We had an emergency with our AC unit before going out of town, Sean was able to come over and resolve the issue super quick! Scheduling was frustrating due to their AI bot call system, but the humans doing the actual work were incredibly helpful. We will definitely be using this service again if an issue comes up, it would be much better without the AI though.
