For the past numerous years, I have been dealing with a persistent cough! I haven’t been able to shake it, plus I am tired of constantly being on allergy medicine. I finally decided to go to an allergy specialist plus he gave me an allergy test. After several hours of being poked plus prodded with needles, he gave me a list of things that I am allergic to. Some of the largest offenders were dust, dander plus pet hair. I asked the specialist what I could do to get rid of the allergens in our dwelling. He referred me to a Heating, Ventilation, plus A/C serviceman, however he told me that Heating, Ventilation, plus A/C appliances could be the number one cause for dust sensitivities. All of our allergens are hiding in our Heating, Ventilation, plus A/C appliance plus being circulated through our dwelling. I called the Heating, Ventilation, plus A/C serviceman as soon as I got back to my dwelling. He was able to see me that very day. He changed out all of our air filters, cleaned our HVAC ducts plus air vents, plus worked on our Heating, Ventilation, plus A/C system. Apparently, our HVAC ducts were incredibly filthy, which may have been causing our dust sensitivities to act up so much. I had no understanding that it was so important to have your HVAC ducts cleaned correctly. Normally, it is suggested that you have your HVAC ducts cleaned twice annually. But because our dust sensitivities are so sensitive, I decided to have him come back to clean out our HVAC ducts once per season. I am optimistic that having incredibly clean HVAC ducts will help our dust sensitivities a great deal. I also hope that this cough will subside. This is my last shot at avoiding going on allergy medication.
