Division Air cleaned my vents after renos and recently fixed my AC unit. I couldn't be happier with the service I received for both jobs. My general contractor said the duct cleaning was very detailed and said they took the time to do everything right. For my AC problem, Nelson checked everything thoroughly before providing a recommendation that will allow me to put off replacing my 12 yr old AC unit hopefully another few years. He's very knowledgeable and also took the time to explain how the system works which I appreciated being a new homeowner.
