"It went great - I needed a whole new system and they installed it all, super quickly, no problem."

"Core Mechanicals' tech Jason came in and inspected our A/C system. We had problems with it freezing up. They checked the pressures and added refrigerant to fix that. They did an inspection of the entire system and found our air handler to be extremely dirty. He removed the handler and brought it outside where he thoroughly cleaned it (it took a couple of hours to do. It had a lot of dirt and hair. It was really gross to see that was where the air that my family and I were breathing in came from!) The system is almost 5 years old and he removed the dirt and hair that had accumulated in it over that period of time. I highly recommend getting that done by them! The air quality in my house is so much better now. My family's allergies have been so much better, especially with the dog in the home. My system works and cools much more efficiently and they showed me how properly install the filters, that is very important for capturing dirt and dust. So worth the cost! Cleaner air and my electric bill was even a little less! Jason was very informative and explained the workings of my system to me, I never really gave it much thought before. I am having them back out to install UV light/ air purification system. I highly recommend them! Very prompt, knowledgeable service, very professional! Jason said he works from Key West all the way to Key Largo, and works on all brands. I believe they are a Lennox dealer and they also do pool heaters. They are my A/C guys from now on!

"h +Seth was great. He installed the receiver (which we needed and purchased from him @ an additional cost) and hooked up our in home audio system which went through our house and outside patio. He encountered a glitch when there was evidently a problem with the wiring. He did some trouble shooting and found it was a crossed wire from the last home owner/builder. He was friendly, polite and professional. He did not try to push additional charges on us, only what we needed and wanted. We give him an A+!

"I had debated installing a new system for months. I shopped around; looked at reviews; and decided to go with Major League Contracting Services! The owner, Laz, came from Miami to my home in West Delray to give me an estimate. He said my current unit was too small, and that after 12 years it was time to replace it. We agreed on a price, and set an installation day. They came up on a Saturday and installed my new "York 3.5 ton unit." The air handler is in my attic so it was a tad tricky. After a couple of hours the unit was installed! The installers were very quick, informative, knowledgeable, and polite. Laz even came up and explained the work and even offered to file my registration with York. If you want to work with a local company that goes above and beyond to provide excellent service as well as a competitive then Major League Contracting is the company to use. Call Laz today at 786-344-1846."

"Computer did the "gotta send info to Microsoft" but when tried to reboot it ran through automatic repair without success. I did all the alternative without any success. He came and picked up the hard drive on Tuesday and returned it on Saturday. Fortunately he was able to "restore" without any data loss. Very happy with outcome."

"They were great. They were on time, quick, and polite. I'm very happy with their service.."
