How BTUs and EERs Work

Sizing Heating and Cooling Systems

Words We Didn’t Write Ourselves

Hands down Amazing. We have used Emerald for years. They always show up and are always professional everytime. It started with Alex who came to service our very old machine. Then on his recommendation, which we knew was coming, Justine came out for the estimate. She was personable and extremely knowledgeable. She taught me a few things I didn't know on how to make a machine run well and last longer. She answeredall of our questions. We got our new ac/furnace installed on Friday, 7/30/21. They were on time, professional, answered all of my questions and concerns. The installers, Robert and Doug, were just AWESOME!!!! They made sure to run all the piping neatly and out of the way in our laundry room as it is a very small room. They made sure it looked good as well. Everything was neat and tidied up when they finished as well. It was almost like they were never even here. Robert showed us everything they did when they finished. Before he left, he made sure we were satisfied and he asked us if we had any questions. I would highly recommend Emerald for anything you need. Thanks Emerald 😊
