Two to five times worse
Chapters
And things start to grow and things need attention. And with the indoor air quality or with your duct system or your unit, we can handle all those things. And when you have all this coming together, it can make for quite a messy soup in the house.
A messy soup. I like that. That sounds like the name of a band or something. So what do you do about that? How do you address that problem?
Mainly when it's inside of the unit or the duct system? We can have that with UV lights. It's something that a lot of folks don't really think about because, you know, it's not day to day like it is for us. But UV is. Is a powerful product. I mean, it's the sun. You're basically bringing the sun inside your system, which is in a damp, dark spot. I mean, when you think about it, you got hot air coming across a coil, which is then cooling the air down and then dripping and then things in the pan. It's dark, it's damp, there is no sunlight. Things start to happen. That's pretty nasty. UV can handle that problem. So if you, you know, if you think about the north side of a house or if you're in the woods, the north side of a tree has moss on it.
Right.
That's because it gets no uv. Things start to grow. Right. So we can take that same power and put it inside your cell system.
Okay. So that's something to look into. Just one of the many problems that you can run into.
Yeah.
With any standard H VAC system.
Yeah. I mean, the. The EPA says indoor air is two to five times worse than outdoor air.
Wow.
We're living in chemical soup, which are, you know, paints, lacquers, chemicals. I mean, all this stuff is in the house. And we can fix that. We can handle it with UV and ozone and products that's natural in the environment that we can bring into the house. So you're basically breathing the air you're breathing outside.
So in other words, if there are people out there and they've got questions like this, and that's one thing I found out about you. You like to. You like, you're almost like a H Vac doctor. I don't know.
Right, right.
But you guys really are. It seems like that that's something that you guys specialize in, is diagnosing and treating the specific problem.
Exactly. I mean, one thing that I've been on recently is a lot of other professions or companies offer band aids. We offer cures. You know, that stuff is growing, but instead of cleaning it off and just ignoring it. Let's see what the cause is. So let's get to the problem. Let's not just band aid it.
