My thermostat in my mobile home isnt reaching the temperature

On 2021-06-03 by (mod)

@Tj,

If you're asking about pressure on a heating system I'm assuming you have forced hot water heat. If that's the case then the typical system is at 12 PSI when it's cold and less than 30 PSI when it's hot.

If you have another type of heating system you'll need to help me understand your question.

@Maureen,

Indeed I would warn the customer to

Decorativefloor registers for supply ducts (C) Inspectapedia.com MaureenWatch out: their heating furnace is not operating at a normal temperature and worse, the system could be (and probably is) unsafe; it needs to be checked out promptly, and the customer should be sure that they also have working CO detectors and smoke detectors installed in the home.

Apologies for being so cautious but you understand better than many the importance of erring on the side of safety when we have so little information about someone's heating system.

For example, if the furnace high-limit switch is not working properly there could be a risk of fire or fatal carbon monoxide or smoke.

On 2021-05-11 by Maureen

We are a manufacturer of decorative floor registers.

A customer with a mobile home has reported a problem where the plastic damper box underneath our decorative metal register top (2 x 10" hole opening size) has melted.

The plastic will not become soft until 130 degrees, and it will melt at 170 degrees. I am confident that the temperature in their home is not 170 degrees.

If this was a regular home, we would suggest that a service technician should check the furnace, but we don't know enough about mobile homes.

I have an electric furnace in my manufactured home. Sometime the air will blow very cold for a really long time, the other day it took 10 hours to go from 52° to 68°. I changed the temp in very small increments to get it warmed and I had to set a small room heater in front of the door to warm the incoming air for the unit. We’ve had insanely cold weather here this week. I set the thermostat for 66° at night and I will wake up or come home to a 50° house. Why doesn’t the heat maintain the heat?

On 2021-02-15 by (mod) - Mobile home Electric heater takes a long time to start

George:

Listen at the heater: is there a humming noise that might tell us that a blower motor is not starting? If so turn off the heater and call for repair.

If there is no noise, tell me more precisely what's not starting: if your home has forced warm air heat (as I'm guessing is the case)

- is it that the blower does not start at all?

- or is it that you have electric heat and the furnace is very cold?

Typically a furnace has a LIMIT CONTROL SWITCH that will not turn the fan on until the heater has got sufficiently warm itself - to avoid blowing cold air on the home's occupants.

So if, for example you have an electric furnace and some of the heating elements are burned out or not coming on, you might see two symptoms:

- the blower takes a long time to turn on

- when the blower does run, the air is not very warm

That too needs repair by a trained service tech.

Let me know what you find.

Maybe normal for your heating system to switch on fairly frequently depending on the outdoor temperature and just how leaky your home is or in other words it's right of heat loss. On the coldest day of the year particularly when it's windy it's common for the heat to run a good part of the time.

We just moved into a single wide mobile home. The heat works great but it kicks on every 5 to 10 minutes or so. Is that normal or is there an issue?

On 2020-11-21 by (mod) - Combustion Air Requirements for Mobile Homes

Jan

Combustion Air Requirements for Mobile Homes

Watch out: as you may already worry, blocking combustion air to a heater can cause the production fatal carbon monoxide gas - you could be killed. Be sure you have working and properly-located CO and smoke detectors installed in the home.

Sorry to add that I don't understand enough of your home's layout and combustion air and heating equipment to be able to offer a reply that I'm sure is correct.

But in general, you must be sure that combustion air openings to your heater are not blocked and that the opening is sufficiently large and that if necessary the heater has outside air intake.

Just how many square inches of air opening that are needed depend on

- the type of fuel - oil or gas, for example

- the input BTUH of the heating appliances

- the design of any louvers or screens, as those reduce the actual effective size of the vent opening

- the tightness of the home: if a home is very air-tight then an outside combustion air source may be needed


Please see COMBUSTION AIR REQUIREMENTS https://inspectapedia.com/heat/Combustion_Air_Requirements.php

On 2020-11-21 by Jan

My mobile home has a furnace in the laundry area, with an entry door at one end and another door with a vent in it opposite of it. The door blocked the intake when it was open, so I removed it. When I replace it (opening the opposite way), do I need a vent in the door? Or louvers? Or is a regular door OK? Space is about 5x8' at most.

First, for safety be sure that your home has working carbon monoxide detectors properly located and tested.

Then ask your heating service technician to be sure that the burner is operating correctly as if it is not and if it is producing set the heating system is unsafe

What else would cause a house not being able to cool?

Indeed it's easier to blow cool air down into a warm space than to blow cool air up into it. But the floor vents can work if the fan and duct work are properly sized. It sounds to me as if your system is not doing a great job; have you had a tech look at the system to be sure it's properly charged and sized?

On 2020-09-16 by brandy

We recently bought a mobile home, it had a roof AC unit. There is ceiling vents and floor vents. The sellers put in a new AC unit but not on the roof and changed it to a ground unit. We have been having issue with the floor vents keeping the house cool as they have sealed up all ceiling vents.

They have ‘fixed’ all leaks that they could find. The house is 1450 square feet and has a 4 ton unit, brand new. If there is no more leaks in the duct work, is having floor vents good enough?

What else would cause a house not being able to cool? We live in AZ and we just went through the hottest summer with the temps above 110 and the inside of the house went up to 90. With the air running constantly.

Could your system be running in backup-heat mode? If so that would explain why it's hot.

If that's not the case, then turn off power to ALL of the equipment - heat pump, air handler, backup heat; if the system stays "hot" then I suspect a defective switch or improper electrical wiring. If that's the case the installation is indeed unsafe and needs an expert inspection and repair by a service technician or by an electrician.

Do keep me posted on what you find as that will help other readers.

On 2017-10-26 by (mod) - I can see the ground through the heating register in my mobile home

Jackie,

That suggests that your heating or cooling ductwork has fallen away from beneath the home. You or someone who can help you should take a look below the home.

If you can send me a photo of the vent and surrounding floor and then of a the view through the vent that would perhaps help me make other suggestions.

If you can, have an inspector look over the home for you. The cost will usually more than pay for itself by reducing the chances of a very expensive surprise.

I don't know a thing about the home you're looking at, but as an old guy who has inspected many buildings, when I see even one clear example of evidence that someone maintaining the home had no idea what they were doing, that puts me on alert to see what else they did.

Anon:

I suggest measuring the actual dimensions of the opening into which the metal frame fits, using that to define the physically biggest new unit you can buy that fits in the original wall opening.

Usually you can buy a physically smaller unit if it's BTU capacity is enough, then you'll need to block the remaining opening and seal it against wind and rain.

It may be more difficult to find a new air conditioner that fits exactly in the old sleeve. I'm reluctant to insist on that fit.

If you mean that the trailer electrical system shuts down when you are running the heat, that sounds UNSAFE to me - as if there is an electrical problem.

Are you using electric heat?

I would not run equipment that seems unsafe - instead you need to call a repair person. If your heat is electric, an electrician is the person you need.

Keep me posted.

We live In a dbl wide mobile home in florida. we almost never use the heat, however it got a litrle chilly the other night. We turned the heat on to take the chill out, as we have done in yrs past, but only cool air came out of all the vents.

We didn't even smell the usual "whats burning" smell that we normally smell when turning it on for the first time of the year.

It has been about a year since the heat was last turned on. Could this be a diy fix, or do we need to call someone? We left the heat on for at least 30 min by the way & still cold air.

There is a return for the hvac system in the hallway. I am replacing the carpet and would like to know if this needs to remain open with the vent cover or if I can seal it off. I have no idea what it is for and have no floor plan of this trailer. The previous owner recently past away, so I also have no one to ask.

On 2016-07-06 7 by (mod) - A/C system that's not cooling properly

Niki, I appreciate the frustration of having an A/C system that's not cooling properly, but we can't reliably diagnose the actual problem at your DW home by an e-text.

Problems range from crimped/disconnected/leaky (easy to fix) to under-designed or poorly-located supply and return registers or even an improperly-sized air handler. You want to understand the specifics of what defects your AC guy finds - and to see them.

That will make it easier to agree or not with any repair proposal.

On 2016-07-05 by Niki

I have a 1980 approximately 1500 sq. ft. DW that has a/c and heating ducts running from the ceiling and the floor registers are used as the return which lead to the air handler outside in the storage room with the filter being underneath It.

The system seemed to work well with a 4 ton 9 SEER York although you only truly felt the 2 floor registers nearest the air handler having strong suction and I believe the other rooms have 2" x 4" boxes underneath the floor registers and I don't know if they are all connected or not.

Problem is that now we upgraded to a York unit, 3.5 ton, 15 SEER, 410 freon system ( not sure what size air handler is in but we were told it matches) and we can not get the system to work properly.

My a/c guy thinks the return is poorly done and claims that is the problem. We have more pressure blowing from the above air vents on either end of the house but not much in the centre. I live in Phoenix, AZ and in the afternoons we ca not get the temp to go below 80 to 81 degrees and it runs constantly.

I am reading that the evaporate coils might need to be bigger, the lines may be too small and other factors could be the cause other than the returns that are in the floor. Most rooms do have 2 vents in the floor, the living room has 3, and it seems adequate although u only feel those 2 registers nearest the air handler having suction.

They found a big piece of insulation in one of them and we don't know if they are all connected or not. This is unacceptable for having a brand new system just installed.

Right now in the heat of the day it feels like it is blowing maybe 12 degrees lower than what the house temp is and that should be around 20. This is unacceptable. My a/c guy isn't giving up but now he wants to put in a new 16" return up on the ceiling.

He is coming by to show me what he intends to do and it of course will have to cost me some money. Is this the problem? I explained this pretty well and am hoping you might know if this is the proper solution or not.

Any other suggestions? I am about to call other hvac installers for estimates on correcting the problem. What do I want to hear to know who's going to get it right?

On 2016-05-30 by (mod) -

Doris,

If the A/C is weak at some registers I suspect the ductwork is disconnected, torn and leaky, or blocked, or your air handler for your A/C system has a very dirty filter that needs to be changed. If you search InspectApedia for "WEAK AIR FLOW" you'll see more on how to diagnose the problem.

If the air that is supplied comes out warm then your air conditioner is not working - could be out of refrigerant, or could be the outside compressor/condenser is not even running.

Cathy DO NOT block air flow to your heating appliance or you may cause it to produce fatal carbon monoxide due to lack of adequate combustion air.

You should not to kill power to an A/C system in winter nor a heating system in summer if you set your thermostats properly. It's ok to kill power anyway, but remember the risk that you're away from home and forgot to turn the heat on when freezing weather comes.

On 2016-05-13 by Cathy

I have two questions. My door to the closet where furnace is has a air vent on it should I cover it on the inside with a filter? My second question is during the winter when I'm using the heater should I turn the switch off in the electric box to the air conditioning unit and in the summer should I turn the heater switch off while I'm using the AC? My unit is a central air/heater combo. Thank you

On 2016-04-16 by (mod) -

Pam,

If you cannot light the pilot at all then I suspect that there is no LP gas, or no fuel, or a shutoff valve has been left closed.

If you can light the pilot but it will not stay lit then most likely the problem is the thermocouple. That is the flame sensing safety device. If the problem is the thermocouple, that part can be replaced.

Certainly I would not assume that you need to replace the entire heater simply to get it to work.

Be sure that any work done on your heater is buy a trained service person, as making a mistake could kill someone.

I have a 1980s single-side mobile home, with a Miller CMF 80 PO-CONV furnace running oil.

The limiter is brand new (installed less than four hours ago), the relay is just over one year old, and the sensor is clean and functioning (tested with a multi-tester).

I am having issues with the furnace coming on, but shutting off BEFORE the fan switches on.

Current settings on the limiter are 90/110/160. My home also has a Coleman AC unit which is controlled by the same thermostat, and I am reasonably certain that a replacement thermostat that I installed a few years ago is correctly wired (I followed the markings from the old non-timed unit to the new RiteTemp 6025 unit.

I have the two T-lines running from the furnace to the W and RH contacts on the thermostat

. It is possible that I have the AC connected incorrectly, (were connected on Y and RC contacts on thermostat) but unless this is an essential part of the process of getting things right, that is a low priority at the moment. I am unsure of where to go from this point.

Reply:

"Violation" is a tricky term Sandra and Anon as building code enforcement is ultimately up to local building officials.

More confusion can arise because mobile homes, often built by manufacturers who assume their products must comply with building regulations across multiple states or provinces, build to model codes, and local building inspectors, knowing this, may not feel compelled or even able to inspect such homes for local code compliance.

Question: use a residential heating furnace in a manufactured home?

(Jan 30, 2014) Ray Cole said:
Can a house residential furnace be used in a manufactured home

Reply:

Ray,

if by manufactured home you mean like modular housing, not a MOBILE home (trailer home) then yes.

If you mean in a trailer home like the types shown in this article - it depends - on equipment size, space requirements, btu requirements etc. The heater must meet the required HUD specifications.

If you have a specific brand and model in question let me know and I'll research the specifics.

Certainly because space and combustion air and btu requirements are often different for a mobile home like the ones discussed here, we expect to see heating equipment designed for safe installation there.

I'd be very wary about just hooking something up without knowing the specifics as you could risk burning the place down or dangerous carbon monoxide hazards.

(Nov 4, 2014) Anonymous said:
to Ray Cole: No you can not use a residential furnace or air handler in a mobile home. mobile homes are under HUD guide lines. In the installation instructions of residential systems spells this out. most heating systems for mobile homes are down flow and Coleman, Intertherm, Mortex make mobile home heating systems.

However, If you decide to replace the system with a package unit they are compatible as long as they have a high static blower system.

Mobile home duct systems are not design to maintain pressure the further you get from the source.

Question: some rooms in doublewide don't get adequate heat

(Oct 4, 2014) Kathy said:
I have a double-wide built in 2000, my bedroom and bath are in the back of the house and is always so cold from October through the winter/ spring months. The heater is in great condition and I have had an inspector from the gas company check for heat loss, but it hasn't helped

. Could there be a problem under the house with the ventilation pipes and how much would something like that cost to get inspected?

I have had electric heaters in those rooms since I bought the place newly built for me. I have also had the company that built the house come out, but I think they only checked the inside.

Reply:

Kathy

The least costly first step might be to ask your heating service company to check for a disconnected or blocked heating duct or a closed register or duct damper.

The check needs to include a complete survey of the ducting, including under the unit.

(Nov 4, 2014) Anonymous said:

Kathy, with double wides typically the heater sets on one half of the home and has a crossover duct to the far half. If your cold rooms are on that far half the air flow and temp is greatly reduced by the time it gets to your rooms. the easiest and first step is to regulate the supply grills on the half the heater sets on.

Cutting almost off any bathrooms (usually the hottest rooms) if the grills are broke replace them, next regulate to at least half off all rooms closest to the heater.

If this does not get the desired results, I would inspect the cross over duct. It should be dead center of the furnace and at least 12" supply. also you can put a scoop (small piece of metal in those vents in the colder rooms to deflect air up. Lastly I would check the seal around the connection of the floor supply boot to the main trunk line it is where to pieces of metal duct join and reseal with foil tape.

I live on a double wide mobile home- have an electric air conditioning/heater system. Couple days ago the heater was working and now it does some click noise like is going to come on but do not come on. What could be the problem? Thanks

Reply:

Robert,

It sounds as if you have a heat pump that's not working. See the diagnostics at

inspectapedia.com/aircond/Air_Conditioner_Wont_Start.php

If outdoor temperatures are too low for your heat pump to provide heat the problem could be failure of your backup heating system to operate. Look for a control board or relay failure.

Question: Triplewide home does not get enough heat in some rooms

(Mar 13, 2015) Ruth Cameron said:
we have a 1997 triple wide and our issue is that both the back bedroom air don't seem to be have any air or heat coming out and we really don't understand why.rest of house is cool or warm depending on season.

we have tried to find blue prints of the duct work thru the manufacturer but have been unsucessful, we really didn't want to go to the expense of someone checking it our and telling us that it all needs to be replaced and that it would be very expensive,can you shed some light on this at all.help is very much appreciated

Reply:

Ruth,

If you are getting air and heat out of some but not all registers then it's not likely that the heating system itself needs replacement. More likely is that ductwork has come disconnected or become blocked somewhere.

On a triple-wide usually the HVAC ducts are on the underside of the unit. It's worth getting someone with a clear mind and a good flashlight and some knee pads and maybe a helmet to crawl under there to take a look. Not only are you not getting heat in some rooms, but you may be wasting that very heat by blowing it onto the mice under your home.
