First, I've been blasted in other groups in the past for posting
questions that belong elsewhere. If I'm guilty of this, please point me
in the right direction.
Second, my wife and I are selling our townhome and the buyer's realtor
sent an inspector (without setting up an appointment--still angry about
that one) who gave us a list. We're not unwilling to use an HVAC guy
to do the repairs, but I want to make sure that's necessary or if
that's the right person to call for the following:
1. Clean dryer vent on roof (clogged w/ lent)
2. P Trap removed from attic heat pump air handler--can this really
result in condensation drain problems during the AC cycle (we had to
remove it because it was clogged and causing a backflow of condensation
and replaced it w/ a piece of straight PVC pipe.
3. Air Flow to downstairs heating/cooling ducts is weak: What can we
really do about that? Is it a duct cleaning issue?
The lint filter can be cleaned by anyone willing to go do it. A HVAC tech
is rather expensive for that type of work.
The P trap prevents stuff from coming back up into the pan. Things like
bug. Put it pack in and if it clogs, that is hte problem of the new owner.
Yes, things like that must be maintained and cleaned every year.
The lack of air flow is dependent on many things. Proper size blower,
ducts, distribution system, etc. Not being able to see it, I can't say for
sure. Sometimes it is just a matter of closing down vents in other rooms to
force more air to the ones lacking. If it is heating and cooling properly,
the air may be sufficient. If not, you may need some help with that. Oh,
be sure the filters are clean and not causing any restriction.
There is a nice trap for condensate lines that has access ports. There
is also a neat brush to clean the gunk out of the trap. The trap is
transparent, so you can see if it is clogged. Get one of those. It
cements in place. Any HVAC supply house. Get the right diameter. Easy
In so far as it possibly being a "duct cleaning issue", while anything
is possible, any duct cleaning is more than likely needed on the return
lines, not the supply lines, which isn't likely to be causing that type
