Question about Heating & Cooling

1 Answer

We installed a honeywell DH90 whole house dehumidifer #B08167014 4026552. Unit is removing water but the supply side is warm air. We are wondering if this is normal or if this air should be cold.

    I have the same problem. While the DH90 does a great job at removing the humidity, it is increasing the interior temperature by 5+ degrees.

I assume you mean the exhaust side of the dehumidifier, which goes into the supply duct of the furnace.

All dehumidifiers, whether small portable types, or whole house types, exhaust warm air (which is also dry air) as they remove humidity. The whole house unit which you have is a great solution to humidity control. Since the furnace fan should be running on a call for dehumidification, the mixing of the air in the building which is circulating and the exhaust (Dry) air from the dehumidifier negates, or dissipitates the heat in the air coming from the dehumidifier.

Unable to locate the drainage for condensed water. I could look inside and see that water is accumulating at the bottom. Feddlers AEJ12E7AG, window unit. Thank you


Hello, most window units evaporate the condensate by having the fan blad sling the water on the condenser. Because the condenser is warm/hot it will evaporate. You shou.d be hearing a sloshing sound after the unit has benn running for a while, this indicates that the fan blade is picking up the water from the bottum of the ac.

I have a customer who would like a Bosch AE-9.5 tankless water heater installed in the master bathroom. The master bath is located at the far end of the house & they are wasting a great deal of water...


In theory it sounds good, but I don't think it would function properly. Most folks install a low boy 20 or 25 gallon water heater near the master bath and use the home's cold water feed as the supply line. That way, the water for the master bath alone, will always remain hot.Of course this would involve some plumbing modifications.

Of course, the other less expensive solution, would be to insulate the hot water pipe(s) feeding the master bath, from the existing water heater. That way, there would be no heat loss in the pipe(s) so the water in the pipe would remain warm to hot all the time.

Either of the above solutions should heat things up for your customer.

Amana Prestige Central A/C,inside fan on out side fan not running,breaker in house good out side switch on,is there a breaker in the out side box ? it is not seen.Out side fan feels reel warm but not...


Hi!!

Replace motor fan and capacitor of the outside unit. it is a very simple task. Turn breaker OFF. Then all you have to do is remove about four screws from the top grill, about four more that fasten the motor fan assembly, unplugg electrical connectors and label them and install the new one and switch fan blades.

No special knowledge is required to perform this job. Cost: about $140 +-.

On the other hand, you call a HVAC technician, they supply the motor and capacitor, otherwise they won't give you warranty. Cost $300. Look on the Yellow Pages for one in your neighborhood.

Good Luck!! Rate this post!!

What is cooling and dehumidification mode


When dehumidification operation is set by remote controller,the intake air temp.is detected and the setting temp.is automatically set according to intake air temp. expl. Intake temp.78.8 set point will be 77. When intake air temp.is 2deg.below the setting temp.the indoor fan operates at iow speed or stops.It is just a way to controlle humitity rater than just temp.Some systems reach setpoint before enough humitity is removed,making house feel stuffy,or damp.

I have a new two stage 5 ton heil installed in my


A 5 ton unit on a 2300sf house seems too big.
The only way to tell for sure is to have a professional come out and do a heat load calculation. I understand this is an old house with limited insulation, but many other factors are involved in determine the unit capacity needed including windows, overhangs, infiltration, trees/bushes, house position, etc.

An oversize A/C unit will cause the exact problem you are having. It cools so fast that it doesn't have time to remove the humidity. Please check this and if this is the problem then a band-aid solution is to add the dehumidifier. The correct solution is to install the correct A/C unit (I know, too much $$).

Also, you need to make sure the condenser unit (outdoor) and the evaporator unit (indoor) are correctly matched. Ask your A/C tech to check.

Also, check that the fan is operating at the correct airflow. Too much airflow and you'll have high humidity in the house. Again, ask your A/C tech.

Finally, check that the ductwork is properly sized. Too small or too large will cause you problems.

If nothing comes up, also check for infiltration. This is outside air getting into the house. Check all the obvious places such as around doors, windows, cracks in the wall/ceilings, etc. But also check that air is not getting sucked into the return air duct due to leaks or improper installation. This is all too common. Everything needs to be sealed and tight on the return air path. Remember, this duct is "sucking" air and any leak will **** in hot, humidity air into your A/C unit and then into your house.

I hope this leads you to the problem. Good Luck!

Central A/C takes a long time to cool house


The system should be either R-22 or R-410A
You need to go outside and feel the suction line (the big line) with the unit running, after the house is cooled down, it should be cold and sweating,if the humidity is not to low, if it is your unit is probably ok. High Effeciency units
usually have a higher suction pressure and temperature and can run longer, if it's sized right. After the house is pulled down to temperature and starts cycling, it should come on and go off about 3 times per hour. The longer the unit runs the more dehumidification it should do.
