United Mechanical
Company Overview
Mission Statement: We aim to offer outstanding services to our customers by committing to honesty and integrity, and by prioritizing ongoing enhancement towards excellence.
Starting in 1949, we were a small plumbing company driven by one principle: if you provide a great experience, customers will refer you. We established an air conditioning service in 1960 to support our already successful plumbing business.
Throughout the years, we have faced the challenges common to local service companies, maintaining our focus on humility, integrity, and outstanding customer care. From our humble beginnings in the 50s, we have grown into a mid-sized mechanical and service organization with over 200 local team members. We often say, ""United was built on nights and weekends."" We are available around the clock to keep our customers' lives and businesses operating seamlessly.
Our staff demonstrates remarkable loyalty to United, with an average tenure exceeding 10 years. Our management team has been promoted from within, which helps maintain our high service standards.
Thanks to our valued customers, United Mechanical has earned recognition as a premier mechanical contractor in the DFW area. David joined United in 1973 as an apprentice sheet metal mechanic right after graduating from Garland High School. David moved up from foreman to superintendent, then Project Manager in 1988, ultimately becoming President in 1997. With over 42 years at United, David's deep expertise in HVAC, mechanical contracting, piping, and plumbing systems, along with his calm and strategic leadership, is invaluable.
Under David's leadership, United has established a solid reputation for quality and safety in the industry. David often says we strive to be ""not the biggest, but the best.""
As President and CEO, David emphasizes the principle of ""do what you say you're going to do,"" prioritizing the well-being of our employees and customers, and ensuring United is the lead contractor on every project we undertake.

Recommended Customer Reviews

My experience with United Mechanical was not what I had read in the reviews of other customers. The techs were polite but they did not have the part needed to fix the toilet. They left my house and about a half hour later called me to say no local Home Depot or hardware store carried the part. They had found a store 1/2 hour away and I would have to pay for their travel time to and from that store. Since they had taken the tank portion of my toilet I had no other choice but to agree. When I had spoken to office rep to make appointment he had said charge would be a little over $200. There was no discussion of prolonged travel time to get a part. My bill was $368.65 which was beyond what other plumbers would have charged. I had asked others about their charges and they were in line with the approximate phone charge UM gave me. Unfortunately, I thought the reviews would help me find an honest company but it did not . Most companies bring the replacement part. I have never paid for travel time to get a part. I can not recommend this company

We needed immediate help to change out an old, deteriorated washer valve and assistance with updating a 3 to 4 prong plug for our dryer. I contacted United Mechanical, spoke with manager, Doug, and they sent a team out immediately. I am pleasantly surprised! David and Nathan got here and quickly assessed the situation. Provided a good, quick quote. They were kind, smart, efficient, knowledgeable and a pleasure to work with. Excellent communication skills. They were super timely. Came back the next day with parts, got the job done is less time, and cleaned up the dust and dirt upon completion. The company recommended Petri Electric (one of their commercial partners) and they worked simultaneously on the electrical outlet. In a couple hours, we were done. From the lady who answers the phone (office manager) to the supervisor, to the guys that came to the home -- they all represent an amazing company with fast, quality results and a great price. I am so grateful to work with them. We will be calling them again for additional remodel plumbing work that needs to be done. I highly, highly recommend them for any type of plumbing needs. They know how to solve customer problems. They listen and they are very respectful of the customer and their needs. Hope to see David and Nathan again soon! Way to go guys and office team! You knocked it out of the park.

Last time they came to light up our boiler, it would cost me about $200. This time they came to replace the pump blower relay ($39.50). Total cost $669. I talked to the manager. He said that it took a little over 7 hours on this job. He only charged me 4 hours. Yes, just a relay and they charged me $669 for it. OVER CHARGE. OVER CHARGE. I will never call them again.
This place is in 11540 Plano road Dallas TX

If you need a plumber, call them. Their CS is outstanding. I called them and they came out on same day, DURING CHRISTMAS WEEK! They were thorough and extremely timely. Usually plumbers leave their mess, not them. Professionals at their best.

I can't say enough about how professional the service techs are at United Mechanical. Any time I have an issue at one of my properties I contact United Mechanical and I am never dissappointed. The serivce techs arrive on time, diagnose the problem, communicate the problem and fix it! If you appreciate professionalism and quality work I would certainly suggest calling United Mechanical for your next plumbing issue or failing AC!

After purchasing our dream home, we found out there were SEVERE plumbing and air conditioning problems. Including BLACK mold and several broken pipes underground and in the walls! United Mechanical was our saving grace! Their teams worked for days, tirelessly to repair all the problems. We will forever be grateful they were able to repair everything so quickly and precisely so our family didn't have to be sick any more. All the guys were very polite and clear on the repairs they were making. They even wore booties every time they entered my home and tip toed when the baby was sleeping. I highly recommend them for you and your family!!

We have been using United Mechanical for several years. Jim is our guy. We had to call UM because our faucet suddenly lost pressure. They are fairly quick to come out. In this instance, Jim initially showed me the part I needed and told me how I could easily replace it myself. Of course as soon as I replaced it something else happened and he had to come back. He had to replace another part but it didn't correct the problem. Jim had one of the managers call us to set up another appointment-which again was timely. This time a little more work was required but they didn't kill us in the price.
United Mechanical has professional plumbers who won't stick you with hefty prices and show up in time. They don't run silly TV commercials to gain business, but clearly can generate enough customers by referral. Which is what I'm doing now. Use UM if you need help and ask for Jim. Good guy.

We have been very happy with our plumbing services and are looking forward to a long relationship with this company. They show up when they schedule, they respect our property and the price is fair.

I would recommend this company for any plumbing, sheet metal, or HVAC needs.

Less than impressed with this company. We had three major jobs to get done in our house. They completed one job which was supposed to take two days and took over a week. The other two jobs were fulfilled with promises of someone going to "call me." Not only are they over priced, but they're extremely disorganized and clearly didn't value our business. Moving on.
