Does it actually terminate in the duct or just run through it. (bad enough)
Just a homeowner here. But the obvious question is did they manage to damage your return ducts in such a way you are pulling in gunk from the attic? I use 4 inch media filters and can easily go six...
I haven't read all the posts here. Everybody's talking about costs. The real issue is comfort. Here in California, we have low humidity and cool nights even on the hotest days. If you leave your...
We need a professional to comment on this, I'm just a homeowner, but what about a hydronic loop of a few baseboards fed from the water heater? Since you have a crawlspace below there is plenty of...
suggesting you leave it on.
Because then you will maximize the amount of heat that is efficiently produced by the heat pump, and use less resistance heat. Well at least if the temp is above 25. ...
I'm just a homeower here in California. But nobody seems to want to be very helpful so I thought I'd share my 2 cents. I have bought numerous systems for homes I've owned but have not had a PTAC...
I live here in San Jose too. What you do have to realize that in a mild climate, while the steady state needs to keep your house warm might be slight, if you want to turn the temp down...
Why not move the thermostat?
An open upstairs hall will always be a little warmer.
If you want/ need to cool the hall more you need to add a supply
duct. But you still probably want to move the...
The vast majority of water heaters in my neighborhood which was built in the mid- 60's are in interior closets. When I said vented, I didn't me the flue.
The flues go up through the roof. But they...
I was aware of ovens
not having safety devices. Since kitchens tend to be frequently occupied, a pilot
that's out would be discovered quickly. But furnaces and water heaters are put

I'm not in the trade.
It just shocks me that any furnace would not have a safety device that
shuts the pilot...
You've got to be kidding.
I'm not in the trade, but have seen a lot of gas appliances in
my life. Never saw a pilot light without a thermocouple and the
need to hold the button down when...

But your question is simple enough.

Thanks for the quick reply.
I hope you are doing something for the 4th today.

Been There, I would like your opinion on a similiar possible code

I know the pros on this board all are in the business of central A/C.
I have central A/C now, but have lived in a number of homes that
were made quite habitable by a couple of window units. ...
They say it saves the same as carpooling once per week.

You say that I turned the green movement into how much I can save on my electric bill.
I think Lennox turned the good intentions of people who want to be green into how much money they can make on...
without a fan, not evaporator.
You can see I'm not a HVAC guy.
One quick formula (sorry):
2.2kW grid-tie system - does it...
They say that they offset carbon - but compared to what?
An evaporator without a fan? A SEER 8 system?
They want you to spend $3 to $4k for something that generates
190 watts only when the A/C...
carlb23 I agree entirely with your technical assessment.
Its a clever marketing trick to appeal to the do-good or be

I'm here in the Bay Area, but lived in L. A. years ago.
L.A. can flirt with frost, but just barely. I don't think anything in an attic
in L.A. has any danger of freezing.
Very Dangerous Situation
The sounds you are getting may be from condensation inside your walls!

Get a contractor to replace your B-vent!
But the Home Channel did do a show where exactly the kind of noise
you had was solved by replacing the B-Vent. Because the B-vent
was touching framing...
My B-vent was packed tight with cellulose insulation due to stupid
insulation contractors putting in additional attic insulation. I openned
the whole thing up and replaced it,...
Undersize trunk lines in comparison to the branches.
In the East with your long 6 inch branches you don't see the issue as
badly. But in AZ with the short and large branches the problem gets
Sorry for posting.
I posted before I read all the posts and realized how nasty agostinid had gotten.
But having lived in AZ I think I understand his issue. My house in AZ had

But you were out of line with Udarrel, if you read more than 3 posts on this
board they all all talking about heat gain calculations the pro's call...
I'm a EE. If I did this I'd build my own stat from scratch.
Though if you want to do it on a time of day basis I think git-to-run's
suggestion is right, you just need a relay that switches from...
I was looking at it the other direction.
That is if the temperature is cold out, locking out the
first stage, and going straight to second.
This is based on the concept, advanced by you and...
I'm impressed by Option 3 in concept at least.
Others on this board have alledged that two stage units are less
efficient in stage one than two. If they are right and a stage two cycle will

If he had a Phd in Physics the kid could be right. However speaking as a guy

The idea that the wire has to be made smaller is ridiculous.
Dropping the breaker/ and fuse sizes to protect the equipment may
be necessary. There is no upper constraint on the wire size, it
A forty five degree temperature rise is perfectly normal for
a gas furnace. Heat pumps would be nothing like that.
I'm a EE. I have exercised great restraint. I've kept myself from
designing my own thermostat system with multiple selectable remote sensors.
Even thought it drives me nuts that conventional...
I've posted this here before.
The official Berkeley labs study found that the only
advantage of two stage furnaces was the reduced
electricity use because of the lower blower speed.
I've actually looked for such a switch, without sucess.
Any idea where I might find one?
I used to have some pretty weird stuff I'd concocted in homes I owned.
Since I always had to...
My rule is never sue anyone if its less than $10,000.
I've eaten some bad stuff from contractors, but I'm convinced
that's the smart thing to do.
I'm sure you can have a smaller unit put in...

You had mentioned that on another thread, and that was
