I inherited an air cleaner and brought it here because I thought they had free yearly check ups, but that is only for the first couple of years of certain vacuum cleaners. Still, I had them do maintenance on my air cleaner since I was somewhat unsure of it’s recent history. They cleaned it up, changed out the oder filter and I was out the door. The vacuums and air cleaners are on the expensive side but the maintenance charges are about the same with any model you might have. The staff at this location is top notch and very helpful.
