During the cold winter months it is crucial to make sure that furnaces are working properly. Owen Golay, owner of Golay Heating, Cooling and Refrigeration in Pleasantville, says that the first thing people need to do is make that the filters are clean so that air can flow through them, otherwise the consequences could be disastrous. He adds that it is also important to make sure that external pipes, vents and regulators are not plugged with frost or icicles. Golay says that these are simple checks that homeowners can make themselves in order to prevent service calls and dangerous situations in their homes.
