I had a new wall furnace installed in my home 2 months ago. It makes loud popping noises everytime it comes on and off, for about 10 minutes. The heating company that installed the furnace told me this is due to the metal expanding during heating and there is nothing that can be done about this. They also said that this is a common problem with wall furnances. Is this true? The company has tried to loosen the screws to relieve pressure but this has not helped. Thanks for any info.

Ask the furnace people if it is viable and safe to put in insulation IE:Fiberglass between the outside doors to keep the banging down to a roar.

When a new gas appliance is installed. it's not a bad idea to clock it to make sure that it's running at what it's supposed to, gas-wise. In other words, you want to make sure that a 35,000 BTU wall furnace is actually using 35,000 BTU. This is done by firing *only* the one appliance & seeing what it's using on the gas meter, over a period of time (a minute or so will suffice). Most of the time it's right-on from the factory, but if it's over-firing - and this is adjustable - it may cause the symptoms you describe. Gas meters report usage in cubic feet, so you have to find out how many btu/cu ft your gas company is providing. Where I live it's 1050 btu/cu ft.
The appliance gas pressure can also be checked with a manometer. It should be within the specs of the wall furnace. That's also rarely a problem, but might be worth a look.
Worst case, call the manufacturer. There might be someone there that can suggest something.

It does not sound as if your heater is working properly. I had one in an old house that I lived in and though the thing was not quiet, it did not do a lot of banging and poping. If it were me I would call another heating company and ask their opinion. I would even try to call the manufacturer to see what they say. Bottom line is that you paid for it and you should be happy with your purchase and if you are not I would gripe until you are. I have found that a lot of times once a company has gotten your money they don't want to help you with anything else. I would complain until they fix the problem.

You definitely can remove the furnace. Get a few estimates from local plumbers (at least 3). A gas line can be capped off and have the opening sealed/drywalled to complete the removal. Because you are dealing with a gas appliance this should definitely be done by a professional. There may be inspections required by the city or county but the plumber you hire would be able to arrange that for you.

OMG, I am so happy you asked this question. I have the SAME problem with my wall furnace and it is driving me crazzzzzy. It's not that loud; I actually only notice it when the house is quiet and I'm going to bed. I was too lazy to look into it, but now that I see someone else is having the same problem, there's probably not much we can do :-(

Yrs. ago I worked in Heating & A/C . It could be your duct is to small to handle the air flow or pressure . The return air duct is collapsing inward & the supply duct is popping outward when the unit comes on & the opposite when it goes off . not much that can be done about it other than reinstall larger duct . The tech. is also right . Could be a combination . hope this helps you to understand .
