    When your AC conks out in July in south Texas, call My new friend Mario Davila. He answers the phone on an early Sunday morning, sets an appointment for 1000-1200 and shows up at 0930 because he knows you are in a state of emergency. You need people like that when your house is at 100 deg F. He's my new AC company and will be replacing my 20 year old unit in the spring. God bless you Mario and thanks for saving my sanity, my disabled son and my three dogs lives from the heat. 11/5/2017 Finally got around having Mario install my new Payne by Carrier 4 ton unit. Mario and Luis worked non stop from about 0830 am to almost 3 pm. Work was high quality and Mario even vacuumed my carpets when done. Everything was left the same way they found it, except now I have a brand new AC system which I'll be running through it's paces in the coming days. Mario filled all the paperwork for the CPS rebate and provided me with copies of all the documentation. He registered the unit with Payne himself. Mario is a pleasure to work with and I hope he never retires because he's my go to HVAC specialist. Thanks again Mario.

    Mario with DavCo told me exactly what was wrong and repaired the minor issue in an hour for $325.

    Who do I call when my heat goes off? Beluga air. They built the system five years ago and when we…read morewoke up yesterday morning it was cold. Called them at 7 am and a tech Dalvin Jimenez came right out. Found the problem right away (took vids and pics). Ordered the part and at 2pm two techs: Jonathan Osorio and Adriana Rodriguez, arrived with the required parts and replaced the blower. All was covered under their great warranty. We were warm and comfortable last night thanks to their hard work. I can't say enough good things about this companies professionalism and skills. If you are looking for a reliable and hardworking HVAC team. This is it.

    WARNING: Do not trust this company - they trap customers to manipulate and overcharge. I was a…read moreloyal customer since 2021 until they pressured me into paying my annual membership upfront this fall (previously paid monthly). When I discovered their deceptive practices and tried to cancel, they refused any refund. This is how they operate: lock you in financially so you can't leave while they control pricing and force continued, unnecessary spending. The pattern I experienced: paid for repairs with verbal promise of credit toward full system replacement, they refused to honor it. Tech declared my system "dead" while I was traveling internationally, pressured a sale, then suddenly "fixed" it by resetting a breaker when I refused. Two weeks later their project manager texted admitting "we never did anything to get your [system] running" - written proof they didn't complete the work. Another tech came for a heater tune-up a month later, asked if my AC still worked and seemed disappointed it did. Tried to upsell me on a membership upgrade for a "free capacitor" while claiming I needed a full system replacement. My AC died the very next day. They quoted 25-70% higher than other licensed contractors for inferior equipment. When another company came to evaluate my system, they found parts had been disconnected and documented it with photos. If you're already a customer, document everything in writing and get out before you're trapped deeper. If you're considering them, choose any other San Antonio HVAC company. I filed chargeback with my credit card company, TDLR and BBB complaints, and am replacing my system elsewhere - saving thousands for better equipment and honest service.

The AC was running fine until they arrived. Shortly after the workman left the AC stopped working. They came back the next day and diagnosed it as a bad compressor. I had my suspicions that they did something that caused the compressor to fail, but there was no way to prove it. I told the workman that the AC was still under warranty, so the compressor would be free and I would be happy to pay them to repair it since they are a certified American Standard dealer. After the workman spoke to his supervisor, he told me that they couldn't fix it because there were no compressors available in the San Antonio area and left in a hurry. I called another certified AS dealer the same day and they came out to look at it. I explained what had happened and they said that everything that Wilks told was not true. They got the compressor from a local HVAC supply store in about a day and charged me for labor to install the new compressor. I think Wilks didn't want to repair it because it was a warranty claim so they wouldn't make as much money. After that episode, I will never let this company close to my HVAC system and I cannot in good faith recommend them to anyone because if they break it then they will not fix it.
