I recently booked air duct cleaning services through Superior and I can't recommend them enough. The onsite technician's were Heldr and Javier - they were quick and efficient and were more than happy to answer the various questions I had about the duct system, etc. as I just recently purchased this home. Heldr, the lead technician, went above and beyond during the service to ensure that the whole duct system was operating as it should. The past owners had neglected the ducts and some were completely disconnected, which Heldr remedied. He also walked me through how to access and change the filter on the furnace. We also happened to be having a new washer and dryer delivered today and the connection for the dryer was broken. Heldr stuck around for half-hour or so after the delivery to fix the connection and ensure that the dryer was hooked up correctly - saving me the time and headache of having to find another contractor. The teams knowledge and attention to detail is something I really appreciated and I will definitely be using their services again in the future. If you need air duct cleaning services, particularly in the Lakeview area, these are your guys.
