Fresh air intake from outside into furnace


J

John

Hello group,
I wanted to ask this over at the HVAC group but hopefully you guys from
there will answer or give opinion here...

We are building a house here in Austin TX, we have the Carrier Infinity AC
and furnace...The builders ac guys have just about finished installing the
system except the condensor...The system has three intakes throughout the
house so we have a large Honeywell media filter..Connected on the intake
side of the plenum is about a six inch duct with a damper which is supposed
to house an AprilAire vent system. At the other end this pipe exits the
house under a gable, has a hood over it with a screen...There is no filter
installed....One other builder we were going to use was going to install the
same system and he told me the fresh air intake would have a MERV7 filter,
but these guys are installing only screen which is much larger than window
screen..I keep invisioning mosquitos, flies and god knows what else getting
sucked into the plenum from outside..Should it be normal to install
something there or would the media filter be expected to pick up the goodies
sucked in?

Thanks a million!
John

Im no pro but if you put in a media you will have to clean it. Is your
unit in the attic is the gable up high . What does April Air say.

In case you were not told, the Infinity has a New
thermostat-humidistat you can adjust fan speed at the thermostat,

I have a note into Aprilaire too..Another builder told me they put in some
sort of a prefilter that needs to be changed or cleaned twice a year. Same
as the whole house media filter (well they say 6-12 months, and I guess the
pressure sensor in the furnace will tell me when with the infinity control)
Yep..I know about the infinity control..What brougtht that up is I had
noticed they had underwired the thermostat..The Thermidistat requires a
minimum of eight wires and they put in a standard five wire stat cable..Some
nice folks turned me on to the Infinity control, and I have been researching
it and find it very cool..I mentioned it to the company who is installing
the system, they had never heard of it but are checking into it..(scary) and
will let me know..Hell I did the installer quiz on the Carrier website and
passed..I could probably install the darn thing easier then they can..I did
locate a dealer in Canada who whould sell me the control if they can't...The
Furnace is in the attic mounted in the highest part over the kitchen with
easy access from the garage drop down stairs..Easy walk up for maintaining..

Thanks!
John
