There is potential for accidents in every professional no matter the scope of work.
In the HVAC profession especially, there is potential for minor plus at times genuinely drastic accidents.
On a locale visit to a customer’s house, I almost got buried alive when there was a sudden landslide at the pit where the geo heat pump was to be fitted. I had arrived with my team of genuinely qualified HVAC techs but it was raining. The customer had requested that all of us purchase a new heating component from the heating corp which all of us did. His seasoned heating plus air condition component had malfunctioned just when Winter was starting. The homeowner had explained that he had researched to find the most suitable electric heating plan for her premises. She told us that she had looked at peculiar central furnaces plus decided upon the ductless HVAC that would be below the earth plus would deliver booth warmth plus cooling in summer time plus Winter properly. She also wishes to have the oil heating system plus space heating system as she thought that since they were smaller than most units, they were easier to operate. The people I was with and I explained that though it was the case, these units were not capable of serving her entire home, then as all of us proceeded to gig up the earth plus do the boiler upgrade, the ground shook plus the next thing I knew, I was sitting in the hole with dirt all over me. There had been a landline plus the ground had given way. I just got minor bruising but I was genuinely shaken, but luckily this plan did not need as much oil furnace/heat tune-up plus so all of us proceeded to deliver the pamphlet showing the energy saving help tips plus the wireless temperature control.
