I replaced my air conditioner around 9 yrs ago and now I'm told it has a leak and I may have to buy a new one. I bought a Trane because I thought it was one of the better ones & I felt it should have lasted longer than 9 years. Does anyone know of a good reputable air condition repair place to get a second opinion. I'm told even if they find the leak there is no guarantee it will fix the job. I'm wondering if they just want to seek me a new unit.
