About Us


Lawrence P. Krodinger, Sr. was a member of the first graduating class of St. Pius X High School in 1963. He then attended Flat River Junior College (MAC) and Northwest Missouri State University. He began his drafting career with Wagner Electric. He then went on to work with Quality Heating from 1967 to 1980. It was in 1980 that he ventured out to start his own union heating and air conditioning business. This humble beginning with just four employees has grown to a sixty employee operation.

SMCI’s family business has always been about high integrity and treating people they way you would want to be treated, like family! When the doors opened in 1980, SMCI was mainly a commercial contractor in every aspect of their operations. When family members requested new home systems or were in need of servicing, SMCI was there for them. This has been our residential story for many years as the commercial and industrial work kept us hoppin’!!! Family requests shortly grew into friend’s requests and has slowly built over time. We treated them like family also!! We have now decided to give the family treatment to everyone!!! We have now opened our doors to the public as HOME by SMCI so everyone can experience the “HOME” treatment.
