People say that HVAC specialists advise that ductwork be cleaned time to time. I have noticed that my air conditioning does not run as efficient as it once did, and I wondered if it could be an issue with my ductwork. Regrettably, it being the middle of summer, all of the HVAC companies I have called to schedule my ductwork cleaning have said that they cannot fit my appointment in before the end of the month! I was quite shocked that I must go so long with my own possibly-dirty ductwork. I called quite a few companies, and not one of them could fit me in. I was very worried that by the time I could get the help, I would not have time to have an HVAC contractor come by. When school starts back, I barely have any amount of time in the day to get my own papers graded, my house cleaned out, and dinner cooked. I certainly would not have time to spare to keep an eye on an HVAC repair guy contemplating my ductwork. If I were a more confident person, I would take a look my own ductwork and see if it looked dirty. Sadly, I would have to climb up into my attic. Last time I went into my attic, I found a great deal of dust, spiders, and various creatures. I am not about to return into my attic. That is why I want to pay an HVAC contractor! If I am not able to find someone to come by soon, I am just gonna have to wait until next year to allow someone look at my ductwork.
