There is potential for accidents in every professional no matter the scope of work.
In the HVAC profession especially, there is potential for minor and at times very serious accidents.
On a site 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 very qualified HVAC techs but it was raining. The customer had requested that we purchase a new heating unit from the heating corp which we did. His old heating and air condition unit had malfunctioned just when winter was starting. The homeowner had explained that he had researched to find the most suitable electric heating system for her premises. She told us that she had looked at different central heating systems and decided upon the ductless HVAC that would be below the earth and would provide booth warmth and cooling in summer and winter respectfully. She also wishes to have the oil heater and space heater as she thought that since they were smaller than most units, they were easier to operate. We explained that though it was the case, these units were not capable of serving her entire home. As we proceeded to gig up the earth and do the boiler installation, the ground shook and the next thing I knew, I was laying in the hole with dirt all over me. There had been a landline and the ground had given way. I just got minor bruising but I was very shaken. Luckily this system did not need as much furnace/heat tune-up and so we proceeded to provide the pamphlet showing the energy saving help tips as well as the wireless thermostat.
