NORWALK - With the drop in temperatures throughout the region, plumbers and HVAC specialists say they are having trouble meeting residents' demands for help with their home heating systems.

Nick Caruso, the owner of A&N plumbing, says he usually gets three to four calls a day. But in the past day, he says that number has skyrocketed and so have the hours he must work.

RPL operations manager Bob Livigni says the company is already three days behind in tending to calls.

Both men say that it's not the low temperatures causing problems, but a lack of routine maintenance since most people don't notice issues until the weather worsens.

The repairmen recommend getting furnaces or boilers checked twice a year. They also say people should replace their furnaces every 11-15 years and boiler every 10 years.
