Davco Services Company

Davco Services Company runs as a family-owned HVAC outfit based right in San Antonio, Texas. They have handled heating and cooling work for homes and businesses across the city and Bexar County since 1986 under Texas license TACLB013999E. The team sticks to practical air conditioning repair, replacement, heating service, and commercial systems while staying available around the clock for emergencies. Local homeowners and business owners turn to them when units fail in the South Texas heat or when a straightforward fix beats a full swap. Their long track record shows they know the common problems that hit older systems in this area.

The crew handles full HVAC repair and installation jobs plus preventive maintenance on residential and commercial equipment. Mario shows up for late Sunday calls when an AC quits on a pregnant homeowner and gets the unit running again inside thirty minutes with a fair price. He has diagnosed issues on the spot, replaced capacitors, added refrigerant, and even installed a mini split after another outfit pushed for total replacement. The same technician has returned over multiple years to keep systems working without pushing new equipment, and crews arrive on short notice during weekends when indoor temperatures climb past eighty-eight degrees. They cover airflow fixes, indoor air quality work, and complete system installs built for local conditions.

Customers keep coming back because the work shows up fast, stays honest, and holds up without surprise costs or delays. Reviews point to quick arrival times even on weekends, clear explanations of what broke and how it got fixed, and prices that match the actual labor and parts needed. Homeowners note the crew works cleanly, finishes on the same day, and avoids recommending replacements when repairs solve the problem. That pattern of reliable service in tough heat has built steady trust over decades. DIRT Score 5.0 from 68 reviews on Finds.

“Our home AC broke down during a very stressful time, and Mario from DAVCO was a huge help. He arrived right on time, quickly diagnosed the problem, and got everything working again. Mario and his crew were professional, knowledgeable, and worked quickly while still doing an excellent job. They were courteous, efficient, and made the entire process much easier than we expected. His pricing was very reasonable, and the quality of their work exceeded our expectations. We truly appreciate Mario and his crew for their hard work and outstanding service. We highly recommend DAVCO to anyone needing AC repair or HVAC services. Thank you so much guys!”

“My AC went out on a late Sunday evening. I have an 8 month pregnant wife and the heat was killing her. I called Mario and he was at my home in 30 minutes. He fixed it quickly and the price was fair. Highly recommended if you need honest AC work.”

“I highly recommend Mario with Davco Service. He has helped us several times over the course of several years. He fixed our home AC unit after a different company told us we had to replace it. This showed me he was an honest person. He has completed other repairs and most recently installed a mini split unit in our garage. He is reasonably priced and is great at his job. He has taken care of my parents and my brothers AC as well.”

“Mario was recommended to me by my daughter who had her a/c previously repaired. Mario came to my house on short notice during the weekend. It was 88 degrees in my house and getting hotter. He immediately assessed the problem and corrected it. He put in a new capacitor and added quite a bit of refrigerant. It solved my problem and my house is once again comfortable. The previous a/c tech (different company) had installed some contraption and Mario informed me that it was only making my compressor work harder and not addressing my problem. Let me just say this, I’m disabled and in a wheelchair. Some businesses take advantage of this. Not Mario. In my estimation, he is an honest man and upfront with you as a customer. He will be my go to guy for all my future a/c needs.”

“Mr. Mario Davila and Davco Service Co. was awesome! He came within the hour when I called on a Saturday. He fixed the furnace issue very quickly and was patient enough to deal with my home warranty procedures for reimbursement, etc. Furthermore, he was willing to come on the day of his birthday. What a guy!”
