Indoor comfort settings on most units are adjustable up to (75°F) this refers to the thermostat's comfortable cooling setpoint range, not the outdoor operating limit of the equipment (see Temperature Range, below, for the outdoor ambient ratings). Many come with standard remotes, timer features, and Wi-Fi connectivity for app-based control.
Another advantage of choosing GREE is the easy availability of spare parts, which keeps long-term maintenance affordable.
While GREE’s value and efficiency are attractive, their customer support network in North America — particularly in Canada — remains limited. Assistance is primarily offered through professional HVAC dealers rather than directly from the manufacturer, which can make troubleshooting or warranty service a slower process.
Some homeowners also mention that outdoor units can be a bit noisy, and the mobile control app, while functional, could be more intuitive. Build quality is generally solid but doesn’t quite reach the refined feel of higher-end brands such as Mitsubishi.
In summary: GREE heat pumps are cost-effective, efficient, and environmentally conscious. However, they may not suit homeowners looking for ultra-quiet operation or strong after-sales support.
We regularly review homeowner experiences and installer feedback across Canada to assess how GREE heat pumps perform in real-world conditions.
GREE cold-climate heat pumps are evaluated through recognized certification programs such as AHRI, and eligible models can be verified through Natural Resources Canada's Eligible Cold Climate Heat Pumps list.
Before purchasing, homeowners should confirm that the specific GREE model meets the efficiency and cold-climate performance requirements for their province, particularly if they plan to apply for provincial energy-efficiency rebates. While installation quality, proper system sizing, and home insulation all influence real-world performance, certified cold-climate models are designed to provide reliable heating in Canada's harsh winter conditions.
Across the homeowner and installer feedback we've reviewed, several consistent trends emerge. Many homeowners report improved energy efficiency and quiet indoor operation, particularly when upgrading from electric baseboard heating or older HVAC systems.
Customer service experiences vary because GREE's Canadian support network is smaller than those of competitors such as Mitsubishi and Daikin, meaning warranty claims and technical support are often handled through the installing contractor or regional distributor rather than directly by GREE.
The GREE mobile app and built-in Wi-Fi features receive mixed feedback, with many users appreciating the convenience of remote control while others report occasional connectivity issues or find the app interface less intuitive than those offered by some competing brands. Overall, GREE heat pumps are widely regarded as offering a strong balance of affordability, energy efficiency, and reliable cold-climate performance for Canadian homeowners.
GREE heat pumps boast strong efficiency ratings, especially for mini-split models. Their flagship Sapphire series is to officially rated by GREE at up to 27 SEER2 and 11, HSPF2, putting it among the top performers in the. brand's residential lineup.
📌 Editorial note on the "38 SEER" figure: You may see GREE's Sapphire line advertised elsewhere with a "38 SEER" cooling efficiency claim. We were not able to verify this figure against GREE's official specification sheets or an AHRI certificate — GREE's own Sapphire brochure lists a maximum of 27 SEER2. For reference, the switch from the legacy SEER metric to SEER2 (driven by the DOE's updated M1 blower testing procedure) typically reduces a rating by only about 4–5%, not the roughly 30% gap that a 38-to-27 comparison would imply. Until a specific AHRI certificate number is available to confirm the 38 SEER claim for a specific model/capacity, we're using the AHRI-certified, manufacturer-published 27 SEER2 / 11 HSPF2 figure as the reliable number for purchasing decisions.
| Model | SEER2 Rating |
| Livo GEN4 | Up to 20 |
| Vireo GEN3 | 25.5 |
| Vireo+ Ultra | 20 |
| Sapphire | Up to 27 |
| FLEXX | Up to 17 |
| FLEXX ECO | 15.5 |
| Multi GEN2 | Up to 21 |
| Multi+ Ultra | Up to 20 |
| VRF GMV MTAC | 15 |
All major models are AHRI-certified and Energy Star® rated, which ensures verified performance under Canadian energy standards.
Indoor noise levels for GREE systems typically operate at a whisper-quiet 19 to 45 decibels, making them perfectly suited for bedrooms, offices, and family areas. Outdoor condenser units generally run around 55 to 68 decibels, depending on the specific model and installation site.
GREE systems are engineered to function in challenging Canadian climates, with an outdoor operating range of -30°C (-22°F) for heating capabilities down to -30°C and cooling operation up to 46°C (115°F) for cooling. Their patented two-stage compressor technology allows for efficient heating even during deep winter conditions.
All GREE heat pumps use R-410A refrigerant, which complies with modern environmental standards and does not deplete the ozone layer. (Note: newer Sapphire-series units are increasingly shipping with R-32 refrigerant, which has a lower global warming potential than R-410A — worth confirming refrigerant type with your model/dealer.)
A well-installed and maintained GREE system can last up to 20 years. However, factors such as climate, usage frequency, and installation quality greatly influence longevity. Annual servicing and timely filter replacements are key to maximizing lifespan.
Nearly all newer GREE models come with built-in Wi-Fi for smartphone or tablet control. The app allows temperature adjustment, scheduling, and monitoring energy use — although the user interface could use improvement.
GREE heat pumps function using a reversible refrigeration cycle, allowing them to both heat and cool your home. The system contains four main components: a compressor, condenser, expansion valve, and evaporator.
This process is energy-efficient because it transfers heat instead of generating it through combustion or electric resistance.
The cost of a GREE heat pump varies depending on size, configuration, and installation requirements. Below are general estimates for Canadian homeowners:

GET FREE QUOTESThe federal Canada Greener Homes Grant is closed to new applicants. New applications stopped being accepted in early 2024, and the final deadline for existing applicants to submit outstanding documentation was December 31, 2025. If you already applied and completed your retrofit before the cutoff, your reimbursement may still be processing — but this program is no longer an option for new heat pump purchases.
Heat pump incentives in Canada are now driven mainly at the provincial level. Programs that are currently active include:
- Ontario: Enbridge Gas's Home Efficiency Rebate Plus (HER+) program offers rebates for cold-climate air-source heat pumps for Enbridge Gas customers, alongside the newer Home Renovation Savings program (delivered with Save on Energy).
- Quebec: Hydro-Québec's LogisVert program is the main channel for heat pump incentives, covering wall-mounted, central, and multi-zone systems.
- British Columbia: CleanBC Better Homes (delivered through BC Hydro and FortisBC) offers a standard rebate stream for all homeowners, plus a larger income-qualified stream through the CleanBC Better Homes Energy Savings Program.
📌 Editorial note: Rebate amounts, eligibility rules, and program status change frequently and vary by utility territory, income tier, and equipment type. Before budgeting for a GREE heat pump purchase, verify current program availability and dollar amounts directly with a licensed local HVAC installer or the relevant provincial program administrator — don't rely on a flat rebate figure quoted in any single article, including this one.
