I think it’s kind of funny how things can alter so suddenly. You can go to work and come home and doing this stuff has happened without everyone. Things break and things change and you are not even aware until you get home. Recently I got home from work and heard an exceedingly weird noise in my property. I actually thought someone was inside my home. I had checked the complete house and so nothing. I had to attempt to follow the noise. When I filed the tone I noticed it was from the HVAC unit outside. I know nothing much about HVAC units i absolutely had to call the HVAC company near my house. I made an appointment for them to come to my house to confirm the HVAC unit. When they open the HVAC unit they saw that there seems to be a missing fan blade. The missing fan blade will need to have come loose from the rewriter and was banging on other parts within the HVAC system. So the loose fan blade was making the different Noise Within the HVAC unit. What’s the fan blade fell off the noises had stopped. Luckily I had called my HVAC company to come consider it for me because it hasn’t been easy fix. If I had tried to fix it by myself I probably would have ruined it more. I am lucky that I’ve such nice HVAC professionals that are able to come to my house in addition to help me fix my system. The fan blade should not anymore be an issue.
