Tech saw that my husband and I where sneezing a lot. He said I have something you might want to take a look at . That when he Introduced my husband an I to the Air Scrubber system an said let me show you what thus system can do. I was amazed at how something so small can help with allergies. He even went over the Nest thermostat. And took the time to explain everything he did while checking are system out. We highly recommend Jackson for any A.c. and heating needs you may have!
