When I was talking to the HVAC specialist about our new HVAC system, 1 question he asked was if I wanted the air vents up high or down low? I couldn’t suppose he would ask such a question? I wasn’t the HVAC specialist, and I thought they could make that decision without me, however he was serious. When he explained about the way heat and freezing reacted, I felt savor I was back in university getting a math lesson. His question about knowing what it would cost to have the air vents and returns in weird spots threw me off guard. I was paying for this new HVAC system. I wanted everything to be perfect, and I didn’t want a bevy of heat and freezing floating around our condo where it couldn’t be used, because I was worried about a few hundred dollars. He apologized to me, however said it was a bit too late to add extra air vents without adding more HVAC duct. He told me that the small fans inside the HVAC duct would direct the cool air and heat to where it needed to go. When I changed from heating to cooling, the fans would change their direction and it would automatically send the air to the floor or the ceilings. I thanked him for his explanation and said I didn’t understand what the fans were for, after a lengthy discussion about the air vents and how the smart thermostat worked, I was pleased with the work they did. I only wished I had the new HVAC system installed a couple of years earlier.
