Hello:

Son just moved into a house that has gas, forced hot air heating (in New
England)
The ducts are also used for A/C system where the condenser is mounted
outside the house.

Realize this is a pretty general question, but nobody in family has
ever had this type of heating system befo

How often is it a "good idea" to hire a duct-cleaning company to come
in and clean out all the duct work ?

In many if not most homes, it is NEVER a good idea for the home owner.
It is ALWAYS a good idea for the guys selling duct cleaning.

It sounds to me that it is time for you to have a competent professional
HVAC tech examine your system and make recommendations which may include
duct cleaning as well as servicing of the basic systems. Since you just
moved in it is not likely you have reliable information about their current
condition.

Can't know for sure, but it wouldn't
surprise me if it hasn't ever been done since the house was built 25
yrs ago.

I lived in a home for over 30 years and never had it done. Back then we
did not have all those outfits telling us we needed it done and funny, we
never suffered at all. :-)


BTW: how do they do this ?

Thanks,
Bob
