Testimonials
“Mr. Casey was very knowledgeable about home performance. We learned that our furnace and air conditioning units were working harder than they needed to. We found out that the gaps in our home were causing us to have high energy bills. By having NISEnergy check our home’s performance, we discovered where the problems were and also what we needed to do to fix the issues. We would absolutely recommend NISEnergy’s services to others. Since we had an audit done, our furnace has turned on less often and it feels warmer in our home. We are looking forward to seeing the difference in our upcoming utility bills.” -Scott and Christina
