“I’d like to give a big thank you to the entire crew at Mainline. I installed my own Central Boiler with the detailed instructions [design] provided by Mainline. I was able to do the work myself. I did, however, have a million questions… and Mainline handled all of my questions professionally and never seemed to tire of my calling. I would recommend Central Boiler and the capable crew at Mainline for anyone interested in alternative heat for their home. Thanks again.”

“I needed to find out whether or not it was a good idea to shut off the pilot light in our Regency propane fireplace insert when it would not be used for several months. A short while later, the service manager called and left a long and detailed voicemail message carefully explaining the pros and cons of leaving the pilot light on or off, and he was able to give me an estimate of how much gas the pilot would consume if left on. I really appreciated the quick response and clear and detailed explanation. Thanks.”
