t had been over 5 years since we had a tune up on our furnace! We were way overdue. Blue Best was easy to schedule with. I love that I got a text when the tech was on the way with a picture and bio, so I knew exactly who was coming into my home. Casey was awesome. She took time to explain everything she was doing and gave great tips and advice to keep my furnace and air conditioner running effectively. I highly recommend Blue Best!
