""After 15 years of enduring water and flooding damage to our yard and the foundation of our house, and after trying various 'solutions' from well-intentioned landscapers that never truly resolved the issues, we ultimately decided to engage Drainage and Erosion Solutions. We required comprehensive flood control and damage mitigation, and their expert team skillfully implemented swales, dry creeks, catch basins, and channel drains in areas where water management was critical. They also replaced a water-damaged window well, removed a flagstone patio to install drain basins and drainage pipes, and flawlessly reinstalled it. The supervisor and crew displayed remarkable knowledge, professionalism, and an unwavering commitment to detail throughout the entire project. This system has been operational for several months now, and even during the most intense rainfall, which historically led to road flooding, my house and foundation remain dry. We enthusiastically endorse this company without reservation.""

"Atlas home energy solutions did an outstanding job from start to finish. They were professional, knowledgeable, courteous and easy to work with. All the crew members Ben Mott (was very knowledgeable, did the home energy audit, followed up with competitive quotes, which was adjusted to accommodate my request, offered BGE rebates upfront, patient and friendly to attend my calls and answer all the questions), Zam (Crew leader who did the exhaust fan installation), Tun (Crew leader who did an outstanding job to insulate the attic and basement), David (Crew leader who did duct cleaning and Aeroseal) were phenomenal and did an outstanding job. The end result is a day and night difference before and after the work and my BGE bill last month went down by more than $100 which is a huge cost saver. The HVAC does not run that much these days and the temperature is pretty even across the 30-year townhouse. I highly recommend Atlas home energy solutions for home energy audit and improvements."

"Summary: Company charged me $1000+ for 2 separate service visits that did not fix my AC unit; technicians and Operations Manager are not truthful about work done; Operatiins Mngr will tell you find another HVAC company when you express dissatisfaction ….I contacted Glenmont Heating and Air Conditioning since my AC unit was not dispensing any cold air. Thermometer was set to 68° however the unit temperature was reading 77-80° (note this was the week of extreme heat wave). On 21Jun2024: Glenmont technician Roderick performed a service call. I spoke to him via phone after the call to which he told me he added refrigerant to the system. This did not fix the issue and the unit continued to not dispense cold air with the thermometer reaching 77-80° despite being set to 68°. I was charged $119 for this work. Operating Manager Tim Schindle is contradicting what the tech said and claims Roderick did not add any refrigerant. I again called Glenmont HVAC for a second service appointment. This technician claimed the coil needed to be cleaned. The second technician (Eric) then falsely reported on his report the unit temperature dropped to 68° when he left when I have photographic evidence showing the temperature in the high 70s. I waited about 24hrs as instructed for the thermostat to drop and it never did and the unit continued to not dispense cool air. I then called a supervisor (don’t recall name) who essentially told me due to the extreme temperatures everyone was experiencing HVAC issues and did not recommend any follow up service. I then had several back/forth emails with Operations manger Tim Schindler to notify him after 2 separate service visits, my air conditioning was not fixed. In the end he told me, and I quote “my system is old…we don’t know the maintenance history…it is best for both of us to find another HVAC company. He did however bill me $964 for the second service visit, which did not fix my issue. I ended up having to call another HVAC company who diagnosed the problem as a compression failure/ replaced the unit and now have cold air blowing. The second HVAC company did not understand why the 2nd technician from Glenmont Heating/Air Conditioning was changing coils and said this was not necessary to do. Second HVAC company showed me the reading of the compressor unit to which I could see no charge was registering, essentially the compressor was no longer working which was the root cause of my issue. In conclusion, I’m disappointed with Glenmont HVAC and feel they sent incompetent technicians who falsified their work. When I complained to the company and expressed my disappointment with their work (or lack there of) they told me to seek other HVAC company without fixing my AC unit but charged me $1000+. Poor business acumen and highly unethical company that needs to be held accountable for cheating customers and not performing quality work."

"I highly recommend this company. They were professional, very courteous and very responsive to questions and concerns. They installed 2 BB filters and a UV purifier, and the workmanship is impressive."

"Tri State was prompt—they had a tech out within hours when our 20-year-old HVAC broke down. The repair estimate was $800–$1,200, and they also sent a salesman, Mike, to discuss replacement. Mike was courteous and knowledgeable, but, when we sat down to review the quote, the sales process turned into a bad car-buying experience. They started at $34,000, then "discounted" to $29,300—$10,000 -$12,000 higher than other quotes for the exact same unit. Even factoring in their warranty, they remained $8,000–$10,000 overpriced. Mike also claimed they were a four-generation family-owned business, but I later found out they’re owned by Sila Services, a Goldman Sachs private equity firm—which feels misleading. To their credit, canceling was easy (though I hadn’t signed a financing agreement or put money down). Bottom line: Get multiple quotes. Their pricing was excessive, and the sales tactics felt manipulative."

"Great service!"

"🚨 Avoid Len the Plumber – Negligent & Unsafe! 🚨 I hired Len the Plumber to install a brand-new water heater, but it failed after two weeks. They promised quick service but left us without hot water for days. Worse, the first technician concealed a serious fire hazard—the heater’s electrical components had actually caught FIRE and burned! A second technician finally admitted the fire risk, meaning my family could have been in grave danger. This is pure negligence and completely unacceptable. They replaced the heater but only after multiple delays, zero accountability, and putting our safety at risk. 🚫 DO NOT trust this company with your home’s safety! 🚫"

"Dan arrived on time and promptly went to work. He inspected the all of plumbing system and identified some minor potential issues. The install was clean and quick. Dan left the work area spotless when finished. I would definitely hire TNT in the future"

"Highly professional, knowledgeable and well behaved technician. Prices offered were good too. I definitely recommend the company."

"Rob and his helper did an outstanding job."
