The installation of new ac ducts went very smoothly and the workers cleaned up after finishing each day. I would highly recommend Green Collar to anyone needing duct replacement or repair.

The owner of the company provided our estimate, the team arrived within the time windows predicted, they were competent and courteous, and they did a *fantastic* job modernizing our system to heat quietly and evenly throughout. They added a vent to a bathroom that had been inexplicably left without one, improved the insulation throughout, and added an attic walkway for safety. We've been tolerating very uneven temps and noisy vents for the past 10 years, and I wish we would have discovered Green Collar sooner! It is *NICE* in here. I have no reservations about recommending Green Collar's services. Stay warm, y'all!

Jacob and Bryan did an excellent job on my spring HVAC check-up. Since I had a new system installed…read morejust a few months ago (by Service Wizard), it was reassuring to see everything running perfectly. They took the time to thoroughly clean the condenser and ran multiple tests on the attic unit to make sure everything was operating as it should. What really stood out was how they walked me through the entire process at the end, showing photos and explaining each step. It gave me a lot of confidence in their work and attention to detail. I'm very happy with this company and would highly recommend them.

**1/5 Stars - Big Waste of Time (and almost a lot of money)**…read moreI wanted to like Service Wizard, but my experience with them was incredibly frustrating. My AC condensation pipe was completely backed up and needed to be flushed. Their tech arrived on time and seemed very professional, spending about an hour and a half working on the unit and inspecting everything inside and out. However, he couldn't find where the evaporator line exited the house. His solution? Install an external pump and run a whole new drain line. The rough estimate for that was, well, a hell of a lot more than the $15 fee they charged me just to come out and take a look. When he left, I still had the exact same broken AC, was stressing over an exorbitant bill to fix it, and somehow found out I'd been signed up for a $15-a-month service plan that entitled me to another check-up in six months just in time for winter. Hoping to just get it resolved, I reached out to Service Wizard via Yelp later that evening to see if they could come back today to do the work the tech recommended. I never got a response. Frustrated, I called a different AC company. They actually answered the phone, sent technicians out right on time today, and those guys spent **five minutes** at my house before finding the external line, repairing it, and flushing my system. Problem completely solved in under five minutes, and the fee was incredibly cheap compared to the massive quote I got from Service Wizard. I will definitely be canceling my $15-a-month contract with Service Wizard and won't be recommending them going forward. Save yourself the headache and call someone else!

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!
