We have used AlbertaPro Cleaning for nearly twenty years and have been very satisfied with them. We recommend them to everyone. I just had Martin, the owner's nephew, come out to my home to handle a major cleaning project. He showed up on time and jumped right in. He completely cleaned the furnace, the humidifier, all of the ducts, the vents, and totally sanitized the system. Everything came out wonderful! The technician was very very good and was very knowledgeable about his work. In the past, we have always had AlbertaPro Cleaning come out to clean our carpets and they do an excellent job every time. I think they are very professional and very trustworthy which is why we keep coming back to them.
