    My system is oversized. At this point nothing I can do about it, unfortunately, but I still do not 100% know what CPH does as per my original post. Or what this other option is in my thermostat...

    I should have added that I have a 1F97-1277 thermostat. This is the manual:

    I am not seeing anything...
  3. Can someone explain what exactly cycles per hour does?

    From what I have gathered, this setting will force the AC to turn on for a set period of time, wait a set period, etc so that it runs the set amount of times.

    For example, 2 CPH would run for 15,...

    Thanks for the info. The unit is definitely dehumidifying as I hear the condensation line dripping in my gutters (it comes out of the attic over my head) all night. The main 2nd floor return is also...

    Nothing more than sometimes my upstairs can get to 58-60% RH at 70 degrees temp. To me thats a little high.

    Any advice on what would need to be done on the upstairs unit to get it to dehumidify better? Lower fan speeds? I am already set to medium and am concerned it would ice up the coils if I go to low?...

    Do I measure the supply temp at the air handler or the actual supply?
  8. Forgot to mention, when I put my hygrometer...

    Forgot to mention, when I put my hygrometer directly on top of the supply, the RH went through the roof. Over 70%. I ready that this is normal because the air is so cold, but wanted to confirm if...

    I am in Long Island NY, which can get quite humid during the summer.

    The second floor return is located in the ceiling.

    Any tricks on how to determine if its return leakage?
  11. Relative humidity increases the lower i set AC and the longer I run the system

    I am battling semi-high humidity in my house (especially upstairs) and am trying to fix it before I go down the dedicated dehumidifier route (april/ultra aire). On a hot humid day my house can have...
  12. Proper return and supply temperature differences?

    Having some humidity issues in my house and performing some diagnostics from the valuable posts here on the forum. I have two brand new ac units with one air handler in the basement crawlspace and...
  13. Would increasing length of hot air return duct affect performance?

    We have a new AC that was installed in our attic where they put the hot air return duct straight through the middle of the attic. We are going to be plywooding the attic and possibly finishing the...

    Sound good. Thanks for all the advice. They will be coming today and I will show em everything that should be resolved.

    I assume for the return box they should mastic and tape each edge of the...

    Thanks precision hvac. I am almost 100% sure the return box they added is not insulated on the inside. I saw it right before they installed it and there was no insulation at all on the inside.

    As...

    Can anyone tell me if there should be insulation around the return box?

    They are coming tomorrow to take a look at things and do not want to be a pain in the ass asking for things that are not...
  17. Air quality issues after some recent attic HVAC work. Pics of work enclosed.

    I recently had some HVAC work done in my attic to help alleviate higher temperatures in my second floor home office. As part of this process they installed a hot air return in my office, moved the...

    Guess we are unusual as we like it cold :) 75 is way too high for me. I am not comfortable in my house with the temps that high.



    I don't know what this means. What do you mean by a setback?

    Sorry, I missed Ryan's question. During the week as I work from home, I typically keep the therm at 69. Really hot days the AC will run all day.

    Noone is doing it. One company actually said he doesn't believe in it. I honestly don't get it and it leaves me with little options unfortunately. If I found someone I would happily pay for it to...

    I have seen the ducts in the attic and I am pretty sure they are at least 8". Definitely do not look 6". They are flex duct runs. The insulation is blown in with about 12-16" of insulation. I may...

    I also forgot to mention that Company A stated that as part of the cost they would need to rerun the refrigerant line as it is incompatible with R-410A. Company B stated that they can use some sort...

    Hi All,

    Last summer my upstairs zone air conditioner started to not cool. When a company came in to see what was wrong it was determined that there was a lack of freon. I a month or two later it...
