Question about Intertherm P3RA-048K Air Conditioner

1 Answer

Where do the filters go on the Intertherm MGH055AB?

I moved into a modular home. It has an Intertherm
Furnace which is collecting lots of dust and spreading it throughout the house. The filters were not in it. Does anyone know what kind of filters I need to purchase and where they should be placed?
Thanks, Kathie

OK. Let me answer you, even if honestly I don't have any idea about an INTERTHERM FORCED AIR FURNACE. To get any answer, to a problem, you should describe your problem. Just telling that you don't know what's wrong with it is simply no enough information, even for a star expert in your INTERTHERM FORCED AIR FURNACE.

Keeping your whole home cool with central air.

Sometimes it is difficult to keep your home cool in the hot summer months. Also, some areas of your home may still be hot where other areas are too cool. Try this method to keep your home cool evenly throughout. Before you get started make sure your furnace filter is new. This will allow for maximum air flow.

If your living space is a single floor plan:

  1. Turn the air conditioning on
  2. Switch the furnace fan from auto to on.
  3. Measure the temperature in each room.
  4. Close the vents by about half in the cooler rooms
  5. This will force more cool air into the warmer rooms.
  6. Keep adjusting the vents until all the rooms have the same temp.

If your living space is on more than one level:

  1. Turn on the air conditioning.
  2. Switch the furnace fan from auto to on.
  3. On the lowest level of the house close half of the vents that are the closest to the stairs.
  4. This will force more cool air to the top floor where it is usually hotter.
  5. Cool air will sink from the upper floors which will keep the area near the stairs cool.
  6. Measure the temperature in all the rooms.
  7. Keep adjusting the vents until you have a nice even temperature throughout the house.
I found that leaving the furnace fan on all the time will keep your home evenly cool and comfortable. You may have to replace your furnace filter once a month due to the increased air flow. It will be well worth it in a cooler, more comfortable, and more energy efficient home.

Take Care,

My daughter recently purtchased a Trailer house which has a Intertherm Model MMHB-070ABHR-06. When we tried to service the air filter or Filters we discovered there were none. We know there should be

On some of the mobile home style furnaces, the door itself should be louvered for return air to enter the furnace. If so, look and you should see provisions for holding the filter in the door. It may be missing a long spring or other type of clip to retain it though.

If it is a gas furnace the flu pipe should come out the top, look on either side of the flu pipe for a door or pair of doors with a little sheet metal handle. If so, remove and look inside to see if there are provisions there.

Also iIf there is no louvered door, sometimes the filters just rest on top of the furnace. Not a good deal if so.

Intertherm gas furnace in mobile home..igniter comes on then nothing tries to fire byrners but nothing

by igniter I assume you mean the thermocoupler. are you turning the control button to run after you light the pilot light? Normally when those furnaces quit it is the thermocoupler that has quit. Get a new one and leave it in the furnace compartment as a spare.

How to install an intertherm furnace filter for MGHA-070AAFC-02

Hi, this is a 4 ton package unit, most filters are in the home. There should be a drop down grill somewhere in the home, maybe more then 1. If not, the filter would go on the blower back side of the evaporator coil. Remove the panel and see if it has a slot for a filter.

I have a mobile home furnace and I have no manual. I think it needs a filter but I can't tell where it is supposed to go or what kind of filter I should use. Is there a diagram available I could look at?...

The filter is usually located in the door or front cover. If you have trouble finding material you can measure opening and get one or more 1 inch thick high effiency filter. You can set these filters on their sides or upright,it really does't matter as long as you have direction of air flow going the right way. Arrows pointing into blower compartment. I have taken two or more filters and duct taped them together to get the right size. Not pretty, but it works.Hope this helps. Thanks

Where can i buy filters for a intertherm furnace in zebulon nc or raliegh nc?

I am not familiar with your area in particular but furnace filters are normally available at home and harware stores. Most air filters are 1inch thick, or close that dimension. You should measure the length and width and find one of the same size. Don't worry about high effeciency filters, all the furnace needs is a basic filter.

We have an Intertherm furnace in our manufactured home which is apparently a replacement furnace as this is not the brand showing on the original paperwork for the home. Problem is that it is very loud. ...

That is a common furnace for manufactures homes and yes they are loud....that is because there is no return duct on the unit and the fan sits jsut inside the door so the noise is not contained...
short of moving the furnace there is not much you can do about it...yes it stinks I agree with you... wish I could give you better news...
