"Angie's List reviews made me go with GAC Services for a new furnace and air conditioning unit. Five mechanics showed up early in the morning in three trucks. They were clean cut young men and very polite. They made a lay down area in my basement with blankets. They wore covers over there shoes while in and out of the house. They were very respectful of my home. They worked non stop until 5:00 PM. They had a separate sheet metal mechanic that showed up and did really nice sheet metal work. I was impressed. After a year went by my thermostat went out and they came out and replaced it free of charge. I signed up for the maintenance contract and they come out twice a year . Once in the winter and once in the summer. Another part went bad after two years and it was under warranty and they replaced it free of charge. They are honest and reliable. I highly recommend them."

"Just started working with Markool this summer and they have been fantastic! When I need service, they are so fast and every person we have interacted with has been polite, knowledgeable and personable. We unexpectedly needed to replace our system during a heat wave and they were super. So responsive and quick. I would highly recommend Markool for all of your HVAC needs!"

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

"It was pricy, but it was good service. Well, that's hard to say because it's all expensive, as oppose to any other air conditioning company, it's about the same, just too much money in general."
