My name is Gary Harstad, I have been the President of GD Construction Inc for over 30 years. In the process of all the remodels we have done, one common factor we would always have to overcome was the heating and cooling vent cleaning and the systems commonly used out there didn't do as good a job as you would like. So we searched and discovered a company RamAir and I knew right away I would be a huge contender in the air duct cleaning business, and that I have done. Comet Air Duct Cleaning has earned a solid reputation and takes pride in knowing that we are undoubtedly one of the best commercial and residential air vent cleaning services in the Billings, Montana area
