David and his staff were very professional and efficient.  We were amazed at how much the RamAir System cleaned out of our ventilation ducting.  My family suffers from allergies and we felt that with David’s help our heating and air conditioner were not only going to be more effective, but also healthier.  During the cleaning, the noise was very minimal which was nice for our cat.  When the crew was finished they left our home free of any mess.

Our experience with David’s company- Guarantee  Cleaning  Services, Inc.  was such a positive one that I suggested hiring them to clean out the ducts in the office in which I work.  Our office had undergone a large remodel and was way overdue for an air duct cleaning.  David and his crew worked in the office during business hours.  The noise level was very manageable so that we were able to continue helping our customers without interruption.  Many of my employees had been having terrible allergies before the cleaning.  I have noticed a vast improvement  this  year and feel a large part of this is due to the thorough cleaning David and his crew performed with the RamAir System.
