I have used other companies before Central so when I say that Central is the one that can provide the best service I speak from my true experience. The greatest difference I could notice, compared to the other companies, is the attention to details and promptness in their response> you never have to ask for the things you need, like please send me the invoice, or please arrive on time. With the previous company, I had to call them when they didn't show up at the house for the appointment! Central gave me a call the day before, and 10 minutes before they arrived to communicate that they were on their way. They are amazing!
