"As an ESI customer I am very pleased with the decision to go with the heat pump system this past year. With prices soaring this decision sure made a difference in my home heating cost this past season. Though the heat pump was a little more expensive to get started I saw a savings in my first year of approximately $1,200. It paid for itself in year one."—Clay Summers
