I highly recommend Davco Service Co. I have been lucky to work with Mario and he is very professional, knowledgeable and very fair with the prices. He goes out of his way to explain in detail what he is doing and always makes sure that the customer is completely satisfied with the job being done. They are an excellent company and always do a great job!

Our A/C went out late one evening. After troubleshooting a while, I decided to call Davco to determine and fix the issue. Mario and team arrived within the hour, fixed the blown fuse, and did some maintenance (clearing the drain) I neglected. They gave me practical advice on maintaining the unit and gave me honest feedback on what to expect from it in the future (it's an older unit). We appreciated the expert level service and the honest appraisal of the situation. Would recommend to my family 10 times out of 10.

Mario and Davco saved us from this brutal Texas heat. I'm a renter and at the mercy of an owner and a property manager. We were without adequate AC for 5 weeks and when they finally gave the approval, Mario came out on a Saturday and replaced our whole system. He worked tirelessly and got us the cool air. Then he called the next day to make sure we were satisfied and that everything was working exactly as it should. I would recommend this company to anyone needing quality HVAC service.

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!

Hey let me just tell you this guy is honest. Known for sometime very friendly a Christian and I’ll say this once again honest. He replaced my box on my air conditioner that’s sets the power and recently I called him out to ask if he would do the drain line. He told me how to do it myself and that he doesn’t like to come out there unless something is broken. He could have made a quick buck but he chose integrity. God bless you Mario

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.

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.

Davco Service Co. company did a great job fixing my sister's house in Northwest Crossing. Their estimate of repairs was reasonable and fair, right in line (and a little bit less) than three other companies. The service experience was second to none. All employees were professional and highly competent, trained and skilled at what they do. In short, I recommend Davco Service Co. at the highest level. You can count on Davco. They will not let you down.
