Air Flow Issues
I have 2017 3950BR. We live in Florida and camp all year. During the summer the a/c has a difficult time keeping up. Per forum recommendations I have tried removing a/c vent covers to let a/c flow better. Helps but still not great. I have seen a lot of posts about crushed ducts. I checked that today. Nothing seems crushed. I have read numerous strings that inserting a 1 1/2 inch pvc pipe may help. Several questions:
1. Should I insert the pvc pipe into the vent or the return or both?
2. I bought some 1 1/2 inch pvc pipe but it is thick and non-flexible so how long a piece do you recommend inserting? My a/c vent only has a 3-4” diameter hole and my return in rectangular about 12x4? I only ask because my 1 1/2 pipe will not bend so I am limited on the length of pipe.
3. Do you insert the pipe at the opening or try to push in far into the vent?
4. Most stores sell schedule 40 pvc pipe. Should I be using that or something thinner.
5. If inserting pipe doesn’t work any other suggestions? Thanks in advance.
