What affects a Wisconsin heating bill more than clean ducts?
Heating a house through a Wisconsin winter is a big job, and most of the savings come from keeping the heat you make. The usual suspects are leaky or uninsulated ducts running through attics, crawlspaces and unheated basements, air leaks around the house, a clogged filter, and a furnace that is past its best. A licensed heating contractor can check the furnace and test ducts for leaks. Wisconsin’s Focus on Energy program publishes guidance on home energy upgrades, and it is worth checking what is currently offered.
Can anything inside the ducts hurt airflow?
Yes, though it is usually simpler than you would think. A dirty filter, registers blocked by rugs and furniture, closed-off returns and heavy debris at a register or return can all cut airflow and make the system work harder. Start there: change the filter, make sure every register and return has room to breathe, and look inside a few registers with a flashlight.
When might cleaning help?
If you find heavy buildup of dust or debris, or construction material after a remodel, and especially if some rooms barely get heat, cleaning may help restore airflow. A camera inspection can show whether there is a real obstruction before you spend anything on cleaning. If airflow is still poor afterward, the problem is probably somewhere else, and that is a question for a heating contractor.
Common questions
Will duct cleaning make my furnace last longer?
There is no solid evidence of that. A clean filter, a yearly furnace check by a licensed contractor and good airflow matter more for furnace life.
How often should I change my furnace filter?
Follow your furnace manual. Many homes change a standard filter every one to three months during the heating season, and sooner with pets or heavy dust.
Do dirty ducts make the air conditioner work harder?
Heavy restrictions can reduce airflow, and that can make any system work harder. Dirty evaporator coils and filters are more common culprits than the ducts themselves.
Should I seal and insulate my ducts instead?
If your ducts run through unheated spaces, sealing and insulating them can matter more for your bill than cleaning. A licensed heating contractor can test for leaks and advise.
