Sentry Energy builds high-efficiency inverter heat pumps and air conditioners engineered for Canadian climates — heating reliably down to −36 °C, cooling through +54 °C, and backed by a registered 12-year warranty.
A Sentry Energy heat pump replaces both your furnace and air conditioner with a single, ultra-efficient system. It moves heat instead of burning fuel — keeping you warm in winter, cool in summer, and lowering your energy bills all year.
Variable-speed inverter compressors ramp output up and down to match demand exactly — up to 20 SEER2 cooling and 9.5 HSPF2 heating, with no energy-wasting on/off cycling.
Our UltraHeat models deliver dependable heating down to −36 °C, so you stay comfortable through the harshest Canadian winters without a backup furnace.
Every unit ships with a standard 7-year parts & compressor warranty, extendable to a registered 12-year warranty for total peace of mind.
From a single-room 1-ton mini-split to a whole-home 4-ton system, every Sentry Energy unit shares the same DNA: inverter efficiency, R-32 refrigerant, and Energy Star performance.
Every Sentry Energy system runs on R-32 — a next-generation refrigerant with roughly one-third the global-warming potential of older R-410A, zero ozone depletion, and higher energy efficiency.
Sentry Energy systems are sold and supported by Legacy Heating & Cooling — a trusted Canadian HVAC supplier and proud partner of the Edmonton Oilers.
