This people make me very unhapy because every time they coming here it is a new problem with my air conditioner unit. my air conditioner it is under guarantee but every time, I have to pay very expense a new bill, I'm low income person, with asma and disable. I paid to this company $4200.00 but only for the unit, but later I found down those people don't chance everything, now I stop a payment for $200.00 dollar because the heat is not working.
