Hoping someone can toss me some advice...I'm pretty clueless when it comes to HVAC. Anyhow, I have a newish house (about 3.5 years old). I think my AC system is a split unit. There's the outside unit and another unit above my garage. Anyhow, the outside unit, starting about a week ago, is LOUD when it runs now. There's no screeching or odd noises...its just a lot louder than it was in the past. What could be causing this and do I need to call someone out to have a look at it? For what it's worth, it is working...house is warm.
