If you are looking for a HVAC Contractor, a Plumbing Contractor, or an Electrical Contractor to provide you with great service, you've come to the right place. We provide heating services, air conditioning services, plumbing services, and electrical services to our customers in Frederick and the surrounding Counties, the Pan Handle of West Virginia, and Northern Virginia, from our offices located in Frederick MD. With 3 generations of experience in providing heating, air conditioning, plumbing, and electrical services, we are dedicated to providing the best possible products and services for you, and your family.
"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."

"UPDATE: My previous review still stands from a couple years ago for that specific plumber only - but my most recent experience has been a nightmare. Will never recommend this company ever again. They definitely have changed since my last experience. Not only did the plumber they sent (12/9/24) not do anything to make any effort to clear a clog ( I won’t be petty and provide a name, even though I should) - after signing agreements and I asked if I should pay now -he said I probably should so he could get started - I know I should’ve just sent him on his way, but wanted to get this fixed (astronomical for what was -or in this case wasn’t done- and was told that prices had gone up a lot since my previous experience). He also had to inform me that normally they send the new guys to do this type of work ( implying unclogging drains was beneath his “expertise “). Then proceeded to tell me he was convinced it was a collapsed drain (after snaking the drain for less than a few mins)and that I probably had water flooding under the foundation said he needed to get a hold of their camera guy to be sure - he went to his truck to call him came back in, about 20-25 mins later to tell me he couldn’t get a hold of their camera guy and left a message for him. He then said he would try one more time with the snake - did the same amount of effort as the first time and said we would have to wait until he could get a camera down there and that we would have to let the drain dry out a bit so it would probably be the following week. Packed up his stuff and said I should call him in an hour to see if he heard from the camera guy (why should I do the calling for follow up??) When he left, he seemed to struggle backing out and damaged our lawn (have security camera footage). I called the company the next day and was sent to voicemail (left a message that said I had some concerns but didn’t leave a lot of detail) and was told that I should hear from someone that day - I did not. Called the next day and was told by the supervisor of the phone people that the phone person should have told me it was 24-48 hours before a manager would respond and she would not allow me to speak to anyone else. I did not hear back from anyone in 72 hrs, so I called back and then was told that the manager was out (conveniently). I gave up calling them and called another plumbing company who fixed the issue in a short amount of time (no collapsed drain, just a good ol’ clog). Decided to call Len the Plumber one more time ( 12/23/24) 2 weeks AFTER my original call and was told that there was a note in my file that said the mgr did call 3 days prior to this call (there had been no conversation or missed calls or voicemail received by me - so either he called a wrong number or this was a lie) and in the notes the mgr (Brian, I was told by the phone person)stated that I was told about the pricing and that was it. Not sure where he got his information of what he thought my issue was, since I didn’t leave a lot of info when I spoke to the phone people other than it was frustrating to be told I would get a call in 24-48 hrs. This last phone person said she would send an email to all managers with my concerns and would hope someone would assist. No response. (12/28/24). Think twice before using this company. It has changed ownership twice since the original owner- history has shown as ownership changes in companies , so do priorities and not to the benefit of the customers."

From minor leaks to major mishaps in both residential and commercial properties, we can address all your plumbing problems. SJT Plumbing has created longstanding, trusting relationships with customers throughout Maryland. Give us a call today.
"The service tech came to my home and did an assessment of the issue. Found the leak in the gas line, showed me where it was leaking. He told me what needed to be to fix the leak, gave me a quote, got his tools and started working. The whole process took about 30mins or less and he was done. I checked my burners to make sure the gas was flowing properly. Everything was put back in its original place and there was nothing to clean up afterwards. Great Job. I would recommend this company again."

"Hot water issue. Technician gave estimate for hot water tank replacement of 8 year old lightly used tankless. In light of the phenomenol price tag, did some homework. Hit the reset button. Fixed. Hmmmm. Maybe it was the tankless that confused him. Really glad it was a free estimate (unlike Len's who charged me $315 and didn't fix it)."

Spring and fall offer the optimal time for scheduling an installation. Cooler weather means crews can work more efficiently without the summer heat slowing them down, and contractors often have increased availability between peak seasons. You’ll also avoid winter storms that can delay roof work. If you’re targeting a tax credit for the current year, aim to have the system running by December 31 so the credit can be applied.
Most systems recoup their post-tax-credit cost in six to 10 years. Your exact payback window depends on local utility rates, the amount of sunlight your roof receives, and the amount of energy you use. The higher your electric bill, the faster those panels work off their price tag. Add in the 30% federal tax credit and any state incentives, and you’ll start seeing true savings even sooner.
You can count on most panels to produce power for 25 to 30 years, and many monocrystalline models keep going for closer to 40. Thin-film options sit on the shorter end at 20 years. Staying on top of annual cleanings and quick repairs helps every panel reach the high end of its lifespan and protects your investment along the way.
Yes—if your system is properly sized, you can power an entire home with solar energy. A solar power designer will look at your yearly kilowatt-hour use, roof space, local sun hours, and whether you’re adding battery storage. When those pieces line up, the panels can cover all of your day-to-day needs and bank extra energy for nighttime or cloudy days.
