I LOVE THIS COMPANY, We have had many mishaps with our A/C unit and in the worst time of the San Antonio heat. Got our new split unit from ASC back in the summer of 2017, Oscar was our sales rep, he truly delivered an excellent outcome for us. He was knowledgeable on what was being done every step of the way. I had to be at work the day of the installation and my husband was there if anything was needed but I wanted to see what was happening every step of the way, so Oscar would send pic messages and tell me what was happening, what company would actually do that but Oscar did. CPS was working in our area and the lights kept shutting off and on about 2 weeks ago, weather was warming up and decided to turn on our ac to give the heat a rest and nothing happened, put a request in to ASC and Jason came out very early and he stated our compressor was blown and explained what happens when the electricity flickers on and off and the effects it has on AC units. He put the request in to my warranty company. He was amazing, quick, efficient and very knowledgeable. He came back the next day, got my new unit put in about 2 hours. I recommend this company to everybody. They have been there for us in the time of craziness. Patient and honest. They are my go to guys!!! read more

On July 5, 2023, I cold called ASC and explained what services I thought I needed. I was very surprised that after talking to Adrian on the phone about what my concerns were, I was able to get a technician out to my place within one and a half hours! (I live in an apartment complex. Most HVAC companies in San Antonio, TX do not service clients who live in apartment complexes) The technician, Roane Ewing, was professional, courteous and answered all my questions with patience. He educated me and explained in detail why I was having the problems I told him about. He went above and beyond, took pictures and explained to me what was going on. As it turned out, I was really alarmed about things with my system because of my lack of knowledge of HVAC. He even discovered some problems that he was able to solve on the spot. That will save money down the road for me. Many thanks to ASC for coming out on short notice and doing a great job. I will definitely call them for my future HVAC needs. Keep up the good work! read more

After my home AC went out and I called around San Antonio for 2 days straight in the heat, I eventually got ahold of a particular company and ended up having a bad experience with them as they were trying to convince me to by a brand new Home AC (because of the age- without a thorough assessment) thru their third-party Finance Company. I pulled out of the deal at the last second as I saw online where ASC Heating & Air had some really good reviews. I called ASC and the gentlemen who answered the phone was very friendly, honest, professional and dispatched his tech ASAP. The tech- (Mr. Kman) arrived within a hours time on a Sunday which was Great! He was well-trained, polite, professional, knowledgeable, who was on top of his A- game. He immediately diagnosed the problem and got the repair complete in about an hour's time. The guy was absolutely awesome! I highly recommend this company as they are reliable, friendly, fast, knowledgeable, and professional. ASC, please keep up the GREAT WORK! read more

Initially contacted a few of the larger HVAC and got quotes that were 30%+ above the initial quote from ASC. Since ASC isn't a "Certified dealer" they don't feel the need to keep you tied to a particular brand, so instead of trying to sell an oversized unit, they got the right size (not all companies offer sizes in half ton increments) and oversized is actually bad.https://www.energyvanguard.com/blog/55157/Why-an-Oversized-Air-Conditioner-Is-a-Bad-Idea They were able to come within a few days of contact and were very friendly and efficient. My new system is working wonderfully and when I do some more work I will be looking at ASC as my first contact for any additional quotes. read more

Our air conditioner went out like normal, late at night when everyone is closed, called a few places early in the morning trying to get a tech out to fix the air conditioner. Companies were busy and said it would be late in the afternoon to get a tech out to our home. ASC called me back right away and said they would have a tech out within 2 hours. Jason showed up and did everything possible to troubleshoot the A/C. The A/C was fixed and working great, this is a good company and recommend them for there customer service and service! read more

I would like to thank J.R, at ASC Heating & Air, for his exceptional customer service. Unlike any other HVAC service technician, that I've contacted in the past, he was very courteous and informative, attempting to ensure that I understood the different repair and/or service options available. I called him for a quote and he was there in less than 2 hours. I look forward to viewing his quote(s) for potential repair and replacement ! *I must add that this is the BEST experience I've had with anyone coming to service my home ! * read more

Our Fan Motor and Condenser went out on our Central Heat And Air Unit JR Perez came out today and he was so honest. I never felt Like I had someone I could trust with an issue like this one. Usually someone else would have wrote a really expensive estimate that I knew I couldn't afford. JR Perez walked me through each process to see what was wrong with the unit and did not try to add anything extra to the unit to say this is wrong and that is wrong. Thank God for good people like this. That JR read more

I called ASC Heating & Air for a second opinion. And they accommodated my schedule very easily! Kman arrived on time, was professional, respectful and knowledgeable!! He did not try and sell me a replacement unit, since my unit is from 2013. Communication was outstanding. He confirmed the problem and made some suggestions. In the end, was happy to pay the bill, because it did not break the bank. I now have a new AC/Heating company! The value was incredible. Will definitely recommend this company. read more

The technician came and name is Craig. He does awesome job and "know" what he's doing for this job done..also he is very reliable and very patient guy. He's not the kind of guy working too fast to check around my unit havoc and make sure my unit and etc everhing is okay. Even tho he know little American Sign Language. Hes a big kudos! I highly recommend ASC !! read more

Ron with ASC and his crew were great. They were on time and kept their price as quoted. Ron was honest and explained everything. He did not try to sell me something I didn't need. Two other big companies did. And Ron offered the best price of the two other quotes I got. I will refer them to my friends and will use them again. Thanks Ron read more

Excellent service! Jason, Chris and Jesus were great. They took their time installing my much needed upgraded system. Ron came by and helped me fill out the warranty and CPS rebate forms. They are professional and knowledgeable. I would highly recommend this company. They are truly a 24/7 crew. Thank you for your service. read more
