I have an older hot-water heating system with a boiler. I had cold rads, even though I bled the air from them. The Direct Energy technician came in at the time the dispatcher said he would, and quickly diagnosed the problem as a flooded expansion tank, and fixed it. He answered my many questions about the set-up, and demonstrated insight and competence. He was polite and very personable. All in all, a very favorable experience.
