The inside of your house may look clean, but an invisible problem can pose some of the biggest health problems to you and your family. Dander, dust, mold and harmful chemicals pollute the air in your home and also hinder your heating and cooling system from functioning efficiently – wasting energy and money. 

If you want to improve your home's air quality, we recommend that you do the following: 

• Clean HVAC system – You will need to hire a professional technician to clean your HVAC system and ducts. As you spend all of your time at home breathing the air that this system puts out, keeping it clean and professionally maintained is one of the best things that you can do for your health. 
• Keep areas ventilated – The simplest way to do this is to open your windows every once in a while. You should also use the exhaust fan in the bathroom, and in the kitchen use the stove hood when you are cooking dishes that create excessive steam or oily vapor. 
• Mold testing – Mold is one of the most harmful air contaminants and can cause serious respiratory problems. To prevent it from forming, regularly clean areas where moisture and poor ventilation meet, like behind the refrigerator. You should also hire a professional to perform an inspection for mold. 
• Replace screens and filters – You should regularly check and replace the filters in your air conditioning system. Dirty filters can circulate dust around your house. If you use screens on your windows, you should clean them and remove large particles and insects.
