If it seems like there is no place you can go to escape your allergies, even your own home, the problem may lie in your home's ductwork. Sometimes, particles that can aggravate your respiratory system find their way into the ducts that carry forced air or heat from your central air conditioning system to the rooms of your house. The result is a house full of aggravating allergens. Having your ducts professionally cleaned may be the answer to this problem.
When I had my ducts cleaned out last spring, the effect was shocking. I could breathe more easily almost immediately. Now my home is a refuge away from outdoor allergens, instead of a breeding ground for them. If you're having difficulty breathing indoors, ask your favorite HVAC professional if duct cleaning is an option for your home.
