"Amer Talla is the best! He knows the industry, he is an expert HVAC person all-around. Actually, he is a general contractor. He diagnosed the problem, provided a detailed solution, and was the consummate professional. He is not just the expert you should call because he is knowledgeable and professional, BUT he is thorough. You can tell he loves what he does and he cares about his customers. He’s the one I will call for future maintenance and anything else HVAC-related. I highly recommend him!"
