Thomas provided extremely polite and friendly service. More importantly, perhaps, he was also extremely knowledgeable. He told me the last person that came had given me erroneous information. He took care of everything I talked with him about. He also told me the condition status on the evaporative cooler which helped me to decide what needs to be done to it and when I will address it. A wonderful experience! I will use James Plumbing & Heating again!
