Our ac unit went out yesterday and I called them today at 11am they scheduled an appointment for Hunter to come out at 1. He showed up right on time and explained all our options for a new one. He was very honest and a knowledgeable on the different types of units and how they would do the job. I signed a contract for them to replace our old unit. I would definitely recommend this company for your needs. Thank you so much for coming in the same day and more

These guys are fantastic at what they do. From the get go I recieved a free estimate for work on my home to make my attic space livable. Within a week they had an excellent service team at my home replacing duct work and improving the insulation in my home. Everyone on their team is friendly, courteous, and knowledgeable. I highly recommend the Energy Stars team to anyone looking for a great deal done by professionals!read more

Have been using Energy Stars for maintenance for the last couple of years after the purchase of my new heating and cooling system. I have always been happy with the service I have received. Today I had a different tech than usually comes out. His name was Dave and I have to say he was the most professional and most thorough service provider I have ever experienced. Thanks Dave, I appreciate the work you did at my house today and the excellent service you more
