I just recently had my heater service company over for a cleaning
and servicing on my oil fired forced hot air system the other day. I
couldn't be present at the cleaning but within 15 minutes I received a
call from the technician saying that the draft reading was bad and he
thought my system should be replaced.

A 'draft test' was done with the -02 fan off and +01 fan on reading
lead the tech to tell me this. This was done before the heater was
either cleaned or serviced in any way. No nozzle change or anything. I
believe that due to scheduling conflicts last year my heater never got
serviced so I feel perhaps this complicated the issue. That plus it was
about 90 degress outside that day, and I think the techinician didn't
want the dirty job of cleaning out the furnace in those conditions.

Should I obtain a second opinion of this?, shouldn't have the
furnace been cleaned first and then readings obtained? The unit is over
25 years old and by rights has passed it's life expectancy but I feel
perhaps the tech may have taken the easy way out being I wasn't there
and he could charge me $65 and walk away without cleaning anything,
then an hour and a half of dirty cleaning and only charging me $125.

Any thoughts on this would be appreciated!

Thanks
