The dynamical formation of condensates is studied in the framework of Schwinger-Dyson approach. Two types of condensates are considered here: that which is produced by the exchange of the fundamental Higgs doublet    between two mirror quarks and the other which is produced by the exchange of the fundamental Higgs triplet  between two right-handed neutrinos. The conditions for which fermion bilinear condensates can get formed were analytically found. Mirror quark and right-handed neutrino condensates can be determined through solutions of Schwinger-Dyson equations. Vacuum expectation values of the aforementioned fundamental Higgs are related to the condensate scale. In addition, the threshold for the new strong interactions is found with no fine-tuned requirement.
