Is the efficiency of an AC decreased by dry air?
Would that (dry air) impact the efficiency of the AC unit? In what sense (will it improve it or it is the opposite?

So if you have both an AC and the DH you should run them both to speed up the cooling?

Yes, running both is counterproductive.

The dehumidifier dumps the heat it uses plus the heat of vapourization into your house then the AC has to acquire both then move them out. The AC dumps the heat if its own use and the heat of vapourization directly outside, one less step.

Might try and leave the fan setting on your thermostat to on instead of auto overnight and the temperature and humidity of the basement and main floor should balance out. That is unless you played around with the dampers and covered up return air grilles.

I have a Trane XR15-018 for AC.bubuski wrote: ↑I recall you bought new Trane units last year. Ask your contractor if they can return to enable the comfort-r mode. With comfort-r, it keeps the blower fan at 80% for the 7.5mins at startup. This concentrates on enhanced dehumidifying before cooling.
Additionally they can break the BK jumper and attach a humidistat. This will set the blower at 80% till the humidity level is achieved.

This is the proper solution. I have a Lennox heat pump, and in dehumidification mode it runs the fan at lower speed. This increases contact time with the air and improves extraction of humidity. A proper thermostat will allow you to control target humidity and degree of overcooling that is acceptable.CuriousC wrote: ↑thanks, I will have a look at this when I have some time.
This looks like something that the owner can do himself. It might affect the warranty though ..I might chose to run the idea through the vendor first.
although it does not sound fair that all the adjustments have to be done by the vendor in order not to lose the 10Y warranty (parts and labor) that I have.
I have not been told anything in this respect but I will play safe and ask them
