Thank you for the swift response and I do agree. Generally speaking, I always do load calculations. In this case, however; I was specifically told to replace the systems with "exactly" what was...

Hi all. I work for a large Carrier dealer in Alabama. I have a builder that has taken on a fire damage job and I need a little help to determine exactly what I am looking at. A lot of the information...

As for using flex duct in a crawl space aplication, I would suggest against it. It doesn't hold up well. In attics, I tend to be a little more forgiving of it if it is only used on the branch duct....

I guess I should add to my previous post. I'm not saying this is a bad product and I do think it will have some applications where it will be put to good use. I would imagine it would take 70 or more...

It should also be noted that the Lennox Humiditrol requires a variable speed blower. I'm sure it would work with a single speed blower, but have no way to know how much capacity would be lost. It...

If you must install a humidifier make it the "Skuttle Steam Humidifier" that has a drain. You do not want the pad type or the spray type that allow water to hang around when not in use. You will end...

My concerns with RH are going to be more of an issue in the summer months. I'm in a hot humid climate, and have to deal the raised humidity in the summer months a bit more than you probably do in NJ....

The Lifebreath TFP is a fantastic unit. My concern with a 2 floor stand alone installation is this: I would be concerned about the length of the supply runs as you will only have approximately 220...

question.

It's been a while since I took any psychometrics courses. I need a couple of things from you guys, if you don't mind. First, I'll give you the scenario that I need help with.

Ok,...

You probably did not have DSS if UV worked. As I mentioned above, I think DSS is a bacterial issue, not fungal. It will need to be abated in a different manner. You would think this problem wouldn't...

I use the Air Advice monitor often. It is a great tool that can alert you to potential IAQ problems in a stucture. While it is simply measuring particulate and not distinguishing between pollen, dust...

Hey guys, I've been away for awhile. Teddybear is right, your new system and ductwork could become just as stinky as the old one within a couple of years. The way to correct any odor problem is to...

I think you do need to get a specialists out there. One thing to note....When you're A/C is running, you are dehumidifying in the living area. The more you run it, the more moisture you remove from...

Your return is a little undersized for a 2.5 ton. It should be a 20 x 25 or 200 square inches per ton. Not good for the system as it cause undue stress on the equipment. The small leaks found in the...

It also depends on the HVAC equipment. Some controls simply bring on the A/C when called for dehumidification without doing anything to control the speed of the variable speed fan.

As for cleaning the air the best and most effective air cleaner I have found is the Lifebreath TFP by Nutech. A really good wholehouse filtration system that uses a newly designed pre-filter before a...

Since it will not let me post an email addy, just call my office at 256-381-7195.

Thanks,

Wifelet...I am about an hour away from you. If you will drop me an email at [no email addresses] I will be glad to give you a cellular telephone number that you can reach me through. I have worked in...

What part of North Alabama are you in?

Thanks,
Parker

LOL...yes it is my friend.

This is something my boss is making me do that is going into the newspaper. I don't think he was looking for that short of an answer, although it is obviously true.

I have to answer the following question. That in itself is not a problem. The problem I have is that the question must be answered in less than 100 words. I'm having a hard time doing it in short...

What kind of dehumidifier did you put in your crawl space?

Options,
Notice that I said both the negative pressure machine as well as the rotobrush need to be used. I think the 2 machines actually compliment each other very well. Visual inspection is key. ...

No, you're exactly right. I didn't mean it to come out that way. I guess you can tell from all of the typing errors that I was in a hurry.

The point I was trying to make is that the fan should...

The chicken or the egg? This is a very interesting thread and due to time limitations ( I should be working) I must make this post short, but there is one thing I wanted to get out there and I will...

While I disagree with a lot of the editorial posted above, I do agree that he has some relevant points. I do not personally perform duct cleaning as a service, but do see where the need is often...

Also being from a hot-humid climate (Alabama)I often run into cases similiar to yours. I agree with most everything that has been mentioned previously, but would like to take a moment to point out to...

On the UV light subject. I think some UV lights are pointless in that they lose their intensity in lower temperatures. Most UV lights on the market fall into this category. That said, I bought a...

As already alluded to, fans in the crawl space pull a negative pressure on the living area (worse in some houses than in others). This can cause a rise in humidity in the living area when the AC is...

Again I agree with airman. The thermastor can work in both areas by ducting it into bothe the crawl and the supply of the HVAC system. If you are going to take this approach, I highly recommend that...

I agree with the previous poster 100%. The Thermastor Ultra-aire unit is great.
