Thank You all for the support. The reading was taken on his gauge set at the condensor to answer one of the questions. He told me that 6 degrees subcooling was good for the day that he came out which...

Do I need to call the tech back out and have him service it up to 10 degrees sub-cooling or is 6 ok?

I'm a home owner and I added my email address to my profile. Thank You

Shouldn't it be 10? Shouldn't my unit fall under 1448 for a 4 ton? I'm new to this and don't know. I just want to have everything straight when I call them back tomorrow. Thanks

I have a 4 ton Rudd system with a TXV. Can someone tell me if my subcooling should be at 10 when it's 95 degrees out? I just want to make sure I'm reading this correctly. The tech came out and the...

Beenthere,

The outside temp has been about 92 degrees or so. I still keep the stat at 78 degrees. It has been wierd weather here because we have had some cooler days with overcast. But for the...

Hello All,

I got my new thermostat installed. I have noticed my night time run times go from 3-5 minutes up to 12-15 minutes when it is dark and about 78 degrees outside. I really haven't had a...

Thanks Guys for all the info. I'm having a new stat put in on monday. I'm also leaning towards buying the 10 year parts and labor warranty.

I believe the load calc is correct it could have gone either way with a 4 ton or a 3.5 ton. Well I checked my run times when I woke up this morning. It was 71 degrees outside the stat was set to 75...

I will keep track tonight and early tomorrow morning before I go to work. So you guys think the run times will be back down to a couple of minutes tonight or early tomorrow morning? Thanks Again
...

Ok since I have lowered the stat to 75 degrees. It took about a hour and a half to reach that point. Since then it has ran 25 minutes on 7 minutes off 20 minutes on 9 minutes off and right now i'm at...

Thanks Guys they are coming to change the stat on monday. Thanks for the info on the 5 ton coil. That makes me feel better that has nothing to do with it. I spoke with one of the installers and they...

Thanks Guys for all the info. I just got off the phone with one of the installers that I perfer to talk to. He said that I might have a 5 ton coil upstairs in the attic with the furnace would this...

The stat is mounted next to one of the return ducts. No supply air is hitting it. The hole for the wires have been sealed. As far as height I would say 4-5 feet I think with out measuring

Thanks for the info. I just read through the manual and didn't really see anything except for it cooling 3 degrees below the set point if the humidity is to high.

Is it possible for the stat to be deffective???

Ok i'm back I had to go do some work. To answer some questions I live in Little Rock Arkansas. I have a family 400 American Standard stat with a allegiance AS 14 outside unit with comfort R 4 ton....

I'm trying to cool the house not heat it. It will get up to 93 degrees here today. We just keep our stat set at 78 degrees. It gets down to the low 70's at night

The temp this morning was 72 degrees outside with 78% humididty and my stat is set at 78-79 degrees.

Yes I have a 1 year warranty with the system and house. They have been out 3 times now and keep saying nothing is wrong with the unit. They have checked pressures and temps and freon levels. They...

2 month old 4 ton system.

I have been so busy that I really haven't had time to check my on times with my ac. Well this morning it ran for 1 minute on like 50 off 2 minutes on and 30 off and 4 on with 30 off and 5 on with 30...

I ordered a new stat and it will be here next week. Would you guys recommend me to get another load calc done? If I do require a 3.5 ton how should I approach the installers to let them know that I...

Beenthere,

I wouldn't say that i'm satisfied. I just want my system to run like it's suppose to. The installer is telling me that everything is fine with the system. I'm sure that he doesn't...

I'm sorry let me restate something. Since I have turned my cooling droop function off and turned my fan to auto instead on running cont. My run times are still kind of short 5-15 minutes being the...

I just got the summary

The load calc came out to 3.75 tons. So is this 4 ton to big or just a little oversized? Thanks again for all the info.

So they should do one for both? Also would it be possible to need a 3 ton ac system and a 4 ton furnace? Or could that even happen?

Thanks. I will check all the paper work when I get home. So do they do a load for heating a house and what would that be called? Thanks

I have a question about load cals. My installer dropped off a heat load cal to my wife this morning. Is there a cooling cal that should have been done as well? I have not even seen the paper yet. My...

I was wondering if anyone had used one of the 2 stats that i'm looking at buying. There's a pretty big price diffrence I was just wondering if it was worth it or not. Thanks for any replys

beenthere,

The boss of the AC company will be in monday. They were going to check the heat load when he gets back. So does that mean they only did a heat load? Have you heard of them doing that...

I was just wanting to know if anyone was using this stat. I spoke with my installers and I told them I think this stat might do the job of cutting out the short cycling. He recommeneded that we try...

Beenthere,

With that IAQ stat could I have my humidity level and at a rate that I know it won't reach say 15% and once it reaches my set point of 78 degrees it will cool down to 75 Degrees then...

They have it set low right now at 350 cfm if i'm correct.

I want to set the deadband setting for cooling at 3 degrees. So lets say I have the stat set at 75 degrees the ac wouldnot come on until it hits 78 degrees then kick off at 75 with a 3 degree...

Yes it is a variable speed. With the deadband i'm hoping to get my short cycling issue solved. I tried palying with the stat last night when the ac came on it would push it down then up when it went...

I have a single speed ac system and a 2 stage gas furnace. I don't believe that stat has a adjustable deadband. The only one's I have seen are the robert shaw brand and total line.

Can someone tell me the best adjustable dead band thermostat to have installed? My installer told me to do some searching and see which one I thought I would like. AS doesn't make an adjustable...

Thanks for the info beenthere. So they will be able to put a 3 ton in if needed. They feel upgrading the stat would possibly do the trick but they wanted to go back and check everything before they...

They have already lowerd the fan speed down. Could you have a 3 ton ac system with a 4 ton furnace? Is that possible?

Well the techs came out today and tried to adjust the stat. They were unable to get it to do what their tech support said it would do. I'm glad they were there when the system came on for 6 minutes...

Thanks Dingman well I did a little research and it loooks like total line is about the only stat that lets you do what I need it to do. I called a cariier company in town and they said the 1800 I...

Thanks the installers are coming out on wednesday to see what they can do about the system. They said something about programming the stat to do some over ride. I will just have to wait and see what...

I have found 2 companies that will do a load cal for me. I spoke with the general manager of a very respectible company in town. He also said that everything sounds fine due to my low humidity rate....

Thanks beenthere is that software hard to use? I'm very ignorant when it comes to duct sizing and all that stuff. I can count windows and color of shingles and stuff like that. I was going to call...

The outdoor temps are next to the humidity readings every so often. The hottest it got that day was 92 degrees. I had the house set at 76 degrees all day long the system is a 4 ton AS allegiance 14....

I would like to ask first if my unit is set for 2 cycles does that mean it will for sure cycle 2 times in 1 hour? Like 15 min 15 off 15 on 15 off? And it will kick on and off 2 time regardless. My...

That seems a little long to run without any stopping. But i'm not a pro at all. Thats why iv'e been asking all the questions on here so I know what to tell my installers.

beenthere,

My run time is 8 minutes right now and it's 82 degrees out side my off time is at 20 minutes or a little more Humidity is at 52% right now inside. I know I keep saying Thanks but I...
