I have been using A1 Carpet Care for the past 20 years to clean my carpets. Depending on who they send, the results vary on how clean the carpets come out. I have seen them at their best and I have seen them not at their best. I have to say that even when they are not at their best, they are still better than other carpet cleaning companies I have tried. They have very fair prices and I have recommended them many times.
