Comfort at home or work doesn't only depend on the quality of your wall-mounted heat pump. There are several often-overlooked accessories and add-ons that can dramatically improve the performance and experience provided by your HVAC system. At AirGreen, we’ve installed hundreds of wall-mounted heat pumps across Montréal, Laval, Longueuil, the North Shore and the South Shore, and we’ve noticed that certain accessories — although not well known — make all the difference day to day.
Here’s an in-depth look at 7 essential accessories and add-ons we recommend to significantly boost the performance, lifespan, and comfort of your wall-mounted heat pump.
The insulated wall bracket: a stable and quiet base
Often overlooked, the insulated wall bracket plays a crucial role. Not only does it ensure a safe installation of the outdoor unit, but it also reduces vibrations and noise transmitted through the wall — especially important in lightweight structures or condos. This becomes particularly relevant during long periods of heating or cooling.
At AirGreen, we’ve installed reinforced wall brackets with anti-vibration pads in Ahuntsic, Laval-des-Rapides, and Longueuil, particularly in older buildings where noise transmission was a source of complaints. The result: satisfied customers and peaceful neighbors.
The heated condensate drain line: essential in winter
Wall-mounted heat pumps generate condensation water, especially in heating mode. In winter, this water can freeze in the drain line, causing backups and unexpected shutdowns. A simple heating cable integrated into the drainpipe can prevent this issue.
We recommend this device in all installations on the North Shore, especially in Boisbriand, Blainville, and Terrebonne, where winter temperatures are often extreme. It’s a small investment to maintain performance and avoid emergency service calls.
The outdoor line set cover: aesthetic and protective
Beyond its aesthetic purpose — hiding visible pipes and cables — the rigid PVC line set cover protects the lines from UV rays, rain, snow, and small animals. It extends their lifespan and prevents air or water infiltration.
We’ve integrated these line set covers into all our high-end installations in Westmount, Brossard, and the Plateau-Mont-Royal, often color-matched to the exterior siding for a perfect finish.
The smart wall thermostat: for enhanced control
Even though most wall-mounted heat pumps come with remotes, a smart wall thermostat offers considerable benefits: mobile app control, scheduling, occupancy sensors, and multi-zone management.
We’ve installed Mysa thermostats compatible with certain heat pumps in Outremont and Boucherville, allowing our clients to lower their energy usage while maintaining an ideal temperature.
The high-performance filter (HEPA or activated carbon)
Improving air quality is an increasing priority for families, especially in urban areas. A HEPA filter or an activated carbon filter adapted to your heat pump can capture allergens, fine dust, pollen, and even odors.
Our technicians recommend this type of filter in areas with heavy traffic or near industrial zones, such as in Lachine, Laval-Ouest, or East Longueuil.
The refrigerant leak detection device
A refrigerant leak can drastically reduce the performance of your heat pump and pose environmental risks. An intelligent leak detection sensor, either integrated into the system or added to the setup, allows early detection and helps avoid major breakdowns.
This system has already helped our teams prevent costly repairs in Saint-Eustache and Varennes, by alerting clients at the very first signs of a problem.
The snow guard for outdoor unit
On the North and South Shores, winters can bring heavy snowfalls. A metal snow guard mounted above the outdoor unit prevents direct accumulation on the fan, reducing the risk of blockages or equipment damage.
We recently added this accessory to our installations in Mirabel and Saint-Bruno-de-Montarville, following repeated winter interventions. The result: fewer service calls, more peace of mind.
Why these add-ons make all the difference
Including these accessories during installation allows for:
-
Optimized long-term performance
-
Reduced maintenance interventions
-
Improved thermal and acoustic comfort
-
Sustainable energy savings
-
Greater added value for your HVAC installation
What we do at AirGreen
For every wall-mounted heat pump installation in Montréal, Laval, Longueuil, the North Shore and the South Shore, we assess the specific needs of the building and the client. We always recommend the most relevant accessories to maximize your system’s performance while staying within your budget.
A real-life example: in Rosemère, we installed a Gree Lomo 18,000 BTU heat pump with brick-colored line set covers, anti-vibration wall mount, heated drain line, and wall thermostat. The client wanted a discreet, efficient, and quiet system. Three winters later, they’ve never needed to call for an emergency service.
