How It works

How we work in 5 easy steps

  1. Schedule your estimate

    Schedule an in-home estimate online or call us at 512–396–8183. We schedule service in 2-hour windows, so you'll know about what time we'll arrive.

  2. Notify you before we arrive

    Your technician will call you when they're 30 minutes away, so you don’t have to wait around all day.

  3. Give you a price

    Once your tech arrives, they’ll do the calculations needed to determine the size and type of ductless system you need. Then, you'll get a price quote.

  4. Install your system

    We can usually get an installer to your home within 2 days to install a new air conditioner. If we can not get to you in time, we'll provide temporary air conditioning or put you up in a hotel for up to 3 days. Once we get to work, it typically takes about a day to install a ductless system.

  5. Make sure you're happy

    After the installation, we call to get your feedback so we can ensure you're 100% satisfied.

"Thank you for being reliable"

"Reliable Air installed the AC unit in my Habitat for Humanity home when it was built. This is a company that has always been quick to provide excellent service, promptly takes my calls, (thanks Cindy) communicates effectively, and typically gives me a short wait time. Toby has been my trusty technician the majority of the time. He is friendly, honest, and professional in every sense of the word. I had a different technician once when Toby was not available. He did a good job as well with good customer service. However, Toby provides customer WOW! Thank you RELIABLE Air for being reliable. "

"We will definitely use Reliable Air in the future!"

"We called to get our AC Unit looked at and after Josh ran his tests, he let us know that it would be best to get a new system. He was very thorough in explaining everything to my grandma and recommended the best product. A couple days later Dusty and Aaron came to replace the entire unit. The two were very nice and respectful and were knowledgeable about their work. We will definitely use Reliable Air in the future!"
