Wow! What great service and terrific communication from every member of the team. I had a tricky issue, was on an "urgent" schedule due to travel, it took two visits, but all's well. Thanks so much for being super professional. I know we'll be calling you again! read more

BEWARE! I guess the DC and MD locations are tied together. I went by the ratings for the DC location when I setup an appointment. I was floored by the estimate for replacing two undersink water valves and removing old dishwasher/installing the new. $900+ I know enough to know that was absurd. Still had to pay a $99.00 charge for them just to show up. BEWARE! BE SMART read more

I was advised to use them through my neighborhood group. I'm sure glad I listened. Jason came out next day and now all baseboards are working. This is my new go to company for heat and air. Some companies don't know how to work on floor heating. They do! Fair service charge and price. Use them if you don't want to get ripped off! read more

We have used Thomas E Clark before, and so I called them to service a toilet. They came the next day, when they said they would. Davon was totally suited out in protective gear: face mask, gloves and booties for his shoes. Turns out we needed a new toilet, and he had one on the truck! He replaced ours immediately, left a totally clean space and was out the door in an hour. I call that excellent service, at a reasonable price. Thank you, Clark! read more

Terrible service and rude staff! Sent a very ill employee to fix air conditioning. Had my husband try to help him do his work. Said he was sending another employee out same day but we were told otherwise by the manager of Clark. He wanted to send back the same ill employee the next day. When I complained, he hung up in me. Horrible inconsistent service over the past 2 years. read more

I have been using Thomas E Clark for 30 years for jobs ranging from the routine to the big disasters (like having to replace all the leaking galvanized pipes in my old house). All of their employees are friendly, knowledgeable, great at explaining things, and never try to upsell you. Service is always on time,quick and thorough. Today a tech came at 8 am to do a standard winter heating checkup and saw that my water heater was leaking and needed to be replaced. Clark had it in stock and everything was finished by 11. This is a great company. read more

I am very disappointed and regretful that I called Thomas E. Clark. After paying nearly $153, my problem has not been solved. The staff people on the phone were very friendly and the plumber that was ultimately sent was helpful, but they recommended services that I did not need and did not adequately disclose the cost. Carlos, the HVAC technician who came, and did not do any work, assured me that the $104 call out fee that I paid him would be split with the plumber. This was not the case and I had to pay the plumber an additional $49. After taking off a day of work, and losing $143, I still have a leak. Be sure to ask your company if they are charging you overtime before booking anything and don't rely on dispatch people to send you correct technicians!! And better yet, go with a company that is actually available during the hours that working people are available! read more

I am a native Washingtonian, and my family previously had used and liked Thomas E Clark for over 20 years. In particular, the technician named Jason is stellar. Their admin staff and scheduling has recently gone through the tubes, and they are not worth the hassle. I recently placed multiple calls, emails, etc both during office hours and during off hours over a four week period to request an appointment with Jason. In spite of spending a lot of time repeating the story and my request, they failed to ever contact me. The people who pick up the phone fail to identify themselves, but are actually dispatchers who are utterly clueless and inept. A couple of weeks ago, and only after voicing my complaints, the dispatchers finally put me directly through the HVAC dept, and they scheduled an appointment with me between 8-9 AM this morning this AM. He failed to show up, and after multiple wait times with the dispatcher and my members of the HVAC staff, I ultimately spoke with an exceptionally unprofessional rude person by the name of Mike Hartmann. He is rude, horrible, and terrible. As a result, I will never even bother with Thomas E Clark in the future. read more

I recently had Thomas E Clark replace my HVAC units in my house and detached garage, After a thorough examination and explanation of our needs we were off and running. Everything went as explained, areas worked were clean units are working great. From the first call to the final follow up everyone was very professional and responsive. I will definitely use them in the future and highly recommend Thomas E Clark to anyone in need! read more

Pros: Fast Response Time; Professional Con: VERY expensive So I am a bit torn on this review. They were incredibly responsive and were able to send someone to our unit ASAP. The technician was knowledgeable and very nice. He recommended that we had to replace the hot water heater. Unfortunately they price they quoted was DOUBLE (more than $1000 over my other quote) than other quotes I received (for the exact same brand of water heater as the replacement). I called the Company and said if they could come down on the price I'd be willing to use them since they had been so helpful (and because I already had to pay $99 for the initial diagnosis). I was told they had zero flexibility on price, so I ultimately went with another company (who I was VERY happy with). Overall, seemingly good company just ridiculously overpriced. read more

I don't enjoy leaving negative reviews unless a company is truly horrible. In this case, I feel obligated to let others know that our entire experience with Thomas C Clark was really bad. Customer service and communication were terrible. I don't believe they were honest about their availability, which let an entire day wasted (waiting) and over time charges beyond belief. Had they been honest about how tight their schedule was, we would have called another company. They have you over a Barrell on hot days. I'm fully aware that you will pay a premium plus for almost any heating/AC company but in my 49 years, this may have been the most we were ripped off. We will not use this company ever again and regret our experience. Not sure what's worse, a hot house or being totally taken advantage of... read more

I've used Clark for plumbing for years and they always do a fine job but just had a horrible customer service experience and will be switching to a new service--given the competition in the DC area would much rather spend my money with a company that values me as a customer. I had an appointment this morning and the plumber called my landlord instead of me (though I ensured they had the right numbers when I made the appointment) and said they were at my house and no one was home. This was not true as my nanny was sitting 10 feet from the front door waiting for them and no one came to the house, nor called my house. The plumber said that since no one was home he was going to a different job and would come back to my house (of course hours later). When I called the company they said that he hadn't been to my house but that the plumber had called and no one answered and therefore went to a different job. I explained the call my landlord received and the customer service woman denied it happened. I told her I was disappointed in the service, especially that there was no apology for the fact that at minimum the stories didn't make sense and at the worse the plumber was outright lying. She refused to apologize, said that the company had done nothing wrong and that he had not come to my house and had not been able to reach anyone when calling. disappointing all around. read more

They came out to address some plumbing issues in our home. They snaked a drain, cleared a clog, and had to remove and put a toilet back in place. In putting it back, they cracked the based of the toilet and rendered it wobbly, creating even more problems. The line they snaked ended up having more lingering issues and kept getting clogged up. They gave us a proposal, but after calling for two weeks to talk about price and set up a time, George never returned our call. I left countless messages asking to speak, but nothing. Really not good nor professional ... I'm not sure where the ball is being dropped, but as a company, they should be getting back to me if they want my business. read more

I've called this place 3 times this evening, spoken to a different phone operator each time who was not able to connect me to or ask questions to the original person I spoke to. So much for a small family business. Originally it sounded like someone would definitely be able to come out tonight, the second time I called for an update (a few hours later, she said someone would be coming out. A few minutes later I got a call back and the operator told me the cost would be more since it is after hours, but they would still come out. She said she would call me back with an ETA. The third time I called I spoke to a woman who could not confirm if anyone would actually be able to come tonight. I explained that I was waiting for a call back with an ETA, and she explained that they don't call back, and said there was no way anyone from there called me. So obviously, I must be crazy. read more

I would like to update my review on this company. After receiving my letter, the company wrote me an apology letter and refunded me $100 of the overcharged amount I paid. I'm satisfied with that. I'm happy that they considered my request. I hope this doesn't have to happen to anyone else. Would I use them again..not sure, I would have to seriously consider the situation. However, I was happy because I felt heard by the company. read more

this place is a colossal ripoff. charged me $1400 to replace a $100 boiler pump (retail price, they billed it at $700) and fix a valve which took about two hours labor total, so roughly $650 an hour. Just incredible. read more

I had a fairly good experience with this company yesterday. I found a leak in my HVAC Tuesday morning. After shopping around with other companies, I decided to go with this company based upon another unit owner in my building's recommendation. The cool thing about this company is that they have a comparable hourly rate to other companies, but if your problem is not a crazy bad emergency issue - for a few dollars more than it would cost to fix your problem in on visit, they can set up a service contract with you - which covers not one, but two visits. And as I have discovered, HVAC's do require annual (bi-annual is better) maintenance. The technician who came out, Carlos, was punctual, well mannered - and explained what was going on with the unit to me in layman's terms. When I asked fora better rate, he didn't dismiss me - he put me on the phone with his manager - and we were able to come to a better agreement. For this flexibility, Thomas E. Clark will have my business for years going forward.... Honestly when it comes to contractors, its not always about what you pay - but whether you feel that you were treated fairly. I will probably upgrade my rating to 5 stars if the HVAC continues to work in good condition by the time they pay me their next visit in June. read more

Really disappointed. The advertisement says they are open til 10 - called at 6:30 with no heat in the house. The receptionist made it sound as though the office was open and someone would respond tonight. A technician called an hour later to say they could not help tonight. We are cold, frustrated, and looking for a heating service to respond read more

Used Clark since the 70. Called for a leaky faucet. Ed came and I was told I needed a new faucet and understood the leak would be fixed. The receipt for the $69 house call did not mention any additional charges for the leak. . After a week of mix ups Clark finally returned with he new faucets. Then, at the site, I was told it would cost almost another $400 to fix the leak which was the original problem in addition to almost $800 for the new faucets. The "owner" Steve was not available, there was no one els to discuss it with and they said Steve would call??? Very dissatisfied and feel as though I was rolled.. read more

Had a positive experience fixing my AC. Servicemen called on their way to say they could arrive earlier than the given window if we were available. We are in a condo building so the two servicemen went to the room to run tests on the unit. They found blown fuses and capacitor was rusting. We chose to replace them both. In addition to the work, we paid the $99 service fee. I was surprised that the service fee was not applied to work completed but what can you do? Saw in other reviews that people feel its unfair to pay $100+ for a lower priced (online) part but in my opinion you are paying for their expertise and the prompt, high-quality installation. Well worth it - happy to have it fixed! read more

used them for my air conditioner. Guy named Dan came out on Sunday service, knew what he was doing, and like other reviewers said, didn't skewer me on the pricing. Highly recommend. read more

Needed repair on my tankless hotwater boiler combo. No hot water. The first technician that came out didn't know how to service this type of unit (even though I told them it was a tankless unit). The second one knew how and isolated problem (new part needed that had to be overnighted). That cost me $300. Once part arrived, the third guy replaced it. That cost me $700. But, while the unit was fixed, the hot water wasn't getting hot enough and not hot at all in kitchen and bathroom faucets. The technician suspected a new mixing valve was needed. The quote to repair that was ....wait for it....$1,400! Said it would take 5 - 6 hours to complete. I said NO THANKS and called my regular plumber (who unfortunately couldn't do the other work because he doesn't service tankless boiler/hot water units). He bought new mixing value and replaced it in ...wait for it....ONE HOUR. Total cost: $521.97. NEVER AGAIN will I call Thomas E Clark. Suggest you don't either. read more

I can't praise or express my appreciation enough for Thomas E Clark's professionalism and standards of excellence. The company installed a large condenser unit on the roof of our house several years ago. When the AC failed to work at the beginning of the hot weather, they came out and saw that the earlier installer had not secured the unit properly and it had fallen off its platform. At the height of its busiest work period, Thos E Clark's manager said that it was their error sent two technicians to repair the unit at no charge. I would never have known that it was an installation error, and if they had charged me, I would have paid full freight for the repair. In a time when few companies pay attention to customer service or give a thought to workmanship, Thos E Clark stands out as a company of the highest integrity and professionalism. Outstanding. read more

I'm afraid I was not impressed by this company and would not recommend them to others. For starters, they are expensive. Back in August I asked them to inspect my heating and AC system. After completing the inspection and replacing several parts, i was stunned to receive a bill for $1158. They also recommended that I replace a furnace fan motor which would have cost an additional $800. Last week, while replacing the furnace air filter, I noticed water accumulating under the unit. I thought that, after the August inspection, problems like this would not occur. As such, I called the company to see if they would send out a technician to diagnose the problem and not charge me for the follow-up visit. Ironically, the company representative placed me on hold and a recorded message said "Thomas Clark guarantees its work." When the rep got back on the line she said the leak was probably a result of the fan motor which I had not replaced. I then arranged to have a technician from another company come out to fix the leak. He quickly identified the source of the leak which, as it turns out, had nothing to do with the fan motor. I believe the technician from Thomas Clark would have caught this problem if his initial inspection was more thorough. In summary, I'd only deal with this firm if you have money to spare and take their customer assurance for "quality service" with a grain of salt. read more

These guys are a great company to work with. Period. You'll be in good hands if you work with them. Hands-on President who is very mindful of the 125 year reputation of the business. There's a reason why they've lasted as long as they have, and it's not because of poor customer service. I've read some of the complaints in the negative reviews, and many seem unwarranted. 1. Complaints that they charge "by the job" not "by the hour". This is a good thing for everyone. Pricing is straightforward to the customer, and the the company is never accused of milking the clock. The 2. Complaints about the site visit fee. Again... pricing is upfront... no mystery, and you get what you pay for. It costs money to get a licensed professional to show up to your door and diagnose a problem. We do the same thing for doctors, auto mechanics ... You can't expect a professional to drive to your door, diagnose a problem for you, then allow you to call up a bunch of competitors with a diagnosis from a professional in hand. -Eric read more

I'm not normally one to leave reviews on Yelp, but HVAC technicians are exactly the type of service that your average Joe (such as myself) turns to Yelp for recommendations for, so I felt compelled to share my experience with others who have also recently had their A/C blow out. Bottom line up front: I'd highly recommend Thomas E Clark, and couldn't be happier with their service. I first reached out to Thomas E Clark on a Monday morning when I realized that my HVAC unit was no longer blowing cold air. I was contacted shortly thereafter by Mike, who walked me through a few basic troubleshooting tips to try to avoid having to make an unnecessary service call (and just as importantly, save me money!). Unfortunately his tips didn't resolve my issue, so we scheduled a technician to inspect my HVAC unit that Thursday from 12-4. When the technician arrived on Thursday afternoon, he took a quick look at my exterior HVAC unit and knew almost immediately that I had a blown capacitor. Sure enough, after replacing the part, my A/C vents began blowing cold air. The price seemed entirely reasonable (just over $200), and I never felt like he was trying to sell something to me that I didn't need (an experience I've had with other HVAC technicians). This was exactly how I think all HVAC service calls should go, but are unfortunately all too rare. My only complaint was that the technician arrived towards the end of the 12-4pm window, but he was still ultimately within that window, so I can't complain that much. Bottom line: if you're having trouble with your A/C, don't hesitate to reach out to these guys...they're great. read more

I have used Thomas E. Clark for more than 20 years and I highly recommend their advice and the quality of their work. I turn to them for regularly scheduled AC and heating maintenance and my bigger jobs (I don't call them for little things like snaking drains). They have done everything from replacing all my old galvinized pipes that had sprung pinhole leaks to just installing a new central air unit. They often send people who know you and your house from past visits. They make coordination with other companies easy, such as arranging for my walls to be restored after the pipe job or timing their visits to work on my furnace to mesh with a company called in to reline my chimney. I've never compared prices, but I've never felt overcharged. read more

Thomas E Clark is exactly what you want but would never expect from a Plumbing & HVAC company. I used them for Plumbing in the winter. The plumber snaked my drain and gave me advice but did not up-sell me on anything. Last night my AC quit working. I called and they sent someone out within 2 hours (he arrived at 8 pm) and fixed the problem in 30 minutes. This morning, the AC quit working, they worked me into their very packed schedule and the tech came back. My circuit breaker flipped (duhh!), he flipped it back and didn't charge me another service call!! Thomas E Clark's prices are very reasonable, the people that answer the phones are very polite and efficient, and the techs are great. It's nice to know there's a company you can call at any time and get great reliable service. read more

TL;DR: Book these guys; they're great. My experience with them was top-notch. LONG VERSION: A little background. My wife and I are fairly new homeowners (going on two years), and we've definitely had our share of live-and-learn moments so far. Notably, right after we bought our house, we had to have some plumbing work done. Not extensive, but enough little annoying stuff to rack our costs up to over $1500. For those repairs, we went with a local plumber/handyman. He seemed great, so we used him for the installation of a new water heater last year. That was a mistake. Not too long ago, I noticed a faint smell of gas coming from the water heater hookup, so we called these guys to come inspect it. I called them at 8.am. in the morning; they were at my house by 1 p.m. (without a "rush" fee). Erwin - who I can't speak of highly enough - came out and was the ultimate professional. Sure enough, the other plumber tightened the connection so hard that it cracked it, releasing a small amount of gas. Erwin then informed me that the flexible gas hoses used for our water heater and HVAC weren't really recommended, and it was a shortcut the other plumber took. At that point, I asked Erwin to go ahead and do a once-over of the entire water heater connection. He also found the other plumber used duct tape - DUCT TAPE! - to secure the water heater venting. That's a MAJOR carbon monoxide risk, and very luckily, Erwin had all the parts he needed to fix that issue, too. For all of that work (new gas hose installation, correcting of water heater duct work, and inspection of the unit), it was $450. I think it's a small price to pay for the safety of my family and whomever is going to rent our basement space in the future. For those of you complaining about the consultation fee, GET OVER IT. They apply it to your balance should you decide to do work with them. Plumbing work is extensive, and I agree that it's incredibly hard to give an estimate - almost always to the chagrin of the customer when it winds up being more - over the phone. There are pipes, water/gas lines, valves, etc. that all need to be evaluated for an accurate estimate, and that's exactly what Erwin did. He walked me through every single thing about my repair - including nice-to-haves, but not necessary - and the cost associated with each. That's not something you can do over the phone. I never felt pressured to fix anything that wasn't necessary, and Erwin was incredibly patient as this new homeowner asked a bunch of questions. We'll have these guys back to the house for any plumbing and HVAC service we need, including when we need those custom pipes fitted for a permanent solution in the water heater/HVAC closet. As far as I know, their work is also guaranteed, so that gives me peace of mind, too. Book these guys; they're great. read more

We had a gas leak that had to be turned off by Wash. Gas. Thomas Clark was immediately responsive after 6pm that day - although they couldn't get someone out that evening, they sent a technician by 3pm the next day. Their work was quick with no issues and reasonably priced. They were also willing to come back for free if the leak persisted. read more

My central AC crapped out the week before the July 4th holiday, and as I was out of town I wasn't able to coordinate anything till I got back - today, July 3rd. Yesterday I called these guys for an appointment. They came out today, found and showed me the problem (a dead compressor), then made a few calls and had a whole replacement unit (the outdoor fan/compressor assembly) in and installed SAME DAY. TODAY, July 3rd. Amazing - can't recommend them enough based on this experience. read more

I found Thomas E Clark here on Yelp and have two totally different issues over the past month. They were quick to respond to my call and to schedule. Both the folks on the phone I dealt with re: scheduling and the in person technicians were great! I had a plumbing issues (had to replace a temp valve in my shower) and a broken heating trane heating/air system. The fees were reasonable and the service was great. I had two different guys and both were awesome. I highly recommend there services!! read more

Clark Plumbing was supposed to meet me between 8:30 and 10:00 am and told me it would most likely be on the early side at around 9:00. At 9:15 when I had not heard from them I called and was told the plumber was "across the street." I called back at 9:40 and was told he was at another job and would call as soon as he was done. They finally called me back at 10:50 am but I had already found another plumber. read more

These guys are AWESOME! They made time in the middle of a heatwave to get my AC investigated and promptly repaired, faster than I was quoted anywhere else. My technician was communicative, unobtrusive, and friendly. I can not recommend these folks enough, big thanks to the team at Thomas E Clark! read more

I don't get some of these reviews. Thomas E. Clark has installed our furnace, fixed our humidifier, serviced our furnace and AC units all at a reasonable price (after all, it's DC people) and they've done a great job. Trust me, I've had some contractors put in new water heaters, then spring a leak, then need to service a pump...all without apology or refund. These guys are the real deal and do quality work. Always happy with their service. read more

USE THESE GUYS IF YOU NEED A PLUMBER!!!! We had a clogged exterior drain. I had called the other guy without using yelp...Boo me...the other guy wanted to start with tearing up my driveway to fix the clog and took some negotiating to get him to try to unclog it first, a fruitless endeavor at best. I called Thomas E Clark after finding glowing recommendations here and I was excessively pleased with my service encounter with Andy S. This guy and his company are top notch professionals. I told him what happened and had been happening and he went right to work. He used a vacuum cleaner, water, the biggest screw driver I have ever seen and skill to unclog the pipe that the other guy had said would need to be dug up. It seems that when the contracted who was flipping the house before I bought it has been flushing everything down the drain. Besides a heavy amount of mud and silt there were a few small rocks, a bungee cord clip, and a large rubber pipe coupler which was the base of the problem. He pulled it all out and stuck a hose in the drain...SUPRISE all the water went down and he didn't need to dig up the driveway and he knew he didn't have to dig up the driveway cause he did this thing called trying other options first. Something the other guy is apparently unable to perform, or didn't want to cause then he wouldn't have to do it and the company can charge me more. ( Don't know if you can tell but I was a little mad at the other guy) Andy also spent time telling me how to perform preventative maintenance to keep it from happening again, which equals concern for the customer. Now, Andy S. did mention that they may have to dig up the driveway and pipe, but only if the other stuff was unsuccessful, but I'm okay with that because it is an honest assessment and a professional advisement. So Andy went right to work and was successful...but the other guy took 45 minutes and said the pipe was clean and we would need to dig up the driveway cause the water wasn't going down....hmmmm curious...what was he doing then? Eh, Who cares I won't use them again. I WILL be using Thomas E. Clark again though!!! The "other guy" was played by a plumber from John C. Flood. Check out my less than pleased evaluation of them if you'd like, if not just do not use them. read more

I called them at around 6 pm because my furnace went out. The tech was here at 8:30 pm & fixed the problem. Everyone was super nice & courteous! So professional!! I will make sure to keep their information because today they rocked!!! Thanks to you & the staff for making this process less stressful on a cold day in April!!! Only downfall was the price but hey at least they helped me out & I didn't have to drag my son to a hotel for the night. read more

My system recently broke down and wasn't cooling our house properly. After an awful experience with another plumber (Rod Miller), I had T E Clark come out. First - the individual who called me to schedule the appointment (I think his name was Mark or Matt) was fantastic and provided me a lot of education about my system and A/C in general. He actually thought I had a non-issue and I may be better watching the system over the next few days. But he said they'd be happy to come out for peace of mind to give the system a full inspection. Next day: the rep shows up right on time, educates me even more about my system (so much more than the Rod Miller rep did). He was very patient in educating me on continued maintenance (as well as optional T E Clark services for that type of thing), but was also a no-pressure kind of guy. I didn't feel like I had to spend more money. He told me about the age of my system and what I should look out for in the future. He refilled the freon and informed me that if something happens again, it's likely due to a freon leak and I can test for that before replacing the entire unit. Some guys would leave that info out in hopes of coming back to sell me additional services. All done in an hour. Easy and now...nice and cool! read more

I had a low flow problem with my shower, and within days of calling Clark it was fixed. They're very flexible in timing and waived the service fee for the second day of work. read more
