The new house was so cool, however even though it was legitimately old, dating back to the late 1780s, it had been well kept over the yearsâ€¦ Some seasoned houses look ramshackle, however this 1 was quaint & classy. The only issue I had after moving in was with our flu symptoms, which seemed to get much worse in the new house. I am prone to flu symptoms anyway, so I take many weekly meds for it, however this was something I hadn’t encountered before. I decided the first step should be to contact a local Heating & A/C supplier & have them test our air quality. Two nights later a charming young Heating & A/C tech arrived on our doorstep with a satchel full of testing equipment. It took a few hours, because she did a thorough inspection of the central proposal & all of the ductwork, as well, then her results were conclusive – our flu symptoms were being exacerbated by a preponderance of rodent feces & hair in the ventilation system. She could find no traces of rats or mice currently living in the HVAC ducts, however at 1 point they had. All of the dander & germs they left behind were still haunting the HVAC ducts, & killing the air quality for the whole house. Since the rodents were gone, the Heating & A/C tech had a quick repair for me, because all I needed was a deep cleaning of the ventilation system. I actually hope she is right, & after the HVAC ducts & air vents have all been cleaned & sterilized then our flu symptoms will stop kicking our butt so hard.
