Yes you can. Orders can be made via our web site shopping cart or by contacting us directly @ 518-798-5500, 1-800-654-8263.  

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 itís 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 ĎVenmarí 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. Whatís 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 itís 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 canít I just open a window or door for some fresh air?

Although some people think that could work, at todayís 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?

Itís 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 canít 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?

Hereís 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 donít 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.
