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 will be notified around the time we'll arrive.

  2. Notify you before we arrive

    Your AC 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 AC tech arrives, they’ll investigate your air conditioning system and do the calculations needed to determine the system size you need for your San Marcos home. Then, you'll get a price quote.

    For additional information on what factors contribute to the overall cost of an AC installation in San Marcos, reference our blog here.

  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't get to you in time, we'll provide temporary air conditioning or put you up in a hotel up to 3 days - on our own dime.

  5. Make sure you're happy

    We don't just dine and dash. After the AC installation, we will call to get your feedback so we can ensure you're 100% satisfied with the work provided.

"They are friendly and customer-oriented"

"We have been a customer of Reliable Air since 2009 and will not use any other company. They are friendly and customer-oriented and will work on an issue until it is resolved to your satisfaction. Their technicians are professional and knowledgeable. Our technician is Toby and he is very thorough and follows through on his work. We did renovations on our home a few years back and requested our contractor to use Reliable Air for any HVAC work."

"Polite and easy to work with"

"Alan F. with Reliable Air just got done with an A/C inspection at my home. He was professional, called before he came, and did a thorough check-up on my system. He answered questions I had, and was polite and easy to work with. He has also done work at my place of business, and his skill and knowledge have helped us keep things cooling and heating as they should. I highly recommend Alan and the rest of the Reliable Air crew."
