Have you ever noticed that we tend to ignore minor problems until they get out of hand? That was the case with my air ptac cleaning services. At first I thought the drop in performance wasn't a big deal, maybe it was just the heat making it work harder. But then it got worse. The air flow decreased, strange noises appeared, and suddenly it stopped cooling as before. After doing a little digging, I realized that it wasn't the unit itself, but the dust and debris that was clogging it up. I finally contacted professional ptac cleaning experts and let me tell you, it made a difference. The unit is running like new again and I didn't have to spend a fortune. Don't wait for things to break. Regular cleaning can save you a lot of trouble in the future.
