Testimonials – Service First AC – San Antonio, TX

Service First Mechanical did a “major” upgrade, removing an entire system and rebuilding the entire air intake and plenum. The system was cleaned and at that time, the owner showed me and talked to me about the Guardian Air product, due to the amount of mold that was found in the main duct. The owner explained to me what the mold was from, and that my system was not balanced correctly. After a complete cleaning and rebuild of the duct work, my system was put back in, balanced and the cold air began to flow! I was very happy with the service, and especially happy with quality of service and the genuine care that was shown toward me an my family. Everything that I was told about the system, the Guardian Air was all true. The owner even followed up with me a couple of weeks later. Anytime anyone asks about, or I overhear conversations about the need for Air Conditioning or Heating services, I am quick to recommend Service First. Since my initial issue I have called on them since and gotten the same high quality service. Make no mistake, the new kid on the block has something to prove!


Had a new system installed and we’re very pleased. The technicians were excellent, very careful to protect our carpets and flooring. We would recommend Service First to anyone wanting a new system and quality work……the technicians were really great!


We got home Friday late afternoon and the A/C was out. Service First was the only compnay I called that guareenteed they would come out that night. David got there around 9:30 and was as nice, neat, and helpful as could be. He was patient, figured out our problem and got it fixed.


Service First a great and respectable company, highly recommend it. I recently bought new home and they did a wonderful and extravagant job designining the AC for my house. Thanks Mark for doing such a wonderful job on my new AC. With the weather we have here in San Antonio, AC is a necessity and it is working wonderfully. Service First did not hesitate in having to work late, on weekends or holidays, they always go above and beyond to meet the needs of their customers. I was very impressed that they came out in such a timely manner and that the workers were very knowledgeable in what they were doing. Any questions or concerns my husband and I had, they were there to provide all the answers. Thank you for your service!


I just want to let you know what a great employee you have in David Villegas. After calling different stores and getting poor customer service. Service First came to my rescue and did an outstanding job! I also want to commend Omar and his partner (i forgot his name). Your customer service is superb. Thank you!


I called a dozen different local service companies to check my A/C system at 7:00 in the evening during the heat of the summer of July 2010. The first to answer their phone was Service First. The dispatcher was attentive and professional. He dispersed a technician – David Villegas, who arrived *WHEN THEY SAID HE WOULD ARRIVE !!! *. There were no vague, gray areas of when he would arrive, and none about the diagnosis of my system. I am an HVAC procurement agent by trade and normally, pardon the pun, “phone a friend” for help. I don’t have to do that any longer because Service First exceeds all expectations I had about sourcing service outside my profession and earns my trust and business.
