HVAC reviews in Austin, Texas

So far I'm extremely impressed! Service completed within an hour. Reliable tech. I would recommend this tech to my family and friends. Tech left church to come fix my AC. Worth every dollar. God bless and thank you Sergio!

I called and got many quotes from companies in the area. Blue star has the best pricing available! They offered me next day service as well. Being the busy season for A/C malfunction I didnt expect to receive next day service but was pleasantly surprised! Very friendly and professional service techs as well. my family and friends also use blue star and we are all thrilled with the service we recieve.

“LOOK NO FURTHER!”

I could cry. You have to hire them! Emmanuel was clearly raised to be thorough in his work, quick to find the problem/solution, and very respectable and kind! I didn’t expect to get same day service for our tenants, but we did! He arrived hours before his expected ETA, which tells me he knows how to allocate his time. He didn’t over promise or under deliver. There is a reason he’s 5 stars! Oh! And he got the issue fixed same day, A/C working and everything!! I was deeply thankful and so impressed with this gentlemen’s work, I will use him forever and ever! You’ve gained a forever customer today and I will always recommend you. Thank you, again! 👍

Our AC went out and Emmanuel was able to come out and fix it within a day! He was also very knowledgeable and upfront when answering all of my many questions. Highly recommend!

I’ve worked with Emmanuel at Bluestar for almost 10 years, and he does all of the HVAC work on my 40+ rental properties and dozens of flips. He’s very honest about what is needed, and doesn’t immediately try to get you to replace the entire system like other companies. He tries to save you money where he can on materials, etc.

I can’t imagine using anyone else for hvac work, they’re excellent!

Emmanuel and his father were very professional. They worked around my schedule, and were incredibly thorough in assessing the issue with our A/C unit, running multiple tests to be sure they were certain of why the machine was failing. They took the time to make sure we understood why the A/C wasn't working, and what they were going to do to fix it. Every step of the process we felt comfortable that we were being treated fairly, we never felt pressured to make a decision.

I would absolutely recommend Emmanuel and the guys to anyone I know. It's the first time in a long time I've felt 100% good about a big job done at the house.

I had my heat pump system replaced by Blue Star, and they were fantastic. Everything from being responsive to calls/texts, showing up when they said they would (both for quoting & installation), having the lowest price quotes and noticing things other big companies didn't, getting the job done quickly & professionally. Highly recommended.

I rarely write reviews but had to because these guys were so amazing. After power in my area went out on Saturday my ac wouldn’t come back on. I had another company came out Monday- they were nice and diagnosed the large issue but then told me they didn’t have availability to get it repaired for another 10 days. I called around to a variety of places and then a friend recommended Manny. He responded quickly- set up time to come the next day and told me had time the day after to repair if needed. Sure enough less than 48 hours later, I am back up and running. They were kind, communicative, and clearly just wanted to help me get it solved the quickest and most economical way possible. I am so unbelievably grateful to these guys and from now on they will be my first call!

I always use Emerald HVAC for all my jobs as well as recommending them to all my clients. Quality work for an honest price.

Emmanuel and his team are incredible and trustworthy. I would not go to anyone else. No upselling or advertising, just honest work.

They kept my system running for 3 more years (made it to ~17 total) when other A/C guys just wanted to sell me a new one.

When I was ready to replace for a higher efficiency unit, they gave me a much better price than I was previously quoted, so I was able to get the 30ish-year-old air ducts replaced too.

Call up emerald for your a/c issues and you won't regret it!

This whole experience was excellent from the fast response to the quick scheduling and the cost saving repair. Russ did a great job and saved me a bunch of money over what another company was going to charge me.
