Our first three weeks in our new condo, we had no hot water as the calefon needed repairs. We called Jose from his ad in GringoPost, and he and his lovely wife (they work as a team) responded promptly and came to check it out. Four or five subsequent visits later, where he had tried a lot of things (didn't charge for coming out again and again), they finally took the calefon apart and washed every single part. The debris collected in it was shocking. The calefon works like new now.
