Our a/c unit went out during the weekend. I contacted my home warranty, and they contacted Zen Aire. Zen Aire followed up with me immediately to ask what was wrong and then provided me with a service time and date. They followed up the phone call with a text message, and then called the following day to confirm the date again. Originally, they were going to come on Tuesday but were able to come 1 day earlier. Eric and David arrived on time, immediately found the issue, fixed it, and also helped fix a small rattle I was having with my second a/c unit. Very professional, fast service, and nice guys. And for those who are interested, yes, they showed up wearing masks. I would happily use them again!
