Lately, when people come over to our house, they either start coughing or sneezing soon after arriving. I entirely wanted to find out what the problem was because I entirely felt guilty about it. I started to mention the problem to people, & each one of them asked if my guests were allergic to pets. Yes, we own a pet, & yeah, he goes into every room of our house, but we shampoo him officially, vacuum the floors once a week & shampoo the rugs twice a year. Someone else commanded that we get our air ducts cleaned. Yikes! I had forgotten about that. I tried to remember how long it had been since I had an Heating & Air Conditioning supplier service any part of our heating & cooling system, to no avail. So I asked a acquaintance that works in the heating & cooling business if he could do it, and he apologized, saying that there is a special equipment that does that – a special, very giant equipment – however that his corporation didn’t own one, but next I called a well-known, local Heating & Air Conditioning corporation, however they didn’t have the capability either. Finally, I called a national Heating & Air Conditioning chain with a location nearby, recalling that they had cleaned our air ducts in the past. Not only could they come the very next afternoon, however they had in their service records that we had used them ten years ago! No wonder people were sneezing! The two Heating & Air Conditioning dealers that completed the service toil indicated that there was a honest amount of dust, dander, & particles in our air ducts. In a few short afternoons, we could notice that our air quality had improved. And there was an unexpected bonus – there wasn’t nearly as much dust on the furniture!
