I'm a certified home inspector and Nestor installed my new AC and Furnace correctly. It was a BIG…read morejob. I trusted them to completely replace our system, and they did it quickly, efficiently and at a good price. And Nestor had followed up on multiple requests I had to make a couple of adjustments so that our new system was running perfectly. It's 95F today and our new Bryant AC is running COLD air and holds it's own. I got estimates from multiple providers who wanted to rip me off because my furnace was broken on the coldest day of the year. Nestor gave me an honest quote and didn't give me excuses like "I need to do extra sheet metal work" or "your system needs a new flue". He figured out what was the best midrange furnace and AC for our house and quickly installed it so our house wouldn't freeze up. His installation was up to code. The Nest thermostat didn't work at first but when I mentioned it wasn't working, he came back the next day and fixed it. The aC and furnace he installed are quiet and energy efficient. He also installed a high quality air filter. I looked for leaks in his duct work and I couldn't find any. He correctly set up the condensate drip line to extend 1 feet past the foundation of the home. I do wish he put a more sturdy mat for my aC, time will tell if it shifts and he has promised to come back if I need any adjustments.

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.
