Diagnose my heating system

A heating service tailored to Montreal buildings

In Montreal, a heating system must be chosen and maintained according to the building’s specifics: a condo with co-ownership rules, an old duplex or triplex, a plex with alley access, a house with existing ducts, an outdoor unit on a balcony or flat roof, a compact mechanical room, a limited electrical panel, or a dwelling with different comfort zones. At AirGreen, we analyze these constraints before recommending a repair, replacement, or new installation.

Types of heating systems serviced by AirGreen in Montreal

Heating & Air Conditioning

A popular solution for heating and cooling a room, a condo, a plex, or a specific area. It is ideal when the building has no ducts and you want to improve comfort without installing a complete central system.

Wall-mounted heat pump
Heating & Air Conditioning

A single outdoor unit connected to multiple indoor units to control comfort in different rooms or on different floors. This is an interesting solution for plexes, multi-story houses, large condos, and Montreal buildings where needs vary from one area to another.

Multi-zone heat pump
Heating & Air Conditioning

For projects where a traditional wall unit is not ideal, AirGreen offers more discreet or specialized heating solutions: ceiling cassette, ducted unit, low console, and floor-ceiling unit. These systems can be very useful in condos, multiplexes, houses, or commercial spaces in Montreal where aesthetics, wall space, air distribution, or room layout require a more personalized approach.

Cassette units, ductable, console, and floor-ceiling units
Heating & Air Conditioning

A complete central system typically includes a central indoor unit, such as an electric furnace or an air handler, combined with an outdoor unit, like a central heat pump. This solution allows heating and cooling of the entire property through an existing or newly adapted duct network.

Complete central system
Heating & Air Conditioning

The “Add-On” solution is designed to add a central heat pump to an existing central system. It improves heating efficiency and adds central air conditioning, while retaining certain existing components when their condition, compatibility, and the building’s configuration allow.

Central Heat Pump “Add-On”
Heating Only

An electric furnace is a reliable solution for central forced-air systems. It can serve as the main heating source or be combined with a central heat pump to provide supplemental heating during colder periods.

Permits and Regulations for Installing a Heating System in Montreal

Is your heating not working properly anymore?

A heating problem can quickly become urgent during the winter in Montreal. Before replacing a device, it is important to first understand the real cause of the problem: settings, thermostat, filter, ventilation, defrosting, electrical component, refrigerant, or air distribution. AirGreen provides a clear diagnosis to help you determine whether your system can be repaired, optimized, or if it needs to be replaced.

Heating Maintenance in Montreal: Prevent Breakdowns Before Winter

Heating maintenance helps identify problems before they become urgent. In Montreal, waiting for the first cold snap to check your system can lead to delays, discomfort, and more costly repairs. AirGreen recommends having systems checked before the cold season, especially when a device heats less effectively, consumes more, or makes unusual noises.

Why choose AirGreen for your heating service in Montreal?

In Montreal, a heating system cannot be chosen lightly. It must be reliable, properly sized, and capable of maintaining comfort during periods of intense cold. AirGreen offers solutions adapted to the Quebec climate, whether for a wall-mounted heat pump, a central heat pump, an electric furnace, or a complete HVAC system.

Whether it's for a diagnosis, repair, maintenance, replacement, or installation, AirGreen takes the time to explain the options before starting. You know what needs to be done, why it is recommended, and which factors may affect the price. Our goal is to avoid unpleasant surprises and help you make an informed decision.

Our technicians work with different types of HVAC heating systems: wall-mounted heat pumps, central heat pumps, electric furnaces, multi-zone systems, ducted units, cassettes, and central systems. This experience allows for better problem diagnosis, proper installation of equipment, and performance optimization according to the needs of each property.

AirGreen is not just an online company or a simple phone number. We have a physical address with a showroom in Boucherville, where you can come meet real people, ask your questions, see some equipment, and discuss your project with our team. For your heating needs in Montreal, you are dealing with an established, accessible, and very real company that understands the demands of Quebec winters and the realities of Montreal buildings.

AirGreen works with a professional and organized approach: RBQ # 5645-9605-01, 5M$ liability insurance, clear communications, serious follow-up, and documented processes. For heating services in Montreal, you are dealing with an established, structured, and responsible company.

AirGreen does not automatically recommend replacement. The right choice depends on several factors: the age of the system, the cost of repair, the availability of parts, current performance, energy consumption, and possible subsidies. If a repair is cost-effective, we will explain it to you. If a replacement becomes more logical in the long term, we will tell you clearly.

We do not recommend the same heating system to everyone. Each project is evaluated based on the building configuration, access, area, insulation, desired comfort level, budget, electrical capacity, existing ducts, unit locations, and technical constraints. The goal is simple: to offer a heating solution that truly works for your space, your winter, and your reality — not a standard option applied to all buildings.

Heating, heat pumps, and subsidies in Montreal

Changing a heating system can represent a significant investment, but some projects may be eligible for financial aid programs depending on the type of equipment installed, its performance, capacity, building configuration, and the rules in effect at the time of the work.

In Montreal, an efficient heat pump, a central heat pump, an electric furnace combined with a more efficient solution, or a conversion to a more modern heating system can sometimes help reduce the total project cost. AirGreen can help you check the available options before choosing your equipment.

Since programs change over time, we avoid general promises. Our approach is simple: validate eligibility based on your building, your equipment, and your actual project, then guide you toward a reliable, efficient heating solution suited to Montreal winters.
