I had my ducts cleaned by Summit. I was so surprised when the technician showed me the amount of dirt and dog hair that was blown out of my furnace. It wasn't until a few days after my cleaning that I realized my furnace didn't make the weird start up noises anymore. I am now a firm believer in cleaning your ducts every year, especially if you have done any renovations or have pets. I also had my carpets cleaned by Summit another time. I trusted calling them to do my carpets since I had such a great experience with getting my ducts cleaned. I had stains that I didn't think would come out and the technician was able to do so. He even gave me tips on how to help keep it cleaned. I would highly recommend Summit. The whole process was easy from start to finish. The staff was kind and professional and they did an outstanding job.
