Have a Question? Ask The Expert

  • Question: Question: My son was recently diagnosed with severe allergies to mold, pollen, and pet dander. Of course our main concern is his health, but we also have two dogs that are incredibly important to our family. Our doctor suggested we ask a HVAC contractor if there are any products out there that might help our son but also prevent us from having to give up our pets. Any suggestions?
