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

"Work went per plan. Skilled technicians knew their product and had experience with installation. Clean neat job that was done right the first time. Removal of the old unit and air handler went as planned."

"Quick and expert service! They installed a completely new AC and furnace system for us. Reasonably priced. I would definitely recommend!"

"Of the five bids I received, Michael Bonsby Heating & AC company proposed the best value for the price. From start to finish, through removal of the old furnace to installation & operation of the new furnace, the service technician was knowledgable & experienced in doing the work, and helpful in answering questions and explaining the use and operation of the new furnace. The office staff was also responsive and courteous whenever I called with questions or scheduling of installation. I'm very satisfied with this company and recommend them highly."

"I hired someone so that it could be done correctly. I have a 3 level townhome and wanted the 3rd level pressure washed from a ladder, downward. The pressure washer did the whole house from the ground. I am aware of the potential damage pressure washing siding from the ground above the 2nd level can cause. Also they used the pressure washer on the window and water got into the home. For the price it was ok, but I wouldn't hire them again."

"Jim Farrell and North Alabama Technical Services rebuilt my computer and provided me with everything I expected and so much more.  He provided the various options in equipment, including specs and pricing, answered all our questions and helped us make the best decision for our purchases.  The computer was completed in a few days, far less than expected, the installation included clear directions for use.  The package also included a good warranty for the equipment.  I was extremely pleased with his service and would not hesitate to recommend his company to anyone with computer service needs."

"The serviceman did a great job in installing the new burner. Did it with ease."
