"Great installers precessional and respectful"

"Sean, Shane, and Adam took good care of us for sales and installation. Great work, and a speedy installation."

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."

"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."

"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!"

"New part was found and technician returned the next day to finish the repair. Boiler works!"
