My first contact was with Gerald M. who advised of the different options I had to get my unit up and running. I opt to have the whole unit replaced since the old unit was 17 years old. The following day Rey and Victor showed up replaced everything and I was back in business. Gerald M. came by the following day to inspect their work and gave them a thumbs up. Afterwards,I had the City Inspector drop by and he did the finally inspection and he advised they had done an excellent job. Over all I had excellent experience with Champion AC, would I recommend them, yes will I use them again, yes and if you are a veteran, you get a discount. All the people I dealt with from the office ladies, the installers and Gerald were very professional.
