I was contacted by ARS to schedule my annual heating system check-up. Clifford showed up when scheduled and did a thorough inspection after which he recommended the air scrubber for the unit which will help keep the household air free of germs, bacteria and viruses. He assisted me with the 11 month interest free financing and explained the system well. I had been considering filtering systems for the house, this one will fit the bill! In addition, Clifford was friendly and professional, great service.
