DESIGN HVAC

DESIGN HVAC is an HVAC contractor in San Antonio, Texas. The family-owned, woman- and minority-owned business has run since 2020. They perform AC repair, heating and furnace repair, ductwork built to Manual D, ductless mini-splits, and commercial rooftop units. Brands they install include Trane, RunTru, Daikin, Goodman, Mitsubishi, and Day&Night by Carrier. Before any replacement they complete a room-by-room Manual J load calculation and hand over the written sizing report. They state no trip charge or diagnostic fee applies and they supply a flat price in writing before any work starts. Hours are Monday through Friday 8 to 5 and Saturday 8 to 1.

Customers call for full central AC replacements on old units, mini-split installs, air handler and condenser swaps, and repairs when systems stop cooling in summer heat. Neudes handled several same-day fixes and installs, often finishing in under an hour when parts were on the truck. Julie tracked orders, answered emails after hours, and kept homeowners updated during cold snaps or parts waits. Reviews note clean job sites, clear explanations of the fix, and options given for cost versus efficiency. One job moved an in-wall unit to the attic to free wall space and improve maintenance access.

They book same-day appointments when possible, answer phones until 8 pm weekdays and 1 pm Saturdays, and reply to emails promptly. Service reaches San Antonio and nearby spots such as Ingram. Multiple accounts describe fair and transparent pricing with no surprise fees at the end. The company states they only charge after the customer approves the written price.

“Neudes and the team at Design HVAC are simply the best! Prompt responses, same day appointments, excellent work, and most importantly, honest feedback.”

“Technician and staff has done an excellent job installing A/C system and answering all of my questions promptly, sometimes after hours via e-mail. I would highly recommend their services.”

“Neudes did a fantastic and quick job installing my new mini split unit! Would highly recommend.”

“Design AC did a good job installing new air handler and condenser. They picked up and cleaned all trash.”

“I’ve gotta say, these guys really knocked it out of the park for me. When they showed up, I was pretty nervous about having strangers in my home—but they instantly put me at ease with their laid-back Texas charm and genuine kindness. My old HVAC unit was older than my grandpa’s boots, and I half-expected a big headache getting it replaced. But nope—in a couple hours, they had everything installed, tested it thoroughly, and even gave me tips on keeping it running smooth through our scorchers.”

“Professional, knowledgeable and courteous. They properly diagnosed the problem and resolved the problem with our HVAC. The other company that looked at my HVAC just wanted to sell me a new unit. Also, Julie at Design HVAC was fantastic. She should be awarded employee of the month. She was on top of the situation we were in with the weather turning cold. She was empathetic and kept me informed as to what was going on by email. She was always courteous when I called. Julie is an asset to Design HVAC and is the type of employee we all want. I highly recommend Design HVAC without reservation.”

“I couldn’t be happier with the complete HVAC replacement that Design AC just did for my home in Ingram, TX! From the very first call to the final cleanup, everything was top-notch. The crew showed up exactly on time (actually a few minutes early), they were polite, professional, and respectful of my house. They took the time to walk me through the new system, answered all my questions (no tech-speak overload), and made sure I understood how everything works before they left. The installation looks clean and professional, and the difference in cooling and quietness compared to my old unit is night-and-day. Pricing was fair and transparent—no surprise fees at the end. If you need a new air-conditioning/heating system in the San Antonio, or the Hill Country area, do yourself a favor and call Design AC. I’m a customer for life and will recommend them to everyone I know. Thank you for making a big, stressful project completely painless!”

“Although I believe their diagnosis is honest, the work itself is not honest and done by cutting corners and then refusing to fix the issues that result from those cut corners. I had another HVAC company confirm that the air handler they installed was not done right and that's why I'm having issues now. There were several things that should have been done that were not done. Plus, they only used the interior parts of the new air handler that was paid by my warranty company and used the shell of the old unit. Leaving the old moldy insulation. Make sure you check their work and have knowledge of how it should be done and that everything you or the warranty company paid for was done at 100%. Don't believe why they claim they didn't do this that or the other and then refuse to take accountability for it.”

“He installed a complete central air condition unit and was very professional, punctual and honest. I would highly recommend Design HVAC .”

“Honest, Professional, Responsive. We are so happy with the SUPERIOR service Design HVAC provided. Our A/C failed in the midst of a brutal Texas summer. Design HVAC was quick, fair and offered us many options to choose from. Our technician was meticulous, neat and explained his work, as well as offering advice for other concerns we had. Julie stayed on top of our order and kept us informed. We are so grateful to have found them and to be cool & comfortable again. Thank you!”

“Great experience with Design HVAC. Technician was very knowledgeable. He took his time explaining the issue and more importantly during these incredibly hot days still managed to return once a part was obtained to complete the job as timely as was possible. Will definitely recommend this company.”

“Replaced a very old a/c unit and updated the installation from a custom in-wall design to a more maintainable installation in the attic, recovering wall space in the change. They provided a number of different options and provided info needed to optimize cost vs efficiency. Design HVAC was very responsive and communicative throughout the process and completed the work on schedule at a fair price.”

“My AC died on Sunday, July 16th. I contacted my home warranty company on Monday morning. They put me in touch with Design HVAC who promptly arrived on Tuesday, July 18th. My technician, Neudes, was courteous, knowledgeable, and very professional. In two hours my home was starting to cool off. Julie, also from Design HVAC, called me several times to make sure my home was cooling and I really appreciated that as my husband and I are both disabled and seniors. I would DEFINITELY recommend this company for your HVAC needs. I don't give many reviews but Design HVAC is worth me taking the time to write one this time. I really am very appreciative that my home warranty company referred them to help me!!”

“Just a little update: Y'all really messed up. Maybe if you would have actually responded to my service call you would have sold a brand new air conditioner. Yes, thats right, I purchased a brand new air conditioner because I was tired of the constant down time. And no I didnt go through the warranty I just purchased the new unit on my own. Update: it's now been 5 calendar days . I called your number and went straight to voice mail. I called up american home shield. They called and it went to voice mail. They emailed you again. You emailed them yesterday and wrote that I had an appointment for yesterday yet you never contacted me and never showed up. I requested another company because obviously you abandoned the job. I was told that they have to talk to you before they can assign another company to fix my a/c. So I'm dependent on a company that doesn't answer their phone, lies in emails that they are going to service my home. Yeah right. So Tomorrow will be 6 days without air conditioning. I will continue calling your business and continue updating your reviews. Are Y'all even open for business? Are Y'all even a legitimate business? I am so desperate that i googled the address ”

“DESIGN HVAC did an amazing job replacing our Central A/C Unit In August, 2023. It was 104 degrees in San Antonio and the Technician didn’t flinch. He disconnected the old Unit and replaced it with a brand new Unit in the terrible heat. The Technician was knowledgeable and professional. We were so happy! One more important thing I should mention, is that the DESIGN HVAC Office Manager, Julie, was extremely efficient and responsive. She was responsible for making sure all the correct equipment was ordered and delivered in a timely manner. Julie was very friendly and empathetic to our situation of no A/C, and went out of her way to help us. Julie deserves 10 stars out of a rating of 1 to 5. I highly recommend DESIGN HVAC; they were great! 🌟🌟🌟🌟🌟🌟🌟🌟🌟🌟”

“Neudes was very knowledgeable and diagnosed the issue within minutes of arriving - on time. In fact, they were able to get me a same-day appt. Incredible, because of this heat I'm sure they are very busy. He made the repair in about 1/2 hr., which I am unbelievably grateful for. No waiting for parts! He had them in his truck. I will always call Design HVAC first!! I HIGHLY recommend them.”

“Edit*** Been a couple years and we had some condensation issues that Neudes quickly addressed (20 minutes or so) and then had him do a tuneup while he was here. 30 minutes later he bent us over and overcharged us by a ridiculous amount. it is my fault for assuming his prices were still fair but he obviously takes advantage of people who use him outside his normal appliance insurance jobs. ------------------------------------------------------------------------------------------- Moved into a new home after doing a complete renovation only to discover that the HVAC system had several issues including poor balancing between floors along with the inside unit being extremely dirty due to construction. Neudes arrived on time and conducted a thorough inspection. He then provided several informed and reasonably priced options to increase reliability and our comfort. Neudes performed the work quickly and everything is both sparkling clean and running like new. I will be keeping Design HVAC on speed dial for any future needs!---”

“I called Design HVAC and they came to my house on time. The technician was very honest, professional, courteous and knowledgeable. He fixed the problem. I couldn’t be happier with his service. I highly recommend this company to everyone.”

“This is the worst HVAC company I ever dealt with, the guy name Neudes had the worst attitude and had no costumer service skills. This guy walked in the house in 10 mins diagnosed my AC unit and charged for a part that didn’t fix the issue. This company refuse to come back and fix the issue even after our paying the service fee. This guy was incompetent and we get what we pay for when your bid is the lowest. We got our AC looked at again by a more reputable company and the issue was resolved. Don’t waste your time. I will be filling a formal complaint.”

“My old AC unit was leaking freon, and was not repairable. I contacted 4 air conditioning repair companies that were local and asked for bids to either replace my whole system, or to give me partial replacement quotes. I heard back from 3 of them, but they only offered a few options. After a little more research, I contacted Design HVAC, and after a thorough inspection, they provided TEN quotes , with various options! I could not have been more impressed by both Neudes and Yuli, working as a team to give me exactly what I was looking for: a high efficiency AC system at a very reasonable price. Both the outside and inside AC system components were installed in one day, and thoroughly checked out for proper operation. Neudes is an excellent technician, and worked diligently to get everything to fit my existing plenum and ductwork, with great workmanship. This is an outstanding company, with the highest integrity I've seen.”
