The office was quick about scheduling an appointment after I had talked to Semper Fi at an event. They were communicative throughout the process too. Jason was the tech that came by for a free HVAC tune up. He was efficient and explained what he found afterwards without being too pushy about getting the work done then. 1 of the jobs I will probably do on my own, and he told me what to make sure I look out for. The other job I will not hesitate to reach out to them to have done.

Mr. McCrae and Pao Pao were very experienced and professional. Both took the time to explain everything and and answer all my questions. Not only were they knowledgeable but they both had a great sense of humor. My belief is they went far beyond to get me the best price for what I can afford and succeeded. I would highly recommend both of these gentlemen.
