When my A/C system was making a bunch of crazy noises, I decided to have a good look at it.
I let the system run while observing the indoor HVAC unit, but that didn’t seem to be where the crazy noise was coming from.
Then I went to the outdoor A/C condenser and it was basically screaming with all these squealing noises, it was awful. I turned off the HVAC and cleaned out the A/C condenser unit really well. My brother taught me how to do this, but I didn’t always keep up with it. I got that HVAC unit clean as a whistle, but it was still making noises like it was stressing really bad. Then I realized something important, I had forgotten to change the air filter! I felt like a total idiot but at least I was able to swap the air filter out with a fresh one. I really must say that the air filter was blocked up really badly. I couldn’t believe that the HVAC system was working at all and still the A/C was coming out cold. Well, that solved the issue when I finally changed the air filter and the HVAC was actually running better since I had cleaned the A/C condenser unit. I’m glad I did that, but if I would have changed the air filter in the first place, I think the strange noises probably would have stopped with my A/C system. Still when the summer is over, I’m going to have an HVAC professional check everything out with my system and make sure to get a tune-up for my gas furnace.
