I had not cleaned my duct system since 2004. We had recently completed some major interior renovations and afterwards found that the heating was not circulating properly throughout the house.
I called Dialone and was greeted by a very friendly and knowledgeable Josh, who not only allowed me to watch the process, but explained it too. He also pointed out some poor connections that were caused by my contractors and even remedied the issues by re-sealing my furnace and some duct work. Fantastic company, with no hidden fees and very reasonable prices. Being in investment real estate and owning many rental properties, I would definitely use Dialone in the future and also recommend their services to anyone else.
