I am a fan of true crime documentaries and will watch them for hours.
I am amazed at how well the law enforcers can sift out the evidence and solve the cases efficiently.
Sometimes I even see year-old cold cases solved from the evidence collected when the crime happened or new evidence. I understand that heat and AC products are essential and used in a lot of areas in our lives but I had never thought that the police would use an air purification system to preserve the evidence collected. We received a call scheduling maintenance for the air purifier at the police station. The device had been making weird noises and the indoor air quality left a lot to be desired. The station needed to have the issue fixed before the system broke down completely. Upon inspecting the system, we noticed right off the bat that it was covered in dust and dirt. The air ducts were covered with all types of dirt and debris. To get rid of the dirt. We started the duct cleaning process which also included cleaning and replacing the washable filters. Some areas of the ductwork had come undone and needed duct sealing to preserve the temperatures within the lab. Fortunately, the heat pump was functioning well. The maintenance crew at the station knew to clean the air filters after every few weeks to maintain the function of the air quality system. To finish off the site job, we upgraded the thermostat to a digital one that is easier to use. We were escorted to the local business by a police cruiser that was heading to the business district for a welfare check on one of the business people.
