    I'm sorry but it didn't answer my question at all.

    My heat runs on oil....I just need to know how to turn the heat that is generating from the wall furnace...There is some heat blowing up at the top. The air is coming in like it should throught the floor vents, but that little bit of heat in the wall furnace is keeping it somewhat warm in the hall and bedroom where it is at...I just need to know how to cut it off. Do I take the front piece off and do something? Thanking you in advance.

You need to make an adjustment inside the thermostat on the wall.
To make the adjustment, lift off the cover from the thermostat and locate the anticipator. If your furnace is running short cycles, the anticipator is probably set on .2 or lower. Check your furnace manual and move the lever or dial to the setting they recommend which is normally in the .3 to .4 range. Your short cycles should now cease. Some thermostats have an anticipator for both a/c and heat.
either the switch is defective or there's a problem with the combustion air blower. In many manufactured home furnaces, the centrifugal switch is located inside the combustion air blower. In that case, repairing the switch would also mean replacing the blower. For the most part the blower assembly contains four parts -- the blower wheel & it's housing, the blower motor, the fan capacitor and the temperature control switches. Furnace filters should be changed every 30 days. Always use the type of filters recommended by the manufacturer. On most manufactured home furnaces, the filter(s) are located in the furnace door. The doors generally lift off and there's often a top and bottom door. Thanks. Keep updated for any more query. You can rate this solution and show your appreciation.

    I thank you for your prompt reply. I took the cover off the thermostat and moved the small lever to 4. It was on 2. Unfortunately I have no manual to this mobile home. Should I cut the switch in the laundry room that allows the heat to come up through the floor vents that goes to the wall furnace back on? Yes, there are two parts to the furnace. The heat is coming from the second level. Not blowing out hard...I can put my hand up there and feel the warm air.....That just doesn't seem normal to me....If I took the panel off the front of the furnace would there be a switch to turn that off. The cool air is working well through the floor vents, but there is just enough warm air coming from the furnace to keep the back area warm where its located. I hope I'm making some sense...All I want to do is shut down heat coming from the furnace.......Again, thanking you in advance....

Hello,

The factor you may want to consider is the airflow distribution. The unit may be working fine but if you do not have enough air directed to that part of the house it will not cool it fast enough before the rest of the house reaches the desired temp. The second thing I would look at is whether of not they sized your system correctly. If your system is too small for your house then it will continuously run and never cool your house adequately.

Check also the thermostat to ensure it regulate the temperature as well.

Take care.

How a Central Air Conditioning System Works
amn_howac.jpg


Facts:
  • The typical central air conditioning system is a split system, with an outdoor air conditioning, or "compressor bearing unit" and an indoor coil, which is usually installed on top of the furnace in the home.
  • Using electricity as its power source, the compressor pumps refrigerant through the system to gather heat and moisture from indoors and remove it from the home.
  • Heat and moisture are removed from the home when warm air from inside the home is blown over the cooled indoor coil. The heat in the air transfers to the coil, thereby "cooling" the air.
  • The heat that has transferred to the coil is then "pumped" to the exterior of the home, while the cooled air is pumped back inside, helping to maintain a comfortable indoor temperature.
  • Central air conditioning can also be provided through a package unit or a heat pump.

Benefits:
  • Indoor comfort during warm weather - Central air conditioning helps keep your home cool and reduces humidity levels.
  • Cleaner air - As your central air conditioning system draws air out of various rooms in the house through return air ducts, the air is pulled through an air filter, which removes airborne particles such as dust and lint. Sophisticated filters may remove microscopic pollutants, as well. The filtered air is then routed to air supply ductwork that carries it back to rooms.
  • Quieter operation - Because the compressor bearing unit is located outside the home, the indoor noise level from its operation is much lower than that of a free-standing air conditioning unit.

I have an old 1985-86 coleman central heat and air need manual


The filter is located before the blower if your Coleman is in a mobile home it will be in the door facing. If it is a standard ac/heat application and a regular residential furnace the blower in the cabinet on down flow (ducts in floor) will be above it and possible in the duct connecting in the top. If its the other way (ducts in ceiling) it could be right under the blower. Either of these could have a filter cabinet on the furnace or could have a filter grille at the end of the return air duct (where the air is sucked in).

Ductless minisplit in old mobile home


ductless mini split units are a very good choice!  they are obviously quieter, more efficient and easier to maintain than window units. the downside is the initial expense of buying the unit, but this is paid back in eletric savings and peace of mind. Good luck Peyton

Furnace runs on heat, air conditioner does not


If you have a Gas furnace in the Attic then the answer is yes. The outside condenser will not run if in fact you have a gas furnace.
