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.

Unfortunately, my experience over the past year caused me to lose confidence in the company. My scheduled maintenance appointment was missed during the confirmed service window, and I had to call to find out what happened. On another occasion, a plumbing appointment was rescheduled after it had already been confirmed, creating unnecessary inconvenience. During a later service visit, I received repair and maintenance recommendations that seemed far higher than what I ultimately found elsewhere. While everyone should get multiple estimates, the differences were significant enough that I decided to seek other opinions. The most disappointing part was the customer service. I completed a satisfaction survey, emailed management twice, and was promised follow-up calls that never came. As a long-time customer, I expected someone to take ownership of my concerns. That never happened. The technicians I interacted with were professional and courteous, so this review is not about them. It's about the company's lack of responsiveness when a long-term customer raised legitimate concerns. After 15 years, I canceled my maintenance agreement and moved my business elsewhere. That's something I never expected to do, but the trust that had been built over many years was lost.

The main problem and downside is that they are very expensive and overcharge. Despite the Yelp page saying that the company provides a "free estimate", I was quoted $49 for the technician to travel. In addition, if I had not chosen to go ahead with the repair, the company would have charged me an additional $150 diagnostic fee. Essentially, despite the yelp profile stating a "free estimate", it will cost you closer to $200 to get a quote. I see this as false advertisement. In addition, when the technician concluded that the problem was the capacitor, I received a final quote of $600. When I googled the price of the same capacitor online, the price range was in between 75$ - 150$. Essentially, they are charging a premium of at least $450 per replacement for a single part (capacitor). Despite their professionalism and quality work, I do not recommend this company for the reasons stated above. If price is not a concern for you, and you would rather pay twice the market value for a job then you should definitely choose them. EDIT: I actually googled the price of a capacitor and offered to buy my own. I was told that by the technician that if I purchased my own capacitor that the company would not install it. In conclusion, they did not address any of my concerns. Unfortunately, after reading the other bad reviews, there seems to be a consistent pattern of discrepancies between what they tell customers and what they instruct technicians to say on site. Making an honest living is so much more rewarding than making it dishonest living.

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.

Beware of Shady Practices - State Inspection Concerns…read more I took my car to this Liberty station for a Maryland State Inspection on September 11th, 2024, and unfortunately, I had a very questionable experience. Before handing over my car, I thoroughly checked everything myself and was confident that the car was in great condition. However, after the inspection, I received a call from the station manager telling me that my 3rd brake light (the center light) was out and that there was a leak with one of the rods. I was shocked because I had just checked all the lights, and everything was working fine. When I asked about the cost to fix the alleged leak, I was told it would be over $900. I decided not to go through with the repairs and picked up my car. A few days later, I took it to another nearby station for a second opinion. Before dropping the car off, I checked the brake light again and discovered that the 3rd brake light had been pulled out of its housing and clipped. I couldn't fix it immediately due to a fractured hand and informed the second station about it during the dropoff. My car had actually failed the inspection only because of the brake light--nothing else was wrong with the car, and there were no leaks. After fixing the brake light, I returned to the second station and my car passed the inspection without issue. The whole experience from the Liberty station felt extremely shady. I'm concerned that they were trying to overcharge me for repairs that weren't necessary and even fabricated the issue with the brake light. ***Like I said earlier, I checked the car out before dropping the car off. For anyone who isn't mechanically inclined, I would strongly recommend being cautious when dealing with this station. I don't know if this is a common practice here, but it's certainly left me with serious doubts about their honesty.

In morning I did some online research to see if I could fix it myself sooner. I believe I could have fixed it (I'm pretty handy and have these kinds of tools already) IF I could have gotten my hands on the part I needed for $12 from Home Depot or similar. Amazon delivery was a day or two away. Got a call to say he'd be here in 20 minutes, so I tabled that thought. Walter came and showed me my air filter was dirtier than I expected, so I replaced that on the spot. He then replaced the exact part I was going to (so I was sad I didn't just do it myself, but again it would have been 24-48 hours later to get my hands on it). The compressor should have just kicked in after that but evidently there was a loose electrical connection, which he troubleshot and fixed quickly. Everything fired up and he checked the Freon level, which he said was fine. Cooling is working now as it should be. Walter told me to keep an eye on it and let him know if any other issues come up, as compressor could be damaged from running broken before the fix. Price was reasonable, though not anywhere near what it would have cost for me to fix it myself. But considering it was a Saturday morning (and I started looking for repairs on Friday night) for "emergency service" it was the same as what a competitor was quoting me for service "sometime" on Monday (non-emergency service). So, by this standard, which I suppose most homeowners would use, I judge it to be pretty reasonable. Walter was professional, friendly, and courteous. Only other thing to mention is paying with a credit card is 4% more. So I paid him with a check.

The documentation took a lot of the time since he took photos of every part so the next visit the state can be compared.

I ended up paying the premium and he left the box so I could find replacements more easily.
