Customer Testimonials


My Heat Pump Paid for Itself

“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.”

My Energy Bills were Reduced by at Least 50%

“In November 2006 ESI replaced my 30 year old fuel oil furnace and fuel oil water heater with the highest efficiency available natural gas furnace and water heater. The appliances installed were exactly what I had requested and the ESI technicians were right on schedule. The furnace and water heater were installed neatly and orderly. I did not have to clean up the work area after installation because the ESI technicians did this. With the new night efficiency gas furnace and water heater compared to my old fuel oil water heater and fuel oil furnace my energy bills were reduced by at least 50%.
