Will the smaller opening put a strain on my air conditioning system ?

I have been using these filters for some time now and never any issues, these filters seem to do a very good job at catching fine dust and dog dander. I do change mine more often than the manufacturer recommendation, I do so every 2-3 weeks just to make sure that my system is not working harder to keep up.

I found this 1000 MPR rating to be a good compromise with my system. The higher rated version of this brand did indeed provide too much resistance and cut my air flow down way too much. Yes I would love to filter out every micro of airborne crud but I had to find a compromise between filter ability and air flow. This worked well for me. Hopefully it will for you too!

Your furnace/air conditioner should have the size needed for the filter listed on the unit. If not, the size should be on the filter that is already in the unit. Whatever the size, it will be appropriate for the unit. You should not use a bigger or smaller size than the one necessary for the unit. Hope this helps.

I expect they would fit since it is 1 inch smaller. But, I don't know if that is something you should do. I recommend calling a few different HVAC places to get their opinions.

I have the longer size item but the width was accurate for the floor opening, specifically 4 inches with the flange close to six. But beware the "Non metallic damper controls airflow" feature. In the open position this plastic device blocked more than fifty percent of the airflow available from the vent. It was so objectionable in my situation that I went to the trouble of cutting and breaking it away. Even the diecut of the surface plate blocks about 20 to 30 percent of the flow. If I now need to block the flow, my only choice is to lift the grate from the floor and wrap a piece of tinfoil around the bottom opening. If you need true variable flow, beware of this design.

That should be good. We have 3 inches at the top, for airflow. Nothing on the sides, and we have had no problems. Hope this works for you.

yes, just about right, get ready to deal with circulating the heat out. Negative fan pressure will probably be the way to go, for that area it may take 2 or 3 6" or 8" tube type fans blowin out from the top & pullin cooler air in from the bottom.

Use a larger screw. I used a larger screw when my fan wobbled. You should be fine.

Just my opinion... I am not an airflow expert...I don't think it would have a major impact. Ours makes a 90% before exiting and it doesn't cause any issue. depending on your setup I would be most concerned with distance between the fan and exit point...

You could for your own piece of mind, i didn't. Its solid as they come, I've had no air leaks at all. I mean it's certainly not going to hurt anything, but you shouldnt need to.

I think so. You open the hood, loosen the plastic shield and underneath is he filter entrance for the AC air. Open it up and look befor you but as it might be the wrong way around.

All of the windows used with this fan block it a little (~2-4inches). Haven't noticed any problems.

I think it will definitely make a difference but its not going to give you the cooling effectiveness of an air conditioner, etc.

If you have an R/O systems, you will need an air gap. Otherwise, I do not think it is necessary.

No. This is the outside unit for the air conditioning system. The heat doesn't need this. But you might need something else for it.

Relatively speaking, It will not. All gaps, cracks, and openings will allow for temp/pressure differences. It's up to you to decide how much is acceptable.

I am not sure what small means. A few inches of clearance is all that is needed. It is thermostat controlled, so it should not overheat the space.

If anything, I would think it would help not hurt. The exhaust outlet is so small that it wouldn't take away from any other outlets you may have. I run a cooler also, and have no issues...?

Not if you already have one. If you are replacing an existing A/C, you probably already have one. Just make sure it's the right size. If you are cutting a new hole in the wall for this A/C, you will need a sleeve.
