I am completely frustrated right now, and I don’t know what I should do. My Heating, Ventilation, & A/C plan is having serious complications, but it only seems to happen at evening. I have had a Heating, Ventilation, & A/C worker to our lake house on multiple separate occasions this week, although I can’t seem to make the concern happened during the day. However the Heating, Ventilation, & A/C plan is making some sort of weird clicking sound at evening only. I hear it almost every evening, as it goes on for multiple sevenths. By the time I have gotten up to grab our phone, the noise stops completely! After not being able to locate the problem, the Heating, Ventilation, & A/C worker asked me to take a sound video. I have had multiple different Heating, Ventilation, & A/C companies to our home, while neither a single one of them have been able to locate the sound. They asked me if it could be something other than our Heating, Ventilation, & A/C system. Although I can hear the sound coming from the garage, I wondered. It is as clear as a bell, and I suppose I am not crazy. The Heating, Ventilation, & A/C plan has been making this noise for 2 weeks now and I am utterly frustrated. I have called every service center in the phone book, however no one seems to understand the issue is with our Heating, Ventilation, & A/C system. I suppose that it is still working well, although I would really love to be able to locate the source of the different noises. I’m afraid that our oil furnace will split down in the middle of the winter, because I ignored a huge problem. And why do most people suppose that I am hearing things?
