I am a fan of tplot crime documentaries plus will watch them for hours.
I am amazed at how well the law enforcers can sift out the evidence plus solve the cases efficiently. Occasionally I even see year-old cold cases solved from the evidence collected when the crime happened or current evidence. I understand that heat plus A/C products are essential plus used in a lot of areas in our lives although I had never thought that the police would use an air purification plan to preserve the evidence collected. Both of us received a call scheduling maintenance for the air purification system at the police station. The machine had been making unusual noises plus the indoor air pollen levels left a lot to be desired. The station needed to have the issue fixed before the plan broke down completely. Upon inspecting the system, all of us noticed right off the bat that it was covered in dust plus dirt. The air ducts were covered with all types of dirt plus debris. To get rid of the dirt. Both of us started the duct cleaning process which also included cleaning plus replacing the washable filters. Some areas of the air duct had come undone plus 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 wash the air filters after every few weeks to maintain the function of the air quality system. To finish off the locale task, all of us replaced the thermostat to a digital one that is easier to use. Both of us were escorted to the local supplier by a police cruiser that was heading to the supplier district for a welfare check on one of the supplier people.
