How necessary is it to have an annual diagnostic check for a gas furnace that
was new in 1989?
The company that put it in hits us up for $100 a year for this. My neighbor
said he pays less for a similar check on his oil furnace. It was his opinion
that mine should be cheaper because a gas furnace is simpler.
Lets face it, 1989 was some yrs ago. I always have my system gone over
twice a year, I had a new system put in last year and had it serviced twice
this year. Maybe I over do it, I dunno.
If your neighbor knew so much about furnaces, he wouldn't be having someone
service his. So, he wouldn't know a whole lot about pricing. Sounds like
your neighbor is the simple one :o)
The standard now is over $100 for a complete checkout. Unless your company
is actually checking, and not doing what we call a drive by, where they come
in, twiddle around a bit, and charge you, but really checking it out, like,
gas pressures on the valve, diagnostics for cracked heat exchangers, all
safety switches checked, then get a new company.
An oil burner, by the way, is just as simple, if not more, than a gas unit.
Both have to have pressure tests, both have to have combustion checks, both
have to have heat rise checks, both have to have the SAME checks. Parts of
course are different, but I would rather work on oil all day long.
And, I have to say, oil is MORE expensive to tune and check...and
But...if hes getting a check for under $100 on an oil unit, he is for SURE
getting a drive by.
Yeah, a hundred $ seems a bit much for a furnace check. Hard to tell if the
technician knows what he/she is doing or not as they just say everything is
OK. I would call around to compare prices. Better to know whether you are
being overcharged than to go on wondering about it.
I have a 28 year old gas fired hot water heating system and it has never
been checked by a furnace guy. I don't think many of them know anything
about hot water systems anyway.
I turn off the pilot light in the Spring at the end of the heating season
and vacuum out the area where the fire is. In the Fall, I relight the pilot
and check to see that the furnace burns with a bright blue flame. No
problems so far.
