We had our AC fail during a sweltering summer, so we called Sky Heating & Air Conditioning for help. They sent someone out the same day and got the job done efficiently. The technician was friendly and took his time to explain what was wrong and how he fixed it. I'm pleased with their service and have reliable cooling again; I won't hesitate to use them again in the future.

We paid for an annual membership that was supposed to waive service fees for a year, but the company doesn't even exist at the address listed in their ads. The tech wasn't sent on time and when we called for an update, they said they'd need to reschedule. We were left without heat and hot water for over 24 hours because of this. Their lack of follow-through is appalling. The whole experience feels like a scam - very shady business practices.
