"BELTWAY AIR COMFORT SERVICE is a terrible company. Horrible customer service. Incompetent technicians. They came to my home when my AC broke and 13 days later still no update. I called and texted repeatedly and got no response from the company. It's been two weeks in the sweltering heat we still have no AC. First they said they had to order a part, then I they found out they hadn't put the order in for the part. The dispatch was rude and claimed he didn't know who the owner was when I asked to speak to him. I found out these are the same ripoff artists that misdiagnosed my mom's HVAC resulting in her buying an entire new unit for over $10,000, and then the unit kept shutting off because the real problem was a regulator for the gas line. They're incompetent and unprofessional."

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
