Service tech, Brendon, cleaned our gas furnace and pointed out an issue with our igniter that it was wearing. We are so pleased that they really go over the unit and catch these things. We are proactive people and would rather replace things now then have it break at midnight on a cold night. Always great customer service tech's that have great respect for the owner. We would advise anyone looking for a trustworthy business that Piccirilli would be the business to call.
