What do customers say about our work?
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.
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!
Mark and Alec were very nice and professional. They came in and identified the issue quickly. Fixed us up in less than 40 minutes. They replaced the dual run capacitor. Even followed up the next day to check in on the repair. I recommend this business, they are knowledgeable and easy to work with!!
Mark was great and professional. After three days of no air conditioning we were dying. He quickly identified the problem to get our house cool again. Highly recommended
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!
