Heater duct work often runs under the flooring in the crawlspace of your home. A flooded crawlspace can cause water to enter your duct work. If the problem is severe enough, the water will block the heater duct causing hot air to NOT be delivered to a room or rooms. Depending on where the blockage is, it may even block the entire home's heat delivery and actually cause the heater to stop working altogether. Puget Sound Waterproofing can fix your drainage system and eliminate the problem. Give us a call today.
