Onofreo's maintenance man immediately did everything necessary to stop the leak, as well as found and repaired the problem. Even though they are more expensive than other companies I've had in the past when it comes to things like this, they can't be beat. He was even nice enough to tell me how to remedy the problem so that it won't happen again and willing to come back to work with the contractor for the repair.

From the first phone call, everyone was friendly, helpful, and happy to answer questions. The customer service alone stood out. Even though they were a little more expensive, the professionalism and kindness made it worth it. It's nice to see a company that still knows how to treat people.

I contacted Cobra on a Friday afternoon when my AC died. I reached the owner, who said he would be…read moreby the next morning to assess. He could not come in the morning because of rain. We communicated via text and it was normal--he said he was looking forward to helping and would call me Monday morning. He did not miss an opportunity to comment about how I should have had it serviced over the years, which I acutely felt bad enough about already. Some technical friends tried to help me Saturday afternoon (it had stopped raining early) by replacing the capacitor. I shared that information with him. He said something strange about 'probably' calling Monday. For context: it was in the middle of a brutal heat wave, and I have 2 kids and a dog. I left a msg and texted on Monday and was . . . GHOSTED. No response at all. It would have been (somewhat) professional to just tell me they couldn't help at that point, but to ghost a potential customer was unbelievably unprofessional. My $12K is going to another company.
