Met Joel at the Show at Sudbury Arena. Very courteous, informative, and prompt to make a home visit. We bought an air filter to install on the furnace and a UV light with a 5" filter. Installers were pleasant, respectful of my home, knowledgeable. Only thing: a thousand lashes for forgetting to plug the hot water heater in before leaving...hubby doesn't like cold showers in the morning!🤪😂
