HVAC reviews in Silver Spring, Maryland

Thomas Clark provides premium plumbing for those of us living in old buildings. They just repaired - actually replaced - the leaking drain under a tub installed, in concrete, 92 years ago, and spent half a day doing it. We are a repeat customer because they do excellent work, on time and budget.

Tim, the plumber from Thomas E Clark, phoned 20 min before he got to my friend's apartment. He was on time, assessed the problem and fixed it, quickly and thoroughly. He left the work area spick and span, and I believe charged a fair price. What more could I ask? The service was excellent and my friend is once again able to take baths in her tub.

Davon did an excellent job working on my leaking toilet tank, particularly because of the low clearance to access it. He was very efficient and fixed the problem.

I was also very pleased about how quickly the dispatcher got a plumber out. This is a very good company. I found the pricing to be a good value.

Our insurance company requested a full examination of the plumbing in our house, and Tim quickly and efficiently filled out the relevant form.

I recently had the pleasure of receiving plumbing services from Thomas E Clark INC, and I couldn't be more satisfied with the experience. From start to finish, the technician {Alexander Covell} demonstrated a high level of professionalism, skill, and courtesy.

He arrived on time, fully prepared, and immediately assessed the issue with confidence and clarity. His attention to detail and thorough explanation of the problem and proposed solution put me at ease right away. The work was completed efficiently and to a very high standard, leaving everything clean and functioning perfectly.

It’s rare to find technicians who combine technical expertise with outstanding customer service, but Alexander delivered on both fronts. I highly recommend his services to anyone in need of reliable and expert plumbing work. A true professional!

you guys are great. everything, from beginning to end, is personal and professional.

Your phone people are efficient, courteous and helpful. They’re so unlike the disinterested and ill-informed people on most company call-in lines.

The service techs come on time, communicate in advance and get the job done with a minimum of fuss. Just love it.

Pricing, invoicing, bill payment is quick easy and reasonable.

What sets Thomas Clark apart from the rest is that it's a good company that focuses on its core business and doesn’t try to do too much. You haven’t grown so big that you lose the ability to service your customers well. I appreciate that.

We had the misfortune to scheduling a quote to replace our heat pump system from Thomas E Clark today. Maybe the sales person woke up on the wrong side of the bed but it was a disaster from the word “GO”. The sales person did not want to assess our current system, take measurements and understand our expectations for a new system. He thought it was more important to lecture my wife on our current broken Trane system. He wanted to vent about the lack of availability of Carrier products during the transition in refrigerants. Frankly, we just don’t have the time, bandwidth or professional expertise to deal with mental illness in folks posing as sales professionals. The salesman walked out because my wife did not want to hear about the virtues or lack thereof of a broken heat pump system. On the way out I could hear him taunting my wife. Thomas E Clark your sales person was unprofessional but we are happy to have experienced this because we would have hated to have dropped $20k on a new heat pump system only to find out that your company do not respect its customers. So thanks for helping us dodge the proverbial bullet. UPDATE: Yes, Kate P. we do have examples. The attached image is an excerpt from the contract for the existing heat pump system that we are seeking to replace. As you can see the SEER rating is listed as “18”. This is what we contracted for in 2012 and this is what we believe we received. We have no reason to doubt our signed contract. The “wanna be” hotshot HVAC salesman from Thomas E Clark mocked my wife for repeating what is stated on our contract, that our current system is rated as 18 SEER—which is not unreasonable from where I sit. The salesman insisted that the existing system is 16 SEER and not 18. There was no cause for the salesman who came out to give an estimate for a new system to address the old contract or her understanding of an old contract. The ego or mental illness (or whatever) of the salesman would not allow him to let the issue go after being asked repeatedly to do so. The salesman became undone and refused to complete the estimate arguing and taunting my wife on the way off our property, striking the heat pump for good measure. And Kate P. , Jake from John C Flood told my wife when he made his pitch during the quote process the previous week that the new refrigerant R-454B contains propane. When she stated this the salesman he all but called her an idiot stating that no propane is in the new refrigerant. Again, the salesman could have just told the wife to look it up herself instead of dressing her down and getting angry and lashing out at her. So, Kate P here are the examples of the unprofessionalism of the Thomas E Clark salesman.

The team, led by Daz, did a phenomenal job. They exceeded my expectations on all fronts: professionalism, communication, efficiency, quality, reliability and cleanliness. Plus the team was very friendly and worked very well together as a team. Very nice people.

On day one Daz called me to give a ‘heads up’ that he was on his way to arrive in 30 minutes, as planned. They organized in advance a ‘no parking zone’ in front of our house. Miguel, a T&C plumbing manager, joined the team and walked me through the work plan step by step. He and Daz explained what would be happening each day including measures to protect carpet, furniture and personal items from the drilling, and the removal / replacement of pavers and replacing grass in the front garden, which I really appreciated.

There was no need for me to stick around and oversee the work since I was confident that I was in good hands.

Daz sent me photos of each step from confirming the dug up connector pipe was indeed lead, to pics of the interior space wrapped in plastic up to the ceiling, holes dug in boiler room and external basement entryway, and final shots of copper pipes and refilled cement patches.

The team did the work in stages efficiently, starting at 9.15 am and ending around 1-2 pm each day. Passed the inspection in the morning on 3rd day.

I highly recommend Thomas & Clark with no hesitations.

This company came highly recommended from my realtor. Easily the best plumbing experience I’ve had. Efren is very skilled at his craft and went above and beyond.

Nervous about hiring a plumber? Don’t be! This company was fantastic. They came with the part that was needed to fix my shower because I’d explained the problem when I called for the appointment. They were very polite, friendly, and respectful (They thoughtfully removed the rug from the bathroom before starting). They were knowledgeable and quick. Andy came with a trainee which indicated to me that the company prepares its employees well. I would highly recommend Thomas Clark Plumbing company.

Had a plumbing issue come up @ 6:30 pm and put in a semi-emergency call. Had D from Thomas Clark at the house in 2 hours and the problem was efficiently solved. Will definitely use them again! It was expensive but excellent quality and almost IMMEDIATE response!!!

My neighbor recommended Thomas E Clark for plumbing and I'm so grateful for this recommendation. They figured out the source/culprit behind a leak in about 30 seconds, which was exciting after 3-4 prior plumbers couldn't crack the problem. I've called them for all repairs since and would consider for HVAC as well. Timely & accurate work at a reasonable cost and they're prompt & accurate with repair window estimates & notifications.

Ke'Von came out immediately after hearing of our concern with a tub diverter. He was even patient enough to wait at our building while we worked to grant him access to the premises. He was communicative, transparent, and helpful in resolving the matter all while saving us time and money on any unnecessary parts and repairs. Extremely impressed with his (and the company's) responsiveness, trustworthiness, and knowledge. Thank you Ke'Von and the rest of the Thomas E. Clark Team.

We have used Thomas E Clark for plumbing as well as HVAC services for over two years. We find their service to be of excellent quality, prompt and fairly priced. For emergency repairs, they can usually respond within the same day.

On November 18 & 19, 2025 workers David, Ezekiel and IBrahim with Thomas E. Clark replaced the lead pipe from the city line to inside my home with a copper pipe. The work was grueling but they did a tremendous job. They were professional, careful of the inside of the house and they restored everything back as it was ( hole covered, straw put down, patio walkway lites put back). They even installed a new water filter on the faucet of my kitchen sink because I knew I couldn't figure it out. The cost (with a special lead replacement program in DC was '0' to me. I recommend this company highely and kudos to these three workers.

I was very pleased with almost all of my interactions with Thomas E. Clark. They were personable and prompt ., and thorough in return contacts and on the day of the service, kept me well apprised of their arrival time which was right in the middle of the range that had been set.
The service lead, Timothy, diagnosed the problem near the shower headand then fixed it. He also suggested another possible fix for the other faucet and gave me two alternatives: the super one for $250 and the McIyver for free. I took the second and am very happy with it.
I will likely turn to this company first with plumbing issues in the future.

Thomas Clark did a fantastic job on site. They were respectful, quick, cleaned up after their work, amd talked me through both the problem and the solution. They completed a lead service line replacement flawlessly, and changed a long section of galvanized pipe. They were affordable and quick.

Ill definitely be returning to this team with any future plumbing issues.

Best

Thank you Thomas E Clark and DCDOE and their Lead Pipe Replacement Assistance Program (LPRAP).

With funding through DDOE LPRAP program we were finally able to get the last piece of lead out of our incoming water system.

Thomas E Clark answered our request for service promptly, sent out a project manager to confirm that we were in fact eligible for the LPRAP, received approval from DDOE to perform the work, applied for and received all permits, and performed the water line replacement all within the span of 3 weeks. From initial call to the water line being replaced.

Their crew was on time, courteous, and explain the process in exacting detail, giving us milestones for when we could expect the water to be turned off and turn back on as the line was replaced. Their house call Pro scheduling app made it very easy to communicate with the project manager as well as the technicians, and provided real-time tracking of their location and eta through the house call Pro app.

I'm very thankful to Thomas E Clark and the LPRAP program for providing this service to the District of Columbia residents.

I remember a time in DC when Department of Health came to houses that had young children and tested them for lead, I was one of those kids.

The water may taste a little less sweet after today! But at least my kids won't have to deal with this lead problem in the future. What a wonderful program.

John did a great job at a great price. He was very professional and punctual.

It takes a lot for me to leave a review but John has gone above and beyond for us not once but twice. I highly recommend; 5+ stars

I recently had the pleasure of using Elite HVAC, and I couldn't be more satisfied with their service! From start to finish, the team was professional, efficient, and highly knowledgeable.
