A decade of technological transformation in the world of wall-mounted heat pumps
Over the past ten years, the wall-mounted heat pump industry has undergone a true revolution, both technically and in terms of user experience. At AirGreen, experts in HVAC installation in Montreal, Laval, Longueuil, North Shore and South Shore, we've been front-row witnesses to this transformation. As field specialists, we’ve seen customer expectations evolve, installation constraints shift, and—above all—manufacturer innovations flourish. Today’s wall-mounted heat pumps are nothing like those from a decade ago: optimized energy performance, ultra-compact design, built-in intelligence, and better integration into homes have all become the new standard.
Today’s energy performance far surpasses yesterday’s expectations
Modern wall-mounted heat pump models display significantly higher Coefficient of Performance (COP) and Seasonal Energy Efficiency Ratios (SEER/HSPF) than older systems. For example, a 12,000 BTU unit installed in 2013 might have had a SEER rating around 15. Today, models like the Gree Sapphire or the Fujitsu KZAH R-32 easily exceed SEER 25, all while providing stable heating even at -30°C, ideal for the harsh winters of Greater Montreal.
These aren’t just theoretical improvements: in a project in Sainte-Julie, we replaced an older system with an 18,000 BTU Gree Sapphire wall-mounted heat pump. The result? A 40% reduction in the customer’s energy bill, along with a noticeable improvement in comfort, even in the most exposed rooms.
Redesigned aesthetics for better integration
Previously bulky and unattractive, today’s indoor wall units are now compact, sleek, and quiet. Manufacturers have understood that discretion is a key concern for users. The Sharp ZU1 model, for instance, is one of the most stylish we install in condominiums in Town of Mount Royal or contemporary homes in Brossard. It blends seamlessly with all interior styles.
We recently carried out an HVAC installation in Laval in a mid-century style renovated home. The client was looking for an efficient yet discreet solution. They chose the 15,000 BTU Sharp ZU1 wall-mounted heat pump, whose glossy white finish and slim profile were a perfect fit. The installation was completed with no visible ductwork, thanks to our team’s meticulous planning.
Artificial intelligence meets thermal regulation
The new generation of wall-mounted heat pumps does more than just heat or cool: they learn and adapt. Today’s systems are equipped with presence sensors, Wi-Fi controls, and even predictive thermal algorithms. The Bosch BIVA IDS Premium model, which we installed in Boisbriand, can modulate its power based on room occupancy, boosting efficiency while lowering energy use.
Noise reduction: silence is the new standard
One of the most striking advancements is the drastic reduction in noise. Ten years ago, a wall-mounted heat pump typically ran at 40 to 50 dB during normal use. Today, models like the Fujitsu KZAH R-32 can go as low as 19 dB—barely more than rustling leaves. This level of quiet is especially appreciated in urban projects, such as in Downtown Montreal or Longueuil, where indoor peace is a major comfort factor.
Grants and incentives: an added bonus
Government subsidy programs have also evolved to match market innovation. Hydro-Québec, through the LogisVert program, now offers up to $2,172 in grants for installing Energy Star-certified wall-mounted heat pumps. This financial boost motivates many homeowners to upgrade their heating and cooling systems.
At AirGreen, we factor these incentives in from the consultation stage. For example, during a recent installation in Sainte-Marthe-sur-le-Lac, we guided the customer toward an 18,000 BTU Gree Extreme wall-mounted heat pump that qualified for the maximum subsidy. The outcome: a high-performance system and a faster return on investment thanks to government support.
A new approach to HVAC installation
With more advanced and complex machines, our role as HVAC installers has become even more strategic. A thorough thermal analysis, careful selection of indoor and outdoor unit placement, and flawless installation are essential to ensure system longevity.
Our technicians receive continuous training and are fully versed in the new R-32 and R-454b refrigerant standards that have replaced the older R-410A gases. These new refrigerants are not only more eco-friendly but also more efficient. For instance, we installed a 24,000 BTU Goodman R-32 in a home in West Laval, optimizing duct pathways to avoid any performance loss.
The takeaway: investing today pays off across the board
The technological leap in wall-mounted heat pumps over the past decade isn’t just a cosmetic upgrade. It represents a qualitative transformation that directly impacts energy consumption, thermal comfort, equipment durability, and even property value.
At AirGreen, we’ve supported this shift every step of the way. With hundreds of installations completed throughout Montreal, Laval, Longueuil, the North Shore and South Shore, we know how to tailor each project to today’s modern demands.
