I called Central HVAC Repair Los Angeles about one of the scariest things: black mold in our central air unit. Devid came with a cheery demeanor and all the answers I needed. My concerns for their quality of service were quickly dispelled, despite initially being given a 4-hour window of arrival. He was very professional and gave me well-advised suggestions to address the problem. Inspection and service were completed in under two hours. Because our unit is quite old, Devid also offered to do research into units that we could eventually replace it with when that time comes. Overall great experience with a caring person. Thank you!
