Highly recommend their professional services to whom is in need.Posted on greg77059Trustindex verifies that the original source of the review is Google. Mondragon Mechanical is the most trustworthy and reliable HVAC company I’ve ever worked with. Guillermo and Kimberly are simply the best! This was my first time using them, after finding them through Trane’s official website, and I am beyond impressed with the entire experience from start to finish. My service technician was Guillermo, and let me just say -- don’t let his young age fool you. He is extremely knowledgeable, professional, and friendly. I’ve dealt with other HVAC companies over the years for my Trane system, but I can honestly say Guillermo is one of the best technicians I’ve ever met. He knows his stuff, explains things clearly, and truly cares about making sure the system is running perfectly. Thanks to him, my AC is now working like a charm! A special shoutout also goes to Kimberly in the office, who was equally wonderful. From the moment I called to schedule a service call, she was kind, helpful, and kept me informed every step of the way. I had asked for a 30-minute heads-up before the technician arrived, and Kimberly followed through perfectly with that, giving me Guillermo’s exact ETA this morning. Right on schedule -- something that’s rare these days! What stands out most about Mondragon Mechanical is their honesty and integrity. They truly put the customer first and can absolutely be trusted. That is a rare quality in today’s world, and it’s exactly why I will be calling them for all of my future HVAC needs. I’m already planning to sign up for their seasonal service package for ongoing tune-ups each year. Thank you, Mondragon Mechanical, and an extra thank-you to Guillermo and Kimberly for turning what could have been a stressful AC problem into such a positive experience.

I purchased a whole new inside and outside unit last year. I’ve recently had issues with it not blowing as cold air as before, i had them come out to check on it and turns out, either they left the coolant low when installing or it has a leak.. mind you think is a whole new unit i paid $8,500. Now they said it’s not their fault and i have to pay an additional $360 to fix? this is ridiculous! Do not purchase here they leave things half done and then try to get more money to get it fixed.Posted on Graciela GuerraTrustindex verifies that the original source of the review is Google.
