I called Assured Comfort Heating, Air & Plumbing at the last minute and they were so nice to come out and repair my thermostat right away. I was a little worried about the cost because I'm on a fixed income, they made sure I knew exactly what the cost would be before they did the work. That was a great relief. I went ahead and signed a maintenance contract with them because they were such professional, caring people. I would call them amazing and I look forward to recommending them. Absolutely great customer service.
