Nick VerhamTrustindex verifies that the original source of the review is Google. We have had an extremely poor experience with Automatic Climate. We had a maintenance service agreement plan with them. Our tech who performed the annual maintenance was great and professional, but the other techs and office staff were very frustrating to work with. Our HVAC stopped blowing cold air one week after our maintenance service. When the tech came out, I asked if it could be the blower motor and he said no. He then misdiagnosed the issue as a refrigerant leak and charged us $1500 for refrigerant and a leak test, which did not fix the issue. He also tried to upsell us on duct cleaning, even though our service one week prior had not indicated we had dirty ducts. Since he did not fix the system, we were without HVAC for an additional day and a half until a different tech would be available. The different tech was able to correctly diagnose and fix the issue, which was in fact the blower motor. I tried to call the office to discuss the billing for the work. I called 5 different times, each time having to explain my issue, and was told that someone would call me immediately. No one ever called me back and this went on for over a week and a half. Finally, I called and someone was able to explain the billing. They ended up charging us for the work that was required to fix the issue with no discount for the misdiagnosis, additional days without HVAC, or the MANY issues trying to get in contact with the office. The misdiagnosis was frustrating and mistakes happen, but the office is disorganized and poor at communicating with their customers especially when dealing with an issue. I would not recommend using Automatic Climate for HVAC services. Scot WirthlinTrustindex verifies that the original source of the review is Google. On time, efficient, polite, thorough

Thank you for your feedback! We're glad to hear that our team was on time, efficient, and polite during your service. Eric BarnumTrustindex verifies that the original source of the review is Google. I have worked with several HVAC co since moving to Midlo in ‘11. Automatic Climate quickly became our servicer. They have been fantastic. At the end of June ‘23, one of 2 outside air handlers began acting odd so we scheduled an appt. I was expecting the usual crew but was surprised when a lone professional came one, Antonio. I want to note several things. I always have questions. While working, Antonio was pleasant and professional and got the work done and answered all my questions. He also uptalked the company to the point I was thinking, “Should I apply for a job here? Wow!” Besides fixing what turned out to be nothing, he found a warranty issue that would have been so easy to hide the weekend before the 4th of July. He got it done. Through it all, on a 98 deg day, Antonio painstakingly went through everything when it would have been so easy to not. I wouldn’t have known. The ethic demonstrated is a credit to the company. I want to note both the excellent service and professionals, like Antonio, who work here. Thank you. Timothy FergusonTrustindex verifies that the original source of the review is Google.

DIY Steps to Fix Leaking HVAC Air Conditioner
Ready to fix leaking HVAC air conditioner issues yourself? Grab a wet-dry vac and some elbow grease—here’s how:
- Turn off the power—no one likes a shock with their fix.

- Check the filter—if it’s dirtier than a mud pie, swap it out to avoid frozen evaporator coils.
- Inspect the pan—cracked? Seal it temporarily with waterproof tape.
