I have used Cooper Heating & Cooling, Inc. for different things around my home, and I will not use anyone else. They have worked on our A/C in our house, and they did the plumbing work when we remodeled the basement. Jonathan, in particular, is the only aerospace engineer on hand, and the kid's a genius. He's a great problem solver with good communication skills. All in all, they provide great service, and I'll hopefully be using them later on this year for our water heater.
