Windsor, ON

I have never had such a pleasurable experience with POS in Windsor. The technicians were courteous, professional, and a pleasure to work with.

We have used Ontario professional services for many years for heating and now plumbing. They set up appointments promptly, show up when they are supposed to, and do excellent work. I would highly recommend POS!
