Just in time for the summer months, the air conditioning industry has shown an increase in residential applications. According to the Heating, Refrigeration, and Air Conditioning Institute of Canada (HRAI), the first quarter of 2021 posted the largest increase in residential air conditioning year-to-date—up 135 per cent, to be exact.
This is followed by ductless split systems (up 74 per cent), residential furnace (up 71 per cent), unit heaters (up 59 per cent), commercial air conditioning (up four per cent), and chillers (up four per cent). Air handler units showed a decrease of eight per cent in the number of shipments.
For the purpose of this study, residential air conditioning means ducted split system air conditioning and heat pumps up to five tons; ductless splits means heat pumps and conditioning condensing units (cooling only); commercial air conditioning means rooftops (combination heat/cool), packaged cooling and packaged heat pumps; furnace means residential forced air furnaces of all types (gas, oil, electric and combination); chillers include large tonnage liquid, reciprocating liquid and absorption chillers; unit heater means self-contained automatically controlled vented units limited to heating of non-residential space and duct furnaces; air handling unit means a device used to condition and circulate air containing a blower, filter, sound attenuators and dampers.
Minor adjustments were made to the 2020 quarterly and year-to-date studies for the residential market air conditioning and year-to-date for ductless split systems.
