How to Repair Heat Registers
The heat registers in your home direct the flow of air in the room. Over time the fins may become loose and start to make an annoying rattling every time the furnace turns on. The only way to repair noisy or broken heat registers is to replace them. The design of heat registers prevents any kind of meaningful repair. You will need to remove the register and measure the opening for a replacement. Most big box hardware stores carry replacement heat registers. Does this Spark an idea?
