It can be difficult to find honest and reliable HVAC companies, but this experience stood out. I had several questions prepared about my refrigerant, capacitor, and overall system, but I found that I did not even need to ask them because Jerry naturally addressed those topics during our conversation and explained everything clearly. He also completed a detailed inspection of my HVAC closet and offered a helpful recommendation for a better filter. The service was straightforward, with a flat fee and no upselling or pressure, which I really appreciated. Overall, it was a great experience, and I will definitely be using Cold Comfort again for my annual maintenance.

chose AG Heating Cooling Duct Cleaning in 2025 because their quote was cheaper than other…read morecompanies. I paid approximately $7,900 for the installation of a new Trane HVAC system. Unfortunately, this turned out to be a very expensive mistake. The Trane air conditioning system they installed had refrigerant leaks from the very beginning due to poor installation workmanship. The company promised a one-year warranty and service support, but they never came to inspect the system despite multiple requests. Because we have another HVAC unit serving the attic and the outdoor temperatures were not extremely high for much of the year, we did not realize there was a problem until the summer of 2026, when the weather became much hotter. At that point, we discovered that the newly installed system had essentially lost all of its refrigerant and was barely providing any cooling. After contacting AG again, they finally came out but charged additional fees for leak detection. Even after charging for diagnostics, they were unable to identify any leaks. Instead, they attempted to sell me an additional "leak sealant" service for approximately $395, which I declined. I then hired another HVAC company. They were able to quickly locate two refrigerant leaks, both at the original brazed joints installed by AG. These leaks were found directly at the installation connections and strongly suggest poor workmanship during the original installation. After I provided this information and evidence to AG, the company stopped responding entirely and ignored all further communications. As a result of the prolonged refrigerant loss, I am now concerned that the compressor may also have suffered damage from operating under low refrigerant conditions. I strongly recommend that homeowners carefully consider other HVAC contractors before hiring this company. A lower initial price is not worth poor workmanship, lack of warranty support, unnecessary additional charges, and being abandoned when serious installation problems are discovered. Extremely disappointed with the installation quality, customer service, and accountability. I have photos, videos, and leak test results confirming that the leaks originated from the original installation joints. Please think carefully before trusting this company with a major HVAC installation. ------------------------------------------------------------------------ This response does not address the actual facts. I requested an inspection only two months after installation because I was concerned the system was not operating properly. The company refused to come out. Less than one year after installation, the system had lost essentially all of its refrigerant. After AG charged me $220 for leak detection and failed to locate the leaks, another licensed HVAC company found two leaks at the original brazed joints installed by AG. These were installation-related leaks, not "third-party errors." No third party had worked on or altered those joints before the leaks were discovered. The company later offered to refund the $220 leak-detection fee if I deleted my review. I refused. Instead of accusing the customer of intimidation, the company should explain why a newly installed system lost its refrigerant, why it refused to inspect the system when first contacted, and why another company was able to quickly find two leaks at AG's original brazed connections.

Our house had been serviced by the same company for at least 20 years, spanning multiple owners…read more Then they got bought by a service company that was then bought by private equity - in all those transitions I saw the upsides just fade away. So, it was time to shop around. Enter Buric. Booking appointments was easy, with multiple reminders including a call 15 minutes out. The technician spent over an hour documenting the system and doing maintenance tasks. The documentation took a lot of the time since he took photos of every part so the next visit the state can be compared. When he went to replace my humidifier pad, he even suggested I save money by buying them on my own and just keeping them near by. I ended up paying the premium and he left the box so I could find replacements more easily. It's great to not only switch from private equity to a locally (Columbia based) owned company, but to get better service at a better cost to boot.

He spent about 1.5 hours thoroughly evaluating both systems, taking detailed measurements, explaining what each one meant, and answering every question I had without ever making me feel rushed. What really stood out was that he focused on education instead of pressure. He clearly separated items into "Must," "Should," and "Could" recommendations, explained the reasoning behind each, and even took photos so I could see exactly what he was referring to. There was never any pressure to upsell, just honest information so I could make an informed decision. He also caught a weak capacitor before it became a failure, tightened some electrical connections while he was there, and took the time to explain how to think about preventive maintenance versus repairs. As someone who likes to understand how things work, I really appreciated his patience and willingness to answer detailed questions. Austin represented Buric extremely well. If you're looking for a knowledgeable, professional, and trustworthy technician, I'd highly recommend requesting him.
