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!

DO NOT RECOMMEND! I was a loyal, fully paying customer of…read moreGreen Leaf for over a year and a half, and my experience was defined by poor workmanship, broken promises, and a management team that ultimately let my warranty expire rather than help me use it. My issues started in April 2024 with a faulty tankless water heater installation, one of their own technicians later told me the crew had failed to install all required parts. That crew was subsequently laid off. Water was dripping from the exterior pipe and pushing into the attic. After significant back-and-forth, the symptoms were addressed, but the root installation failures were never formally resolved. During my Fall 2025 HVAC tune-up, a technician identified that the supply plenum from my original 2021 HVAC installation was undersized and improperly installed, something never flagged in any prior Green Leaf service visit. I followed up by email requesting next steps and never received a response. A year later, they were quoting me over $4,000 to fix an installation error that their own team had been servicing around for years without disclosing. The most serious issue involved my HVAC coil. In Spring 2026, my refrigerant was found to be low. Rather than immediately discussing a potential warranty claim on the coil, which would have been the right call, Green Leaf charged me for a refrigerant refill and pushed a $300 diagnostic fee. After weeks of back-and-forth, a UV dye test confirmed a visible leak at the top of the indoor coil. By then, Green Leaf had already terminated the business relationship and refused further service. At no point did anyone at Green Leaf ever mention that a coil replacement might be covered under warranty. They collected their charges, ran the clock out with delayed diagnostics, and walked away once the leak was confirmed. The one genuine bright spot was former Office Manager Michelle Lewis, who was consistently professional and communicative. The contrast between her service and what I experienced from General Manager Thos Graham, who shifted terms between emails and ended the relationship when I asked reasonable clarifying questions, was significant. I paid every invoice in full, renewed my membership, and gave Green Leaf every opportunity to make things right. What I got in return was a company that prioritized its billing over my best interests. Find a different HVAC and plumbing company!

I had some water leaking out under the closet in my garage where my furnace and hot water heater…read morewere. I got 5 or 6 companies to come by and look at it. As it turns out, I had the original HVAC system that came with this house, which was 28 years old. Our single story 3BR/2BA house had two air returns right in the middle of the house and it was the one feature I didn't love about this house because of how loud it was. You could hear it go on in any room of the house and especially in the living room when watching TV. I have decent surround sound and the noisy system was quite annoying. Price came over the next day and after I got prices from a couple of other places I decided to go with Stan's. They had a good price and I needed the work done quickly, as not having A/C in the summer isn't fun. I gave them the job on Thursday afternoon. Friday morning two teams of two came. They took out my old system (which was working) and removed my hot water heater. Then they replaced the shelf both were on and determined the water was coming from a slab leak (the second we've had in our house over 15 years). I decided to go with the most expensive system, a variable speed system from Carrier. They assured me it would be a lot quieter than my previous system. That was very important as we're planning to stay in this house forever or until we die, whichever comes first. Roger and Ruben installed the new system. Aaron and Armando installed a new hot water heater (my old one was 11 years old and it didn't make sense to put it back in). By 2 or 3 in the afternoon I had hot water and A/C. The slab leak was capped off and I didn't have hot water to my kitchen sink for the moment. I could not believe the difference. I had had no idea such quiet systems were available, I'd have replaced it years earlier if I knew. On Monday Aaron and Hugo came back. They lined the inside of the crawl space under the shelf with foil coated foam and that quieted the returns even more. They ran a new hot water line into my attic and down through my pantry wall to the sink. My wife and I are THRILLED with this new system. The two people I've showed it to (including a neighbor) were also astounded at how quiet the system is. It's like we're living in a totally different house. Instead of coming on at 100% and blowing really hard, this system runs at a lower pace more regularly. It also keeps the temperature much more consistent throughout the house. Stan's will be doing all of our HVAC maintenance and plumbing as well. We're very happy clients!

I am leaving this review only after exhausting all direct channels with management over the past…read morefour months to get basic installation issues and documentation resolved. In May 2026, I hired Stan's for a complete HVAC system replacement totaling over $12,000. Within the first three months of operation, the brand-new system suffered two complete shutdowns due to installation defects: May 22: The system completely powered down due to loose wiring at the thermostat. July 25: The system failed again in peak summer heat. A technician discovered loose high-voltage wiring at the disconnect box that caused the wire to overheat, requiring the wire to be cut back, a shorted contactor to be replaced, and refrigerant to be adjusted. While technicians responded to the emergency calls, the follow-through and quality control have been exhausting. The post-installation quality inspection failed to catch these wiring hazards. When official service reports were generated, critical details were omitted, photos of the outdoor unit were copied into unrelated checklist fields, and technician summaries were left completely blank. Management acknowledged in writing that operating refrigerant pressures were missing after the July repair and promised a technician would return to complete proper diagnostic testing, but no one was ever dispatched. Written requests for official labor warranty paperwork on company letterhead were also left unfulfilled. When you invest in a premium system, you expect dependable workmanship, thorough documentation, and reliable follow-through. Instead, this has dragged on for months with unresolved safety and technical oversights. I would strongly suggest looking elsewhere for a major replacement.
