They loaded an incorrect unit on the truck that the technician/installer recognized after the demo of the existing unit and instead of ignoring and installing anyway (sometimes challenging for a homeowner to know the difference) he called the company and went back to pick up the right one and was still able to complete the installation within a normal timeframe. Erick was very methodical & quick, yet meticulous (& didn't rush or cut corners after losing an hour to pick up correct unit) and payed attention to the details and cleaned everything up afterwards. Louis did a great job on the outside unit, new "pad", electrical connections, etc. ps... they handle registering your product, rebates and arranging the city inspector, who by the way, said it was a great installation job and loves to see installations like that.

If money is no object for your HVAC system install or repair project, Alamo Air is the company for…read moreyou. If you are a working person, or a person fighting a rare form of blood cancer like me, with its related expenses, they may not be your best option. I am giving them 2 stars, because their techs are professional, technically skilled, and product knowledgeable. It kinda' stops there, if you don't have major bucks for their work. I do find them, unsurprisingly, rapidly responsive after they submit a quote. Then, there are the coupons, with the fine-print disclaimers. In my case, a $150 "special" promotional discount vanished when we removed a short run of basic flex duct from the scope of work. No explanation was given about the discount's removal. It just vanished from the quote. Awesome HVAC company, if you can tote the note, and navigate the, sometimes disappearing, morass of their special promotions, discounts, and coupons.

We worked with Aaron today, Oct. 8,2025. Aaron and the entire team are so professional and courteous. Aaron brought to our attention that our condenser is not performing to like it should and that it will be needing to be replaced. He mentioned that we could replace it today since he had the part available or we could just monitor it. There was absolutely no pressure to have it replaced right then and there just that it would need to be replaced soon, he left all up to me. Every technician I worked have been straightforward about what needs attention. I want to Thank the entire team at Aero Design Systems. You all are a great, friendly, honest team that performs with integrity which is hard to find these days! Keep up the good work. Thank you again!

In June 2025, we hired this company to diagnose an issue with our HVAC system. After their…read moreevaluation, we were told we needed a new condenser, which cost us $5,200. Two days after the installation, the system stopped working again. When they returned, we were told there was now a hole in the coil and that it would be another $5,000 to repair or $16,000 for a completely new system. At that point, we decided to get additional opinions. Multiple HVAC companies quoted us significantly lower pricing. We learned that the condenser we paid $5,200 for typically costs around $3,000 installed. We ultimately had a brand-new system (the same model we already had) installed by another company for $7,000, less than half of what we were quoted. When we raised our concerns, the only explanation given was that they "don't get as good of pricing as other companies." Our experience left us feeling like they don't even try to properly diagnose, they just throw in expensive parts and hope for the best. We are also feeling duped because we obviously paid well above market rate for the work performed. We strongly recommend using ANYONE else.

He took dozens of pictures explained everything in detail to us and even gave us tips for maintaining our system in a better condition and preventing future problems. I am 100% happy with this visit. I also feel like it was a good value for what we got. Brendon explained everything to the point where we felt comfortable with what he found and what he repaired and we're ready to move forward by handling some of the maintenance on our own. I would highly recommend him if you get a choice of a technician when using Woods in the future.
