chose AG Heating Cooling Duct Cleaning in 2025 because their quote was cheaper than other companies. 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.

Ask the Community - AG Heating & Cooling

Do you work with specific HVAC brands or are you brand-neutral?

We work with all brands

You were recommended for installation of a Blueridge (Alpine) mini-split system to heat and cool an approx 10x15 ft addition which has very poor heat/ac with the way the contractor initially built out the addition. Is it a good product? Can you help?

We don’t install that brand / are not familiar with its quality

Hello I will like to have installed the new unit ? You serviced my old unit in January . I had been told that it should be installed in March or April. I will like to know if you think the Trane is a good brand and where I can buy it o you can buy it

Good evening i do not recommend trane . In our field it has a saying “ a trane is hard to stop but also hard to start “… we can give you some quotes on brands that we trust . These brands are the brands that you will most likely see installed in…

McGinley to my rescue! Yesterday I heard a bang and my electric went out. Some lights came back…read moreon but others didn't. I went to the basement to check the circuits and discovered water on the floor around my heater and my new Thermostat also had stopped working. I called McGinley HVAC and spoke to Ryan and he quickly got me on the schedule for the next available technician. In about 45 minutes Charles arrived and immediately got to work on the leak and replacing the thermostat (which got fried from the power surge). My electrician wasn't calling me back so I asked Charles if he or McGinley had any electrician recommendations. He gave me the electrician's name and I called him. Within 15 minutes he was here and he found what was causing the power outage issue and fixed it. Words can't express how grateful I am to McGinley's team for their prompt and efficient service. Their kindness, compassion and outstanding service is appreciated. It is so reassuring to know McGinley is there for me and I highly recommend them!

Bobby was on time and professional. He answered all of my questions and offered information that I didn't even think to ask about. My system is 14 years old but has been maintained well. A LOT of other places will try to upsell you if your equipment is 10+ years old. Not This company. Bobby showed me two items that do need attention, but weren't critical enough to need to be replaced TODAY. I'll be inviting him back to complete the system by the end of the month for sure. Many thanks! RWW

Bill F Terell Sheaf…read moreand Jordan recently visited our home for the second time in one week. The first time was to install a whole-house surge protector, connect a new electrical connection from the outdoor overhead electrical lines down to our meter in the basement and move the electric meter from the inside of our house to the outside front wall of our 2-story rowhouse (an additional fire protection upgrade). A week later, they returned to do some finishing safety-focused touches that were difficult to integrate into the first visit. Specifically, they: - rewired a single outlet in the living room with older wiring that was apparently missed in the 1980's when the house underwent a comprehensive electrical upgrade. The upgrade included adding AFCI circuit protection and running a new circuit from the panel - added GFCI protection and replaced faulty tandem switches in basement for washer and dryer - added GFCI protection and replaced faulty tandem switches in 2nd floor bathroom to remediate faulty functioning of heat lamp and fan - replaced existing two 3-way switches for upstairs hallway and and one in bathroom - AFCI circuit protection for the Homeline circuit panel Terell and Jordan appeared to have done an excellent job. Their teamwork, professionalism and obvious technical knowledge, experience with older houses and confidence was, like in their first visit (but moreso), obvious and appreciated. Terell in particular has a great touch with the client, exuding confidence, a great sense of humor and a desire to provide superior service to the client. He and Jordan make a great team. The two of them powered through the entire job in less than 3 hours (versus the 4 + estimated time to complete). As far as cost, the entire job, including the cost to obtain and coordinate post-job City of Philadelphia permits, came in at a very reasonable $1,000. Perhaps because we'd already sunk several times that into the first, more significant upgrade a week earlier, several items on the bill were discounted. Given the hours of highly skilled labor by the team, a couple fairly expensive equipment items and the fact that (pending City inspections) a fully modernized electrical system, I'm satisfied with the value Gen 3 provided on these two jobs. My overall experience (including a conversation with Amy about the Gen3 maintenance plan which I am definitely getting after satisfactory City inspections) was a 5+ stars. Highly recommended. Good people.

He was thorough, professional, and took the time to make sure everything was running efficiently and safely for the cold weather ahead. Highly recommend Jacob for anyone looking to get their system tuned up before winter!
