Shaun and his intern, Mike, carried out the routine maintenance on our furnace for Peel Heating. They were prompt, professional and very thorough in cleaning the unit, making adjustments, and replacing necessary filters. Shaun was excellent in explaining what he was doing and even fixed a problem caused by sloppy installation of the unit. (The furnace was NOT installed by Peel Heating.) We will continue to have Peel Heating service our furnace and air conditioning units for a smooth running future.
