The Gree Clivia FRESH AIR R32 18,000 BTU wall-mounted heat pump is aimed at homeowners who want more than just a simple air conditioning unit. In many homes in Montreal, Laval, Longueuil, of the South Shore and the North Shore, the challenge is not only to cool a room in summer or heat efficiently in winter: you also have to deal with humidity, air quality, temperature differences between floors, electrical constraints, the location of the outdoor unit, and the aesthetic integration of the installation.
At AirGreen, we install wall-mounted heat pumps in a wide variety of settings: new condos in Montreal, bungalows in Laval, semi-detached houses in Longueuil, family properties in Montérégie, renovated cottages on the North Shore, rental units, professional offices, and small businesses. What we observe in the field is simple: a good model is not judged solely by its BTU number. You have to look at its heating stability, seasonal efficiency, compatibility with existing installation, noise level, piping, eligibility for subsidies, and quality of after-sales service.
The Gree Clivia FRESH AIR R32 18,000 BTU stands out precisely because of this balance. It combines a nominal capacity of 18,000 BTU, heating performance up to -30 °C, a refrigerant gas R-32, the WiFi included, a certification ENERGY STAR® Cold Climate, and eligibility for a provincial LogisVert subsidy of $2,160 according to the information available on our site as of November 26, 2025.
A unit of 18,000 BTU is often considered for open areas, double living rooms, ground floors, large condos, light commercial spaces, or homes where air circulation is favorable. In the Montreal, we often see this type of need in apartments with open living and dining rooms, where a 12,000 BTU unit might lack reach on humid July days or when the room receives a lot of sunlight.
On the South Shore, especially in Boucherville, Saint-Lambert, Longueuil, or Sainte-Julie, many customers choose the 18,000 BTU size to cover a main floor. On the North Shore, in homes in Laval, Terrebonne, Blainville, or Boisbriand, this size can also be suitable when the staircase, hallways, and interior layout allow for good air distribution.
However, it is important to avoid a common mistake: choosing the BTU solely based on the area. A heat pump that is too powerful can cool quickly without properly dehumidifying. A heat pump that is too weak may run continuously, especially during heatwaves or extreme cold. At AirGreen, we always assess insulation, solar orientation, ceiling height, number of windows, room layout, and usage habits before recommending a capacity.
For this model, the main technical information is as follows:
These data are particularly important for a HVAC installation well-planned. For example, the 16 A MCA and the 20 A MOP mean that the electrical supply must be checked before installation. In some cases, the electrical panel allows direct installation with the correct breaker and wire gauge. In other cases, electrical adjustments are required. We verify this before confirming a final offer to avoid unpleasant surprises on installation day.
The Gree Clivia FRESH AIR uses the gas R-32increasingly common in modern wall-mounted heat pumps. For customers, the advantage mainly translates into a more recent design, good energy performance, and a response better adapted to new HVAC industry standards.
An important element to note: this model includes an A2L leak detection sensor, which is relevant since equipment using new generation refrigerants requires appropriate design measures. For the owner, this adds a layer of safety and confirms that the device is designed for current technical realities.
The mention FRESH AIR often draws attention. In the product sheet, Gree presents the Clivia as a wall-mounted heat pump that can be paired with a fresh air kit optionThis option aims to introduce a certain amount of outdoor air into the space, which can be beneficial in environments where natural ventilation is limited.
However, a clear distinction must be made: a wall-mounted heat pump with a fresh air option does not replace a complete air exchanger system, HRV, or ERV in a home that needs one. It can help improve air renewal in certain configurations, but its effectiveness depends on the installation, the length of the ductwork, pressure, location, and the actual needs of the building.
At AirGreen, we take the time to explain this nuance to clients. For example, in a well-insulated condo in Montreal, a client may want to reduce the feeling of stagnant air in a living area. In a house in Longueuil, the issue may instead be humidity on the ground floor. In a property in North Shore, the priority may be reliable heating in winter. In each case, the same heat pump may be relevant, but the way it is installed and used will not be the same.
Efficiency figures are only useful if linked to real use. The SEER2 of 24.5 indicate very good seasonal cooling performance. For clients in Montreal, Laval and Longueuilis especially important during hot and humid periods when the unit runs several hours a day.
The HSPF2 of 9.0 reflect the heating efficiency over a season. For a wall-mounted heat pump installed in Greater Montreal, this value must be interpreted along with the capacity to maintain heating at low temperatures. Here, the operating capacity down to -30 °C and the power of 14,600 BTU at -15 °C make the model interesting for serious winter use.
The EER2 of 13.65 represents the instantaneous cooling efficiency under specific conditions, while the COP of 3.91 means that under test conditions, the unit can produce several times more thermal energy than it consumes in electricity. In practice, performance varies depending on outdoor temperature, maintenance, settings, filter cleanliness, and installation quality.
Heating up to -30 °C is a strong selling point, but it must be well understood. This does not mean the unit will always deliver its full nominal capacity at all temperatures. The available power gradually decreases as the outdoor temperature drops. For this model, the data given at -15 °C is 14,600 BTU, which remains relevant for a wall-mounted heat pump of this category.
In a recent case on the South Shore, we were called to assess a house where the old wall unit heated well down to about -8 °C but quickly lost efficiency on colder nights. The client thought they would just replace the unit with a model of the same BTU. After analysis, we recommended considering the low-temperature capacity, the orientation of the outdoor unit, and the airflow inside the house. This kind of thinking often makes the difference between an installation that looks good on paper and one that is truly comfortable in January.
One wall-mounted heat pump high-performance can yield poor results if the installation is improvised. For the Gree Clivia FRESH AIR R32 18,000 BTU, several points deserve special attention.
This model uses piping 1/4 - 1/2 in. This information is crucial when replacing an old heat pump. Many homes already have refrigerant lines in place, but they are not always compatible. Reusing incompatible piping can cause performance, noise, pressure, or durability issues.
At AirGreen, we always verify the diameter, condition, accessibility, and routing of the piping. In some cases, it is better to replace the lines to ensure a clean and reliable result. In others, reuse may be possible if technical conditions are met.
The indoor unit measures 39.09 x 8.73 x 12.25 in. This format requires a sufficiently wide wall, adequate clearance, and positioning that allows air to circulate unobstructed. A unit installed too close to a ceiling, above a cabinet, or directed toward a closed corridor can lose some of its efficiency.
In housing of Montreal, we often have to deal with brick walls, moldings, condominium restrictions, or limited drain routes. At Laval and on the North Shore, installations are sometimes simpler in terms of space, but long distances to the outdoor unit must be evaluated. On the South Shore, homes with finished basements often require special attention to drainage and duct routing.
The outdoor unit measures 37.72 x 15.83 x 25.98 in and displays an outdoor noise level of 69 dB(A) according to available data. The location must respect recommended clearances, facilitate maintenance, limit vibrations, and consider snow accumulation.
We often recommend installation on a wall mount, floor table, or suitable base depending on the configuration. In areas exposed to prevailing winds or snow accumulation, improper installation height can cause defrosting issues, noise, or air blockage. These are details we check before installation, as they directly affect the system's lifespan.
The Gree Clivia 18,000 BTU offers automatic control of vertical and horizontal louvers, allowing for better air distribution. This is especially useful in open rooms where you want to avoid a zone that is too cold near the unit and a zone that is too hot at the other end.
The airflow indicated in the technical sheet reaches several levels, with a capacity suitable for a well-sized room. The indoor noise level is indicated at 55 / 50 / 43 dB(A) function varies according to speed. In practice, customers often use a higher speed to quickly reach the desired temperature, then a lower speed to maintain comfort.
The dehumidification is also important. In Greater Montreal, summer humidity can cause discomfort even when the temperature seems reasonable. A properly sized and well-adjusted heat pump can help stabilize comfort without excessively cooling the room.
The WiFi included allows remote control of the heat pump with the Gree app. For many customers, this feature quickly becomes convenient: adjusting the temperature before arriving home, checking the operating mode, reducing cooling during an absence, or restarting heating before arriving at an office.
During our installations, we explain the main functions to avoid setting errors. A common example: a customer thinks the unit is not heating well, when it is in automatic mode and switches according to the ambient temperature. We generally recommend clearly using heating mode in winter, cooling mode in summer, and avoiding too frequent setpoint changes.
According to the information displayed on our site, the Gree Clivia FRESH AIR R32 18,000 BTU is associated with a provincial LogisVert subsidy of $2,160For customers, this assistance can transform the value for money of the project, especially when the installation is done correctly and the required documents are well prepared.
At AirGreen, we know that subsidies can be confusing. Customers often want to know if the model is eligible, what documents are needed, how the application process works, and when the reimbursement can be received. We help our customers better understand these steps and choose a model that meets the criteria displayed at the time of submission.
It is important to check the exact conditions at the time of purchase, as programs may change. We use model numbers, the AHRI number, and ENERGY STAR data to confirm eligibility before making an offer.
A heat pump is technical equipment, but its result depends greatly on the company that installs it. At AirGreen, we don’t just mount a unit on a wall. We analyze the house, electrical supply, piping, drainage, outdoor location, air distribution, customer habits, and building constraints.
We work daily in very different buildings. In Montreal, challenges often involve condominiums, masonry walls, alleys, balconies, and building regulations. In Laval, we see many single-family homes where proper indoor unit placement covers a large living area. In Longueuil and on the South Shore, customers often want an efficient solution for the ground floor without multiplying units. On the North Shore, wind exposure, pipe distances, and outdoor access can influence the design.
This local experience helps us recommend a device like the Gree Clivia FRESH AIR R32 18,000 BTU only when the context truly allows it.
Here are the most common mistakes we encounter during replacements or second opinion requests:
A well-planned installation reduces the risk of service recalls, improves comfort, and extends the heat pump’s lifespan.
To maintain the performance of the Gree Clivia FRESH AIR R32maintenance, we recommend regular upkeep. Filters should be cleaned according to usage, especially if the heat pump runs several hours a day or if the home has pets, a lot of dust, or an open kitchen.
More thorough maintenance may be necessary when the indoor unit accumulates dirt in the turbine or on the evaporator. The most common symptoms are reduced airflow, odors, less effective air conditioning, fan noise, or poor dehumidification. Our team offersHVAC maintenance and cleaning to help owners maintain stable performance.
The Gree Clivia FRESH AIR R32 18,000 BTU can be an excellent choice for:
It is not automatically the right choice for every project. If the space is smaller, a 9,000 or 12,000 BTU model may be more appropriate. If multiple closed rooms need to be treated, a multi-zone solution may better meet the need. If the building has a major ventilation issue, an air exchanger or complementary solution may need to be considered.
At AirGreen, we prepare clear offers before work begins. We explain what is included, what may incur an extra charge, and which options might be relevant. Our goal is for the customer to understand exactly what they are buying: the product, installation, warranty, electrical conditions, piping, accessories, subsidies, and after-sales service.
We are also available after installation to answer questions about settings, WiFi, maintenance, winter heating, and optimal use of the device. This approach is important because a well-used heat pump often delivers better results than a high-performance device that is poorly configured.
The Gree Clivia FRESH AIR R32 18,000 BTU wall-mounted heat pump combines several qualities sought by Greater Montreal homeowners: high efficiency in cooling, heating up to -30 °C, refrigerant R-32, WiFi included, certification ENERGY STAR® Cold Climate, fresh air kit option, power suited for large living areas, and eligibility for a significant provincial subsidy.
For an owner of Montreal, Laval, Longueuil, of the South Shore or the North Shore, this model deserves serious consideration when a space requires a robust, efficient wall-mounted solution professionally installed.
