Our boiler decided to stop working on one of the coldest days so far this year (-16 with the wind chill -20+). We called Laird and Sons at 5:30 p.m on Friday evening and their after hours technician was at our home within an hour and our problem was solved on the spot. We have called upon Laird and Sons in the past and they have consistently provided excellent service. A big shout out to Noah who got our (very old) boiler working in no time. Thanks so much Noah!
