Service First AC -

AMAZING SERVICE!! I am so happy that I found Service First! Not only did they show up after hours (9pm) w/in 20min of me calling them, they diagnosed & fixed the problem w/in 5min of looking at the unit. It’s cold & I saved a TON of money choosing Service First instead of going with someone who told me another part was broken. Jack gave great service, fast service, and WE ARE ONE HAPPY FAMILY with this Texas HEAT!! I completely recommend Service First and they did a hell of a job. It was HOT in my house. Now we can all relax in the COLD COLD AC! Thank you so much!!

I have an older home and while my inside unit is a bit newer the outside unit is quite old. I returned home to a very HOT & HUMID house last weekend in the early evening. It was miserable! I called Service First and a technician was at my house in no time. He was very courteous, mindful of the time of night and quickly determined what the issue was and set to work fixing the unit. He was able to replace the compressor and get the unit back up and running. This is not the first time I’ve used Service First and it won’t be the last.

Service first is hands down the best air conditioning and heating company in San Antonio. I called two other places and they could neither accomodate me or give me a fair price. Service first came the very next day and got the job done in half the time and were very affordable. They even sent additional trucks to get the job finished in time with no extra charge. Not only did they keep their word but were very knowledgable and professional. They were very friendly and answered all my questions. Thanks Juan and Esteban for all your hard work, you guys rock.

When my a/c stopped working in this heat I was sunk. I contacted Jack at Service First Mechanical and he came to my aid. After an initial diagnosis the problem was grave, but he came up with an innovative solution to help get me on my way. At a minimal cost and a job well done, an hour later my a/c was working better than it was before. I rate this company as a 5 star and will recommend them to others.

David Villegas did a great and thorough job on our AC. We will definitely use service first again. Great employees great prices. You can’t beat that. Thank you again David!

Service First was exceptional, and I would definitely recommend to anyone in the San Antonio area. Very prompt service and David was extremely helpful and polite. He explained any problems and questions we may have had.

I was desperate and Jack from Service First came to my rescue! I had been waiting 5 days for my property management company to fix my AC, they either didn’t show up at all or fiddled with it and said it was fixed when it wasn’t. It was late on a Saturday afternoon, he came quickly at the time he said he would be here and had it up and running in less then a half hour. Thank you, thank you, thank you!

Service First AC -

You call, they answer, they are on time, they repair or replace. Fair pricing, technicians take the time to explain, pleasant and personable, honest. Owner oversees and takes responsibility and ownership of his business. Techs are neat and clean behind themselves. Work until the job is complete and done right! Quality that needs to be shared with other industries……very happy and have saved money by choosing the right system.

Brandon Jonas, the technician for Service First came to my home and serviced both a/c and heating systems. He arrived on time, which was a surprise based on my experience with other companies. Brandon was courteous and professional in his actions and appearance. He took extra care to protect our flooring. He did an excellent job and offered so suggestions for making our unit last longer. I would recommend Service First to anyone. I will be using their service in the future.
