      What We Offer

      Generator Load Bank Testing

      Diesel Generator Load Testing is a manual process conducted by our qualified technicians. This portable load bank test enables us to assess the overall performance of a diesel generator by loading it with resistive elements. Throughout the test, all systems related to the fuel system, exhaust system, lubrication system, and intake air are to be tested to ensure that they are functioning within their design capabilities. This type of diesel generator load testing is essential for guaranteeing the long-term performance and longevity of your investment.

      Generator Commissioning and Testing

      As a leading provider of residential and commercial generator installation and start-up solutions for the generator backup system industry, we are proud to offer professional generator installation services. With more than two and a half decades of experience in the industry, we guarantee that our backup power systems are installed to the highest standards and meet all the manufacturer’s commissioning approval requirements. Choose Ferezco Power Systems to meet your start-up and testing needs and enjoy your day-to-day life without any interruption.

      Propane Services for Home and Business

      It is essential to be aware of the size of the piping and tank. Unfortunately, seven out of ten generator service calls are due to incorrect load demand calculations and wrong piping and tank installation. This leads to a bunch of performance problems and premature breakdowns, potentially requiring propane generator repair near me. As a Texas Railroad Commission-certified propane company, we not only specialize in generator repair, but we also provide the highest quality propane services, with extensive experience with alternative-fuel engines. We guarantee that our systems are calculated and well-designed for both repair and propane services.

      Generator Consulting Services

      We take great pride in the knowledge and experience we’ve accumulated over the years. As a result, we’ve built up a wealth of generator consulting knowledge that has enabled us to provide our clients with the highest quality of service. Now, we’d like to share this knowledge with you. Whether you’re looking for advice on selecting the right generator, sizing one, or the best maintenance schedule based on location and usage, we’re here to help. We can even accompany an installer through the entire installation process to ensure that your service is up to manufacturer’s standards. Get in touch with us for all your generator consulting needs! We’re committed to providing you with the best service possible.

      Generator Solutions

      We have established strong relationships over the years, which has enabled us to provide exceptional generator solutions. Long product lead times may discourage the need for a backup system, but you can leave the installation to us. We have a nationwide presence and offer a variety of generators for both residential and commercial applications. Additionally, we provide technical support to ensure that you are buying generator solutions with assurance.

      Fernando and Gabriel did an outstanding job installing my Generac 22K generator. The concrete pad they poured with the pre-piped wiring was excellent and resulted in a very clean look. They conducted a thorough test to ensure everything was just right. I am a very satisfied customer and highly recommend them.
