 Since April. But, you know, when you deal with an insurance company, it is what it is. But if you're not dealing with an insurance company, my point being, you need to contact Pure Air Consultants if your air goes out today. Ever wonder why your AC stopped working? Well, the common reason is little issues like a flip switch, a dirty condenser, an improperly sized unit, an old unit, or a malfunctioning thermostat. Man, I wish those could be my problems. It's always a compressor.
