Crowley installed pool heater a year and half ago. Heater installation inspected by Enbridge 2 times over past 6 months. Three violations of the Canada Safety Code were found and the heater has been disconnected and the gas line capped. Crowley has not fixed the installation problems associated with the violations Rather he wants to rip everything out and refund my money, leaving me, if I want a heater, to bear the inflated installation costs as well as costs to fix violations. Warning. Don't use this company!
