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!
I got a MassSave inspection. It was great, what was being checked and the suggestions were all all described to me very clearly.
The technicians were early, very professional and knowledgeable. Such happy easy demeanor. Very quick and efficient in their job. Really enjoyed talking to them about any issues I was having and any future problems I may have.
Eyden's service today was great. He was polite, courteous, and knowledgeable. Five stars.
He was really great at explaining everything
Eydin and James did our annual AC maintenance and once again they did a great job. They are always on time, very professional in doing the work as well as very informative and pleasant to work with. We highly recommend to whoever needs this service.

Northborough Air Conditioning Repair You Can Trust

Northborough homes range from older colonials to newer builds, and each comes with unique cooling challenges. Whether you’re dealing with aging ductwork or high humidity levels, our team provides targeted repair solutions based on local conditions.

Why Northborough Homes Require Specialized AC Attention

Northborough’s mix of older homes and newer builds can present unique cooling challenges. Older properties may struggle with airflow or outdated ductwork, while newer homes often require precise system calibration for energy efficiency. Our local experience allows us to tailor repairs based on your home’s layout and cooling demands.

DIY vs. Professional AC Repair

DIY AC Repair
Homeowners can handle simple tasks like replacing air filters or checking thermostat settings. However, most AC issues involve electrical components or refrigerant systems, which require specialized tools and training.

Professional AC Repair
Hiring a professional ensures accurate diagnosis, safe repairs, and long-term performance. Our technicians identify root causes—not just symptoms—helping prevent repeat issues and costly breakdowns.
