AC installation clarified in Alberta

June 14, 2018

In May, the government of Alberta issued an information bulletin (Standata 14-BCI-021) clarifying the regulatory and code requirements for air conditioners and heat pumps in that province.

According to an advisory issued by HRAI, code in that province specified a minimum efficiency level for ACs and HPs of 14.5 SEER and 11.5 EER as of November 1, 2016. At the time of that coming into effect, HRAI received guidance from the Public Safety Division of Alberta Municipal Affairs explaining that existing buildings would not be affected by the revised efficiency performance levels, meaning that homeowners who wished to add an AC or HP unit would have to conform to the performance levels listed in the federal Energy Efficiency Act, and not the new 14.5 SEER and 11.5 EER levels.

In the recently issued Standata, the Alberta government outlined its interpretation allowing for the installation of split-system air-conditioners in existing houses whose building permit was issued before November 1, 2016, without having to meet the 14.5 SEER and 11.5 EER performance requirements, the one caveat being that the energy performance of existing building must not be decreased with the installation of the new equipment.
