We hired Brady Mechanical to clean and perform maintenance on our mini split systems. Patrick was very professional, arrived on time, and walked me through every step. Now we have spotless systems! We will use them for all our A/C needs. Thank you Brady Mechanical!

I had an excellent experience with Patrick from Brady Mechanical. He came out over the weekend to diagnose and repair my AC unit, and I couldn’t be happier with the service.Patrick was professional, courteous, and incredibly responsive. Despite it being a weekend, he arrived promptly, quickly diagnosed the issue, gave me an honest and fair assessment, and completed the repair in a very timely manner. It’s not often you find someone who combines technical expertise with such outstanding customer service. I truly appreciated his professionalism, clear communication, and efficiency throughout the entire process. I highly recommend Patrick and Brady Mechanical to anyone looking for reliable, honest, and high-quality HVAC service. Thank you again for a job well done!

Great installation and service from Brady Mechanical. We experienced a water heater failure and decided to upgrade the entire system. They hauled out the old and installed the new! From start to finish it was a great experience. They took extra care to cover our flooring and when it was completed they cleaned up and you didn't know they were there. Our forced hot water system is top notch and we have hot water on demand. You should give them a call. They actually care about what they do!
