Numerous ads finally prompted me to phone Johnny On The Spot (JOTS) to get a free estimate on a new a/c unit for my 18 year old Henderson home. Within one hour of my call to Dina, Joel Ramirez rang my doorbell. Joel spent the next 30+ minutes examining my current equipment and carefully explaining all my options about replacing my 3ton York equipment with a 4ton Trane system. I told Mr. Ramirez that would be comparing the quotes and included services to 2 other providers before I make a final decision. I was very impressed with the professionalism and detailed information I received from Mr. Ramirez BUT, he made a LARGE mistake by overlooking the size of my return vent. it needs to be enlarged when going from a 3ton to 4ton system. That's why I am going with another a/c company that says they have much more experience and this oversight by JOTS was all the proof I needed.
