Top Heating & Furnace Contractors in Rockville, MD

United service s installed new new infinity carrier systems and found several punctures from a new roof install all in 24 hrs from my phone call. Professional and punctual something not often seen these days in the service world. Complete trust in diagnostic and install capabilities

Paul was very professional and the work was completed quickly. I would certainly recommend them to anyone!

Sean Cohen is very professional, arrives on time, very knowledgeable, was able to diagnose the root problem and fix it within short time. The price is very reasonable. We will definitely seek his service again.

Very good experience. Owner & crew were professional & knowledgeable. When they came across an unexpected situation (outside pipes encased in concrete), they solved it & let me know the issue. Price remained the same as estimate. Replacement of central a/c & furnace took just about 6 hours. Would definitely recommend Tetteris and would use them again. Great price!

This company went above and beyond my expectations! Very courteous and professional. I will use them again and i'm telling all my friends & family to do the same. 5 Stars! Thanks again Luis!

Replaced the screens quickly and did a great job. I'm satisfied.

We called David Stiffler to fix five outlets that had suddenly stopped working. Turns out, they came back on just before he arrived. He came, checked the wiring, found nothing but was very thorough and plans to come back if the failure recurred. Did not charge us.

Washing machines are much like computers - sometimes they just need to be unplugged. ;)

Jordan was the tech who came out to see our AC unit. He is extremely knowledgeable and was willing to explain the entire process of troubleshooting. To try and fix our AC unit, he had to replace the breaker box outside troubleshoot any further. The office scheduled a follow up appointment, and Jordan came on time and quickly replaced the electrical box which revealed the AC compressor was shorting out and had to be replaced. So as of today, we are waiting to see if Choice Warranty will quickly approve so we can get the AC unit replaced. On a side note, the company seems to be very prompt and engaged with their customers. I have had no complaints hence the high ratings and really hope our AC unit can be replaced soon!

The Contractor came in and went right to work and I felt confident in his work.

Very experienced

Tech was very professional and friendly. Although he tried to sell me additional services he was honest about the need. He was courteous about my property. He was careful to put shoe booties on so he wouldn't soil my carpet. Overall a great experience.

Sergio is very clean when he works, he explains everything to me in a clear way that is easy to understand, he is very professional, and a good worker

He is a trustworthy guy and sticks with the work to completion.

Felix came to my home to install 3 low profile electrical outlets underneath my dry bar cabinets this morning. I have under cabinet outlets under my kitchen cabinets, so I wanted them in the dry bar area also. Felix was punctual and professional. He did a great job in installing my stainless steel outlets. Felix did some upgrades to my other electrical outlets in my basement area also. I had taken estimates from other electricians, but Three Brothers Services, LLC offered the most affordable prices for my project. I would definitely recommend this electrical service to friends and family.

It was a wonderful experience with a professional technician to do the repair. I highly recommend them and will use them in the future!

Good service

Mannix's service was timely and excellent. The a/c and furnace installation went very smoothly, and the county inspection afterwards was successful. Highly recommend.

Good service

Martyn was very honest with his assesment and explained carefully all the option we had for our boiler repair. He was always courteous and very professional.

Efficient work also added material to keep from happening again.

Mario was amazing! He got us set up with a new ac system quickly and he and his team were super kind and responsive throughout the process. I’m so glad we made this hire and would absolutely recommend.
