Blue Ribbon is more than just an HVAC company. We’re family. For more than 20 years, we’ve been a community staple that’s provided customers in the Greater Austin area with ultimate comfort. Our skills, quality workmanship, absolute honesty and budget-friendly services are what make our team No. 1 in area comfort.

"Everything was good they came did the work and I am happy with the installers. Had gotten bid from other contractors but wanted someone to do all the work without having to use two different contractors. They fit the bill. I only wish that when the person who gives the quote that they don’t say something that is not true."

"I had a Trane A/C installed by air systems. Carlos and his crew were on time, worked very efficiently and finished the installation within 1 day despite having to widen the attic opening. They cleaned up carefully and were professional in their communication. Also, their price was about $1000 less than the closest competitor. Would definitely hire them again!"

Your trusted advisers for AC repair, furnace repair, plumbing and electric in Austin, Texas. Fox Service Company is a local heating and air conditioning, plumbing and electrical company that has been in existence since 1972. As a family oriented company, we employ local team members committed to providing the highest quality service. We service the greater Austin, TX, Metro area, including all of Georgetown, San Marcos and Round Rock, Texas.

"PAID $14,000 for an Lennox system ONLY 2 YEARS AGO. Fox installed and serviced it. Recently, system stopped working and a Fox tech charged us $320 to fix. It stopped working 3 days later, so they came out again. Then, they wanted $3244 to replace the coil. NEVER buy Lennox (look up the class action lawsuit RE coils). NEVER use Fox (I've been pushed up to a "supervisor" 4 times with no resolution, the last one has yet to call). Lennox system's have faulty coils (see Reddit). Fox says they NOW don't use Lennox. (Head scratch) You make the connection. So, all I asked for was a new coil installed (part covered under warranty, 7 yrs left) and a guarantee that if it failed again (meaning I'd pay this time and have seven TX summers to go), Fox would not charge me for labor ($3244...pretty steep price too)...no call back."

"I really needed my outside faucet replaced, it was not working properly and was very hard to turn off, to prevent leaking. I called Excalibur Plumbing and they sent Curtis out to fix my issue. He was very friendly, courteous and easy to work with. I use this faucet a lot in the summer time to water my flower bed and my yard. It's now working better than ever! Thanks Curtis!"
