"A Hight on Homes were amazing to work with. We've now used them 5 times over the last 5 years and each time they were quick, professional, and saved us thousands of dollars over competitors. We started with a free home energy audit they were offering. They then helped us apply for government rebates to get our entire home weatherized which cut our utility bills in half! They helped inspect our roof after a hail storm, which only needed minor repairs. They helped us when our heat pump was on the fritz and offered a substantial rebate on a replacement heat pump. And then just this month we called them again when our water heater went out so that they could help us get that replaced and again, apply for a rebate for getting an energy-star rated appliance. Bobby and his team know this business so well and are some of the kindest people we have ever met. Get your home energy audit from them so that when you have an appliance go down they will be ready to help you apply for energy rebates much more quickly."
