I had a remarkable experience with Environmental Heating and Air of NC, Inc. It took one call, asking a lot of questions, getting answers in laymans terms. No pressure, arranged for a home visit for an estimate and all of my questions and concerns were answered and resolved. The pricing was gimmick-free, a fair, low price from the start. No games, no need to sharpen pencils. The experience was beyond belief. Chad was one who you felt completely comfortable with and would not sell you more than you actually needed. A phenomenol experience. My first quote for a lesser system was 60% more money! But the follow up customer service was also appreciated and impressive.
