I need another permit

Spring is near to its end and summer is coming soon.  I ask that anyone living with an elderly person or a sick person in their home to have preventative service done of their A/C system.  I am a certified heating plus cooling specialist and work for a large Heating, Ventilation and A/C corporation in the Deep South.  Many of my colleagues plus I have seen an unfortunate situation where the air conditioning of a home or commercial building failed and this  the failure resulted in the worst possible result that anyone could imagine.  That said, I’ve had friends call me to tell that their A/C is not sending the cool out through the air duct and ask me to check their Heating, Ventilation, plus A/C system.  I don’t really mind helping a friend, but I do have to be careful.  My employer, for the most part, is expecting me to get paid for Heating, Ventilation and A/C tasks that I perform.  After all, they sent me to school for Heating, Ventilation and A/C training to receive a certification.  I am a certified Heating, Ventilation, plus A/C specialist, not a handyman, looking for a few dollars.  My friends are under the false impression that if their A/C is not cooling their beach home to their preferred temperature control and that I can just stop by plus add some freon to get the thermostat to enhance the system and to cool the air. However, my boss pays for that freon, so anyone needing some must understand that this chemical is not free something that is often misunderstood.
