Thanks for the advice. Energy Rater and MEH, I will email you separately for recommendations. After reading your replies and stewing on it, I definitely want to get it repaired and at least buy...

I've been playing phone tag with the design guy so I'm guessing based on what the tech said that it would be a whole new system including the furnace. Sorry for the confusion, by prof I meant...

I finally got an HVAC pro out to do annual maintenance and look at my system. (I went on Angie's list to find them.) The tech said that the evaporator coils (in attic) were filthy and plugged up...

Are doing/checking all of those things generally considered 'standard' when getting annual maintenance?

Don't worry. I'll caulk and even re-seal loose ducts, but I have no illusions about doing...

Forgive all the details. My question is pretty straightforward I think but the background may help. In another thread, I had mentioned that the blower motor on my ac had gone out several years in a...

I think I get what your saying, but some it going over my head. I read the section from the train article, but it's late so I'll probably have to reread it tomorrow before I fully get it.

I've...

It's been a couple of weeks so I thought I'd give everyone an update. I'm also hoping it can show other homeowners what's possible!

I re-routed the ducts to the back of the house which allowed...

Update:
During the first 16 days of this billing cycle, I was using on average 107 kWhrs per day. Typically, I set the t-stat to 78 or 79 before leaving the house for work (I have pets).

Today,...

tedkidd, thanks! I take that as a compliment. I don't know if I have another career change in me, but you never know. Maybe I could barter a blower door test for some weekend helper work?? ;) I...

I checked out the mystery duct. It was attached to a register, but it is sheet-rocked over. That bath has been fine without a vent (door usually open to hallway) so I went ahead and capped it on...

I think the plumber caught grief from my general contractor for a while. I was just relieved because initially I thought I had some tropical disease that raised my core body temp to 106!!:p

I...

Off topic, but speaking of plumbers, one day I'll tell y'all about the plumber who ran the hot water to my toilet! :eek2:

Thanks everyone for the information. It is helping a lot!

I went back up to the attic to figure out which rooms each drop was feeding. (I also pulled the fiberglass back from the furnace.) ...

Thanks energy_rater_La

Here are some of the other pictures from the attic. I tried to put some notes on them to help. It was definitely warmer up there today. Maybe there had been an...

I tried to view the pic to see if it displayed properly and couldn't get it to come up. Am I doing something wrong or does it just have to be reviewed before displaying?

Is this as big a problem as I think it is?? It's a picture of the return air cavity, with the wall open to the attic. While, from what I can see, the top of the wall cavities are topped with a...

tedkid, I just noticed the link to the article about attic venting. I'll give it a read. Thanks

Thanks for the replies.

Heatingman:

The return vent is below my sight line. The cut-out starts maybe an inch or two above the baseboard. The broken ducts that I see are not return ducts. ...

I'm new here and trying to figure out how to deal with some long standing issues with my central air system. Here are some details:

Old home (prob built around 1920's) but major renovation in...
