Community Service

Besides offering quality HVAC services, Northern HVAC Co. has built a strong relationship with the locals by giving back to the community. 3 years ago, when Kieran Gillooly was seriously injured, the community came together to assist him and his family. He donated a lot of time to complete the installation of heaters for a local Youth Community Hub Centre. Additionally, he worked hard to cut the cost from the supplier for donated materials. During Christmas, Northern HVAC Co. gave away two turkeys to two local families in need. Recently, our owner saved a Great Horned Owl.


Kieran has also helped the residents of Ottawa by providing helpful tips and suggestions regarding “what to find in a heating contractor.”
