Mission Statement: We aim to offer outstanding services to our customers by committing to honesty and integrity, and by prioritizing ongoing enhancement towards excellence.

Over the years, we have navigated the ups and downs typical of local service businesses, always prioritizing humility, honesty, and excellent customer service. We have transformed from a small service provider in the 1950s to a mid-sized mechanical and service company today, employing over 200 local professionals. Our well-known motto is, ""United was built on nights and weekends."" We operate 24/7 to ensure our customers' homes and businesses run smoothly.
The loyalty of our employees to United is evident, with an average tenure surpassing 10 years. Our management team has been promoted from within, which helps maintain our high service standards.
With the support of our customers, United Mechanical is acknowledged as a leading mechanical contractor in DFW. David began his journey with United in 1973, starting as an apprentice sheet metal mechanic immediately after finishing high school in Garland.

David's 42 years of experience at United, along with his profound knowledge of HVAC, mechanical contracting, piping, and plumbing systems, and his steady leadership, is invaluable.
Under David's leadership, United has established a solid reputation for quality and safety in the industry. One of David's preferred quotes is that we seek to be ""not the biggest, but the best.""

Recommended Customer Reviews

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.

called sat evening at 6 PM requesting service on my a/c. i've been their client for a few yrs now and have felt very comfortable with this company. HOWEVER ........beware of an after hours service call !!! 2 hrs minimum plus the cost of the service call totaling $ 409.00 before work begins ???? OUTRAGEOUS !!!!!!! feel free to email me at ( geg1951@aol.com ) for the name and number of the company i called after calling UM. they were here in less than 2 hrs, fixed the problem causing condensor fan not to come on for $ 89.00 !!!!!!!!!
NEVER AGAIN WILL I CALL UNITED MECHANICAL ....EVER ..............

I have used United Mechanical for 3-4 years always with good success. I called them to replace my AC system earlier this year and they spent the extra time explaining some deficiencies in my duct sizes. After correcting the problem and installing the new system my energy bills have dropped 22% on average since May. The AC system cools and heats the house much faster and keeps the room temperatures very consistent and comfortable.
The service team at United has always been on time, is very professional in explaining the problem and solution, and cleans up after they are finished. I have and will continue to recommend them to all my friends and family.

Exceptional service! I was in the market for a new heating and air conditioning company after finding out my previous company was no longer in business. After talking with several friends I decided to use United Mechanical as they came highly recommended. Now I see why. From the girls in the office who took my information to the tech, Clay, who came to repair my problem I was treated like had been their customer all along. My heater was back up and working within 24 hours from calling them. Since I was so impressed with their service I signed up for their maintenance program (I was on one with my old company) and was surprised to find out they did plumbing too?!? And I get a discount?!? Perfect! My garbage disposal went out last year and I hadn't had the money to have a plumber out so while the heater guy was here I went ahead and scheduled a plumber. I just knew when the plumber got here I'd be out of pocket $300-$500 for a new disposal. I was shocked when the plumber knocked at my door at 8:30am (as requested) and was finished by 9! He was able to repair my old disposal. He said it was fairly new and just had jammed. My bill was less than $100. Wish I would have made that call last year! Overall this company has provided me with the best service I've received in years. I had no where to turn when it came to plumbers as my old company only did a/c and heating. Thank you, United Mechanical.

I had a terrible experience with United Mechanical yesterday. Not only did the plumbers stay 3 hours before determining they couldn't fix our problem, my pain meds I had as a result of shoulder surgery disappeared while they were in my home.
