Saving You Money on Your Energy Bills

Many other HVAC companies neglect how important your ductwork is in relation to your project. Not all ducts are designed equally, and the wrong ductwork layout will cost you. Your ducts manage the airflow in your home.  If your ducts cannot handle the air your system produces, it will cause the unit to be less efficient and you will not feel comfortable in your home. You’re essentially wasting money on comfort you’re not getting.

This is why we properly size your A/C or furnace unit. If either of these are too large, it will be too much for your ductwork to handle. If your A/C or furnace is too small, not enough air will pass through. In both cases, the result is the same. Poor air flow = uncomfortable homes.


We make Collinsville homes comfortable!

Making your home energy efficient and comfortable with the right equipment doesn’t cost as much as you may think. We have financing available, and our comfort experts make sure you get every available rebate and incentive to help cover the costs.

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
