3-D Air is owned and managed by Derek Dalmolin. Derek’s family has been located in Manvel since the 1920’s. He has been in the HVAC industry for 15 years, though multiple family members have been stewards of Derek’s HVAC career from the beginning. He has been fortunate to be the 2nd generation in the HVAC industry. Starting at 16 years old helping family members over the summer, Derek worked in construction from laborer all the way to field foreman. At 23, he moved into an office position where he learned estimating and project management. Derek has had great opportunities learning and working with others and is now applying all that he has learned to work for himself.
