We are a small family owned Heating, Ventilation, and Air Conditioning (HVAC) company located in Sharpsburg, MD. The business was started in 1989 under the name of RW Harrell's Pump Service Inc. when Diane Harrell and Ronnie Harrell purchased a well pump and water system business from a gentleman that was retiring. Ronnie had worked in the HVAC field from the time he had graduated from high school so it was natural to add HVAC to the services that this new company would offer. Ronnie and Diane built the company by word of mouth and continue to grow the company in this manner. Additional DBA - Harrell's Services. Additional fax - 928-492-8004

"Donny and Phill arrived on time installed floor protection and shoe coverings and did an excellent job in far less time than I expected. I would recommend Tri State for installation and maintenance of HVAC systems."

"I had some issues with my 10 year old furnace and started looking into issues. I used to work for Carrier as an HVAC researcher and tried to fix the issues myself. I disassembled the burner and tried to get things right. In the end, I exhausted options and gave up on repair. I called my serviceman, trying to have the furnace repaired. He recommended getting a new furnace or replacing the whole HVAC since it was more than 10 years old. My serviceman gave me a quote for a Carrier furnace, which I thought was high since I knew the price of the unit (ex-Carrier R&D engineer). That was when I decided to look around. I received three quotes after reading through reviews in google and Angie’s list. In the end, I chose ARS Manassas by virtue of their overall competitiveness. In any business, it takes two things to win a deal: trust and value. In my case, one salesperson, Cliff Allen (who I will talk about more in a minute) delivered both aspects, which made the decision easy. Since I know the HVAC system in and out, I had many detailed (and even tedious) questions, to which he answered professionally with knowledge and courtesy. He did not try to upsell anything. In fact, he recommended to check a few things for repair, even while giving quotes for me. Although I decided to get the new one in the end after trying a few more attempt for repair, Cliff earned my trust and respect in the meantime. He tried to provide an optimal solution in terms of price and performance, which was more competitive than the other two quotes. I ended up getting 16 SEER performance series furnace and AC. Cliff truly knew what he was doing during the selection process. He answered all the questions an ex-Carrier R&D engineer raised and provided several quotes for comparison, which helped me to reach a satisfactory solution in an efficient and rational manner. He never tried to upsell, clearly understanding customer’s side. To the contrary, he did his best to give me the best deal without compromising performance. His professionalism does not stop at sales. He went over all the items in the specifics of installation, meticulously jotting down any notables in the contract. I was not surprised to see the technicians, Michael and Melvin, show up on time and finish the job, following the specifics and notables that Cliff had prepared at the contract phase. They tried to make the installation smooth and went over every single item to make sure that it was done to perfection. About a month later, the town inspector came out and made sure that the unit had been properly installed. The inspector confirmed that the job was done to the standard but pointed out that it would be better to add another bracket to the outdoor unit so that it would not move around. I called ARS to inform the findings of the inspection. ARS has promptly scheduled another visit (even if they could have waited for AC checkup in the late spring) to fix the issue. This time Jeremy and Josh came out and meticulously fixed the issue. These two gentlemen really knew what they were doing. They went a lot further than just adding a bracket. The outdoor unit is so sturdily attached to the bracket now that even a hurricane would not shake the outdoor unit. My kudos to Jeremy and Josh. I will come back and write a further review in 6 months to report any issues I experience but for now, I am glad that I chose ARS Manassas for new HVAC installation. If you ever need a new HVAC near Manassas area, the choice is simple. Go for a trustworthy and knowledgeable man that would deliver the best value for your investment, Cliff Allen at ARS."

"They do a great job. Had a furnace installation and ongoing maintenance over the years. We have never had a problem. Very professional and qualified."

"Jim did a great job. He quickly assessed the problem and then took our unit with him to work on it more. When he got back to us, the fix would have cost more than it was worth. He gave us options for a new or refurbished PC. We felt the refurbished was a good deal and chose that. He came back and set that up and we are very happy with it. He then took a look at my laptop and again took it along. He tuned it up and installed a speed upgrade we wanted. Of course, we paid extra for the new unit and upgrades, but we thought the price was very fair. Jim seemed very knowledgeable and responsive. We will definitely call him again if we need any computer services."

"I gave an A rating, despite some bumps on the scheduling. The A rating was earned by Danny and the work he did to get the various new light fixtures installed, both inside and outside. We have more fixtures to be installed, and we will have Danny back to finish the job."

"We just finished put bathroom remodel and used Larry and sons at three different times during the project. Tyler did the initial plumbing, replacing our old lines and fixing some leaks. Next up was Andrew and he installed the bath light fixture, ran new lines and installed an exhaust fan and new gfi outlets. We finally got someone to move our vanity upstairs so we had Tim come out to install it and a new toilet to complete our remodel. All three were excellent and professional. Would definitely recommend Larry and Sons!"
