So the house does not smell of the cooked food after your done cooking.
Whenever a exhaust type work is done where something is replaced, it always smells like that for awhile. Eventually it disappears. It's done that on my vehicles.
I heard that you should have ducts cleaned but I don't know how often. How often should furnace duct cleaning be done and how much does it cost?
Yes. A car can run without an exhaust manifold. It will burn out the exhaust valves in the cylinders a lot faster than normal, but it can be done.
You bend over the object and breath in through your nose and then pass out.
It can be done.
With the information provided, I would say no, not for a novice. But it can be done. A new furnace would be cheaper than my fees to change it...pkazsr Elementshvac: Ask your heating contractor for a Green Ecm motor upgrade. We install quite a few of them. It essentially converts your furnace fan to a DC variable speed furnace. http://elementsheating.com
Check your furnace fan. The air conditioner unit can be running but the air circulation is usually done with the fan on the furnace. If you have a fan switch on the thermostat, check to see if it is in the auto position. If it has the settings on/auto/off, you can switch it to the on position and see if you get any air movement then. If not, you could have a broken belt.
If the leak is against the head, it can burn tracks into the exhaust port faces as if done by a cutting torch.
