@OP:
While some sez that regularly air duct cleaning helps (? allievate any dust-related allergens, etc.), My experiences tell me that unless you've been using the cheepest, spun fibre-glass air filter in your furnace, otherwise: there's no need (IMHO) to do frequent air duct cleaning), so long as you are using decent air filter with filtration ability of MERV 5 or 7 or higher.
While I do understand the need for maintenance for any natural-gas furnaces,etc. fact is, as I can see that most high-end natural gas hot water storage tank heaters have their burner section sort of sealed, it leads me to believe that there's no need for frequent (once a year) servicing.... I would find a trustworthy heater technician (licensed) to do mine/ours once every 3 yrs or so, and will be fine.
Q.
BTW: most hot water storage heater (natural gas type) still uses pilot light, but with a piezo ignition to light it (with a sight glass sealing the bottom part of the burner section); whereas any recent hot air heater furnace (natural gas type) built/installed in the mid-80s are mostly mid-80s efficiency style with a hot element style ignition (no pilot lights). |
