We had a great experience replacing our 30-year-old AC unit. Joe and Andres were outstanding from start to finish. They were professional, knowledgeable, and took the time to explain everything throughout the installation process. They were also incredibly friendly, respectful, and made sure all of our questions were answered. Replacing an AC unit is a big investment, and they made the entire experience stress-free. The installation was done efficiently, and they left everything clean when they were finished. We couldn’t be happier with the service and highly recommend this company—especially Joes and Andres. Thank you for a job well done!

Very pleased with the quality and attention to detail. They installed a new 2 ton split unit that I purchased. Completed the installation in one day. I would highly recommend EHR if you are considering an installation of either a unit that you are purchasing and need installation or a complete package installation.
