Installation mistakes can turn a good investment into a nightmare. In Laval, a client recently experienced it the hard way: after entrusting the installation of his wall-mounted heat pump to an inexperienced company, he ended up spending several thousand dollars on repairs… before finally calling AirGreen, experts in HVAC installation across Montréal, Laval, Longueuil, the North Shore, and the South Shore.
A botched installation: when lack of expertise gets expensive
This client in Laval had invested in a Gree Lomo 18,000 BTU wall-mounted heat pump, a unit known for its energy performance, reliability, and eligibility for Hydro-Québec’s LogisVert grant. But within just a few weeks, warning signs appeared: unusual noises, weak performance, unusually high electricity bills…
The cause? A non-compliant installation that failed to follow the manufacturer’s technical specifications:
-
Outdoor unit installed too close to a wall, blocking proper airflow.
-
Improperly angled drain, leading to water infiltrations in the interior wall.
-
Poorly sealed refrigerant lines, causing refrigerant leaks.
AirGreen steps in: full audit, repair, and professional reinstallation
When the client finally contacted AirGreen, our team responded quickly with a full site diagnosis. After reviewing the configuration, we confirmed the installation errors and proposed a three-step action plan:
-
Safe removal of the defective system.
-
Repair of wall damage caused by the faulty drainage.
-
Complete reinstallation of the Gree Lomo 18,000 BTU heat pump, strictly following manufacturer specifications and industry best practices for residential HVAC.
Technical details of the new installation
At AirGreen, every HVAC installation follows a strict protocol:
-
Optimal placement of the indoor unit to ensure even air distribution.
-
Outdoor unit elevated and unobstructed, protected from snow buildup, with proper lateral ventilation.
-
Refrigerant lines properly insulated and slightly angled for smooth condensate drainage.
-
CSA-compliant electrical connection, with a dedicated circuit breaker.
Everything was completed in under a day, with minimal disruption for the client. The result: a quiet, efficient system eligible for a $1,704 LogisVert grant, maximizing the return on investment.
The hidden costs of a bad installation
Beyond the visible issues, a poor installation can cause long-term and costly damage:
-
Compressor overheating, shortening the system’s lifespan.
-
Refrigerant leaks, harmful to the environment and not covered under warranty.
-
Excessive energy consumption, cancelling out the benefits of a high-efficiency heat pump.
For this Laval client, total losses exceeded $3,000 between repair costs, excess electricity usage, and system devaluation.
