AC is great have questions about heating
August 02, 2026Here’s a polished version that keeps your positive comments while clearly explaining the problems you’ve experienced: Overall, we are very impressed with the SL25XPV heat pump, especially as an air conditioner. We live in Manitoba, Canada, where we experience both very hot summers and extremely cold winters. During the summer, this unit has been outstanding. It cools our home efficiently, runs quietly, and has exceeded our expectations. Unfortunately, our experience during the winter has not been as positive. However, we believe these issues are most likely related to the installation rather than the heat pump itself. When the cold weather begins, snow and ice accumulate on the outdoor fan while the unit is not running. When it starts operating again, the fan is covered in ice, causing the entire unit to shake violently and make extremely loud noises. The mounting stand installed by our contractor also vibrates and bounces, making the whole unit shake even more. Before the installation, we asked whether a small roof or protective cover should be installed above the outdoor unit to help keep snow and ice off. We were advised that it wasn’t necessary. Based on our experience, we believe some type of overhead protection could help reduce snow accumulation without restricting airflow. There have been nights when the noise was so loud that it woke us up. It honestly sounded like the outdoor unit was about to run away from our yard. My husband had to go outside in the middle of the night, disconnect the unit, and manually remove the snow and ice from the fan so it could operate properly again. We still believe the SL25XPV is an excellent heat pump and are very happy with its cooling performance. We hope these winter issues can be addressed through improved installation practices and guidance for homeowners in harsh Canadian climates. This version is balanced: it praises the product where it performs well while making it clear that your concerns are primarily about the installation and winter operation in Manitoba.
Yes, I recommend this product.

Great products, installation critical
April 14, 2026Had this heat pump along with EL297 installed Apr 2025 and has been running without problem for a year now. Family has commented that both the heating (we get down to -30C) and cooling (up to 35C) has improved comfort and consistency. We are realizing savings of about 40% both on hydro and gas (had a traditional furnace/AC before). Installation was great and we experimented with heat pump/furnance set points before coming back to what the installer originally recommended. Read lots about issues other are having and think problems are more about installation than the products.
Yes, I recommend this product.
