23.3 Condensation Line Clogs The Homeowner is responsible for annual cleaning of the condensation lines that extend from the air conditioning coil. Under the Limited Warranty, the Builder, for a period of one year, will correct condensation lines that clog. HOME TIP To prevent condensate lines from becoming clogged, Homeowners should follow the manufacturer’s instruction for maintenance and keep mulch, leaves, and other debris away from condensate lines’ outflow. As part of regular HVAC maintenance, the condensate lines and evaporator coil should be inspected by a professional HVAC contractor. 23.4 Refrigerant Line Leaks The Builder, for a period of one year, will repair refrigerant lines that leak during normal operation and recharge the air conditioning unit. 23.5 Insulation Uneven or Missing Thermal insulation is dictated by local codes or state energy guidelines, and the Builder will install insulation in accordance with these applicable guidelines. The Builder, for a period of one year, will take appropriate action to correct insufficient insulation installation. 23.6 Ductwork Noise When metal is heated and cooled, it expands and contracts. The resulting “ticking” or “crackling” sounds cannot be avoided. A booming noise caused by sheet metal billowing in or out (“oil canning”) will be repaired by the Builder for a period of one year. 23.7 Vibration From Heating or Cooling Equipment It is normal for heating and air conditioning equipment to generate some noise and vibration. Under the Limited Warranty, no corrective action is required.
23.8 Metal Rattling at Registers, Grilles, or Ducts Air moving through registers, grilles, and ducts makes noise and is normal. Duct systems are not designed to be noise-free. However, metal rattling from the registers, grilles, or ducts is not normal and will be repaired by the Builder for a period of one year. 23.9 Ductwork Separated or Detached The Builder, for a period of two years, will reattach any separated or detached ductwork not caused by the Homeowner.
SECTION 24: Plumbing 24.1 Drainage Problems
The Builder, for a period of two years, will assume the responsibility for clogged sewers, fixtures, and drains where clogged sewers, fixtures, and drains are the result of defective construction or workmanship. 24.2 Water in Pipe Freezes The Builder, for a period of two years, will make necessary corrections to ensure that plumbing pipes are adequately protected against normal anticipated cold weather (except undrained exterior faucets). Faucets will break if hoses are left attached in freezing weather, and are not warranted. The Homeowner is responsible for maintaining the house temperature at a minimum of 65°F during cold weather and draining exterior pipes and faucets for protection.
