Having problems with your Air Conditioners ?

Air ducts are noisy

\015 The air ducts in my central air coditioning system are noisy. I'd like to know why and if there's a way to fix it.\015

Answers :

Most folks when talking about noise means it's coming from the return air or intake. Is this correct? Please advise.\015\012\015\012RepairUSA
Many heating/cooling ducts are metal, so they conduct noise quite readily from the air-handling unit to your rooms. To break the conduction of sound, you can have a heating contractor insert flexible insulation ductwork between the heating/cooling system and the ductwork runs.\015\012\015\012If you hear a pinging or popping sound coming from the ductwork, this may be caused by thermal expansion or by air blowing past a loose flap of metal. Track along the duct runs, listening for the sound. If you find it, make a small dent in the sheet metal to provide a more rigid surface that?s less likely to move as it heats and cools.

I have an air exchange system in my house. I also have a dehumidifie set up with it to remove the humidity in my house. I want to make sure he set up the system correctly. He has the fresh air going into the air exchange and it ducts out to a "T" duct. fresh air goes to the house and also goes to the dehumidifier. the dehumidified air goes to the air exchange to a "T" duct that is mixed with the stale air from the house and is connected to the air exchange that appears to go through the air ex

Airflow We have a new ducted PEH-MYB reverse cycleairconditioner. We set the temperature at 20 degress for heating. Once it reaches it it then blows out cold air. We have had someone come 4 times already to fix various problems. It is not nice to sit near a duct and feel cold air. I thought the air flow was meant to stop, then start uo again when the temperature dropped just like our gas heaters? Am I wrong?

I have a Lennox heating and air system. It's 5 years old. The tape that hold those long tube things together has failed and the tubes are disconnected from the vents that blow air into the house. I have used duct tape as a temporary fix. I'm told that when winter comes that my duct tape will come apart. Where can I buy the right tape to put everything back together? I have tried to get contractors to do the work, but so far they are all booked up for weeks. My electric bill is sky high probably

Sounds like a lousy job. Best tape is alluminum. You can pick it up at Home Depot or Lowes. If the tubes are flex duct be sure to pull back the outer insulation and tape just the inner lining ... Air Conditioners

Noise I just bought the 8000 and 10000 BTU Frigidaire air conditioners just before my move and have found that they are very noisy (especially the 8000 BTU unit). The sound of the air flow is very noisy and the 8000 BTU unit also seems be have a slight irritating whining noise. I was thinking about taking out the three screws I saw on the side of the unit in hopes of getting the front off and attaching some cloth or something inside to make it quieter.

I have a new motorhome and the air conditioner only reduces the inside air temperature by 2 degrees on a hot day. e.g. outside air temp 26 degrees inside temp 29 degrees. After 2 hours of a/c running with door and windows shut inside air temp is 27 degrees. Dealer says the air conditioner is ok as air coming out of ducts is 3 degrees as required. I believe a larger a/c is required.

After a cooling cycle, when the thermostat call for more cooling, it take up to 5 minutes after the air handler starts for the compressor motor to restart. The top fan operates on the outside unit, but since the house is not circulating cold air, only the room tep air the house heats up about 3 degrees before the compressor comes back on and cool air begins to come from the ducts. Yes. I know there is a safety feature to protect the compressor, but can the cycle be shortened?

I have a Dometic 15,000 btu, ducted air conditioner in my 30 ft fifth wheel. It seems like the unit has never cooled very efficiently. Dealer has checked out.

Fan would continue running. Any suggestions?
