The alt.hvac snobs wouldn't answer my question, so I'm posting here...
I was going to install my new humidifier this weekend, but I see that the A/C evaporator is in the way. And I have no room on the return plenum. I have an upflow system and the evaporator was installed at the very top of the supply plenum.
Here's a diagram:
``````````| ducts to all of the rooms | ``````````+-----------------------------------+ ``````````| | ``````````| | ``````````| | ``````````| A/C evaporator located here | ``````````| | ``````````| | ``````````| | ``````````+-----------------------------------+ ```````````\\ | ````````````\\ | `````````````\\ section of duct | ``````````````\\ | ```````````````\\ | ````````````````+-----------------------------+ ````````````````| / ````````````````| / ````````````````| section of duct / ````````````````| / ````````````````| / ````````````````+-----------------------+ ````````````````| | ````````````````| | ````````````````| | ````````````````| furnace | ````````````````| | ````````````````| | ````````````````| | ````````````````| |
I have some questions about this...
1) Should the evaporator have been installed lower in the supply plenum? (It sure would have made it easy for me to install my humidifier.)2) I plan on having my A/C system replaced this spring, because it is very old and doesn't work well. Can I ask the installer to locate the evaporator lower in the supply plenum?
3) There is a little bit of asbestos tape on the duct where the evaporator lines enter. Will the A/C guys remove this? Will they ask for me to have it removed before they work?4) Depending on the answer to #2...Can I have someone evacuate the A/C system so that I can remove the evaporator and install my humidifier? There's at least two feet of duct below this (and above the furnace) where the evaporator would fit.
