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 great. I have a very old boiler and they send out knowledgeable mechanic to to the check up for it. And once the worker didn't know, another came in and fixed it. They deliver my oil and are very efficient."

"NATS responded the same day that I called them and picked the computer up at my home. Several days later, Mike called and stated the service to be performed, ensuring the size of the replacement hard disk drive, and provided the approximate cost. Within a week (Memorial Day weekend was during this period), Mike delivered the computer back to my house. I was pleased that Mike had not only reloaded Windows 7 (I had to input my own product code), but he had also spent the time to download and install upgrades to Windows 7."

"They did an excellent job and replaced our heat pump and system in one day when the tempature was 22 degrees. After it was turned on they adjusted and balanced everything so it was perfect. They are an excellent professional company."

Install Boiler FAQs, answered by experts

A home radiator works by using radiation and convection to transfer heat throughout your home. Electric radiators use metal to conduct heat and warm the air, which then rises to warm the room. Steam and hot water radiators work with a boiler and piping system to pump thermal energy throughout the home. Hot water radiators use a boiler to heat the water before circulating it to the radiator, while steam heating radiator systems convert the heated water to steam before circulating it out. When the water or steam cools, it travels back to the boiler to be heated again.

Some high-quality steam boilers come with 10-year warranties, but a well-installed, properly maintained model can last at least 20 to 25 years. Learning how to clean a boiler, getting an annual professional service, and keeping up with maintenance and repairs on your heating system are all important for getting the most out of your model. 

Due to fuel line connections and venting complexity, professional installation is required for safety and efficiency.

If you hear your radiator clanking even when it’s turned off, it’s typically because there’s trapped water or air in the system, causing a pressure buildup. When you hear significant clanking, popping, crackling, or banging in a radiator that’s turned off, you’ll want to bleed the pipes or call in an HVAC specialist to deal with the problem (and prevent it from happening in the future).

Installing a boiler requires training, a specific skill set, and extensive experience. Boiler installation can be extremely dangerous, as it involves working with water lines, gas lines, and electricity. For this reason, it’s strongly recommended that you hire a professional to install your boiler. Some states even consider it illegal to work on a boiler without the proper licensing.
