My father works as an industrial chemist.
His job pretty much is to mix chemicals to make various agents such as fertilizers for farmlands, medicine, or aerosols.
These chemicals are rather dangerous especially when inhaled. He works on a contract basis as well as the last corporation that he worked for, had a ductless mini split however it was totally neglected! As he mixed the chemicals he could honestly feel the chemicals settle on the surfaces of the lab although he had on gloves as well as a mask. The management had not performed even a single Heating, Ventilation, as well as A/C repair since it was installed so many years ago! My father, being experienced with these things, made a deal with the managers to have the heating as well as cooling equipment assessed by an air conditioning equipment rep so that it reached optimal levels. Cooling equipment workers from the property comfort supplier came to the lab the very next day as well as were horrified by the condition of the commercial air conditioning equipment. The quality air conditioner filter was entirely filthy with all sorts of pollutants including harmful chemical residue that everyone at the plant was breathing in. No wonder there had been so many cases where employees had contracted respiratory diseases. Other components of the equipment were worn out from years of neglect. The service professionals recommended replacing the equipment with a quality Heating, Ventilation, as well as A/C system, a hybrid Heating, Ventilation, as well as A/C system. They would easily embed a smart Heating, Ventilation, as well as A/C to improve its efficiency. All the needed components like the programmable control unit would easily be supplied by the local cooling as well as heating equipment corporation. The management of the chemical plant was certainly grateful to my dad for illustrating the critical importance of having an air conditioning equipment professional assess a unit often.
