Oil in 134a systems will "cook" when overheated, producing a waxy gunk. I know these aren't technical terms, but I had to discover all this on my own since the big changeover in 1993 era. This wax...

You have CO sensors around the house, they don't go off when the furnace is running so I doubt you are having HX issues. It sounds like your unconventional flue is the problem.

Thank you. My wife is happy with it.

Ditto. I still pull a few coils every year that are over 30 YO. All are aluminum.

Obviously this is a museum piece. I would have the curator call around to his other curator buddies to see if they have any Chrysler Airtemp blowers on display.

Trane Hyperions have had an issue with door switches in hot attics. There is a retro fit kit for them though. If yours is a Hyperion, you may need to get in touch with the installer.

Plus ths cost of steppin it down to single phase.

That "reality" part is what we do for a living. Californias "reality" may be a little higher than Arkansas"reality", but thanks for playin!!!!!

Federal Pacific panels::DD: there went any savings you accumulated over the years.

Steamin cow plop. That stuffs everywhere around here. Not alot of fire ant hills in limestone (hill country)

Thanks guys, I will check settings and report back.:cheers:

My 550's read 13-15# with no pressure on them. Anybody else had this problem? How do you reset them?:gah:

exactly, they are out of calibration and unreliable for those who can afford them to be.:.02:

how do all the cops and judges with dwi's get insurance??? :confused:

it could also be , that the owner had made some mistakes in his life, and somone had given him a chance.

thats what life is, getting taken to school. i have made mistakes in life, and i have hired people who have made mistakes. in the end all you can do is hope it balances out. i do agree with, you that...

geez dude, you should really relax. we get it , if you make a mistake burn in hell.

you have single stage cooling. y2 is for a second stage.

get over yourself. no body is making you purchase, use , or maintain any heating or cooling equipment. you are a toxic , corrosive sort of person.:.02:

he is right about the higher pressures in heat mode. you can go to the htalk contractor map, i think sarge is in S.A. i am in san marcos. it sounds as if you just need a new evap, times are hard in...

WINNER!!! most homes are undersized in the amount of return air. 1" pleated filters are the worst thing you can put in an undersized return.

your'e full of it robo, but that IS funny.:grin2:

they have had the plastic blower housing for years.

i think it is time to call a pro. one you trust.:.02:

yes indeed. you get what you pay for. the good news is you came to the right place to get good advice.

call me!!! i will install every part there is, for every situation.

there are surge protectors on the market, but even they can't guarantee 100% effectiveness.

is there a return in this 4 supply room?? if not, no tstat is gonna be accurate for total home comfort. he may just be dumping mass amounts of air into one room, making it warmer/cooler than the rest...

thats my local joint. ribs are good, brisket okay. really good chopped sandwich. i still say Black's in lockhart is the best all around. and they ship anywhere if you don't want to take my word for...

ditto, super tight house and way lower DP.:.02:

he is bound to love them, since his main complaint about the old handlers was everything being in the airflow. problem solved!:yes:

you can make practically anything work. making it perform requires skill.

the technology is not new. trane had a variation of it back in the late 80's. trouble was, you couldn't find many people who could work on them. i suspect that is the case with the iq. nice set up...

5 ton on a 900 sq ft room??? unless there is a blast furnace located in the middle of the room, i would get some oro advice and a load calculation.:.02:

ditto

no xc21 or xl20i in the mix???

what part of austin??

not alot of coasties out there, so nobody cares. but i'm a coastie and i care SEMPER PARATUS!!:patriot:

we installed 2 lennox xc21 sytems in a new home not long ago and they are very nice and very quiet. with both units running full blast in 105 degree heat i could hear the pool pump running over 20 ft...

don't stress about it too much. the 16i needs to be tweaked to work well in this climate. i have seen happy customers with 16i systems , but in almost every case it took some tweakin to get them that...

every bit of advice you have gotten here has been very good advice. the 16i doesn't remove humidity as well as single stage systems but CAN be set up to work very well. 350 cfm and comfort R is...

how much we bettin' ?????

well guys, since the economy tanked, how many of these nice people do you deal with every week??? and the result is always the same, no sale, no money in your pocket, and wasted time you can never...

also have him check to see if there is an old factory installed filter drier inside the cabinet. i have replaced a few compressors that were wearing two sets of drawers.

oh you know, a/c is just a button on the wall.:grin2: wakko you can find me on the contractor map or click on my user name. i might be in your area.

my advice to the OP is never ever, under any circumstances use a technician who might misdiagnose your system. and never ever use a service company that marks up a part. that should keep you from...

::grin2:i don't think they mentioned tape back then either.

"false sense of security", you said a mouthful there BT !

awww. don't tell me you liked the 3078 pound 4ftx8ft all steel air handlers!:grin2:

no question about that BT. i'm just amazed when people think they are stuck replacing a 17 year old system, especially when they know itsa 17 y.o. system.:grin2:
