    I used McCarthy Services for the first time in the summer of 2016. My air conditioning unit in Washington, D.C. had gone kaput and I asked some people in my rotary club, "Who do you guys recommend for air conditioning?" One of my colleagues could not stop saying great things about McCarthy. So we used them for our brand-new air conditioning unit in D.C. in 2016, but then when I wanted to get the annual maintenance package, by the time I was ready to sign up for that, they weren't servicing D.C. anymore because D.C. is like that. Now, I live in Virginia. When we needed an air conditioning inspection, I said, "Oh, my gosh, I'm so excited. We get to use McCarthy again." We have the annual inspection now.

    Our bedroom air conditioning unit was not pumping cold air, but my husband thought that it wasn't the problem. An inspector came on Wednesday afternoon and the gentleman noticed that not only was that unit not pumping cold air, but we had another unit in the basement that handles half of our house and that one was completely rusted. Once we got one hot day this summer, it would have gone kaput. The sales guy was able to come at 6:00 and he was really good. However, I don't know if it's because I was a little hangry because it was dinner time, but he could have talked faster. I was like, "I understand that you have a spiel that you need to go through. This is how the company wants you to handle things, and so I will respect that. But just skip to the bottom line."

    The price was very fair. It wasn't like a new air conditioning unit is only $12. The former owners of our house were very high end with everything and the sales guy told me the price if I wanted exactly the same unit, which is more expensive than a new car. He said, "But if I lived here, I would do this other one," which is significantly less money, but still a great system. He was very honest and he wasn't trying to upsell me to get too much. By 8:00 pm, I had already signed up for the new air conditioning system and they came on Thursday morning to install. It was wonderful and our bedroom is now cool.

      My furnace had been on the decline for a couple of years, and the AC unit was having blower issues. They were purchased at different times, and it was best to replace both of them instead of doing it piecemeal again. I decided to do it since I was going to use my tax refund to purchase it. The in-person visit from McCarthy Services was exceptional. The representative 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 technicians who came out were very professional. They kept the workspace clean, removed all the old equipment, and provided quality service. The only issue was that, apparently, when they brought the furnace down to my basement, a piece of one of the concrete stairs was broken. I didn't find out until later. But overall, it was a good experience. I found another company with a lower bid, but it was for a different unit. And the brand of the unit McCarthy estimated was more recognizable than the other one.

      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.

      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.

      McCarthy had a kiosk at Home Depot and a special offer of 0% interest for an HVAC replacement. So, I signed up with them. They did a total replacement for me but they messed up the loan. So I ended up getting 3.99% interest rate and had to spend a few months getting that sorted. But they eventually got it sorted with my staying on them. Also, they were kind and quick. I referred my grandmother to them because her unit stopped working. She had hers replaced and they were very kind to her too. But they overcharged her and I'm still waiting for a call from them regarding her credit. So while they do good work, their office leaves a bit to be desired as there are still issues pending and I can't get them resolved. And it's been a month now.

      I just bought a house and the air conditioning was not working. I got a full replacement and a water heater through McCarthy Services. I saw their ad on social media. I first signed up just for service and their guy came out and said that it wasn't any good so it looked like I needed a new system. The technician showed us a picture that said, "What have you all been doing to this system?" Even though when they replaced it the next day, I asked to see the old system and it did not match the picture that he showed me. I told him, "You've already diagnosed it. You've only looked at it five minutes." He said, "Just 30 years of experience."

      The air conditioning just did not work when I purchased the house, but I didn't know whether it needed to be replaced or just a part was missing. I was gonna get at least three estimates until McCarthy offered me a better price from the original offer. That was why I went with them. I knew how much systems cost and I was replacing a hot water heater. I'm glad I did go with them, but I just didn't like the technician.

      So far, all my experiences have been good with McCarthy Services. The most recent one was just preparing for the summer. We did the tune-up of the HVAC system before going to the summer months and running the air conditioning. The representative I worked with was kind and professional. The service visit went well. It was quick. They ran through the inspections. They gave some recommendations on what we could do to improve the unit, and then they walked me through on how to do owner care and some preventive maintenance on it as well.

      McCarthy's team members have always been polite and professional. They wear the booties over their boots when they're in the house. So, I've always had good experience with them.

      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.

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.

      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.
