Last February, I had a problem with my gas oil furnace. Right around Christmas, it started making more noise than usual. I then observed that my modern home felt chilly. At first, I blamed the unusually chilly weather, but after turning up the control device several times, I realized the oil furnace was no longer putting out as much heat. I tried calling a few local HVAC corporations, but the timing was bad. With the Christmas holiday, they were all closed and charging higher fees for after-hours service. Since the oil furnace was still operational, I decided to wait until the holidays were over. Unfortunately, the performance of the gas furnace continued to deteriorate. The sound levels grew louder, and the amount of heated air decreased. Plus, the air odored unpleasant and there was swiftly a wonderful deal of dust blowing around. The oil furnace eventually quit altogether. Trying to get ahold of a maintenance professional between Christmas and New Year’s is just about impossible. I finally managed to get an appointment, and the specialist promised to show up between 10 AM and 4 PM. I can’t even imagine why the corporation couldn’t slender his arrival time down a bit. I spent all day without heat and waiting for him to show up. I didn’t dare take a shower, get groceries or even run the vacuum cleaner, because I was worried about missing him. The HVAC corporation finally showed up at 4 o’clock. By that point, my modern home was chilly cold, and I was aggravated. He didn’t apologize and didn’t offer to remove his shoes. While I was thankful he was able to maintenance the oil furnace, he left a mess behind and cost me a fortune.
