Eydin came to check out my HVAC system that was not working properly. He was very knowledgeable about systems in place and gave helpful tips. He also switched our filters out which was a great help.
Donald was very informative and suggested settings on the remotes that I had never considered. He explained the reasoning behind the settings. Donald was also very friendly and professional.
Very good experience
After calling several places with two no shows, the moment I called Endless Energy, I felt like I was in good hands. Jake had THE BEST customer service skills and really worked with me to help my situation. This something you don't see that often anymore. My central air cranked out during the heatwave, and he was able to get me an emergency appointment since I have a little girl with complex medical needs who is more compromised in these situations. That same stellar service continued the moment Eydin and Pedro walked through my door to assess and fix the problem. They were pleasant and skilled. They took the time to explain each of the issues, showing me videos of before and after. "Exceptional" service from the first call to completion. 5 Stars and High Five to this Team and your company. You are doing something RIGHT.
Very helpful staff on servicing my 8-year old heat pump unit. The whole house heat pump system they installed 2 year’s ago is working well even though that heat wave we just had.
Easy fix , clear communication, kind and efficient
Mark was very informative and easy to communicate with
I discovered that my central AC unit started leaking water in the basement in the afternoon on 6/24/2025, when it was100 degrees outside. Endless Energy answered my phone close to 5 PM and called me back to confirm my appointment just before 5:30 PM. They were courteous, responsive and reliable.

Eydin arrived in about an hour. He was polite, professional and meticulous. Throughout the process, he explained his diagnosis and solutions he would try. After cleaning the main clogged pipe, he carefully examined the other parts of the central air unit to see if they were leaking. He also gave me advice on getting fans to dry the floor.

I appreciate Endless Energy for their quick response and professionalism in both communication and performing the repairs. Thanks to Eydin and the dispatcher who helped me make the appointment (Sorry I forget your name but you are both awesome!)

Heating and Furnace Repair in Sudbury, MA

How Do I Know If I Should Schedule Furnace Repair in Sudbury?

If your furnace needs repair, you’ll most likely notice a difference in operation and overall efficiency. Some other telltale signs of a malfunctioning furnace or heater include a complete lack of heat when the system is running, heavy dust build up on your HVAC system vents, and frequent cycling.

Your thermostat may also give inaccurate readings or struggle to keep up with outside temperatures. While it can be frustrating when your heating system suddenly stops working, the good news is that the team at [company_name] knows exactly what to do to get your system up and running again.

If you notice any of these common heating system issues, call us:
  • Lack of heat/vents blow cold air
  • Furnace won’t start
  • Overly dry indoor air
  • Loud noises coming from vents

Did you know that clogged or dirty air filters can cause a host of heating system issues, including slow operation and poor indoor air quality? While the air filter may seem like a minor component in your heating system, it’s actually essential for efficient operation.

When air filters become overly clogged with dust and debris, your heating system needs to work harder to effectively heat your home. This can lead to dust in your circulating air, frequent cycling and damage to your furnace. Plus, if your furnace has to work extra hard to keep up, your energy costs can increase.
