Today is the first of the month, so I want to say something I've said many times before and you could be, you could be tired of hearing it. The number one thing you can do for heating and air conditioning, energy bills, operation, performance, you can do it yourself. And it's as easy as changing your air filter. So simple, yet so hard to remember. I've told people before if you need to set an alarm on your phone every 30 days to check or change your filter, whatever you need to do, it is important to check and change your filter every 30 days.

This Star Spotlight features Derek Cole of One Hour Heating and Air Conditioning. Today Derek explains why it's so important to properly seal your new ductwork. Derek, welcome back. Why is it so important for us to seal new ductwork? I mean, it's new ductwork. And are there regulations or specifications that are unique to North Carolina?
Anytime in this state, you install a new duct system, you have to do. And Caroline knows this because she's now doing permits, do what's called a duct test or a duct blaster, as we call it. You have to measure how much leakage is in that new duct system. And there is a point, depending on the city, of the municipality as to what they want to see. 5, 10% of leakage they want. So let's go with the round number. I say it's 10% leakage. So you're leaking 10% of the energy you're paying for out of that new duct system. So if you seal it, it can get down to zero. Right? So if you get to zero, that's obviously more efficient than losing 10. Right. So that is why you want to seal the new duct system. Now, in this area, we see a lot of duct board, fiberglass duct system. Again, that is better for your lungs, better for your health. So we go back and we install metal duct. That way you're not breathing in the fiberglass any longer. The downside to installing that metal duct is that you have joints. And no matter how much you try to seal it manually on the way there, you seal it, seal the joints on the outside with mastic, you seal it up with tape, you seal it up with insulation. You seal that up on top of the masking tape. Still you're at 10% leakage because there is no way a human being can actually seal all the places that air flows. Now, with duct sealing, with air seal, it works on pressure. There is not. It's aerosol. There's not a human being, you know, putting mastic and painting it on the little joints. No, it's a machine. It's all controlled by this aerosol. Aerosol spray. It's working on pressure and it's filling the holes as it finds the leaks.
