I recently purchased a home built in 1944 and have interacted with LOTS of service and repair persons along my remodel journey. FOR Energy leads the pack in customer service and level of attention to detail. While not the cheapest of my 7 bids, FOR Energy was by far the most thorough and comprehensive of all the companies. No pressure or hard sales tactics and actually demonstrated the need for my duct and air sealing in addition to the planned insulation. They even processed my APS rebates for me. Everyone (sales reps, auditor, and installers) showed up on time and I've already recommended them to my new neighbor and a coworker. FOR Energy ensured the ENERGY STAR certification process was smooth from start to finish!
