    Your test result numbers are way off. I bet the noise is on start-up with an 8% C02.
    The blower probably needed new bearings and shaft if it is belt drive. Many newmacs were beltdrive back than. BTW...

    Homeowners beware. Any contractor that does not do a heat loss or heat gain should not be installing equipment! We are wasting so much of our natural resources by oversizing equipment and nobody...

    I would guess your boiler is 5 times over sized. Big waste of fuel. Rip it out the first sunny day and replace. A good 85% or mod/con is good with OD reset with either decision. One you know the heat...

    As Beenthere stated the hard part if this is a cast iron boiler will be boiler protection. The resistance will be low in your system. Usually the circulator that came with the boiler is enough flow....

    I really doubt this is an air problem. It may be a flow issue. I assume this only happens at higher water temperatures. How much fresh water is being added to the system? Turn off the make-up water...

    The fuel consumption will be increased with age due to an efficiency decrease but the actual btu output will not change much. There is no reason to add anything to the heat loss to cover this. There...

    If the unit was installed in the seventies I am sure it is over sized. Out of the existing heating equipment I would guess there is maybe 5 or 6 in this great nation that might be properly sized....

    Unless you want to, I would not change the radiation. Do the heat loss and determine the amount of radiation as compared to the heat loss at hot water temperatures to see if the radiation is large...

    What makes you think any company would change the ductwork for free. There is no Obama care for duct systems.
    I think what everyone is saying is that what ever you do other than fix the ductwork,...

    It is all about the boiler being sized to the radiation and not the existing boiler. The near boiler piping is critical. NO cutting corners here. As stated before you need a contractor that knows...

    The units also sound too large for me. 9 ton of cooling for about 4800 sq ft. Maybe put some glass in holes which used to be windows to reduce the heat gain. Just kidding of course. I have seen many...

    What are the control settings. There should be a low limit, high limit and a differential setting.
    The coil should be able to supply you the rated gallons all day long.
