Boiler had been giving me trouble and then quit. To make it worse we use the boiler to heat our domestic hot water too so no heat and no hot water. Couldn't reach the boiler installer so after the great experience we had with Lancaster installing our AC I called them to see if they could help with the boiler. Lancaster sent a tech immediately to check on us. Methodical trouble shooting and direct discussion with the manufacturer to confirm repair steps. Very friendly and attentive service. Excellent communication.
