An essential comparison for any homeowner looking to invest in a reliable, high-performance wall-mounted heat pump
At AirGreen, we receive weekly inquiries from clients across Montréal, Laval, Longueuil, as well as the North and South Shores, who are torn between choosing a wall-mounted LG heat pump or a wall-mounted Panasonic heat pump. These are two world-renowned brands with different engineering philosophies, but the same goal: to deliver optimal comfort year-round.
To help you make an informed decision, we’ve put together a rigorous technical comparison based on our real-world HVAC installation experience with clients, technical spec sheets, and long-term user feedback after several years of operation.
LG: Innovation and Smart Control Delivering High Performance
Model analyzed: LG Prestige | 12,000 BTU | R-32
This model has become a popular choice in many of our recent installations across Montréal and Longueuil. It stands out for:
-
Its Dual Inverter compressor, offering exceptional energy efficiency and reducing temperature fluctuations.
-
Built-in Wi-Fi connectivity, allowing remote control via the LG ThinQ app.
-
Very low noise levels (as low as 19 dB on the lowest fan setting), perfect for bedrooms.
-
An excellent SEER of 27.5 and HSPF of 13.5, fully aligned with provincial grant program requirements.

In a recent project in Saint-Hubert, the LG Prestige was installed in a 1,000 sq. ft. condo. Thanks to its smart control features, the client was able to schedule operation according to daily routines, cutting electricity use by over 35% compared to the previous system.
Panasonic: Japanese Durability and Premium Air Filtration
Model analyzed: Panasonic XE12WKUA | 12,000 BTU | R-32
Panasonic focuses heavily on indoor air quality, a major factor for urban areas like Laval or Montréal. Its standout features include:
-
Nanoe™ X technology, which releases particles that neutralize viruses, mold, allergens, and odors.
-
Consistent energy performance, with a SEER of 23 and an HSPF of 12.5.
-
Reliable auto-restart system, practical during winter power outages.
-

Installation: What You Need to Know to Plan Your Project
During our HVAC installations in Montréal and on the North Shore, several factors influence the decision between these two models:
-
Indoor placement: in bedrooms, LG may be favored due to its ultra-quiet operation.
-
Allergy sensitivity: for sensitive occupants, Panasonic becomes the logical choice.
-
Built-in Wi-Fi: for clients looking for full mobile automation, LG is the winner.
-
Open layouts or complex configurations: both models require proper BTU sizing and strategic unit placement to optimize airflow.
AirGreen’s Top Tips for Making the Right Choice in 2026
-
Consult an HVAC expert before ordering. Our technicians assess your actual needs and the constraints of your home.
-
Don’t rely solely on technical specs. Real-world use depends on occupancy type, building orientation, and even lifestyle habits.
-
Go with certified installation. A poorly installed heat pump can cancel out its benefits and lead to issues like water infiltration or lower efficiency.
-
Compare available rebates. Our advisors can check your LogisVert eligibility based on your postal code.
-
Plan for annual HVAC maintenance, essential for maintaining performance and validating warranties.
