Owners Jamie and Anna Donaldson, have worked in various fields. Jamie worked in many trades and built the business up from a shed in their own backyard to what it is today. As we continue to grow and reach surrounding communities, Jamie and Anna plan to expand into more services outside of heating and cooling. Anna Donaldson, an original Londoner, reflects on Donaldson as a company but, also as local people saying,

“One of our founding principles of Donaldson Heating and Air Conditioning is to be able to give back and support the community that we all call Home“.

From sponsoring movies in the park, participating in the Santa Claus Parade, donating to silent auctions, and assisting with the initiative to provide AED’s in our schools, it has always been an important component of what we do. In 2015, Jamie and Anna’s son Zander, was born 12 weeks early which led to an 81 day stay in NICU where they came out of the experience wanting to help other families through similar experiences therefore Donaldson Heating and Air Conditioning has most recently partnered with the Children’s Health Foundation to support the London NICU where a portion of our February sales is donated to help newborns at risk successfully enter our world healthy and happy.
