Great Service !!
This review isn’t directed at Mark, but at Carrier. My AC broke down for the second time in four years, even though I replaced it with a brand-new unit in 2020. We encountered the same problem again and had to pay $750 for the service. Typically, these units are expected to last 10-15 years.

Thanks for cooling down the house. Please let me know when the back-ordered part comes in. Thank you!
