This is a recent Before & After from a Commercial Building. We were brought in for a Duct Cleaning and there was certainly an extensive build up of lint and dust. The customer was surprised by the amount dust that was removed and the air quality they were breathing in. Overall the customer delighted with the outcome.
If you suffer from household allergies, a duct cleaning may be in order. If you feel your A/C is no longer working as best as it could, dust and lint build up could be the culprit. A Duct Cleaning every 3-5yrs will keep your air quality and A/C unit in optimal condition.
