Allergy sufferers may have some reprieve during the rainy times, but as spring approaches and more plant-life blooms, there are a variety of things that may be ready to attack overactive immune systems.  Changing your furnace filters and keeping your ductwork clean (it’s recommended that homeowners clean their ducts every year or two) can help cut down on indoor allergens.  And don’t forget about carpets, either!  Regular vacuuming and a deep cleaning a couple of times a year will help, too!
