OEM SOLUTIONS FOR HVAC MANUFACTURERS

Most of the work we do at Temco is behind the scenes development and manufacturing work for large air conditioning companies. But we’ve done work on many projects unrelated to air conditioning such as a custom wind turbine controller, sports testing equipment, a depth sounder for the commercial fishing industry a laser range finder and a floor cleaning machine controller to name a few. If you have a project that you are making already, or want to see what it would cost to have a certain widget made up to your specs, feel free to send your NDA our way and we’ll get the quote started. Our electronics, software and mechanical engineers will make your project a success. Your budget will go further which can make your product better, not just cheaper.
