Re: vent ducts

Try to match the original ducting. Other than that, any ducting material will work, including the the thin aluminum piping sold for dryer vent.

The right type of vent for a moble home

Some vents are adjustable where as you can turn them at the angle you want get those if you can,the vents dont have to be for mobile homes only. Take one of your older vents to an air conditioner parts store they should be able to match one for you.

Proper vents for a mobile home

The amount of air that flows to each room is determined by the size of the ducts. Once pressurized all rooms should already be balanced. The diffuser may alter the direction of the air but the hot air will quickly rise and the cold air return from the furnace will such the colder air from all rooms at once down the hallway. Hence the diffuser is doing it's job, It does not need to be replaced. Trailer sized diffusers are difficult to get and match. If you cut the hole size larger to allow a house diffuser you may have unbalanced the amount of heat for each room... if you cut them all larger then it is back in balance again. Weather the air goes up or sideways is just personal preference. You can get magnetic shield to divert the air if you please for far less money.

I have a Ruud air conditioner model #13AJA36A01757. The temperture out of the vents is only 70 degrees while it is running. Outside unit, low side is very cold, and the high side is not hot, not even...

If your vents are in the floor, you need to inspect your return air ductwork, you may have some air leaks pulling hot attic air in thru the vents. If the supply vents are in the floor, the return duct may run through your attic, if the duct work is uninsulated or pulled apart, it will pull hot air thru the return, causing a mixture of cold and hot air, giving you a warm air movement through the ductwork. Many service men will not catch this problem. You need to turn the unit on, go up in the attic and visibly inspect the entire return air. I hope this helps you. mark

My furnace isn't heating my house. I was wondering if this was because there is a vent from my cold air duct to the outside thus drawing to much cold air into the system. Should this vent be closed in...

If this vent is connected to the return air duct line back to your furnace I would close it off. The only reason that I can see for having a vent to the outside is if you need more combustion air supply.Thank you.

Visually inspect the duct run connections to the main trunk. It is possible that they have loosened and are losing air under the house. Also inspect the duct runs from the trunk connection to the vent connection. You want to check for any damage or other failure. It is rare to find dampers in individual runs in residential duct systems; however, it is another possibility.

I hope you find this information helpful. Good Luck in your endeavor! :-)

I have a dometic duo-therm. No air coming through ducts.

Sounds like the ducting have come apart in some areas or blocked in some way. Take the supply grills off and with a shop vacuum try and reach as far as you can.

Cold air coming from the intake of the central a/c unit. The unit is switched off and it is winter, so why would cold air come from the intake

Thanks for your question,
Just a couple of questions first, is your ducting insulated ? is there a fresh air intake on your system ? if either of these is the case, the first would be that you need to have your duct insulated, it is good practice to have them insulated as it will save you money down the road as to not have as much heat loss or cold air from the duct escaping into the home, second if you have a fresh air intake, alot of times that is where fresh outside air would be coming in from, there should be a damper on the venting, if there isn't I would suggest having one installed, normally it is installed on the return side of your ducting. Hope that was helpful, please leave some feed back as to how we did, thanks again,

Problem running heater

Its not good that you dont know where the air filter is. Odds are there may not even be one in place. In Most mobile homes they dont pay much mind to proper filtration. The heat strips are covered with dust. If the heat Strips are that bad then usually the whole unit is clogged. Is there a unit inside the mobile home?? Or is the unit outside quite large and have ducts running to it??
