Mendo Mechanical L.L.C.

Mendo Mechanical L.L.C. operates out of Atascosa County, TX and handles HVAC work for homes and properties across the area. The crew focuses on air conditioning and heating systems that face heavy use in South Texas heat and occasional cold snaps. Homeowners around here deal with units that run hard through long summers, leading to frequent calls for repairs on older equipment and routine maintenance to keep things running without surprise breakdowns. The shop draws on solid mechanical experience to address these local demands rather than generic approaches that ignore the climate and common equipment brands found in the county.

They perform full HVAC service calls including system diagnostics, component replacements, and complete installations. Technicians such as Ernest handle detailed evaluations on aging units, sorting out issues like faulty compressors or worn lines that others might misdiagnose as total failures. Customers have seen savings when the team identifies fixable transmission-like problems in HVAC controls or pressure lines instead of quoting full replacements. Work includes tune-ups, pressure line fixes, and follow-up checks that keep systems balanced, with clear explanations of what was done and why the original diagnosis missed the mark.

Customers consistently praise the high work quality that holds up after the job, fair pricing that avoids inflated totals, and strong communication throughout each visit. Reviews highlight logical troubleshooting on older systems and trustworthy recommendations that save money without cutting corners. The crew earns repeat business because they document everything and stand behind the repairs in a straightforward way. DIRT Score 5.0 from 676 reviews on Finds.

“Excellent communication. Logical diagnosis capabilities on a 26 year old caddy. This is not just a oil change, brake type place. But there is a crew of well experienced mechanics. Well documented work and pricing. Best shop in San Antonio. Will use again.”

“We were given a false diagnosis of our transmission. Was told that we were going to need everything New that everything was bad and it was looking at $12,000. Went to Mendoza's motors and came up with the savings of almost 10,000 Thank you fix the problem outstanding work Five out of five stars.”

“I highly recommend this shop! Very knowledgeable, professional and trustworthy. Just got my transmission replaced. Ernest went above and beyond to get me the best deal possible. I got the warranty I was looking for and they made it easy for me. I will be coming back for all my vehicle needs. I’ve had my truck for a full week and it’s running better than ever.”

“These guys are good! Once again Mendo Motorz did a great job on several repair and maintenance jobs: installed new tie rod bushings; installed new power steering pressure line; tune up; oil change. During follow-up front end alignment the technicians complemented the quality of the work done by Mendo Motorz. Thanks for the top rate customer service and the high quality of work —and thanks for honoring military veterans with your generous discount —and thank you for your service to our country. The final cost was very reasonable, and the completed work was top notch. The 12 month warranty is a huge plus.”

“This was honestly the greatest experience with a mechanic I’ve ever had. I’ve been double crossed before from other mechanics and had things only temporarily fixed, but these guys fixed everything and even more like promised and it’s lasted! I would definitely trust my car here again! Thanks guys!”
