Bob Green- Providence College
Just a Wonderful Company that installed a Heat Pump with two Splits.
In addition, Technician Eydin Gomez has been to my home twice recently and has performed exceptional work in making my Oil Burner and Heat Pump perform very well.
I appreciate his hard work and expertise.
Response from the owner:Thank you so much for your kind words, Bob! We’re thrilled to hear you had a wonderful experience with Endless Energy. It's fantastic that you’re enjoying your new heat pump system. Your satisfaction means everything to us! If you ever need assistance, please reach out.

Brad, the account manager, was timely in responding to my many questions and sending quotes to match my requests. Very courteous, professional, organized implementation crew led by Hunter and his helper Shameel and the rest of the crew that came on day 2. This included moving, without complaint, the location of one of the units which made me very happy.

Update: CJ came to provide annual maintenance in April 2026. He was polite and tidy in his work. Also, he was patient with my repeated questions about ice that had built up on the unit over the winter (which turns out is not a problem).
Response from the owner:Ellen, thank you so much for your kind words and for taking the time to share your experience with Endless Energy! We're thrilled to hear that Brad was able to assist you promptly and professionally, and that Hunter, Shameel, and the rest of the crew exceeded your expectations during the installation.

It’s great to know that the team was able to accommodate your request to move the unit and that it brought you satisfaction. Our goal is always to ensure that our customers are happy with both the process and the final results.

If you need anything else in the future or have any more questions, please don’t hesitate to reach out. We’re here to help!

Why AC Energy Efficiency Matters

Upgrading to a high-efficiency air conditioning system does more than keep your home comfortable—it helps you save money and reduce environmental impact. Modern systems use less energy to deliver better cooling, resulting in:

  • Lower monthly utility bills
  • Improved indoor comfort and temperature consistency
  • Reduced carbon footprint

DIY vs. Professional AC Installation

DIY AC Installation
Attempting to install an air conditioning system yourself can lead to costly mistakes. Proper installation requires handling electrical components, refrigerant lines, and system sizing, all of which must meet strict safety and code requirements. Errors can result in poor performance, higher energy costs, voided warranties, or even system damage.

Professional AC Installation
Working with a licensed HVAC professional ensures your system is properly sized, safely installed, and optimized for efficiency. Experienced technicians perform load calculations, ensure correct airflow, and handle all technical components with precision. Professional installation protects your investment, maximizes system lifespan, and gives you confidence your home will stay cool when it matters most.
