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!

Unlike some home service providers, he respected my home and did not leave behind a mess of any kind. I highly recommend Everest for AC service or dryer vent cleaning!

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!

He was able to replace and fix the system within 30 minutes. He was full of knowledge concerning HVAC with lots of tips and information about my system. He even invited me to take a look in the attic and explained some of the features. Another example of outstanding customer service far beyond what was expected. Will definitely call Advanced for any further HVAC problems.

The technician returned the next day and, instead of standing by the original repair, blamed the attic's humidity and tried to squeeze another $300 out of me. After charging me nearly $600 the day before, they wanted even more money for a problem they clearly failed to fix the first time. Eventually, the technician repaired it again at no charge. Unfortunately, that "repair" was just as worthless as the first one. I also requested an itemized receipt so I could submit the repair for warranty reimbursement. They never sent it. No follow-up. No professionalism. No accountability. Now, only one week later, my AC is out AGAIN. So, to recap: * Nearly $600 spent. * AC failed within 30 minutes. * Attempted upsell for another $300. * Failed to provide the requested documentation. * AC failed again a week later. This company took my money, failed to properly diagnose or repair the issue, tried to charge me more when their repair didn't work, and then disappeared when I needed paperwork. If you enjoy wasting money, sweating, and dealing with excuses instead of solutions, then Honest Air Conditioning is the company for you. Otherwise, save yourself the frustration and call another company.
