We have tried several companies since moving to El Paso five years ago.

I highly recommend this company.

Our A/C units are showing their age and have needed multiple repairs in the year that we have been here. Other companies are frequently late, or do not show at all. Sometimes when they do show they send people who have no idea what they are doing. That is not the case with this company. We have had Oscar take care of our A/C twice already, and both times he is on time, efficient, and he educates us on why the unit is giving us trouble. He is absolutely fantastic, and it makes me feel confident to have someone trustworthy who I can call when there is a problem. THIS is the company that we will be going to for our a/c needs.

I had a frustrating experience after multiple visits for an evaporative cooler that was tripping a…read morebreaker. The technician came out more than once, but the problem was never properly diagnosed. What concerns me most is that a visibly improper wiring connection (taped and not professionally installed) was missed during these 2 visits, even though it appears to be a likely cause of the issue. Instead, I was quoted for a broader repair that included replacing additional components such as wiring and a thermostat, without first isolating and confirming the root cause. The process stretched out over time, including a canceled appointment, and ultimately the job was not completed by Kelly Rush. His choice. He didn't charge me, but what a waste of time. While this approach may work for customers who prefer a full replacement of a thermostat plus exterior wiring (without pinpointing the main issue first). It was not a good fit for my situation, where I was looking for a more narrowed step-by-step diagnostic process. He quoted me 425.00 for a thermostat and exterior rewire. I did not get the choice to make sure my thermostat was even faulty. For context, I was open to upgrading the thermostat, but my primary goal was to correct what appeared to be a previous installer's improper wiring on the exterior of a new Mastercool 6410 unit. I would recommend making sure a thorough inspection and clear diagnosis are done upfront before moving forward with repairs. Photos of the wiring condition were also provided after the initial visits, which further highlighted the concern.

My evap cooler finally died during a 100° day, shopped around with many companies from 'converting…read moreto RA' to 'replacing' my perfectly adequate evap cooler. What I liked about Rush Maintenance is that evaps are his specialty. Kelly (owner) immediately gave me an estimate, and soon thereafter quoted me a fair price. I was scheduled for 3rd day 8AM. He arrived promptly, replaced entire system, cleaned-up, & left before noon. My home even got cold that night--loved it! I asked him if my long-time heating unit needed replacement, he checked it, said no & explained why, I appreciate the honesty. No problems, very satisfied. I recommend Rush as he will get my repeat business. A plus: He speaks Spanish.

Customer service, set up an appointment with them last week to get my HVAC service done, today I…read morewas scheduled. I had to call them multiple times then the receptionist hit up the technician, only to tell me that the tech would be another hour and some change to get to my home, this was after I already waited for an hour and a half. Seems like a glorified lemonade stand to me, they obviously don't track the technicians if they did I would have received some notification that my day would be wasted, book with them if you have a spare day or two to wait around. There are plenty other better contractors to hit up, in my opinion so back to the search for a company that respects my time. A little helpful business advice the techs set a timer and when they bust that time they relay that to the office, which in turn triggers a call to scheduled customers that you will be waiting additional hours, and when this happens you say sorry for the inconvenience how about we make it up to you. RESCHEDULING IS NOT A CONSTELLATION PRIZE. How about you knock 10% off of the bill since I lost wages today but nothing so buyer beware.

They made an appointment which they kept, the actual owner came out promptly, assessed my situation and listened to what I wanted to accomplish and proposed a solution. The next week they arrived and installed the mini-split solution they suggested, complete with the electrical adaptation, exactly according to the specifications agreed upon. This was a few months ago, and now that I have a foster dog in a crate in that same garage, it occurred to me that the confidence we have in letting her stay there when we are gone, is because of the quality of the installation and how well everything works. I'm really grateful for the very professional demeanor and quality service that was provided, really enjoy being able do things in that space without overheating, and I highly recommend this company for their professionalism and quality of service, especially if you need someone to make and assessment and present you with solutions for your unique situation.

Our AC system was installed by 4tech during our new build just under four years ago, and we have…read morehad nothing but ongoing issues since day one. Despite being a brand-new home with brand-new units, both systems have repeatedly stopped working--one due to a motor failure, and later the other for the same issue. No repair they have performed has lasted more than six months. In the beginning, these failures were covered, but now we are being billed $200 for yet another repair on equipment that has never functioned reliably for a full year. It is incredibly frustrating to have continuous problems with what should be high-quality, long-lasting systems in a new build. To make matters worse, their customer service has been unprofessional and inconsiderate. Just yesterday, they came at an unagreed-upon time. I even left work early to be home because they said they would return--yet they never showed. There was no communication, no respect for my time, and absolutely no accountability. Overall, they have been unwilling to acknowledge or correct the repeated quality issues with the units they installed. After four years of unreliable AC, repeated breakdowns, and poor customer service, I cannot recommend them.

Although my AC unit was 12 years old, I was always, always happy and satisfied with their service. So when it came time to replace the old unit, I never hesitated in having them do the work. Javier, one of their best techs, with much patience, explained our options and going with a quick repair would have cost a lot more down the road and still would have required a new installation. They quickly assessed the situation and what was needed that day and completely installed the following day. The two installers, Sergio and Yager were incredibly fast, careful, and efficient. They did a beautiful job insulating the duct from the unit to my house, seal-coated everything, and left the work area clean. On top of all their work, they didn't mind the variety of questions we asked. Nope not at all, both gentleman were patient, respectful, and thorough about answering our questions. The owner, Kike (Enrique) was just as professional and courteous throughout the project. Listen, I am not an employee or paid for giving this review. I stand by my experience with 4 Tech A/C Services, they are good people with a wealth of knowledge in the HVAC industry. You can't go wrong with them! I forgot to mention the office staff. The ladies in the office were incredibly nice from Karen, Kike's wife, and I am sorry, I didn't catch the third lady's name. I really appreciated their help and efficiency. Thank you ladies and Forgive me for leaving you out.
