I had my first yearly maintenance done after installing heat pumps last year. I am not a "review writer", but I had to write this review because I was so impressed by the technician, Eydin, who did the maintenance. Very pleasant, very knowledgeable, and was able to do everything quickly and efficiently, explaining things along the way. I learned so much!

Gabriel came out to do our annual maintenance today, and I wanted to pass back compliments on his professionalism and kindness. He did a great job explaining everything to me and provided top-notch customer service. He said he recently joined the company, so I just want you to know he is a GREAT hire! Thanks, Gabriel!

Eydin came last week to service my heat pumps. He clearly explained everything that needed to happen and showed me what I could do to ensure optimal performance. I am extremely happy with his professionalism and kindness.

Gavin was here to do our mini split cleaning. He was exceptionally professional, thorough, and careful in his work. We also discussed other home heating issues (e.g., boiler maintenance). He was knowledgeable and clear in his explanations. We can’t recommend Gavin and Endless Energy highly enough since we are very satisfied customers!

Exceptional Service from Eydin from Endless Energy on our annual maintenance check on our Fujitsu heat pumps. I can't say enough good things about the experience. Eydin was outstanding from start to finish. He arrived right on time, was incredibly professional, and clearly knew his stuff.

Special thanks to Don and Cameron for their thorough annual maintenance on our LG heat pump. Above and beyond the call, ensuring condensation water drained properly - completely ready for the summer. Many thanks.

Common Furnace Issues We Fix
We’re committed to providing the best possible service. Our experienced technicians can troubleshoot and resolve the following issues:
No Heat or Insufficient Heat: We get your furnace working again if it’s not producing heat or the air isn’t warm enough. 
Strange Noises: Rattling, banging, or squealing noises are strong indicators of a problem.
Faulty Thermostat: If the thermostat is the source of your heating issue, we can repair or replace it.
Frequent Cycling: If your furnace is turning on and off more often, it should be checked out by a professional.
Benefits of Regular Heating Maintenance
Maintenance has many proven benefits. Our technicians check for common issues and can determine why you’re not getting consistent heating. They can see why your energy bills are high or your furnace is making noise. 
Routine service has the following benefits: 
Improved Efficiency: A tune-up helps your furnace run more smoothly, so it consumes less energy, which can lower your utility bills.
Increased Lifespan: We can help prevent major issues that can shorten the life of your heating system. 
Fewer Safety Concerns: Carbon monoxide, gas leaks, fires, and no heat are unlikely if your furnace is well-maintained. 
Better Air Quality: Replacing filters and clearing any soot or dust helps ensure you have cleaner air to breathe.
