My bathroom doesn't have an exhaust fan and just a small window. I am concerned about moisture/mold. So I don't have to constantly open and close the small window when showering, would a dehumidifier by effective enough to use in lieu of having an exhaust fan installed?

My a/c in the house is not cooling past 73 degrees during a hot day and it takes a few hours for it to even get there. I have twice called for repair and they only looked at the outside unit. Once i was told it is just too hot and the other he put a pound of refigerant in the system and said it was good. My unit is about 10 yrs old i live out in a desert community it is a 3 ton unit

We just had a new Lennox 5 ton XC16 2 stage AC (NO HEAT)

We just had a new Lennox 5 ton XC16 2 stage AC (NO HEAT) installed with matching variable speed CBX32MV air handler. Even though I live in Hawaii where it's in the low 70's at night, the system seems to run longer at the higher fan setting than I would like. Now it is cooling and dehumidifying well, the electric bills are less than old unit, it's just the cycle issue and thermostat that I question. The usual temperature settings are 77 day, 71 night. The thermostat is a 2 stage Honeywell 6000, which has been set on the 2 cycles/hour setting (3 recommended), prefer 2, not sure if it's done anything with AC or gets overided by temperature. It has a non-adjustable 1 degree tolerance. So my main questions are: 1) Which of the 4 air handler dip settings is ideal. One setting goes 50%, 80%, 100% if needed, then 50%). Other settings are 2)80%, 100%. 3) 80%, 100%,100%, 4) only 100%. Also, there is a setting where is lowers or raises air handler fan by 10%. How would that effect anything? The system is a bit oversized to me (2 story 2000 square foot, 5 ton) but if anything, you would think the high speed/2nd stage would not be on much, unless some algorithm is controlling it from the thermostat or air handler setting????? Thanks (confused home owner)

My Trane XL15i, installed in 2010, has worked perfectly

My Trane XL15i, installed in 2010, has worked perfectly until the last week. The unit cools the air, but the humidity in the house remains between 60 and 75%, depending on the thermostat setting. I keep the temp on 78 degrees typically. This would keep the humidity in the 50's. Now I have the temp set at 77 degrees but the humidity is 69%. Not comfortable. I checked the filter. It is clean. I added bleach to the drain, a monthly procedure.I checked the outside drain and no water is coming out. I don't see a backup of water anywhere. What do you suggest the issue is. Does it need a technician to repair or can I do it myself?

I want to use my cooling system to reduce humidity in the

I want to use my cooling system to reduce humidity in the house. I have a Trane ser20 system with 2 stage cooling and variable speed blower. I have the prestige IAQ thermostat with red link and the EIM interface. I understand to wire one terminal from U1 to the RH terminal. My question is when it states wire other U1 terminal to low speed fan, do I just wire to terminal G and it will call for low speed fan or do I need to locate the low speed terminal of my fan motor and wire into that? Thanks. Steve

Have A split unit Mitsubishi in a newly constructed room

Have A split unit Mitsubishi in a newly constructed room over the garage. It is hot summertime here in South Carolina with outside temperatures in the low 90s. We are not having any visitors presently so no one is using the room over the garage so we keep the temperature at about 78°.The room felt humid to me and I got a hygrometer which showed the humidity was 73%. I turned the mode on dry and left it that way for about 16 hours overnight. When I got up in the morning the temperature was 66 and the humidity was 54%. I turned the air conditioner back on cool mode and within an hour the humidity was back up to 70% although the temperature remained down for most of the morning. By noon, however I was back where I started with the temperature at 78 and the humidity at 71% in the room over the garage.I have tried reading about the "I feel" mode online but I still do not understand it. Should I be using it to maintain a comfortable atmosphere in that room? If so, how should I handle all the settings?The morning after I ran the dry mode I noted that one point that the room was quite comfortable with the temperature at 73 and the humidity at about 60%. Is there someway I couldset the unit so that it would maintain this comfortable atmosphere?

I have a LAD504TDL Frigidare dehumidifier. I cleaned the

I have a LAD504TDL Frigidare dehumidifier. I cleaned the coils and the water pan. If I run it without the cover (so that air passes around the front coil rather than through it) the front coil ices up. But with the cover in place, the ice melts and the unit doesn't seem to be collecting any water. The compressor is very hot. The back coil seems to only heat into the very first pass of the copper through the exchanger. Is this consistent with low refrigerant? The Refrigerent is R410A; 7.94oz. Can I add this myself?JA: Did you double-check the thermostat's settings? And what about the filters?Customer: yesJA: What are all the symptoms of the problem (error codes, flashing lights, etc.)?Customer: no codes, no flashing lights. everything seems to be working, but the water is not condensing. the cooling coil is only slightly cool at the very bottom and the back side heat exchanger is only slightly warm up top.JA: What happened just before this problem started? What troubleshooting have you tried?Customer: cleaned the coils, cleaned the water pan. There was dust built up on the coils. The water pan outlet was partially clogged with something like mud. But it was running OK - the fan and the compressor seemed to kick in OK. Just not condensing and outputting waterJA: Anything else you want the HVAC tech to know before I connect you?Customer: no
