    Furnace Maintenance

    In your guys' opinions what is the most important part of furnace cleaning and maintenance you need to make sure is done right when servicing your customers heating equipment?

    Just wanted to pick other tech's brains alittle

    safety is the most important for the customer. reliability is most important for the tech, you don't want a blower motor failing 3 days later because you didn't check amps.
    you should ask for this thread to be moved into general or tech to tech.

    For me, its 2 things... Pull blower power lead and make sure your limit works, and check for flame change when blower is powered on. If its a hot water system, check limit, and the ALL IMPORTANT thing to test on steam system is the low water cut off. If that fails and doesn't kill the burners, the boiler can crack. If that happens after you were just there, best case, your customer loses confidence in you.

    Two things....

    FIRST: Run a combustion test... to verify the burner is SAFE and CO levels are within limits.
    SECOND: Verify all safeties are working as they should.

    BOTH are necessary... do not miss either on any furnace.

    The first and foremost would the the safeties which would be the high limit in furnaces. For a steam boiler it would be the low water cutoff...for a hot water boiler it would be the temp pressure relief valve. I know it isnt fun to open one and they don't reseat...but there is a reason and it's time to replace it !!

    Boy oh boy.
    How do you test the
    relief? Simply opening it doesn't prove much, in my opinion...

    I leave them alone as much as possible. Hard to imagine one stocking shut to the point of causing an explosion....

    Just the other day I let off some pressure on a 3 month old t & p valve, and it didn't reseat. Not dirty water, either. So annoying.
