You can hurt your HVAC unit by closing off the air vents too often

I used to have to drive almost 3 hours a morning, 5 mornings a week, so I got into something that’s called hyper-miling, which means using every trick in the book to get the most out of your gas mileage with every gallon of gas.

If your automobile gets 25 miles to the gallon, you try to get 30. In my case, I was able to almost double the mileage our automobile was supposed to be getting. It took a lot of work, but I liked it. And ever since this lockdown started, I haven’t been driving anywhere! While I don’t miss it, I do miss the challenge of hyper-miling, for some reason. Now I’ve turned that focus to our Heating, Ventilation, plus A/C system. It is really hot around here this time of year, and since I’m at home most of the time I run our A/C way more than I ever had to before. Now I am doing a Heating, Ventilation, and A/C version of hyper-miling, and I’m trying to get every last bit of cooling I can get for the least amount of cash. First, I close our blinds and then I put lots of curtains over the top of the blinds in order to trap the cooling inside. Heat transfer through windows is pretty bad, since they don’t have the insulation of walls and ceilings. Heat transfer is the biggest enemy of cooling. Once in a while, I hole up in my room, and then I close off the air vents to the rest of the house, too. All of the cooling gets channeled in here with me… This works really well for short bursts of time, but I am told that doing it can be bad for your HVAC system after a while.
