Too many lead-generation sites profit from skilled tradesmen while pushing up customer costs, often promoting whoever pays them the most rather than the best companies. At Trust One, they refuse to take part in that system. We’d rather focus on honest pricing and quality work than pay a cut to middlemen.

Avoid this company at all costs. They installed my boiler but made basic mistakes that required multiple visits to fix, wasting my time and causing unnecessary stress. On top of that, they misled me into signing up for a membership over the phone without disclosing the cost—a shady and unethical business practice. If you value competence and honesty, look elsewhere.

Trust 1 Services came through! I now have heat and am very pleased with their work. Matt personally came to my home to assess the issue and sent the final team to complete the job. Jacob, Alyssa, DJ, and Tom (special side shout out to Nick) worked diligently to discover my heating issues and resolve at no extra cost. Thank you and Happy New Year!!!

My hot water tank sprung a leak for the 3rd time in the 12 years since I've owned this home so I opted to install a Combination Hot Water Heater/Boiler system to avoid continuous basement flooding. I hired Trust 1 Services to install the new system in September. I paid $23K for the system along with a filtration system to avoid/minimize sediment deposits. After they were done, I had hot water and they confirmed the heat worked as well, by showing the thermostat's ability to control the furnace, but since it was still very hot outside, it was not kept on to show the pipes were actually getting hot. When I turned my heat on for the first time on December 1, 2024, nothing came on. They sent 2 techs (Jacob and Alyssa) out to look at the issue and added a pump to the system to push the water through the pipes. After draining the whole system and individually bleeding the heat pipe in each room, they were able to get my entire second floor working (2 bedrooms and 1 bathroom). The first floor bedroom and bathroom also worked. The living room, dining room, and kitchen were not working, however. The tech (Jacob) replaced the bleeder valve in the living room and told us to give it a week to see if the air works its way out of the system, and if it didn't, they'd return. They also asked that we find the bleeder valve for the kitchen, which we did. After a week, I called back to let them know that it still doesn't work and to come back out to see if they can bleed it some more. They sent out 2 more technicians (Torrel and Brandon) to bleed the system, but they said the bleeder valves in the kitchen and dining room needed replacing. The cost to replace would be $760, and even if they were to replace the valves and bleed the system, it still may need a second stage of work costing approximately $2,500 more. The 2 techs (Torrel and Brandon) said they'd have their service manager, Matt, call me to discuss the details. I called to speak with Matt later that evening but was told he had left for the day and that they'd leave a message for him to call me. Days went by and I didn't hear from Matt so I called back, and so did my boyfriend. Again, we were told by their receptionist, Jeanie, that Matt was unavailable and that she'd have him call us back. Nothing. It was nearing some very cold days so I became desperate. I called them and scheduled to have the 2 bleeder valves replaced. Robby came out to complete the job. I paid $760, but the heat still didn't work afterward. Robby said that he believes they installed the pump on the return line, when it should be on the supply line, but since he isn't a plumber (neither was Torrel, Brandon, & Alyssa...unsure about Jacob) he would speak to Matt and some licensed plumbers to find a resolution. Again, it's been another week and I have yet to hear from anyone. My boyfriend called to speak to someone today because after reviewing the pipes, it appears they may have completely flipped the supply and return lines, causing the pressure issue on the first floor. Low and behold, Matt was in a meeting and yet again, and he was told he'd call him after lunch. Several hours passed after lunch to no avail, so I called them and told them I'd hold to speak to Matt...and again, Matt was nowhere to be found. It appears they are just evading our calls now and since we are now in the thick of the winter months, I need to have this resolved as soon as possible. They were supposed to have bled the lines when it was installed in September, but they never did that. I have a 3-year parts and labor warranty with them so I should be covered for this issue. Not to mention, the system never fully worked. I don't think I'm asking for too much having paid $23K for a machine to sit in my basement and look pretty and not do what it was meant to.

DO NOT use this company! Complete ripoff. Needed garbage disposal replaced with same one. Had booked them to come before hearing from 2 local plumbers who would have charged $250. Trust one charged $500!!! They would not lower charge at all. They were already there so I paid but they just shouldn't be in business

Arrogant, ignorant, and incompetent. Do not hire Anthony and his company (currently called Trust1, but changed name: recently was called Mound Mechanical and who knows what before that). I've had three projects done by them and want to share my experience, just sticking to the facts: Job #1) they fixed a slowly leaking toilet supply line. I'd give them 3 stars. Okay quality, but failed to put a decorative cover (called escutcheon) before connecting the pipe - rookie mistake, so then he had to cut the cover in order to put it on, which now looks ugly, but okay whatever. Job #2) immediately after fixing the toilet leak - went to install a whole house water filter. And I'm kidding you not - grabbed the filter without washing his hands and installed it. I have a photo of a dirty thumbprint on a DRINKING WATER FILTER left after not washing hands after fixing the toilet supply line. One star at most. I'll drop the fact that he did not configure the plumbing the way that we agreed on and then Anthony had to fix it and route it correctly. One star. Job #3) this is where the biggest issue and money spent is. They installed a high performance mod-con boiler and an indirect water tank. Shortly after the installation it started locking out (no heat in the middle of winter!) and Anthony has personally been gaslighting like there's no tomorrow. I've heard every single excuse from somewhat ridiculous (it's doing what it's supposed to do), to ridiculous (just hit reset, it's air in lines), to the ones that were laughed by every single other plumber I talked to (you need to have your propane tanks at 40%!). Turns out he didn't have a combustion analyzer to diagnose the issue. Long story short, the system started locking out again for a different reason and he finally "fixed" it. Except that now I'm burning through two 120-gallon propane tanks every other week during the cold spell and the house is well insulated and not a large sq ft. I got fed up with them not replying to messages and called the manufacturer, who put me in touch with a distributor, who connected me with another HVAC company. They diagnosed the issue, found two separate problems (1 - sensor that came with the boiler was not installed; 2 - hot water tank is not taking off heat as needed). After I told this to Trust1 they sent a tech who did nothing, then said they need to come back to do a fix. And then after a week of not hearing from them I finally got a hold of Anthony himself who said that he refuses to honor the warranty on labor and parts he promised because "someone else looked at the system". Long story short - STAY AWAY. This company will gaslight you, will not honor their word, and you will end up paying hundreds or thousands to fix it.

IT WAS TERRIFIC. THEY WERE PROFESSIONAL, THOROUGH, AND REALLY KNEW THE NAVIEN HEATING SYSTEM. I WOULD DEFINITELY USE THEM AGAIN AND RECOMMEND THEM TO OTHERS. I ALSO THOUGHT PRICES WERE REASONABLE.

Quick in-person quote on several heater options. Lowest cost vs. at least 3 other offers by a significant margin. On time, fast install. Also found a problem with the main heating system while installing the indirect water heater and fixed it pretty cheaply the same day.

Excellent each time.

Mound Mechanical fixed the problem in one visit and it's been working perfectly since. The problem turned out to be electrical and not that straightforward to fix, but in consultation with an electrician he efficiently completed the repair. He very much stands by his work and I've not hesitated to recommend him to our neighbors.

They were punctual, arrived as expected gave me a timeframe and finished a day early. They also picked up the debris and finished clean. They were also knowledgeable, professional, customer service oriented and reliable.

Terrible service!

Since moving into my place 3 years ago, I've had issues on and off with my Navien water heater. I've had other companies claim to "repair" this issue in the past, but perform dishonest work. Thankfully I found Mound Mechanical. They responded quickly to my request, arrived on time, and provided an honest assessment of the situation. They then fixed the outflow on the flue vent for my unit to enable proper exhaust and improve the function of the heater. They performed the work quickly and efficiently, and didn't charge me the full amount provided in the estimate, since the repairs took less time than initially scheduled. My unit is finally working seamlessly for the first time since I moved! Big thanks to Mound for providing honest quality work. I'd highly recommend working with them.

It went excellent. He was very professional, very well spoken, very well mannered, very clean in tidying everything and very professional and I will be using his service down the road again.

Each job was completed with extreme care and attention to detail. Work area was cleaned after each job. Issues to be addressed were discussed and suggestions offered. Anthony, owner of the company, is a very well-mannered, calm and helpful person. He inspires confidence. I just recommended him to our neighbors.

They were vey great, fast and clean. They did a good job and I will use them again.

Everything was great, a very good team. Very responsive. No issues it was a great experience.

Anthony was great to work with. His pricing was fair and he did some great work on a renovation project. The following was completed very quickly and passed inspection with flying colors. Complete kitchen plumbing (including gas range) Tankless water heater Outdoor shower Moved heating vent Laundry plumbing (including gas dryer) Toilet flange replacement

Anthony installed: ➡️ new, wall-hung, @LochinvarCorporate Noble, 95% efficient boiler ➡️ 40-gallon storage, Heat-Flo tank ➡️ @BoilerMagna residential, heating system filter ➡️ @Ecobeehome, smart WIFI thermostat He is punctual, professional, very knowledgeable, and provides excellent customer-service!

Anthony and his crew are amazing and very polite. Got the work done quick and didn’t break the bank.

It went extremely well. They were extremely punctual and very communicative. They did exactly what they said they were going to do with no fuss in exactly the way they said they would. Extremely neat, and by using email for appointment reminders, quotes, and billing, it just made the process quite easy.
