Understanding the importance of warranty when choosing a multizone heat pump in Montreal
In the HVAC field in Montreal, choosing a multizone heat pump isn’t just about comparing BTU power or energy efficiency. One often overlooked, yet critical criterion for any homeowner or property manager is the manufacturer’s warranty. At AirGreen, we’ve installed hundreds of multizone heat pumps across Montreal, Laval, Longueuil, the North Shore and the South Shore, allowing us to provide a clear and accurate analysis of the best warranties currently available on the market.
Why is the warranty a decisive factor?
The warranty of a multizone heat pump is more than just a technical document. It’s a promise: a guarantee of peace of mind for the user, and a clear indicator of the manufacturer’s confidence in their product’s durability. In Montreal, where temperature swings can be extreme, a strong warranty means protection from unexpected costs.
Key criteria when analyzing multizone warranties
To effectively evaluate the warranties offered by ACD, Bosch, LG, and Gree, we based our analysis on concrete factors:
-
Length of warranty on parts (including or excluding compressor)
-
Scope of the warranty (parts, labor, compressor separately)
-
Transferability if the property is sold
-
Conditions for activation (installation by certified professional, product registration, annual maintenance, etc.)
-
Local support in Quebec / parts availability in case of malfunction
1. ACD: a reliable warranty suited to Quebec’s climate
ACD multizone heat pumps, a well-known brand in Quebec, offer a limited 10-year warranty on parts and the compressor, provided installation is done by a certified contractor and the unit is registered within 60 days.
Strengths:
-
Simple and transparent warranty.
-
Local parts availability.
-
Fast local technical support.
Limitations:
-
No extended labor warranty.
-
Not automatically transferable upon resale.
On-site experience with AirGreen: We’ve installed multiple ACD multizone systems in Saint-Eustache, Brossard, and Ahuntsic, with few issues. Clients appreciate their winter reliability and the local service.
2. Bosch: solid warranty with premium service
Bosch multizone heat pumps, like the BOVA series, are well known for their inverter technology and high efficiency. Bosch stands out by offering a limited 10-year warranty on parts, often accompanied by an extended labor program through certified installers.
Strengths:
-
Proven durability in cold climates.
-
Option for labor coverage through AirGreen.
-
Warranty can be transferable in some cases.
Limitations:
-
Requires prompt product registration.
-
Parts replacement can be slower than some other brands.
AirGreen field report: A client in Boisbriand received a compressor replacement under warranty after 8 years. Bosch covered the part, and AirGreen handled the labor under the extended service agreement.
3. LG: advanced technology and standard coverage
LG offers highly advanced multizone heat pumps, particularly in its Multi F line. The standard warranty includes 10 years on the compressor and 5 to 10 years on parts, depending on registration.
Strengths:
-
Recognized technology (Dual Inverter, Wi-Fi).
-
Solid performance in multizone applications.
Limitations:
-
Little to no labor warranty coverage.
-
Longer wait times for parts in Montreal.
AirGreen observations: We installed an LG multizone system in a triplex in Rosemont: while performance was excellent, the warranty terms lacked clarity for the customer. We implemented an internal follow-up program to assist them.
4. Gree: the most complete warranty on the market
Gree, a major global manufacturer, offers with its Multi21+ and MultiZone Ultra models a comprehensive 10-year warranty on parts AND the compressor, including labor in several partner programs like the one offered by AirGreen.
Strengths:
-
One of the most complete warranties.
-
High reliability of multizone models.
-
Ultra-fast service response with AirGreen.
Limitations:
-
Requires authorized installer to validate full warranty.
Real AirGreen installation: We installed a Gree MultiZone Ultra 36,000 BTU system in a home in Sainte-Julie. The client benefited from a 10-year parts + labor warranty, with a 24-hour response when a minor thermostat adjustment was needed.
Our recommendation: Gree leads, followed by Bosch
For clients looking for the best multizone warranty in Montreal and surrounding areas, our ranking is as follows:
-
Gree – for its 10-year parts + labor warranty, proven performance, and excellent technical support.
-
Bosch – for its reliability and interesting labor extension options.
-
ACD – a simple, Quebec-friendly solution.
-
LG – solid performance but less competitive warranty conditions.
AirGreen tips: what to avoid when it comes to warranties
-
Never overlook product registration: this often invalidates extended warranty coverage.
-
Always request a service contract if labor isn’t covered.
-
Choosing a certified and recognized installer, like AirGreen, is often a mandatory condition for full warranty validity.
