It could be the motor.
It could be the drive shafts and ball bearings.
But it doesn't matter because the welds on the 30 year old monster are starting to "go."
I've been doing some research--and lo and behold, the Federal government has an EcoEnergy program designed to encourage homeowners to make upgrades to their homes in the name of energy efficiency. Depending on the kind of furnace we purchase we could be eligible for $300 to $500.
However.
In order to qualify, you have to enroll in the program. In order to enroll in the program you have to have an "energy assessment" completed. (We had one done in 2002 --it's too "old" to qualify. We paid $100.00 for it.)
I have called three companies and was only able to get a quote from one of them: $275.00 for the initial assessment and $99.00 for the follow up. (AND they are unable to even come do the assessment until Oct 23. (brrrr.))
eh?
The city we live in has chosen to match one of the federal grants. If we
Replace [our] furnace with an ENERGY STAR qualified furnace (that has a 92.0% annual fuel utilization efficiency or better, with a DC variable-speed motor
then the city will match the $500 federal grant. So, we may come out ahead by $600.00 ($1000 minus the inspection/program fees.)
So, the next thing to do is find out how much more a furnace like the above costs vs. the other furnaces listed as eligible for the federal rebate (but not the municipal rebate, though come to think of it, given the fees, it isn't worth it) vs. the medium grade clunker required by building code.
The husband is of the opinion that rebates tend to artificially inflate the cost of the item in question, and he's likely right.
I never once imagined that I would ever turn away from a "free" $1,000.00.
Nonetheless, the rebate program also covers things like replacing hot water heaters and installing insulation in the attic and basement (and other stuff). Total possible eligibilty is $5,000. But, you can only apply once--which means if we want to maximize the rebates available to us, we have to
all the work within an 18 month period.
So, guess who shouldn't have taken an expensive family vacation this year?
