    Words cannot express our ongoing frustration with Douglas Mechanical. We invested over $10,000 in a unit, spent thousands more repairing water damage in our game room due to a tied-down damper AFFIXED by technician Eric Harper, and now we're dealing with a frozen unit again. Eric Harper was just here on 3/13/2025 and confirmed that this brand-new unit was in *good* condition--yet it's frozen once more. This has been a year-long ordeal filled with heartache, frustration, a lack of transparency, and a significant financial burden, all while trying to maintain a properly cooled home for our special needs son.

    Eric was the technician that came out, he called 30 mins before his arrival and was very courteous and kind.

    We are extremely satisfied with Generator Super Center. Today's annual maintenance was teriffic!…read more did everything including the clean up of the generator. Air fliter changed, oil and filter changed, air filter changed, spark plugs changed, He was very knowledgeable and informative. We love the security of having a generator! Thanks CJ, it was a pleasure meeting you.

    1-Star Review -- Generator Supercenter…read more My experience with Generator Supercenter has been extremely disappointing, and I would not recommend them based on what I have experienced. Brandon Tillery was nothing but a fast talker throughout the sales process. Unfortunately, the confidence he displayed did not translate into making sure the job was actually done correctly. The installation was not properly completed or verified, and I was left with a brand-new generator that has experienced serious issues almost immediately after installation. For a $14,000 investment, I expected a properly installed, fully operational Generac generator--not a $14,000 paperweight sitting in my yard. What makes this even more frustrating is that I have repeatedly attempted to get the issues resolved, yet Generator Supercenter has failed to provide an adequate resolution. I should not have to fight this hard to get a brand-new system operating properly after spending this kind of money. A company should stand behind its installation and its customers. Unfortunately, that has not been my experience. Until Generator Supercenter takes responsibility and actually resolves these problems, I cannot recommend them to anyone considering a whole-home generator. What's even more concerning is the lack of adherence to proper processes and procedures. Shortcuts were clearly taken, and as a result, I was left without a fully functioning product. Instead of ensuring everything was installed and operating correctly, they hold the usability of the generator hostage by refusing to "activate" it until full payment is made--regardless of whether the system is actually working as intended. This is not how a reputable company should operate. I would strongly caution anyone considering Generator Supercenter to look elsewhere. I do NOT recommend this company.

    This complaint is regarding Generator Power Systems (GPS) and their failure to complete our…read moregenerator installation despite full payment on June 11, 2025. The technician, William Easton, arrived that day but left due to weather, promising to return June 12. He returned but couldn't complete the job and said he'd be back later that day with another technician--he never came. On June 16, he returned and said a part was needed, assuring us it would be "emergency shipped" through their connection with Kohler and that the General Manager would call. That call never happened. A week later, on June 23, I contacted GPS and was told the part had "just been ordered," contradicting earlier claims. I was promised a mid-week update that didn't happen. On June 26, I followed up again and was told the same thing--without any further communication. On June 27, after another failed call, I received four inconsistent emails from Becky Showers, GPS's accountant, with conflicting part order dates (June 17 and June 23) and no clear plan for resolution. On July 3, I was informed the wrong part had been ordered and the installation could not take place. I was told the correct part would be "emergency shipped" again, with no confirmed date. Despite repeated promises, no one from GPS management contacted me until I issued a firm written deadline for a response by June 30. We've experienced a complete lack of follow-through, transparency, and customer care--leaving us without a working generator during Texas storm season. This situation has dragged on for over three weeks since payment, with no resolution and no accountability from GPS.

    GPS does a great job of inspection to the system, know the issues that pop up, and are very…read moreknowledgeable of the equipment.
