My unit makes so much noise it interferes with my sleeping and listening to TV. What can I do?

• Old units and some cheaply built new units can be quite noisy. Here are some very effective solutions:

• Noise from the indoor blower
  i. Be sure your new blower has sound deadening insulation.
  ii. On vertical indoor units, the return air opening into your home is often just 1ft to 2ft from the high-speed blower. Additional noise reduction can be obtained by attaching ductboard to a surface that the blower noise must reflect off of. Ductboard is a 1” thick fiberglass board used in field fabricated ductwork.
  iii. In a metal duct system, install a section of flexible duct made from Mylar in each noisy duct.
  iv. Use variable speed blowers
  v. Use multiple stages or levels of cooling (2 compressors or one 2-speed compressor) and 2 stages of heating.. These systems run at low, quiet speeds over 80% of the time. In Trane’s lineup these are:
  · For natural gas heated homes: XL19i systems with the XV95 Variable Speed furnace for multi-stage cooling and heating. An XV95 Variable Speed furnace or XL95 furnace will provide 2 stage heating and may be used with any cooling system.
  · For electrically heated homes: XL19i heat pump systems with the Variable Speed Air Handler for 2 stage cooling and 3 stage heating. For 1 stage cooling, 2 stage heating: use any Trane heat pump system.
   
• Noise from the outdoor unit
  i. All new Trane outdoor units are likely to be much quieter than your older unit. The XL series outdoor units are extremely quiet. These are usually suitable for setting on the patio.
  ii. Trane’s Scroll compressors are quieter than other types of compressors.
