100+ degree week in Escondido and my AC stopped working. Konstantine came out promptly, quickly diagnosed the problem, and made the necessary repair same day. He stayed to make sure everything was working correctly again. I would definitely use him again and recommend to friends!

We’re still in the middle of working with Casey, but I wanted to leave a review now because our experience so far has been fantastic. Casey, the owner, has been helping us replace an AC unit that unexpectedly went out and has been extremely helpful, responsive, and communicative throughout the entire process.
We’re also in the middle of a home remodel and just uncovered some HVAC lines that need to be rerouted. Casey has already been incredibly helpful in talking us through our options for that as well. I’ve felt very comfortable with his recommendations and the service we’ve received, and everything has felt very fair and transparent.
I’ll be sure to update my review once all of the work is complete, but based on our experience so far, I would absolutely recommend Casey and his team
My Ac was blowing warm air, reached out to KC and he responded within minutes. Even had time to fit me in today. Not only that he was able to find the issue & fix it. I am truly grateful. I will definitely recommend to friends & family. Thank you again.
Mere words cannot begin to convey my satisfaction with the work and service that Casey provided. He was everything you would expect from a professional; communicative, knowledgeable, and thorough. I must also add that this has been one of the greatest examples of customer service I’ve had the privilege of experiencing in decades. Casey and the company he works for has earned my business for life and I will recommend him to anyone that is in need of his services. A job well done and I am appreciative for his efforts on my behalf.
Very knowledgeable with fast professional service. Highly recommend.
The team came to install the AC system and did a brilliant job. They were very nice and super helpful. I will definitely recommend them!
High quality and very friendly team!
Exceptional customer service from my initial phone call to appointment scheduling, communication about the appointment ETA with a great map and timeline sent via text, the A/C repair, explaining the work involved in layman's terms, and payment process. I highly recommend working with Airist.
100% recommend Airist!
My AC failed during a brutal San Diego heatwave and every other company I called was booked out for weeks.
Thankfully, Airist fit me in and saved the day! Casey arrived exactly on time, quickly diagnosed the issue and explained the solution clearly. He was very professional, fully equipped, and worked tirelessly to restore my cool (pun intended!)
I couldn't be more pleased with their exceptional service and recommend them without hesitation!
Great friendly service! Will definitely be using them again in the future. Thank you!
