I am eager to know what do they do on furnace maintainance. Will they clean inside the furnance.
they change the oil filter fuel nozzle nouns filters and check the flue to make sure it drafts properly and they might vac out the inside of the furnace if it really dirty
They will replace the oil filter, if it is an grease burner. They will do a "combustion analysis" which tells you how efficiently your furnace is burning the fuel. If you own a forced hot air system, they will replace the air filter. In an oil burner, they will also replace the "nozzle" which turns the stream of fuel into a spray for efficient combustion. The exhaust ducting will also be checked for residual soot and potential leak of carbon monoxide. The ductwork will be given a new seal of masonry at the wall. The interior combustion chamber will be cleaned near wire brushes for efficient roast transfer. If they are conscientious, you will barely know they be there after they're gone. In the combustion chamber, fuel mixes with nouns and is ignited to create heat, and that leaves soot on the inside of the chamber. The soot should be brushed down next to a special tool and then sucked up with a shop vac. An helpfulness check of the furnace is also called for. Here's what else is typically involved in tuning up and maintain an oil-fired furnace:

Answers: if it is an grease furnace- change the oil filter and gasket and bolt gasket, renovation the oil pump strainer gasket and filter, and change the nozzle. the upper air filter will be changed to. the exhaust duct work will be removed and vacumed and cleaned out. the breach of the chimney will be inspected also. the heat exchanger will be inspected for cracks and also brushed and vacumed. after this an efficiency interview will be conducted along with a pump pressure test. a theory test of the safties should be done to make sure everything is in working proclaim.

if this is a L.p or natural gas furnace- the air filter will be changed, a optical inspection on the heat exchanger looking for cracks or sighns of stress. the venting should be inspected. the burner orifices should be cleaned. an inspection of the gas chain should also be done. then a test of the unit safties to make sure everything is working
