Worst furnace ever!
Number 1 problem, the circuit board mounted on the fire box causes furnace to
malfunction; easily fixed by putting insulation behind the board. Number 2, when
you have to apologize to your neighbors because your furnace is making
too much noise, you're just not going to get much sleep at night. Avoid
buying this piece of junk.

This unit came with my new home and when it was 1 month out of warranty
(13 months old - can you believe that?) it required an $804 booster motor
and pressure switch. This company's 1-year warranty sucks, it pretty much
says how much faith they have in their product, and their customer
service sucks even more!
The service guy that came to work on it also said that the main blower motor isn't long for this world either, based on its extremely noisy operation.
If you have a choice, absolutely do not buy this piece of crap product! I know that once this unit becomes too expensive to keep running, I'll be very careful to never buy another product from Intertherm - ever!

This furnace was installed in our mobile home upon agreement to purchase
the home April 16, 2012. We have had problems with the switch #632453r
ever since the first winter season of 2012. To date, we have replaced
this switch for the fourth time; once in 2012, twice in 2013 and today,
November 1, 2014. There is a definite problem with this switch and Nordyne,
the manufacturer of this furnace, which is Intertherm, has to come up
with a solution. The furnace will not operate once this switch goes. I
have no alternative within my space to use any other kind of furnace. My
choices are very limited. I called Nordyne within the first year of
having this furnace and they told me it was not under warranty. The
documentation says one year parts and labor. I do not recommend this
furnace, simply because of this faulty switch that keeps breaking or

This unit is so loud the neighbors can hear it when it's running. We
installed a door down the hall where the unit is located, to try and
muffle the noise. Several months later we had a repairman come out and
service the unit because the vents stopped blowing cold air. The
serviceman told us we could not close the door we installed because air
cannot circulate through our house, and it is working harder to cool our
house. So we are still living with the loud noise it makes. I would not
have another one of these units if they were giving them away.

Not a Happy Camper!
I needed a new furnace in December of 2009. The company I used at the time replaced the old one with the same brand Intertherm M1MB-090*. I live in a mobile home, which only leaves me w/ a couple of choices. Ever since it was
installed I have said it did not heat as well as the old one. They checked the air flow & temperature & said it was up to par. It still does not heat as well no matter what they say. Now the bearings in the draft inducer motor are "Defective", that's what the repair man wrote. They said it would be $455 to fix. The part is defective for crying out loud. The furnace only has a 1 year warranty. I think this crap about having to buy extended warranties is for the birds. Make a good product, stand behind it, & quit gouging the little people!!!

Outdated and inefficient.
I have owned my furnace for eleven years now. It is an eighty percent propane furnace that has an output of forty-five thousand BTU's. I like it for the warmer heat that I feel when it comes on and for when the power is out, my small generator will run it with no problem as it uses gas for the source. I do not like the cost of feeding this furnace propane with the rising cost of fuel. I say it is outdated and inefficient in my title because there are newer and better gas furnace products on the market that can save me a larger chunk of change both in heating my home and in operating cost. I am neutral in my standing on it as I have only had to replace the thermocouple since owning it which makes it reliable but, I feel it does not adequately heat my home and is costly to use. I may buy and recommend the same brand only if I could get a ninety percent furnace instead by that manufacturer.
The M1 is available in different models which vary in efficiency and capacity.
