Variable Speed Cooling

Variable speed (VS) cooling provides maximum comfort for your Toronto home. It is a technology that has been available for some time, but in the last 5 years has been truly embraced by HVAC manufacturers. In time, all air conditioners will become variable speed, allowing them to match cooling loads/requirements precisely. Like a modulating furnace, or the inverter technology used in ductless systems, a variable speed compressor communicates with the fan in your furnace as it changes speeds.  “Variable speed” refers to the speed at which the compressor outside, and fan portion of your furnace inside are operating – thereby controlling the flow and frequency of air that is generated - supplying cool or temperate air throughout your entire home. They run longer, usually at lower capacities, moving cool air to the far reaches of your home. Because of their longer runtimes and often slower speeds, variable speed ACs are amazing dehumidifiers. They are also very quiet and have SEER levels of 18+ - which will save money vs. traditional units. 

Unlike a single stage AC, a variable speed compressor can move in increments as small as 0.1% in a range from 30%-100% capacity; that’s 700 Stages!!!

When you decrease the temperature on your thermostat by half a degree, a single stage air conditioner turns on at full blast, often overcooling the space and not running long enough to dehumidify the air. In comparison, a variable speed compressor will come on at only a very low capacity (for example, approximately 30%) and the blower in your furnace will also move at a low speed. This means that temperature in your home rarely would be more than half a degree away from its set point, and humidity levels will always be within your defined parameters. For a higher delta, the VS compressor engages to make a more significant temperature adjustment and the fan increases its speed and air flow accordingly to ensure that cool air enters your rooms at an increased rate.  This air flow variability ensures even temperatures and an overall, more comfortable cooling solution.
