Michael Petruccelli says Heating
Systems
Replace the filter in your furnace.
Consider having a heating
professional check your heating system to ensure optimal performance and
discover minor problems before they turn into costly major repairs.
Clean your ducts to better your
heating system's efficiency as well as to reduce household dust and to provide
relief to those with respiratory problems. Also check for air leakage
especially around joints.
Clean your thermostat's heat sensor,
contact points, and contacts. Check accuracy and replace if necessary.
If you act soon, you’ll minimize the
chance of being 200th in line for repairs on the coldest day of the year.
