This answer is only if you do not have a gas furnace. I have had several customers with brand new homes and units with black soot everywhere. One even tried to sue us even though the system we installed was all electric. Well it turns out they each were burning candles in there home. Yes candles. Our builder hired an independent inspector. The candles all came from the same name brand department store.

Is this an older gas heat unit? If so, you may have a burnt out heat exchanger, this can be dangerous.

Soot is a sign of incomplete combustion. Cleaning may or may not fix the root cause of this, and given the age/efficiency of the unit, I recommend replacement. If you do have it cleaned, be sure to have the combustion checked.
As to whether this is a DIY project is dependent upon your personal skills, but the fact that you asked is (sorry) a strong indication you should not attempt this job yourself. Hope this helps.

Black smoke coming from heater vent?

Hi, propane heaters are very well known for Sooting up. If the gas pressure is not correct on the MGV, this will cause the heater to soot up fast. You will need to have the inlet and manifold gas pressure checked at the tank and heater. This furnace has to be cleaned up!! You will need to call out a tech to check the inches of water column.

Hi there my home is about 3 years old. i have noteced black dust on the doors window frames basically everywhere. i don't know why.

Does this unit have an blower? If so there is no filter and this can happen.
Direct vent means no open flame in the house but you might still have a combustion problem. Open the front cover and check for black soot. Also check outside at the flue for soot. If so then you need to get this thing checked. Also make sure the little door for the pilot is closed. May have a improper install here if only 3-years.

Creating soot in house

Sooting is general caused by incomplete combustion. Which, most of the time is caused by a dust, lint and/or pet hair build up in the heater. It clogs the burners , as well as the air intakes. Thoroughly cleaning the interior of the heater and it's inner workings will generally solve the problem. Also, an less frequent ... low gas pressure to the heater can cause sooting. Burning scented candles while the heater is in operation contributes greatly to the soot problem and indoor air pollution.

The above should help you to further troubleshoot and solve the soot problem.

My natural gas heater is putting black soot out all over my walls and ecerything else. Could you tell me what the problem is and what to do about it?

It needs a service asap soot gives off fumes do not use it , It could be blocked air ports on the burner , burner blocked , blocked injector , burning at wrong presure , blocked flue .

Any of these but get it serviced this will all be checked when you have it done .

Furnace filter is black and sooty wall seem to be sooty

   By sealed unit you mean that the burner air comes from outside of the house?      You have checked the heat exchanger for cracks by removing the burners and looking with a mirror and flashlight, correct, or had a service tech so?
The furnace burners have enough air and are burning clean (blue) with just a tip of orange at the end? You bought the house new and the fireplace has never been used?  If it has been used to clean smoke for the house for whatwever reason I woudl start by havign the ducts cleaned.   Another possibility I have seen is insolation inside of ductwork breaking down.

Dryer body very hot, loud squeking, soot from ball in back

I would replace the high limit control and the thermostat to be on the safe side. There is a real danger of burning the house down.
