NEVER EVER USE ADVANCED FURNACE AND AIR DUCT CLEANING Bayville NJ. They did a horrible job on cleaning my system. Had to come back to clean the humidifier which had mold in it, then came back today to redo my ducts and said they'd clean my furnace coils. The tech came and redid the air ducts but did not clean the furnace coils because a woman at the office told him to not do it because I refused to pay AGAIN for a job that should've been done right. They then called the police on me and sent them to my house. Cops showed up and basically laughed. So they send a different tech out to clean my furnace coils. I turn the heat on and my furnace caught on fire. Not sure what happened but never ever again. Be careful who you hire for a job.
