We had bought the house pre-owned one year earlier and evidently the previous owner had not had the system cleaned -- maybe ever. The contractor cleaned the system for about $150. It took him over 2 hours, and he did a good job. He suggested I install a UV light to make sure mold doesn't grow. He quoted me over $1000, and I thought that was way too steep. Since then I purchased a UV light system for $150 and installed it myself. I've opened the HVAC up a few times since I installed the UV -- no mold! I also have an Aprilaire air cleaner.

Where did you place the UV light?
