Bigger is not always better when it comes to air conditioning systems or heat pumps. When we talk about the size of an A/C or heat pump, we are referring to the capacity (measured in tons) it can cool down a building. Usually, the more square feet a building has, the more tons are needed on a system in order to be able to operate smoothly.
"Tons" in cooling or heat pump systems do not represent the weight of the units. In fact, tons represent the cooling capacity of air conditioning systems and the cooling and heating parts of heat pumps. Generally speaking, this means that the bigger your home, the more tons your cooling/heating system will need to cool/heat your home. Most residential cooling/heating systems range between 1 and 5 tons.
HSPF is an acronym that stands for "Heating Seasonal Performance Factor". HSPF is a rating like SEER but instead of being a rating used to measure the efficiency of a cooling system, it is a rating to measure specifically the heating efficiency of a heat pump. A heat pump has both a SEER and an HSPF rating since it can both cool and heat a building.
As mentioned in a previous blog post, SEER is an acronym which stands for Seasonal Energy Efficiency Ratio. EER on the other hand, is an acronym that stands for Energy Efficiency Ratio. Both these acronyms are used to evaluate the efficiency of a cooling system such as an air conditioner or cooling part of a heat pump. The SEER and EER values are not equivalent.
S.E.E.R is an acronym for Seasonal Energy Efficiency Ratio. SEER is a rating used to explain the efficiency of a cooling system such as an air conditioner or the cooling part of a heat pump. The higher the S.E.E.R. number, the higher the energy efficiency. The minimum S.E.E.R required in Canada for all new manufactured cooling systems is 13 SEER which was adopted back in 2009.
