Customer Testimonial

Our experience with MDO Mechanical was absolutely incredible. Our tech Julio came out on a Sunday (on call) and within 5 minutes was able to identify the potential issue. This was after we had our home warranty people(from Sears) come and spend over an hour to only say we needed to replace an entire unit. Turned out to just be a part that needed replaced. Within 15 mins the part was replaced, he had serviced the unit, checked out some other things, and explained us a plan we could purchase for piece of mind. This guy is absolutely outstanding. I highly recommend MDO Mechanical to anyone in need. – Liz M.

Customer Testimonial

MDO mechanical was recommended to us by my brother-in-law. We were pleased with our experience purchasing motor previously as well as with the service during PM calls. Today we bought an air conditioner from Julio who was very pleasant and professional. We would definitely recommend MDO! Pedro & Julio installed our new A/C unit as scheduled. They went over everything they did with me and were very pleasant while in and out of the house. Thank you guys! – Orlando S.

Customer Testimonial

A big thank you to MDO Mechanical Air Conditioning and his team for putting air/heat back in our home! They installed 2 Trane XLi 16 seer systems; complete with heating and thermostats for our two story home. Pedro was excellent; working with us to ensure the best quality product at the most competitive pricing. His team was highly professional and Julio even took the time to stop by our home during install to continuously check the progress and answer any of our questions. MDO Mechanical will be highly recommended from my family! – Jarold F.

Customer Testimonial

JC was fantastic! He made my 17-year-old system, which was not working at all when he arrived, run like new for $300. What a relief! I thought I would need a new system. Julio tested the system and everything checked out perfectly. Highly recommended. – Alianet P.

Customer Testimonial

We’ve used them at two different houses for 5 years and they’ve always done us right with service, repair, maintenance and replacement (AC). One time I called another firm to save a few bucks, that was big mistake so we came back to MDO Mechanical. – Edel N.
