⭐️⭐️⭐️⭐️⭐️ Eydin did an excellent job fixing my central AC unit! He was very friendly, professional, and direct—no wasted time, just straight to the issue. He quickly diagnosed the problem and had everything up and running smoothly in no time. It’s rare to find someone so efficient and easy to work with. Highly recommend his services!

Aaron came today to do our monthly maintenance for our mini split. He did the best job that we have had in a couple of years. You could really tell that he cared about making sure that everything worked and was clean. He cared about our system and making it look good despite its old age and took extra effort to clean the outdoors unit. It is the most clean it has been years due to that extra effort and I know it put a smile on my face to see it looking brighter and cleaner. He carefully explained his plan when he arrived and then proceed to explain each of his steps while he did them, what he was looking for with the tests, and discussed with us potentially future maintenance that we should be doing to get the most out of of the unit. He even showed us the app he was using to monitor so that we could monitor it with him. I personally enjoyed our conversation and was impressed with the level of his effort on our unit. He respected us and our house and made us feel included in what was going on in a way that really stood out from many of the contractors who have worked on this house.

We've used Endless Energy for a few heating system maintenance rounds and updates. Most recently, Mike Heil helped us solve a cold zone problem in an old house. Mike could not have been more thorough, patient or gracious. It was refreshing to work with someone obviously so expert in his field but who acted like he had all day to think through the problem and review every angle with us. He and team made this process far less stressful than other upgrades we've been through.

Response time was very quick. Alex was able to fix my pump and give me ways to avoid future issue. He was knowledgeable and kind. In fact, everyone I spoke to in the office was very pleasant and helpful. I was so impressed that I immediately called his supervisor to leave a compliment, and i've left a review on google!
