Guys were wonderful and professional! Great guys and a great company! Hear me out, if you have central A/C problem, call Coolair, never use Heritage because they are not only extremely expensive buy they are crooks! I had Heritage guy came to check my Central A/C and he tested and told me my compresser went but actually there were broken wires that lead to thermostat. He connected a couple of wires and the AC started right up! If the compresser is bad it could not be started! CoolAir guys installed brand new A/C but found out it was not working either until they found the broken wires in the attic and connected them. If I had called CoolAir guy first to check out my unit, I would have had saved myself thousands of dollars! Anyway I am very happy with the new unit because my old unit was 29 years old! Call CoolAir if you have A/C problem, they are honest and will save you lots of money!
