Things are not good around my home

I prolong getting furnace and A/C tune ups. I literally wait as long as I can before I make the call. Having an oil furnace and A/C supplier come into our home is the worst. I would rather run errands all day than have the oil heater and air conditioning worked on! Once a year though, I grit my teeth plus do it. Then why do I do not like heating and A/C tune ups so much? The oil heating and central A/C provider that I use only comes during company hours! That means I have to waste a day off from my job to babysit the heating and A/C company. They never provide me with an exact time either, and so I need to wait all day long for the Heating, Ventilation plus A/C provider and just hope he shows up. Sometimes the guy shows up way outside the time window they gave me. There are times the HVAC company just does not come. Once I get the heating and A/C serviceman in our home, it is worse. I have to hang around and babysit the guy. I make sure he takes off his shoes or covers them before walking on our carpets. I then make sure he genuinely cleans our heating and cooling equipment. If I am not right there, the HVAC contractor skips through all his steps. Sometimes he does not even change the air filter or dust inside the system. So I sit there for 1-2 hours making sure he genuinely does his job. After the job is done, I then try to get the guy out of our home and pay through the business, not him. I have gotten into some sticky situations with that before. It is just a real pain in the butt.
