When I had my usual Heating and cooling tune ups I had no idea that it was going to end badly. I have my heating and AC system to have done every six months. I do this to ensure that my heating and AC system stays in tip top condition. What I never planned on was that somebody would get injured while trying to maintain my heating and cooling system. It started out as a normal day, I had my HVAC appointment that day and the heating and AC guy came out to perform the maintenance on my heating and air conditioning system. It was nothing out of the ordinary always going well until about a half an hour into the maintenance job. All of a sudden I heard the HVAC system worker scream. When I heard this I ran out to check on him and see if he was okay and I saw that he had injured himself while repairing the heating and air conditioning system. His arm was all cut up and he was bleeding, okay I had some bandages from a first aid kit in the house and I helped him mend his wound. It wasn’t a serious one not anything that would require a trip to the hospital but he was able to finish the heating and AC job as a result of the injury. I didn’t mind too much I just wanted to make sure that he was okay, I could always hire another heating and AC worker to come and fix my HVAC system anytime. This just goes to show that people that are not professionals shouldn’t work on heating and AC systems, because if even an HVAC professional can make a mistake every now and then imagine the amount of mistakes someone that doesn’t know what they’re doing could make.
