Achla Designs Room-to-Room Minuteman Doorway Fan
Customer Review
We've just received two of these, and they are everything they say and more. They are quiet enough for bedrooms, as they literally make no noise whatsoever. And they move a surprising amount of air, despite not being able to "feel" it blowing very much. We have a small wood stove positioned in the center of an old fireplace. We hung these fans in the corners of the fireplace and were shocked at how much hot (not warm, hot!) air they move (we've got one pointing in and one pointing out for optimal air flow). This product is highly recommended. The only thing unknown is shelf life...if there is a problem with the motor casing in the future, we will change our review. But for now, two thumbs up. |
Thru-Wall Room to Room Fan
Customer Review
I have lived in the home I am in for over 14 years and have always had a problem in the winter with getting heat from the wood stove into the back bedroom. With this through the wall fan it has increased the temperature by about 5 to 7 degrees. It was worth the price for the extra comfort. |
Nordic Pure 16x25x5 Honeywell Replacement AC Furnace Air Filters MERV 12, Box of 2
Customer Review
I pulled my MERV 8 out and stuck this one in... I'm surprised at the airflow difference, I thought the air flow would have gone down, but the flow is actually better. I have an incense stick burning, down the hall from the intake; it usually blows the stink'um throughout the house in a diluted manner... I couldn't smell the incense until the A/C shut off. Maybe my house will smell better now? Kind of confusing but if it takes the pollen down a notch I'll be happier. |
FC100A1037 Honeywell 20x25x5 MERV 10 Filter Media
Customer Review
The filter arrived quickly and in perfect condition. It was as described. It works perfectly and is as described. I'm very happy with service and product! |
20x25x5 MERV 11 Air Bear High Efficiency Replacement Filter (2 Pack)
Customer Review
The efficiency of these filters is comparable to none. I usually get the MERV11 filters; the more the MERV rating the finer dust particles are captured. With the MERV 11 filters I have seen a decline in the number of times my four year old daughter catches cold and allergies. These filters do an outstanding job of keeping dust out.
The seller ships very quickly usually the next day if the order is placed by 5PM the previous day. |
16x25x4-MERV12 A/C Furnace Air Filters by Nordic Pure (Box of 6)
Customer Review
I have been pleasantly surprised by this filter. Using them since 2008, they have captured quite a bit of dust and been very sufficient. Great product for the price! |
Honeywell Humidifier Installation Kit for HE360
Customer Review
It really makes the house feel warmer at lower temperatures. The installation is not that easy, but a Dremel with a cutting wheel helped a lot cutting the sheet metal. Make sure you have a floor drain as it does leak water out of the drain. |

Here a lot of variables to consider if any given humidifier is good for any particular house or not. Learn how to increase its efficiency on this page.
Bathroom drainage through cold air return.
No, you cannot do it if it is PVC unless you isolate it from the airflow. However, maybe you can do it in cast iron, check out your local code.
Calculating if your furnace can handle another vent can add a vent.
It won't be a problem, no calculations, just add one. Learn how to do it on this page.

No, it won't work this way.

Look, there are two DVD-s on the market, one of them is 80 minutes long another one even shorter. Both of them have mistakes even in the very short presentation versions!

Go to this page, and to this one, read through description of all chapters and figure out for yourself how long this kind of video should be.
Do you leave the fan on for a central humidifier?

How can I quiet the hot air ducts coming from my furnace?
This one isn’t a simple question, but you can learn how to do it on this page.
How do I know if my ductwork is properly sized if cold air return is oversized will it hurt heating efficiency?
If your cold air return is oversized it won't hurt efficiency.

Well, it is why I'm recommending buying my paid page where you can calculate offsets the simplest way possible! - No center line, no bullshit!
How do you know were the best place to put heating vents?
Just from my experience and of course you have to use a blue print.
How hard is it to extend heating vent?
Well, it is very simple. Just browse around and find info on my site.
How to properly seal air vent through brick?
You can use a mortar or furnace cement.
How to repair drum style furnace humidifier?
If it is old and dirty, do not repair - replace it! Buy one on the right or on the left.
How to stop condensation on cold air intake pipe to furnace?
Insulate it.
How to stop my furnace from going on all night long?
If your house is very tight and very well insulated and your furnace is sized for it then according to the latest home science it is fine. Otherwise, your house is leaking, purely insulated or your furnace is undersized.
How to tell if your furnace is too small for your house?
If it runs constantly and never reach the set temperature then it might be too small.
How to use water from condensing furnace?
This is a nice question! As I know this water contains some acids. Therefore, you can use it to pickle your cucumbers. However, let your mother-in-low try it first! But, no, wait a second, call your shrink first!
I assume that it is best to run each room with its own supply from the supply plenum.
But if you are limited on supply plenum space, what are the rules or does and don'ts about combining 2 rooms with one main large (combined CFM for the 2 rooms) supply from the supply plenum to each room via a wye splitter?
Example: could I have a supply of 7 inch that split to a 5 for a closet and 6 for a bath?
Yes, you can do that. its a common method in many areas.
I currently have a metal furnace filter and have used it for the last 5 yrs. should I stick with it or switch to a Filtrete High Performance Filter?
Filters except 3m are rated in MERV (Google that for more info). The higher the MERV the more air is restricted and the harder it is for your furnace fan to move it. This can result in an overheated and damaged furnace or frozen and damaged AC. The only way to know for sure is to try it and check the temp. rise thru the furnace after it has run for 5 minutes. Stick a thermometer in the supply duct downstream a foot away from the plenum and subtract the house temp from it and check the temp rise specs on the model # sticker inside the furnace. I recommend a MERV 8 filter and unless you have a newer furnace with an ECM motor and large ductwork, you can have problems with the more restrictive types. AC needs checking by a Pro to see if it has enough airflow.
I want to finish my basement and put in a new heating system but my current ductwork is not insulated what should I do?
Insulate it!
If the vent is blocked, will the furnace shut off?
If this is a modern furnace then yes. Otherwise you may die!
If you close off a hvac supply register in a room, does the air go to other open registers?
Yes, it does, but to a certain point.
Installer did not install outside air intake for 95% furnace.
Some manufactures allow doing that, but it is not right.
Is duct installation for supply and return registers inside the walls correct?
I can't see it from here. Take some pictures and send them to me from this page.
Is it against code to put supply duct through return duct?
No.
Is it normal for ticking sound coming from the vent at home?
Of course not! Get info on how to fix it on this page.
Is it normal steam coming from furnace exhaust?
Yes.
Is it ok to increase the ducting on a fan from 3" to 4" along the run?
Yes.
Is it safe to run heat through floor joists?
No, supply air always should be run in the metal, ductboard, flex or other type of duct.
Is smooth dryer venting better than kinked?
Absolutely.
Is there negative pressure in modern heat exchangers?
Yes.
Is wood touching ductwork dangerous?
No. However, according to code, there should be 1" clearance.
Just bought a brand new Goodman furnace and it is soooo loud.
Well, looks like it's oversized for your ductwork. |
Low humidity baby room.
It always surprises me when people like this one came to my site, spent 0 seconds on it and just bolted away!?! What is the rush? Are you in some kind of contest?
I Google the above keywords, it shows 109000 results, my website was third on the list.
A question: Did this visitor checked out all the 109000 links or he/she still keep working on it?
P.S. If you are not part of that contest check out this link, you may find a solution there.
Moving the furnace air conditioner copper pipe the air conditioner frozen pipe is in the way of me installing a humidifier how do I move it? You can put a humidifier on the supply or on the return. And, by the way, you should not have any frozen pipes on your AC.
My furnace sounds like it is about to take off!
Well, maybe it will! I heard that they shut the shuttle program, maybe they can use your furnace instead of.
My furnace works when I take off the clean out access, furnace goes off when I put the burner cover on.
I think that your exhaust or/and intake is plugged.
My house heat is not balanced; can I cut a hole through a wall to send heat to another area?
I do not think this is a brightest idea. However, there is a special fan on the market designed just for that, expensive too... Buy a room-to-room ventilator on this page on the right, but try to balance your system first.
Need to put damper in square ductwork.
You can find step-by-step instructions in Chapter #41 of my Ductwork Installation Guide e-book.
New furnace cost.
There is an http://www.hvac-cost.com where you can find the cost for your new furnace installation in your area, but do not forget to come back to this page and buy a furnace there.
Should I open heat registers in unfinished basement?
You can do it in order to keep your basement warm.
Should indoor fan shut down when Heat Pump on defrost?
It should be running. Most heat pumps have aux heaters that come on to temper the air so that you don't get the cool/cold air blowing out while in defrost.
The defrosting effect comes from the heat being gathered into the indoor coil as the system runs in defrost.
So, the fan must run in order to gather sufficient heat from the indoors, to melt the frost or ice outdoors.
Should there be air coming out of seams of furnace?
No.

During winter.
What to do about cold floors above a basement?
You can open supply registers in a basement or install a couple.
What to do with ugly furnace ducts in garage?
Just box it in.
What will help stop expansion and contraction in copper pipes in a heating system?
Nothing, but you can eliminate the ticking noise they make. Learn how to do that on this page.
Why is it code to put a heater vent under a window?
Well, it is not a code, but it is the best place to put it on in almost any room of a house.

If your question is about the cold air return, then yes; if it about fresh air intake, then no.
Will increasing my dryer duct size from 4" to 6" help airflow?

Honeywell RTH6350 5-2 Programmable Thermostat
Customer Review
Finally after much research finally found a thermostat that works and at a great price. Love that you only have to hit the thermostat and a light comes on. This also shows the inside temperature as well as the set temperature. You can early program the thermostat. Easy to select on and off. It is at a great price for what it offers and really you don't need the others at higher prices this one is awesome. Fairly easy to install and fit perfect over the existing hole for me. After 2 months the bills have already been reduced its hard to believe what a correct and accurate thermostat would do for ya and save me money too! Love it! |

Honeywell CF100A1009 4-Inch High Efficiency Air Cleaner Filter
Customer Review
The filter is used for my whole house. However, I have 2 other normal 20x20x1 in filters that pre filter air before it hits this one. I expect it to last a year. It is very flimsy but much lower cost that Lowes unit that appears to be higher filter quality. It would be good to review my choice next year. Need to be careful and not pick a filter that blocks the airflow too much. Also check your unit measurements as all filters are not quite 4 in thick sometimes. |
Honeywell CF200A1620/E 4-Inch Ultra Efficiency Air Cleaner Filter 16 x 20 x 4 Inches
Customer Review
The Honeywell 16x25x4 Ultra air filter replaced an Electrostatic Air filter that wasn't living up to all the hype that came with it. Before installing the Honeywell unit I had my ducts professionally cleaned, I could not believe the amount of junk that came out of my system. So far the new Honeywell Ultra is doing a fine job; there is a noticeable difference in the air we breathe and no dust anywhere. I will inspect the filter on a monthly basis and replace as needed. So far, so good. |

Tjernlund AireShare Room-To-Room Ventilator
Customer Review
Just installed this fan and am very happy with it. Quiet, moves plenty of air and relatively easy to install. One comment is the instructions don't emphasize that both the fan and the diffuser are directional that is, they each have an opening which must face the other. If this is not noticed, either unit's housing would block the air flow towards the other unit Another thing to note is the possibility of a 'block' in the wall cavity. If one unit is mounted high and the other low, one needs to probe the cavity to make sure there is not a 2x4 block midway. The hard part of this installation is accessing and wiring power to the fan, which can involve cutting access holes in the wall and possibly installing a junction box. Not for the casual do it yourself person.
In short, a professional product and far better than the usual cheap, noisy bathroom fan.
