Q.
What is your opinion of Venmar Ventilation
products?
Venmar products are some the finest in the
industry. They have the latest technology, the
best support and excellent warranty. We
believe that because of this, Venmar is a great
investment for any home experiencing ventilation
related problems.
Q.
My neighbor has a vanEE
made by Venmar Ventilation and says it’s the
best. You are selling Venmar made by the same
company. What is the difference?
Years ago Venmar Ventilation began selling heat
recovery ventilators in
Canada
under the vanEE name.
Some came into the states, but a few years ago all
units coming into the
U.S.
were branded with the ‘Venmar’ name. There are
still many vanEE units
alive and well here. I have heard many stories of
owners not leaving them behind when they sold
their home!
Q.
I want to install a recovery ventilator in my
existing home. Can this be done and will it work
efficiently?
We sell to customers frequently that are doing a
retrofit installation. You will still have and
enjoy all the benefits of the heat, energy or HEPA
ventilator and it will work efficiently as long as
you follow the manufacturers recommended
installation procedures.
Q.
Is a heat recovery, energy recovery or HEPA unit
fairly easy to install?
We get this question all the time. If you are
little bit on the handy side, follow the
installation guidelines and think through your
plan then you will have no problem getting your
new unit installed. And when you get all done pat
your self on the back for a job well done! (Try
not to brag too much to your neighbor.)
Q.
Do I need to install additional ducting?
The basic retrofit installation does not require
additional duct work, only the small amount of
ducting for hooking the unit up. For a new home
you will be ducting the exhausting humid, stale
air from your high humidity areas such as the
bathrooms and kitchen. You will duct the incoming
fresh, dry air into your living spaces such as the
living room, bedrooms and dining room.
Q.
How easy are they to maintain?
Simple, follow the
suggested filter maintenance schedule in the user
manual. Some main controls have a reminder
light indicating its time to check the filters.
Your vinyl condensate drain (HRV models) should be
clean and not kinked. Be sure to inspect the
outdoor hood(s) for any obstructions such as
leaves or snow.
Q.
What’s the difference between a HRV
(heat
recovery ventilator) and an ERV
(energy
recovery ventilator)?
A HRV brings in the fresh air and exhaust the
stale air while at the same time recovering the
heat from it. An ERV does that too, but has the
added benefit of capturing the humidity from the
incoming humid air during the warm months which
helps you keep from adding to the air conditioning
load. In the colder months the ERV also captures
the humidity from the exhausting air and puts it
back into the structure.
Q.
There is a lot of hardwood flooring in my home.
Which model would you suggest?
Since you want your home too maintain some
degree of humidity during the bone dry colder
months, we would suggest using an ERV model. If
you have an HRV model it’s suggested that you
limit the run times too allow for more humidity to
be retained by the structure.
Q.
Do you stock all of the Venmar models?
We normally have several in stock. If we do not
have the model you want we will arrange for direct
shipping from Venmar to you.
Q.
What should I do if I need a part or a filter?
Since we keep a supply of both in stock you may
order what you need through our indoorairquality.net
website shopping cart. Should you have questions
regarding your order feel free to contact us
directly, send an email or a fax.
Q.
Why can’t I just open a window or door for some
fresh air?
Although some people think that could work, at
today’s heating prices you would have to pay
some very high bills. The amount of fresh air you
get would be minimal compared to having a recovery
ventilator that takes out the stale, humid air and
replaces it continually with the fresh, dry air.
Q.
I have window condensation that mostly disappears
during the daytime, but comes back again during
the night hours. What is causing that?
It’s not as mysterious as it seems. The built
up condensation level in your home shows up during
the colder, sunless nighttime hours on your frigid
windows. As things begin to warm up during the
daytime the amount of condensation dissipates and
on some windows melts. This occurs over and over
causing the damage you can’t stop. By installing
a heat or energy recovery ventilator you will
bring in the fresh, dry air and send out the
humid, stale air continually. In a short amount of
time you will have control over the humidity in
your home.
Q.
How often will my HRV/ERV run?
During the first couple days your HRV/ERV will
want to run continuously on high speed air
exchange since it is detecting a too high level of
humidity. Once it brings the humidity lower and in
line you can adjust the main control setting
according to the outdoor temperature.
Q.
Our recently built house has good windows and was
constructed very tight. Why are the new windows
showing condensation?
Here’s what is happening. The humidity level
is so high that the condensation is forming on the
colder surface of the windows. New houses still
need ventilation too since they are constructed so
tight (for energy savings) that the humidity from
the new construction materials and the lack of any
fresh, dryer air provisions causes the building
envelope to retain a much higher level of the
humidity. Just daily living itself (showers,
cooking, and breathing) creates a tremendous
amount of the humidity.
Q.
Do I really need to balance my unit?
For the heat or heat recovery unit to operate
at its peak efficiency and properly, yes balancing
is vital. You want to have a nearly equal balance
of the two air flows.
Q.
Where is the best place of the main control?
The main control should be mounted near your
present thermostat where it is handy to get to.
That place should be away from any humidity
producing rooms such as bathrooms or laundry and
out of direct sunlight.
Q.
We will be adding another room. Will my present
HRV/ERV be able to handle that also?
That will depend on the area size of the new
room and whether or not the unit had sufficiently
performed previously. If it did and you are adding
a small amount of cuft
you should be fine.
If you are adding a large area it would be best to
consider the next size up model to replace your
existing unit with.
Q.
What is difference between the Venta,
Supra and Ultima
controls?
-
The Venta is a
basic control has off, low/high exchange speed
-
The Supra has off, intermittent, low/high
exchange speed
-
The Ultima
has off, intermittent, low/high exchange speed,
filtration
All three are used with the Solo, Duo and HE
models. The Constructo
model has its own control which is called Constructo
with off, low/high exchange speed.
Q.
I want to change the main control to the Ultima.
Is that able to be done?
If you have the newer
AVS
Solo or
AVS
Duo models it can be changed. Some customers wish
to make this change so they can have the
filtration mode to make good use of the third
filter bay for the optional pleated, charcoal or
electronic filters.
Q.
Can I add the optional filtering to my recovery
unit?
If you have one of the
AVS
Solo or
AVS
Duo models then you have a third filter bay that
is used for the optional pleated, charcoal or
electronic filters. You will leave the two
standard foam filters in place.
Q.
Will heat recovery, energy recover or HEPA
ventilation help my asthma?
Having a continuous fresh air environment
in which to live can be of help with asthma. What
helps more is adding the optional pleated filter
in a
AVS
Solo or
AVS
Duo. Even better is having the new HEPA 3100 HRV
or HEPA 4100 ERV. The HEPA filtration captures up
to 99.97% of 0.3 micron and larger size particles.
Q.
I get unexplainable headaches. Will a ventilator
help?
We have been told by customers that the
addition of having continuous ventilation did help
remove their headaches. Now we don’t know for
sure what the causes were, but we do know that our
homes are full of various pollutants that we
breathe in day and night..
Q.
I installed a HRV. Now I smell smoke from my
fireplace/woodstove. I never did previously. What
should I do?
There have been customers contacting us
with a problem like this. What we found were these
situations. One was that the recover ventilator
was never balance or balanced improperly. The
balance is very important to having near equal air
stream in an out of the home. There is an
exception though for those homes with a
fireplace/woodstove. The incoming air balance
should be slightly higher than the out going air
side to provide a slightly higher indoor pressure.
Every home has different construction and that
makes the balance all the more critical.
