I requested the replacement of a couple of breakers. Mark did a great job and explained everything that he was doing. Used quality breakers, and the labor charge was appropriate considering that he came from Dallas to Kerens to do the job. I highly recommend him. read more

Mark did a great job for us rebuilding/replacing our home's outdoor water spigots and cleaning our propane fireplace logs. Knowledgeable and personable. Highly recommend him. read more

Kinda pricey but compared to the rest of the ones I've hired to work on my house, his work definitely is worthy of the price. Does it correctly the 1st time and even cleans up the mess he makes plus before he even thinks about leaving the site. I had to hire him to correct what other contractors had either not done because they didn't listen to what the job they were being asked to do was or didn't care to or know how to do it the right way. So, he would have much more cost effective for me had I found and hired him from the beginning!! read more

Mark was very responsive and was able to fix the issue I was having with my tub faucet. Would highly recommend.

Mark came out to complete a new 220v breaker installation in my garage and new wiring/conduit going outside for a new split AC system I'm installing. He made himself available immediately while many other electricians needed weeks before they could come out. The price was reasonable and I would absolutely call him again. read more

I needed help with installation of a whole house battery backup paired with a tertiary electric generator for my home. Mark has experience and knowledge well beyond plumbing and was able to discuss my project with me in an understandable way. I had questions about a specific brand of equipment that he hadn't dealt with before, and he honestly answered that while he was unfamiliar with the brand (Growatt) that he would research it for efficacy and compatibility with my goals. How refreshing to get an honest answer from a contractor! Mark came highly recommended to me as a reputable tradesman and business owner, and so far I'm impressed. I'll update this review when the project is done, but so far I'm happy with Mark's communication and professionalism. read more

The installation of a new faucet was fine. This review is based on lack of punctuality. I had an appointment at 10 AM and the plumber came 90 minutes late with no courtesy call. I had to call them to confirm if they were still coming. Very unprofessional. read more

On July 17, 2012, we suffered the unthinkable; during the height of the summer heat in Dallas, suddenly, and without warning, our downstairs AC unit stopped blowing cold air. Yes, it's true! We actually had to use fans to blow hot air around until we could get professionals to our home to fix it. We contacted Mark Masters Service Company to see if he and his team could fix our unit. We told him that we were in Code Blue and that we needed him stat! Mark dispatched one of his team members to our home the next day. The technician was polite, professional, pet friendly, and candid with us. Believe it or not, the problem was diagnosed and it looked like our unit would be saved for almost pennies as all it required was a new Capacitor switch. The part was only $25.00. In addition, he cleaned the condenser coils and added Freon R-22 to the upstairs unit. He also noted that we had a leak on the upstairs unit. For now, we decided to pay him for his time, labor and parts and count our blessings that we got off fairly cheap. What a relief...or so we thought. Later that day, the downstairs unit stopped blowing cold air and it once again required a call to Mark Masters Service Company. On July 18, the owner accompanied his team member. They did a thorough investigation and determined that they could fix it again, but it appeared that the unit was overheating and causing it to burn out the Capacitor switch. He could not guarantee that fixing it again would last for a day, a week, a month, or a year. In fact, he said it could burn out as quickly as the switch they put in the day before. We had a big decision to make, but ultimately, we decided that enough was enough and we must bite the bullet and purchase a new unit. Thus, Mark called it at 3:05 p.m. and our unit was officially pronounced dead. Mark provided us with three different quotes to select from...a low-end unit, a mid-range unit, and a top-shelf unit. We went with the mid-range unit. Mark ordered a new condenser and furnace and on July 24, 2012, he and his team installed a 16-SEER, 4-ton unit from PAYNE, complete with a new line set, new supply and return, new duct work, new thermostat, and a new filter grill. Another quality that I admired about Mark Masters Service Company is that the owner, Mark Yanez is a very good listener. He remembered me saying that I hated going in to the attic to change the 20x25x1 filter. To my surprise, he moved the location of the filter and grill so that it was now located next to the attic door. Not only would it be easier to change the filter, but I would never have to enter the attic again. That was a big plus for me and it scored major points for Mark. In addition, the new ducts would remain untouched by our hands or feet as we would no longer have to step foot in the attic, thus preserving their fine craftsmanship. Mark and his team spent the entire day installing the unit. They had a ton of work...four (4) tons to be exact, but they paid attention to each and every detail. They even came back the following day to do see how the unit was working. Then they double checked their work and ensured that they left our home looking as clean as it did before they began their work. There was so much debris from them removing the old unit and installing new ducts that they returned later that evening, with a truck, to haul off the debris. They were concerned that it would be an eyesore for us and our neighbors as we waited for the city to pick up big trash on our scheduled day. Again, it was their attention to not only the big things, but all of the little things that impressed us. We were extremely satisfied with the quality of their work. Not only was our customer experience with Mark Masters Service Company a memorable one, but we will definitely call on their services in the future. In addition, I have their number on speed dial. If anyone I know needs a recommendation for a great company that stands by their products and service, I will tell them to look no further. One of the benefits that we received from having a new AC unit installed is the fact that our electric bills have dropped by as much as 28% and we have not changed our usage at all. Keep up the great work Mark Masters Service Company. Remember, there are hundreds of contractors out there that do what you do, but they don't all do it with the same respect and care for their customers like you do. read more

Ive called Mark Masters a few times now on different jobs. I had a gas water heater spring a leak in my house that after one call and that afternoon Mark Masters replaced the unit with a quality instal. I have a rental property that had a gas water heater burst and again Mark Masters provided a quality instalation. Each time the area was thorougly dried and cleaned removing all water. Ive also used them to replace a few faulty shutoff valves. Ive never had anything less than a pleasant experience with. They are very timely and do excellent work. read more
