    I needed a toilet replaced. It was an optional repair. I just wanted a new toilet. I reached out to McCarthy Services, and the service visit was fine. It met expectations. They showed up on time, which is great.

      The air conditioning wasn't working on one of my rental units. The young man came out quickly and he was very friendly. But he gave me bad news that there wasn't anything he could do and that I needed to replace the system. I asked for a quote, which he could not do. I paid the service fee because he had gone out there quickly. One of the salesmen went out later to get me a quote, but they didn't send it to me right away. I had to keep calling them over and over before I got it. Also, the office couldn't send it to me, for some reason. It had to be sent directly from the salesman. Finally got it, but it was more than double what another contractor had quoted. So, I went with the other contractor. But I didn't have any problems with McCarthy in terms getting someone out there right away. That was great. It's just unfortunate. If it had been something he could repair, I'm sure the tech would have done it, but it just wasn't. Overall, it was a pleasant experience.

      I contacted McCarthy Services when my AC stopped. It was quick and easy. However, McCarthry said the unit can't be fixed. It's always about, "You need a new machine. Can we send someone to give you a price on a new machine?" It would be nice to try to give me better options on fixing it rather than going right into replacement. Other than that, I appreciate a dedicated sales rep that I've been working with. Whenever I have issues, I just talk with him about it.

      We've been with McCarthy Services for a couple of years and it has been very good. The guys were courteous. They cleaned up. They troubleshot everything well. We had them out to replace a hot water heater and that went well. But they didn't get the plumbing right. They had to come back and fix it. They replaced the HVAC system here and that's performed very well and they did it pretty promptly. The only issue with the system is if there's a power outage, the air conditioner stops working properly. You have to turn the system off. We had a problem with that for a couple of days. But the guy came out and explained that it was under warranty. That's a problem with the air conditioning unit itself, not with their installation.

      We're very satisfied and they did a good job. The guys were very knowledgeable and skilled. However, It was painful to handle the scheduling and on a couple of the things we had done. One of them was when the AC is not working right, they were supposed to come out in the morning , and they let go until noon, and let us know that they gave us a new window for the afternoon. Finally, the guy called us at 4:00 on a Saturday afternoon and said, "We can't make it out today. I'm in Northwest DC. It's too far to drive. I'll be there the first thing in the morning," but they didn't show up. We called them again and we got them there Sunday night. That was aggravating. I think they overscheduled and once he's at a stop, he can't come. McCarthy needs to communicate that. The only way we found out what was going on was we had to call back our number, and she had to call dispatch, and sometimes they would get dispatch to call us directly.

      I needed to replace my HVAC system. My furnace was on the decline for a couple of years and the AC unit was having blower issues. And because they were purchased at different times, it was best for me to replace both of them instead of doing it piecemeal again. I decided to to do it since I was going to just use the tax refund funds to purchase it. The in-person visit with McCarthy Services was exceptional. The guy was very clear in explaining their services. He showed me the various options to choose from and I wasn't pressured at all to make a decision that day. They emailed me the estimate and I contacted two other companies to compare the estimates. I was able to find a company that was able to give a lower bid, but it was on a different unit. In terms of the unit that McCarthy gave the estimate on, I thought that that brand was more recognizable than than the other one, even though it was at a lower price.

      The technicians that came out were very professional. They kept the workspace clean and they took all the old equipment out. So, I didn't have any issues. They provided quality service. Apparently, when they brought the furnace down to my basement, and I didn't find out later, that a piece of one of the concrete stairs was broken. Other than that, it was a good experience.

      I called McCarthy Services because they originally put in the HVAC systems that I had at my house. I had a lightning strike that caused some damage in the house, and the HVAC stopped working. I wanted them to come out and tell me if they could fix the problem. Their tech was on time and professional in his appearance. However, he misdiagnosed the system and said I needed thousands of dollars of parts when it was only a couple-hundred-dollar part. Also, the part that he recommended replacing was wrong. He ended up recommending that the whole system be replaced.

      McCarthy came out and offered to put in a new system for $24,000. The system that they had put in, which was still under warranty by them, was a $6,000 system. They installed that exact system eight years prior on a 10-year warranty and offered to replace the one system for $24,000 for 100% increase in costs. Consider somebody else who's not trying to steal from you.

      I had my water heater and three AC units replaced. I had a problem two months ago with my AC. Some guy came and said, "This is what's wrong." The equipment is still under warranty. He said it was the controller that was bad. I'm an engineer. I doubt that was the problem. They said it was $1,700 to replace it so I called somebody else. I asked, "Can you take a look at it?" I didn't tell them what was wrong and they said it's a blower. They came the next day and replaced the blower. Everything is okay. It was much cheaper compared to what McCarthy Services was. They have these vans that look the same. Their branding is good but they're expensive. Also, they said they will call me tomorrow but never did.

      The technician who came for the A/C Tune Up advertised by Home Depot was on time, knowledgeable, and thorough. About a week later, my A/C stopped working altogether, so I texted the tech who returned, did an evaluation and proclaimed that it would not be cost-effective to repair my 20-year-old unit. I tentatively agreed. He arranged for a salesman (Maneeb) to give me a price quote on an entire new system.

      After a lengthy pitch and presentation on his laptop about warranties, reputation, etc., Maneeb asked me what my budget was for this job. I said I didn't have a "budget" for it, because I had no idea what current prices might be. I told him I just wanted his best and final estimate, because I intended to get at least three other quotes. Finally, I got him to spit out his price: $21,673.

      I took a deep breath and said, "You must think I'm a total idiot." He never blinked. He then said he might be able to work with me on the price. He asked me again what my budget was. I said, "Nine thousand dollars." He blinked this time. "Where did you get that number?" I said, "Same place from which you pulled out yours. Surely you must have a senior discount or a military discount." He calculated 5% for each of those on his computer spreadsheet.

      He got his manager Mike on speakerphone. Manager says, "Since it's the end of the month, I can get you another 25%, but that's only good if you sign today." I laugh. I tell Maneeb, "We're done here." I don't care what kind of price you give me at this point. I'm not doing business with your company." He's astonished. Final answer? They quoted me $13,000 and Maneeb says he can “take care” of the $4. So, within about six minutes, the price drops $8,673. A company that can make a fair profit at $13,000 but adds 67% more to their price as PURE GREEDY PROFIT deserves to have no customers at all.

      There must be—in order to keep McCarthy in business—too many people in Fairfax and Loudoun Counties who have more money than brains. If you need a new HVAC system for your home, go to www.Checkbook.org and find a reputable company. I did, and three other companies quoted me prices within a couple of hundred dollars of each other. . . WITHOUT first attempting extortion, profiteering, or exploitation.

      Epilogue: two days past, then Maneeb called to ask me if I was ready to move forward with my new HVAC replacement. (Yes, he really did.) I laughed and said, “Yes, but it certainly won’t be with your company.” BUYER BEWARE.
