These folks are amazing, they immediately responded when my A/C went out and were super professional, knowledgeable, and nice. Mark and Alec worked hard to repair my unit in a timely manner, and saved my life in the midst of this heat wave! Highly recommend!!!

Reliable and Efficient AC Repair Service!I am so impressed! We had a malfunctioning ac unit in the hottest of days and Mark and his team came to fix it. They were professional and efficient!What I loved about them the most is that they circled back with me later on in the day to make sure everything was working correctly. I can't think of a business I have worked with recently that had that type of commitment to excellence. People don't do business like that anymore and its refreshing to see. I appreciate it. They made sure I was completely satisfied and I would not hesitate to use them again. They not only fixed them, they washed them!

We had a great experience! After another company came out twice saying nothing was wrong, Mark came and was able to look at our AC unit and get us a new one all within 24 hours. Very professional, quick, and overall great service. Thank you!

When my AC stopped working, GreenergyAir HVAC was able to come the same morning that I called. Mark was very helpful and professional and was able to fix the issue in under an hour, replacing a broken capacitor and conducting additional diagnostics to make sure everything was running optimally. Very much appreciated!
