i was going to suggest your condensation drainage line from a/c might be clogged. you ever notice houses have that white pipe that come off, thats where the water drains from the a/c after it naturally dehumidifies the house---- or in her case have to empty the portable dehumidifier bucket several times a day--- your line is probably clogged. maybe

Glad I stumbled across this video. I kept wondering why in the afternoon my humidity level would keep rising. When we would put the baby down for a nap, we would switch the fan to 'On' for the air conditioner and set it on 69. Usually like 2-4 hours of constant fan with the A/C cycling was the cause. Switching it to constant fan was just purely to add "white noise". I didn't do it yesterday and the humidity level never rose above 55%.

I have been fighting with my air conditioner company for 22 years. When air conditioner is on the humidity goes up to 70% and when off, it’s 45%. They just tell me that’s fine and I have 5 dehumidifiers sitting around on floors just to keep high humidity from damaging house. I have always had fan set on auto although it is constantly running because the dehumidifiers add a tremendous amount of heat when running all day.

The Filter which is MERV16 will not let a much air flow which means it will take longer to cool which means there will be more humidity removed when the A/C is operating.

I keep my fan set to auto, but the humidity level is higher than I’d like. I might try one of these 5 inch thick MERV 16 filters to see if that lowers the humidity in my house. As you mentioned, maybe it will take longer to cool, which should allow more humidity to be removed.

Something else that needs to be mentioned, is that the fan speed setting for the evaporator needs to be set at 400 CFM per ton of A/C. In this case, 1200 CFM. If the inside unit fan speed is set too high, there will be no way for the A/C unit to effectively remove the humidity in the house air. The inside evaporator in the basement will cool, but not dry the air if the airflow is too high, resulting in a cool, but very damp home.

Because of it's larger than normal surface area, the pressure drop across this 5" thick filter is lower than a typical 1" pleated filter. So it doesn't make the fan work harder & it keeps the AC unit and the air much cleaner. No motor change necessary but it is important to check the total system static pressure in order to make sure that the duct system is not too restrictive.

Putting the filter at the return vent does not guarantee that the filter will catch all the dust in the house. I am in an apartment and the only thing they put in the furnace is an electrostatic screen which doesn't do much good. I have filters in front of my intake vent but they don't pick up all the dust blowing through the system. Because that screen is the only thing in the unit, it is loose and dust is pulled in from outside. They told me that they lost the key to the furnace door so I'm thinking of picking the lock so I can put an actual filter in the thing.

In spring and summer I have higher humidity than I like in the house. Several years ago I replaced my old Trane with what the dealer recommended - a very high-efficiency unit (even thought the old unit was very efficient and gave us no humidity problems whatsoever for almost 20 years and ran like a champ. But a freak problem NOT within the Trane unit forced us to scrap it (sadly) because the coolant needed was no longer available. So we were forced to buy a whole new system in order to comply with the new regs. Ouch! The new unit cools like gangbusters but it does it so fast there is not enough time to dehumidify the house like before. Have to have napkins under your glass of ice tea or whatever to soak up the condensation. Never had to do that before. I complained several times to the dealer/installer but to no avail.
@Alexlfm
@Alexlfm 5 жыл бұрын
mweb9 I would change your thermostat. If you have a high efficiency unit you should have staging meaning two stages of cooling. I know with the ecobee thermostat (what I recommend and use) it will run on a dehumidifier mode with the lower stage not to cool but to dehumidify (obviously). Often the thermostats these manufacturers push with their units are both overpriced and bad. You shouldn’t be having those issues with any sort of newer, efficient unit unless they way oversized the system.

The AC coil is not cold when it is not running , so it wouldn't pick up humidity off the coil just running In fan mode. She's pulling in alot off outside air because off the lack off insulation. Might as well run the fan with the window open.
@Jacob-5949
@Jacob-5949 5 жыл бұрын
The AC coils get covered in frost when the AC is in on. Typically the fan shuts off when the AC is off and the frost melts and flows out via the condensate line. With the fan on all the time the warm air was evaporating the frost from the AC coil and putting the moisture back into the air instead of draining out via the condensate line.

@@Jacob-5949 The evap coil shouldn't have frost on it. If it's icing up thats another issue. When the compressor turns off , the evap coil doesn't stay cold for long . After a few min your coil shouldnt be cold anymore. If you're running the fan over a room temp coil , I don't see how it'll pick up moisture from it. Unless I'm wrong.

The evaporator coil should never have any ice for frost , that would indicate an issue . I have seen many cases here in VA of someone running the fan all the time and having high humidity levels and the houses were pretty tight. The air passing the coil, after it’s off of course, will pick up moisture that hasn’t drained off of the coil and humidify the air.

I had the same thing happen with my system when I ran the fan continuously. I disagree with Richard regarding the UV light, particular in the age of Covid. I am undergoing chemotherapy, and I have UV lights on my 2 systems in my house. While the light won't do anything against allergens, they certainly are effective against viruses, bacteria and mold spores. Plus, you can now get UV lights that don't generate ozone. These are relatively inexpensive insurance, and provide peace of mind. Obviously, they need to be maintained but so do the filters on the system.

In general, UV light can harm the genetic material in a variety of pathogens to reduce or eliminate their chance of reproduction, essentially rendering them useless. In fungus and bacteria, this damage occurs in the DNA, while the RNA is impacted in viruses. [1] In one promising study, far-UVC light, a powerful form of UV light, has already demonstrated an ability to “destroy the outer protein coating of the SARS-Coronavirus”-a different, yet related virus to SARS-CoV-2. [2] This destruction effectively results in the virus’ inactivation. And due to the similarities between all human coronaviruses, it’s thought that far-UVC light would prove to have a similar inactivation effect against other related coronaviruses, including the one behind COVID-19.

No insulation, with masonry block wall construction in Florida. So it stands to reason. The number of south and west facing windows wasn't stated. That also affects the heat load calculation as well.

Sometimes you have to get creative with return air... But never use flexible duct for your return air. Build a box and connect to that 💪

1Ton of air condition covers 600sqft. She has 3 ton = 1800 sqft of cooling. She has a 900 sqft home. It's over sized. This guy has no idea what he's talking about. Imagine telling a customer you have 90% humidity because of your fan being ON. Moronic.
