• 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.

  Chrissi F.★★★★★

• 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

• I Have Used Davco Over The Years, & They Have Provided The Best Service I’ve Ever Encountered From Any HVAC Company I’ve Done Business With!

  Frame M.★★★★★

• 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.

  Mark S.★★★★★

• 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.

  James S.★★★★★

  Jorge A.★★★★★

• 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.

  Thomas L.★★★★★

• 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!

  Jose G.★★★★★

• 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.

  Sandra T.★★★★★

• Mario and company deliver! They show up on time. They give a correct diagnosis and a fair price on day one. Davco Service Co is our dependable go-to!

  Andrew C.★★★★★

• Excellent service! Quality and professionalism. 100% recommended.

  Sam T.★★★★★

• My AC went out late at night. Mario came over at near 10:00pm and diagnosed the issue and fixed it. He also checked out a few other issues with the unit that might need to be addressed in the future. I highly recommend Davco for your preventative and repair AC services.

  Joshua P.★★★★★

• I had an issue with my AC fan not turning on, and unlike the big named companies which could not see until the next day, Mario was able to come see me and FIX the issue with 2 hours! Thank you so much Mario! You have a repeat customer, until you retire ;) Loved talking to you and thanks for fixing my AC!

  Henry V.★★★★★

• Great response time and very professional work! Fairly priced and great knowledge. Will be our primary hvac company going forward!

  Chase S.★★★★★

• I recently had issues with my heating system. I called Davco, and Mario had my system up and running very quickly. He was very professional, prompt, and had a huge wealth of knowledge! I have used a lot of other Hvac companies in the past, and I will say Davco and Mario have been by far the very best!

  Luis M.★★★★★

• Mario has serviced our unit for years, and once when we are having any hvac problem, I know he’ll take care of us. While he works on our issue he explains what’s going on and really tries to find the problem instead of recommending a new unit. He has saved us many times and we will never look for a different company. He’s truly a blessing when you need an HVAC technician.

  Roberto G.★★★★★

• Mario is one of the best technicians a person can ask for, our AC went out at 5am on a Saturday morning and without hesitation he was at our door helping us out! He was quick with his diagnostic and went straight to work! Prices were reasonable as well! Inexpensive and quick! Thank you again Mario!

  Kim★★★★★

• We had a problem with our A/C in a newly purchased home. We called Davco because they were closely located to our home. Mario was responsive and was available that day, whis is great especially in the hot of Texas summer. He came over and diagnosed the problem right away and luckily it was an easy fix. He was professional, polite and thorough. 10/10 recommend!
