The people I was with and I had settled in my Grandmother’s household plus we were all so excited to be there! A group of us, her grandkids, had planned a surprise visit for the weekend. Everything was basically going good other than the fact that she punctuated every sentence with a cough which made me ask her when she had her Heating & A/C device inspected because it could be that her air quality was compromised. She actually admitted that it had been an entire year plus a half plus since everything was working great, she had no cause for alarm. I called the nearest commercial Heating & A/C provider who also provided residential Heating & A/C services to come plus check out her Heating & A/C device! The cooling specialist arrived the following day. After a thorough check she told us that the system of ductwork needed duct cleaning because the air duct was not as clean as it should be. The furnace filter was also terribly dirty plus was clogged up badly which could explain the dirt in the entire system. It also explained why granny’s cough had escalated a great deal these past weeks. The cooling device also needed air purification help which could work well with the washable filter to improve air quality in the household. My granny was shocked with all the labor that needed to be completed because she thought since she had a vacuum cleaner with a HEPA filter, she did not need common A/C servicing. After the professional left, the two of us did a major general cleaning of the entire household, even washed the drapes which easily catch a lot of dust plus other contaminants. We appreciated the rest of the stay plus the household felt much fresher than before.
