Terrible company, terrible customer service. it took almost two months to get my AC unit replaced. Thankfully i am not elderly or have a baby. They are hard to reach and don’t get back to you. I talked to them on a Friday and she said she would call back after lunch, never called me so i had to wait again until Monday to be able to reach them. After finally scheduling an appointment and me taking off work to be home, i called them 30 minutes after they didn’t show up to my scheduled appointment, where i was told that they were planning on calling to reschedule for the next day??? Meaning they expected me to take off work two full days, one day without notice. No apologies, no compensation, no compassion for having no working air conditioning during some of the hottest days of the year. Fortunately every service man i dealt with was wonderful and professional, however the women working the phones aren’t. Terrible company with terrible customer service and i would never recommend them to anyone.
