I was booked for that Monday! The day of my appointment, I was called several hours before my appointment to say they had an earlier than expected time slot and wanted to know if they could come now. Unfortunately I couldn't do earlier than scheduled but appreciated them asking! My time slot was 4-6 pm. They showed up at 4:05! Wow! I can't tell you how many times companies give time slots and show up hours AFTER the time frame. But not Markool! They are on it! Jorge and Jose were my technicians. They were both very friendly and went right to diagnosing the issue. After about 30 minutes, they figured out I needed Freon. I asked the pricing and they had a tablet to look up the pricing right away. If you need Freon be warned it's expensive! Not this company's fault though it seems to be commonly expensive when I looked online out of curiosity. These two technicians were knowledgeable and explained everything. They were super polite as well. They emailed me my invoice with pictures of everything they did today. I highly recommend Markool for your cooking needs!

He identified some issues, but never told me what the required repairs would be. Then he told me that the repairs would cost us 75% of the cost of a new unit. He said that the AC unit needed to be replaced and possibly the air handler and even the water heater. This last recommendation made me skeptical. I asked for a quote on the repairs and separately on the cost of replacement. He said that replacement would require another 90 minute appointment; which I was not ready to commit too. I was expecting a quote and detailed listing of the repairs. We never received this quote. Based on the technician's description of the issues, my husband and I were able consider some potential repairs on our own. We made the repairs on our own (coil cleaning, capacitor replacement) and everything seems to be functioning well so far. My concern was that AllTech immediately jumps to a recommendation of replacement if a unit is older than 10 years. We never received a quote on the cost of repair. The repairs my husband and I made required roughly $30 worth of parts. I wish that AllTech would have provided the quote for repairs and not immediately jumped to the cost of an entirely new AC system. Also suggesting to replace the air handler and water heater was excessive.

Brian from Flow "Master" Plumbing told me he needed to replace the pipe under the sink because it was too small. I have used a plumber once before, I was never told that but I was busy and so I said " do what you need to do to get the sink unclogged." These ppl charged me $550 to unclog my sink. They asked for a review, I gave them a great review. Then, the exact same sink clogs again so I called them back to fix it. It was a week-end. I couldn't stand over them again- kid has swim practice. Brian arrived unprepared had to leave to go rent a snake. Took all afternoon. Then said he "snaked" the pipe. The sink appears cleared, he charges me $700.00! My gut is saying WTF!? But I pay it. Always hopeful. Fast forward a couple weeks and SAME SINK has the same issue. Remember he charged me $550.00 the first time because he SAID the problem was that my pipe was too small. I have had my house since 2007. Never had that issue. Anyway, I contacted Brian. Told him the sink was having the same issue and that I felt he wasn't fixing the issue, just charging me excessively. I tell him he needs to either refund my money or come back and actually fix my sink. In typical fashion by those who don't care about their customers because a sucker will always exist (like me, with zero time to oversea the work) and they will always get paid, he simply blamed MY HOUSE. He had the balls to tell me my house was old (if I had a brand new house I wouldn't be calling a plumber, dipshit) and that's it. No, lets see what the real issue is, or "maybe we need to snake further out". Nothing. He then just ignored my request to fix my sink. My house was built in 1956 and completely renovated in 2012, btw. I ended up hiring a plumber from DC who came in, unclogged the sink for $250.00 and laughed when I told him Flow "Master" Plumbing told me my STANDARD pipe under my sink was too small and that is why my sink clogged. Did I mention that Flow "Master" Plumbing left a giant hole under my sink after they replaced my pipe the first time? Yeah. I need to pay someone else to rebuild under my sink now. Lesson learned. NEVER AGAIN!! Over $1,000 in the trash! Claudia Hines Washington DC
