HVAC reviews in Atlanta, Georgia

Hired to replace water heater and connected to tank water heater already installed and said added tankless water heater. Collected money via
cash app. Do Not use!!!!

After 4 visits I still don't have a heater that works. For almost every visit he wouldn't show until after 9pm to do any work and then would leave in a hurry. In addition to not fixing the heater, he left the unit running without a filter, left the unit so that the only way to turn it off was at the breaker, and tracked mud through the apartment. After scheduling yet again to get it fixed he missed the 12-2pm window and then said he'd be between 9-10pm. Then, after saying he was on the way at 10:40pm, he never showed and stopped responding. He's a nice guy but not reliable or thorough.

I would give this 0 stars if I could.

I was out of town and a tenant called to let me know that the hvac wasn't working. So I called the only 24 hour line I could find in my area. THIS WAS A MISTAKE! They said that they could be out by 9 that night. the tenant was home and did not receive a call until 10:30 to let them know that they were 30 min out. They never showed up to fix the hvac. I call the next day and they have us scheduled between 2 and 4, but did this without notifying us at all. We had to reschedule for the next morning as we could not make this time work.

They leave an invoice with the tenant but it has no itemized cost. It only included the part that was replaced but no labor time and no item cost. They start calling my roommate for payment instead of me after I explicitly told them who to call and what to call them for. Now they want me to pay 400 for a $12 part and an hour of labor. I realize that this was a short notice call and that could include markup for part and labor. I'm totally fine with that as it's 95 degrees outside and I have pets that need air conditioning. They did not give me an estimate and expected me to pay with out having seen an invoice.

This is all on top of terrible services. They are very difficult to get on the phone and do not communicate changes in planned times. They constantly interrupt me on the phone. I told them that I just wanted to see an invoice before payment but I was told that they performed a service and expected payment and then they threatened to come and remove the part.

Overall this was a terrible experience. DO NOT CALL HERE.

Joey has been out to our home several times when we have had issues arise and has promptly resolved our problems. We have an old 1920s home with major appliances that are "at life expectancy" according to our inspection. We have expressed to Joey that we need to try everything we can to make them run as long as possible due to the costs of replacement. He has gotten our A/C working after being broken in the dead of summer 3 times now. We tried to install a new thermostat and didn't understand how to rewire the new one. He came quickly and got us back up and running.

We had similar poor experiences as the other reviewers. Joey did not finish the job and never gave us the warranty paperwork. When we called him about this he and his assistant gave us the runaround- He never showed up when he said he would and now we can't get ahold of him at all. The voice mailbox is full. We will be filing a complaint and I will continue to warn consumers about his shoddy work. I will update my reviews if Joey makes it right. Save yourself a big headache and find a legit and honest HVAC repairman. You get what you pay for. I learned my lesson!
