Bringing home a pet is a real joy until you realize how much hair they shed into your HVAC system. I have two dogs, and after a year, I noticed more dust, worse air, and a strange smell every time the air conditioner came on. I called the greenductors for help. They did a full inspection of the system, cleaned the air ducts, and recommended installing an ultraviolet light to reduce bacteria and allergens. Honestly, it made a huge difference. If you have pets and have never had your air ducts cleaned, you're probably breathing fur more than you realize. Trust me.
