Campbell Industries Ltd. As business grew, so did our staff and our need for more room, and in 1998 we moved to our newly constructed Ladner location, which served us well until 2009 when the more-than-doubling of our service truck fleet necessitated a move to the current location in Tilbury. This gave us more room and better logistical positioning for our expanding role as a service provider in the Lower Mainland. With the heating and air conditioning replacement division becoming a major part of our business, and the addition of air conditioning to the plumbing and heating service department, it became apparent that the existing company name did not accurately reflect all that we had become.
