I was very happy with the service that Hvac Cleaning Technologies did at my home. The reason we picked them out of all the other companies other than their great review was that they specialize in cleaning air ducts and the equipment that they use to clean the ducts. I scheduled a lunch time appointment and liked the policy they have of having their techs call 30 minutes before coming out so that I did not have to wait around on them. Once they showed up at my home they did a walk-thru with me and explained exactly what they were going to do. After the walk-thru they got to work and made sure to be respective of my home and its contents. I was impressed when I did see in person the big vacuum truck in my driveway. After working 4 hours of cleaning they did a final walk-thru and let me know what they found during the cleaning and gave me some pointers for keeping my systems clean. Thanks for the great job.
