Report
I had an old, old, old rooftop A/C. When it needed service, my service guy would warn me about how hard it was going to be to replace. Not for Elmar! Even when they ran into unexpected wiring issues that pushed the job to two days, they worked so hard to get it done for me and I can't thank them enough. I would hire them again and recommend to anyone. They also had no problem navigating Hampden, Baltimore (alleys, street parking, etc).
