We had our spring AC maintenance visit yesterday. David Beam was here – we always request him. He is great! He’s very friendly and thorough. He clearly explains what he has done, and any concerns or problems that he may have found. He is a superb representative for Energy Services....

They are always on time. Very knowledgeable. They called to reschedule my A/C maintenance because they had a cancellation and could come a month earlier than my scheduled appointment. I appreciate that they are always looking out for their customers.

Susan was very detailed and did a fantastic job cleaning and inspecting my air conditioner and furnace. I had a problem with my Nest thermostat and Susan also fixed that. Needless to say I am extremely pleased with the service provided.

Brandon and Andrew showed up on time and proceeded to explain the works that they were about to do. They were courteous, knowledgeable and able to answer all my questions. They worked efficiently and the results were really good. I’d recommend them and Energy Services for AC and Heating needs.

Always great service! I’ve used them for years and recently had an equipment issue. They went above and beyond to work with the manufacturer to identify the issue and get me an upgraded product covered by warranty.
