Check to make sure all wires are connected, it is possible that removing the cover caused a wire to come loose.
-
You should probably take a look inside the registers if you can, and check the screws and connections on the outside. Could be a rattling part.
Also, next time, post a reply to this thread (reply...

57 degree output temperature is right on the spot (especially on the fourth floor with the compressor far away).
What is your set point? 75 on the fourth floor (with heat rising from other units...
-
3 years is nothing for an AC unit. My unit is almost 20 years old (I live in south Florida where it runs almost every day of the year) and does not show signs of 'overuse'. Central air units are...
-
Outside copper lines don't really need to be insulated because the condensation is not a problem, but anything inside should be just in case of water drip. It can be a few years before a small drip...

Temps in the low to mid 50s are what you want. For vents that are very very far away from the air handler, around 60 may be normal. Anything above that and you need to have something fixed.

80 degrees is very warm for a room, also it must be humid in there (unless you live in a super dry climate).
- turn thermostat to 75 (avg room tempearture)
- make sure filter is clean
- check...
-
It means that the filter needs to be changed/
-
Where do you live? If it is in a humid climate, leakage from windows and doors could be keeping the humidity high.
-
Air handlers can be quite loud, depending on how big they are. I suggest putting heavy sound insulation around the wall and ceiling on both sides. It's the cheapest way to get what you want.
-
55% humidity is perfectly normal, if you live in a humid climate (especially Florida). If you live, say in California, than that's a bit high.
Measure the temperature of the air coming from the...
-
First of all: Check the temperature of the air coming out of the vents. Use a thermometer to get the temp, or just stick your hand into it and it should feel very cold. The ideal temps are from 52-60.
-
It's obvious that running it constantly uses more power. A blower motor won't die in 10 years, and still, most people are more than willing to pay the extra cost of running it than go through the...
-
It all depends on how long it runs. Having it cooler in the day and cycle more often may have it run less than if you have it warm in the day, and then try to cool it down in one shot. That one shot...
-
Yeah, just replace it. DO NOT buy a white rodgers digital tstat, because I have seen many that have temp readings that are way off, by 3 degrees.
Almost all other tstats are good, just buy one...
-
Running the fan doesn't cost much at all, because it is only a fan, about the same as a large ceiling fan. The compressor outside is what uses the most energy, more than half of the whole system.
...
-
I've tried this before. For me, leaving the tstat on a cooler temperature during the day, instead of changing it, costs a little less for me (I left mine at 76, in an apartment though). It may be...
-
Try changing the filter. A 'usual' noise from an air handler is the sound of air passing through the filter and evaporator coils, in addition to the fan running. Check the coil and make sure it's not...
-
Fans on high ceiling rooms will mix the warm air on the ceiling into the cooler air in the living space, so it is not always the best way to feel cooler.
-
Also make sure your tstat is calibrated using a few other thermometers to test it. Some tstats are off by a few degrees from the factory, especially the horizontal White Rodgers ones. Those can be...
-
I live in an apartment so I keep mine at 76. There is no 'best' setting, it is only what you think is the right balance between electricity bill and comfort. 75-79 is what most people think.
-
Test it out with another thermostat or thermometer. Put it right next to the current one, and see what it says. Easiest way to find out what's wrong. What you think may feel 'cooler' may not actually...
-
I thought of that reason, but I have felt the wall and it always feels normal, just as if the washer were off. Unless the washer could heat up across the counter, then transmit all the way through...
-
It may seem like the heat, but it is not. I put two other thermometers there, and they both read the same temp as if it were off, but not the thermostat. One was another thermostat, and one was a...
-
Whenever I run the dishwasher, the temperature on the thermostat located on the opposite wall goes higher, even though the actual house temperature doesn't. This causes it to run for a lot longer,...
-
Wow, 10 ft ceilings... that could be why. My house has 7'9" ceilings!
A return duct will put hot air out of the room better than just have it being taken out of the room through the cracks around...
-
Regarding the above post,
Does the room have lots of windows that face west? Generally, west facing is much hotter in the summer, and south is hotter in the winter.
-
- How big are the windows?
- How much wall space?
- How much sun do the house walls get?
- How high are the ceilings?
All these factors can dramatically effect the size needed.
-
Check your thermostat manual or find one online and look for something called a swing mode. This will tell the thermostat how many degrees above the set point it will turn on and off.
-
Your unit is most likely very low on freon. Have a trusted professional check it and see what he says.
-
Basically, the bigger it is, the less noise it makes. The air taken in will be the same regardless of how big you make it.
Just don't make it too small otherwise it will make a hissing noise.
-
As mentioned above, air conditioners of all type suck in room temperature air, pass it over an evaporator coil, where it gets very cold, and puts it back into the room. However, in order for the air...
-
Check temperpature of the air coming out of the vents to see if the unit is actually working right.
It should be anywhere between 54-60 degrees to be working up to standards.
-
You haven't use AC since October, and you're in Florida! Yikes! I haven't used the heat at all this year (but I am in Ft Lauderdale).
You must be very far up north.
-
I prefer vents that face out from the interior wall. This gives a very even cooling and you can direct them to any part of the room you want. But if you want it in the ceiling, put them as close to...
-
What you could do is buy sheets of insulation board or some other rigid material, cut them to the size of the register, then stick them in tightly. The amount of air coming out is controlled by the...
-
Check the batteries in it. This can be done by pulling it off the wall and looking for a small piece that pulls off, usually containing 2 AA batteries.
-
This is due to the higher velocity of air in the vents.
The best option would be to lower the blower speed. If that is not possible, use a supply vent with large fins instead of many small ones....
-
Two 1.5 ton units would do well.
-
Make sure you have a red wire that is labelled RH (for heat) or one that was connected to the slot on the old thermostat that said RH.
-
The thing is, the air conditioner cools to its max extent (it is very small for the apartment) and the vent temp ranges from 52-56 degrees, which is cool enough.
No matter how much I tell them,...
-
Anyway, since replacing isn't an option, what do you recommend I do to clean it? I have no hose connection around so I can't use that to clean it. I don't know if I am allowed to call an AC tech to...
-
Nope, that would mean they would be replacing all 280 or so condensers in our apartment complex...
They are 16 to 17 years old, have never been cleaned, and will not be replaced unless they break.
-
The coil definitely needs to be cleaned. The problem is, that will never happen because the maintenance doesn't believe in condenser coil cleaning.
The airflow coming from mine is not as strong as...
-
I was wondering if the temp coming form the outdoor condenser should be really warm, like that coming out of a furnace, or just mildly warm, like around 90. Does the temp coming out have anything to...
-
I have a RiteTemp one and I use a G, Y, W, and RC (I live in Florida - we use this thing called air conditioning in the winter). Programmable.
-
There should be labels on the old Honeywell one where each wire is sticking in. What is a common wire?
Post a picture and this would help greatly to solve your problem.
-
I just got that tstat a week ago, but I live in Florida and only had to install it on a A/C unit with the indoor part of a heat pump. My only wires were W, Y, G, and RC.
-
I've never heard of other people having Evcon... I have a 17 year old evcon (now coleman) and it is called a Red T Coil.
What are some model specs on yours?
