OTS has a long list of commercial mechanical engineering projects to its credit – new construction, renovation and retrofit. Our resume includes car dealerships and garages, small as well as big box retail stores, offices, banks, resorts, restaurants and fitness centres. Although not strictly classified as commercial, we have worked on dental and medical offices, clinics and veterinary service buildings. We are able to provide cost effective, efficient HVAC designs which meet the varying, and sometimes specialized, needs of our clients.
