Our AC stopped working in the middle of a heat wave this over the weekend. We reached out to Ecofficient and Dan was able to come out to diagnose and fix the issue within 24 hours. We are grateful for the quick service to get us comfortable again during a hot hot week.Posted on Kevin EllisTrustindex verifies that the original source of the review is Google. We tried calling the big names in the business and couldn't get an appointment for 2 days, or a call back during the great heatwave of '25. It's hot as balls BTW. We called them today (6/23/25) and Dan, from Ecofficent, called us between jobs on the same day. I know, right. Unbelievable. When he was done dealing with all the other jobs he had today, he came to our house and had the problem diagnosed in minutes and had the AC running in less than 20 minutes. He recommended that I be more careful next time, when weedwacking around the unit. Dan, thank you.Posted on Jesse BesonenTrustindex verifies that the original source of the review is Google.
