Hi, I'm Pablo Martinez.
I started El Potro Heat & Cooling because I got tired of watching Baltimore homeowners get handed vague quotes by rotating techs who wouldn't stand behind their own work.
When you call, I answer. When your system gets diagnosed, I do it. When the repair gets made, I'm the one holding the wrench. Every quote is written down. Every install passes code. Every customer gets my personal cell.
