Periodically people will say better late than never. However, I suppose that late is sometimes too late. When I went to schedule my Heating, Ventilation & A/C tune up appointment it was too late. I had called & made an appointment. However, at this point it was already getting cold & the first snowfall was coming up suddenly. I could not get an appointment until the next week. I needed to turn the Heating, Ventilation & A/C system one because it had become significantly colder within a couple of days. I was definitely starting to feel it inside of my house. I wanted the apartment to be hot but, I could not get my Heating, Ventilation & A/C system to start up. This is when I knew that I should have requested the Heating, Ventilation & A/C system tune up much sooner. Now, I could have no heat in my apartment until the Heating, Ventilation & A/C professional was going to show up. When she did show up, she told me she had to upgrade some things. She had asked if the Heating, Ventilation & A/C system was working & I told him no. I could not get the heat to turn on. It turned out that the heating coil had burnt out & no longer worked. She had to upgrade the entire thing. If i had busy my tune up sooner, this might not have been an issue. It definitely tried so hard to turn on but it just couldn’t. I ended up paying some extra since it was going to be treated as a repair. I should have even busy a tune up in the Springtime after I used it. Maybe the problem could have been caught much sooner.
