Hopefully you took advantage of this weekend's nice temperatures, and threw open the windows in your house.

The Environmental Protection Agency says that's important, because closed up homes and the extended use of our heating systems can cause a breeding ground for contaminants.

In fact, the EPA says indoor air quality is ranked among the top five environmental risks to public health.

Here are some tips to improve your home's air quality:

--Open the Windows
--Use Ventilation Fans.
--Change Your Furnace/Air Filter
--Have Heating/Air System Inspected
--If it Needs Cleaning, Hire a Professional  -- If the duct cleaning is done incorrectly, it can actually make the air in your home worse.
