Could I ask a favor.

Please break you messages up into paragraphs.

Having it all in one my it makes it hard to read. My eyes keep loosing the line.

Lots of white space makes it much easier...

I would not recommend that to some one that is not very, very experienced. It can be dangerous in several ways.

Really need a clamp on. And you can get clamp on adapter that put out so many...

It depends.

You already know that the existing system is not giving you great comfort. A better furnace system, might help that. Might also need some duct work.

And you know what your current...

I noticed that my new 2 stage AC/HP show two different sets of number and eff for operating in stage 2 HP.

And they are based on 2 different air flows. I am assuming that the purpose of the lower...

I did not see any mention of RETURNS.

I am a HO with an engineering background. From what I have experienced in my own home and others and complaints of people 2 story houses the having returns on...

Not always.

The are a number of different types of ground electrodes, some installed for that purpose and some for other purposes that if available MUST be used.

Under the current code;

1....

There is lots of cost factors, plus lots of politics, that get into setting the rates.

Idealy you should have a fixed cost that pays for billing, meter reading and the like.

And a base rate...

IR won't always show the problem. An other test is to measure the current in the ground electrode system.

PS an open would be very unusual. And in that case it would be immediately clear with...

Define "tightly built". Exactly how many air changes per hour is that.

You have already defined one place that was not "tight".

The only way that you will know for sure is to get an energy...

As a non pro that sounds the first thing that should be checked.

Also what about setting the programable stat to let the temp rise in the early more and not even use the heat mode.

The tax credit is only on the materials, not the labor. Make sure that you get the statement to break that out.

Maybe that short a payback AFTER the rebates and credits. But even then I suspect a...

If I remember this thread over the weekend I will tell you what mine is set to.

And I am going to talk to the installer about some of the options.

I have really know thought about the AC...

It doesn't require high levels.

"Carbon monoxide is a colorless, odorless, tasteless gas that, in its effects on humans, is a chemical...

Do forget my idea of getting a whole house surge protector and verifying the ground electrode system. It should not be too expensive. Some power companies provide them for a $5-8/month fee and also...

There can be lots of affects of CO posion at levels much lower than the alarm point.

Because of 2 many (possible) false alarms they uped the alarm limits.

If you get a have one with a digital...

What is "less restrictions" ??

I agree with your thoughts. I am Kansas city and while the numbers will change somewhat the most except for the top row or two or states and the bottom row that is a...

I am looking at the data for the 18 SEER, 2 stage York that I am getting.

http://www.yorkupg.com/PDFFiles/345094-YTG-F-0509.pdf

For the AC they show the 2 stage of compressor and corresponding...

I am not sure who this was directed to. Because I said nothing about HD.

The rules are no price quoting on the forum.

But the York rebate is $1700 and Federal Tax credit of $1500 for a total of...

No, runing on low speed for the AC is good for you. Both in comfort level (lower humidity and more constant temps) and lower energy usage.

And that is exactly what I am getting.

Normally I could not justifiy the pay back on such a system.

But with the package system rebate from the manufacture and tax credit and gas company rebate...

I knowing about the details of the Carrier control boards only basic understanding of the HVAC systems in general.

But I have designed control board with microprocessors for industrial purposes....

In an application like this it is probably a wash. Few extra parts and they are all basic chips that have been commonly used for years and years and are very reliable.

In commercial/industrial...

Ok.

I had to google TXV. Almost the same problem that I though it was.

Their appears to a fat bulb that is 1/2 under the insulation that is kinda, almost, sorta, maybe having contact with the...

I gather that the blue tip is the senors bulb. If so I can see the problem, in spades.

And in fact I don't know why the other 2 tech for the new company (if I followed the story line) fix it.
...

Could you briefly expand what is wrong with the TEV except it looks like a messy install?

And are TEV and TXV the same things?

Thanks Bill.

Serial just means that a large amount of information is broken down and transmitted one bit at a time. Parallel means that each bit of information (function in this case) is set at the same time...

It is possible that this has nothing to do with the AC.

What else happens when it is 100.

All of your neighbors AC's are running also.

It could be a voltage supply problem or partial low...

Absolutely not.

Check on BIBS - blow in blanket system. That is used for insulation walls.

But the material is in attics is similar. And in this area one of the home horror chains is selling FG...

Lots of variables that have nothing to do with capacity of the system.

If the house was unoccupied the AC might have been off upto 1/2 hour before the open house.

And I don't know how many...

No help on your questions. But read the HW contract and see what it say about heating and cooling.

And if you are not sure what it says hire an attorney to review it. NO TO SUE, but just to...

A cheaper mechanical stat the switch pivots are just rivets and they are also the electrical connection.

I had one where the heat/coil switch did that.

Look at the model number of the compressor. Most of them that I have seen have the tonage as part of the number.

They usually have a: 12 for 1 ton, 24, for 2, 30 for 2.5

If you go with some of...

I have gotten into a several discussion about how solar is no good for reducing peak load without lots of storage.

I did not find lots of data, but found several POCO's that had charts or tables...

Interesting to see the changes over the years.


Right now our gas is 0.54/CCF.

Besides gas purchase gas cost being down the rates where restructured cost of operating the local distribution...

Why?

I know that you might feel a HP is not appropriate for your situation and you might be right.

But as I am learning that with the rebates and credits and with the what features are only...

Was looking that the York Humidifier flier.

And those this amazing discover.

You need a score card to keep them straight. The two dealers that I have been working with both had some of the details wrong. And I had some miss-understandings that they clarified and I am not sure...

No good.

The POU is point of use unit. It is for an isolated kitchen or 1/2 bath where it is too far to run hot water. Often used in offices and the like.

You don't want to take a long shower...

You need to get REAL quotes. And find out what qualifies for federal tax vredits (and if your taxes are such that you can take advantage of them). Any manufactures rebates, any state rebates/credits,...

One of my neighbors is in for an expensive surprisse.

Working outside monday and tuesday and kept hearing a 2 second HUM about every 5 - 10 minutes.

Between the lake and the hill you I could...

I have gotten a couple of proposals for a replacement system.

And I am thinking about dual fuel, vs straight AC and NG.

And I am trying to figure out what percent of my heating can come from a...

I hate to say it, but I am a HO and when I call I tell them that it is low on freon.

And that is because there is a known leak. And when I call it has frozen up. A number of techs had ID the...

S/N 2578A 00633

Those dates look right. The house was started around Oct 78 and I moved in March 79

I am looking at replacing my old AC and furnaces and was trying to figure out what the SEER was on the AC. In the back of my mind I was thinking it was 10, but really don't remember.

Tried looking...

This sounds like a good application for some Peltier (Thermoelectric) devices.

Don't know what the rating are on those.

There is a Peltier based CPU cooler, which is really the most critical...

No neither the UMC or the NEC are required everywhere.

A number of states don't have statewide codes or have them for only one or 2 trades.

MO and KS are two. Now most of the larger cities and...

Clearly a bad install. The flue and gas drip leg running horizontal <G>.

Don't know enough about HVAC installs to give a general comment. But much of the electrical work leaves much to be desired,...

Is a TXV valve on the outdoor coil just as import (or more so) for heatpump mode?

I would assume so as the heat pump mode needs to operate over a much wider range of conditions (20-70 degrees)...

I will have to talk to some of the fisherman to see if they know what how the thermoclime runs.

Upper water gets about 80.

I am beginning to see that unless I can get deep enough to where I can...
