had a great experince with total comfort when I scheduled for a tune up. They sent Jose Vargas one of their service technicians to my home and right away I was impressed. He asked if his billboard (service van) was going to be in anyones way instead of just pulling up in my drive way. Before he came in he put on shoe covers, I thought that was awesome especially since I just had new carpet installed. He was very polite and knowledgable. He changed out my filters and explained the importance of filtration. He even washed my outside unit and sprayed some type of wax protectant. He did a great job! I will recommend total comfort to all my family and friends and will request jose for any future services. Thank you so much.
