During my many years of getting furnace inspections, this visit by Tariq was by far my most detailed, productive and explanatory experience. Tariq is a total professional, starting with his very pleasant and patient demeanour leading to his thorough diagnosis and prognosis for our furnace and ending with a complete explanation with visuals and insights. I greatly appreciated his attention to all dimensions of furnace operation. He never tired from my many questions and I greatly appreciated that !! I highly recommend his services...
