This was an annual routine check for heating system, which was installed this April. The check was complimentary for a Mainstream member and no issue at all for the newly installed system. What I like is the tech did the job very carefully and I felt being very well taken care of. One thing prevented me of giving 5 star rating was the after service summary. It listed options of about $5,000. That seems to me something not make sense.
