We help homeowners throughout Grande Prairie stay cool and in control with new Lennox systems that meet both comfort and environmental standards. That includes offering models with A2L refrigerants (R-454B & R-32) that align with international climate agreements.
As part of the Montreal Protocol, an international environmental agreement dating back to 1987, traditional refrigerants like R-410A are being phased out due to their environmental impact. While there is no official date yet for Alberta, Lennox is already leading the transition with the Elite and Signature Series units, as well as select heat pumps, now available with A2L refrigerants that have lower global warming potential and zero ozone depletion.
LSM stays ahead of regulations to ensure your new cooling system is efficient, safe, and future-ready.
