, believing the existing one was beyond saving.
But at AirGreen, we always advocate for a thorough inspection before jumping to conclusions. After all, repairing an existing system can often be more cost-effective and environmentally friendly than replacing it entirely.
The Inspection: Diagnosing the Problem
Upon arrival, we conducted a comprehensive inspection of the unit. Here’s what we discovered:
- Electrical Issues: The power connections had degraded over time, causing intermittent functionality.
- Refrigerant Concerns: The refrigerant levels were alarmingly low, likely due to a minor leak.
- Blocked Filters and Coils: The indoor and outdoor components were heavily clogged with dirt and debris, reducing the system's efficiency.
While these issues seemed daunting at first glance, our experienced technicians knew they could restore the unit with the right approach and tools.
The Repair Process: Step by Step
1. Electrical Repairs
We began by addressing the power connections. Using high-quality replacement parts, we repaired the damaged wiring and ensured all connections were secure. This step immediately resolved the intermittent power failures.
2. Leak Detection and Refrigerant Recharge
Next, we pinpointed the source of the refrigerant leak using advanced detection tools. After sealing the leak, we recharged the system with the appropriate refrigerant, ensuring optimal cooling and heating performance.
3. Deep Cleaning
To improve airflow and system efficiency, we performed a meticulous cleaning of both the indoor and outdoor units. This included:
- Washing the coils to remove dirt and grime.
- Cleaning and replacing the filters.
- Inspecting and cleaning the fan blades for smooth operation.
4. Comprehensive Testing
Finally, we ran the unit through rigorous tests to confirm it was functioning as intended. The results? The heat pump was back to its former glory, ready to serve the customer for years to come.
Why Repair Instead of Replace?
While replacing a unit can sometimes be the best option, repairing an existing system has its advantages:
- Cost-Effectiveness: The repair cost was significantly lower than the price of a new unit.
- Environmental Benefits: Extending the life of an HVAC system reduces waste and the environmental impact of manufacturing new components.
- Familiarity: The customer was already accustomed to their GOLDSTAR unit and didn’t have to learn the nuances of a new system.
Customer Reaction: A Pleasant Surprise
The customer was overjoyed when we informed them that their beloved heat pump was not only repairable but now functioning as efficiently as when it was first installed. They appreciated our honesty, technical expertise, and dedication to finding the most practical solution for their needs.

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.
