This was the WORST trade we dealt with during our custom home build. The owner doesn't know anything about modern systems for HVAC. , his limitted knowledge lead to many obstacles and delays during the process., not to mention the money wasted on drawing revisions, purchasing the wrong vents and installing them incorrectly due to this companies lack of knowledge. The people that work for him are competent but the owner himself lacks the knowledge required for his trade. I'm not one to write a bad review but I do not want to see others go through what we did with this company . Use somebody else, anybody else.
