 to make sure you're ready for the hot, hot summer ahead. Your AC works hard to keep you and your family cool. While it's built to last for years, in the Arizona heat, the daily wear and tear on your AC takes a toll. A tune-up from Penguin can help extend the life of your AC and keep your cooling system in tip-top condition. And for a limited time, an AC tune-up from Penguin is only $29. Too many homeowners wait until something goes wrong with their AC before calling Penguin. And often, this means you'll pay more for repairs than homeowners who take care of their AC by getting an annual tune-up.
