These signs indicate an AC tune-up in Pompano Beach, FL: Loud Noise: If the AC is making loud noises, there can be multiple reasons. However, the most apparent reason could be a loose screw, motor malfunction or dust collection, and bent blades. Warm Air: If the AC starts warming your room more rather than cooling it, checking the AC air filters might help. Due to dust accumulation in the air filter, the airflow can be affected. Unusual Smell: Dust-packed condenser coils can emit foul odours. When the AC gets turned on, it blows air over these coils, and because the rings are dusty, the air smells bad. Weak Airflow: The AC takes a long period to cool the room when there is an issue with the air ducts. Uneven Temperature: If the AC is fluctuating, it might take considerable time to cool the room temperature. So it's best to contact the specialists in this case.
