Duct Work Troubleshooting Tips for common issues
The following are some simple troubleshooting measure any homeowner can read to help determine if they have any issues that may need further attention.First off you will need to replace your air filters and make sure all supply registers are open throughout the home. This will ensure that your are operating at maximum air flow rates for your system design.
Turn on the blower, normally this can be accomplished by switching the fan on alone at the thermostat. Or you can turn off the power at the air conditioner and adjust your thermostat to call for cooling, either option will run the blower at high speed if the furnace or air handler is set up properly at the furnace or air handler.
If you find that your supply registers whistle or have noisy air flow throughout the home then this is a possible indication that the supply duct work is sized too small or there are not enough supply registers. for your system. Simple calculations from a qualified HVAC contractor can make the final determination.
If you find that your supply registers whistle or have noisy air flow only in a few areas in the home then this is a possible indication that the supply duct work may have some sort of blockage if the general areas are common to one are of the home but not necessarily near the furnace or air handler. Inspect the duct work for kinked or collapsed ducts.
If these noisy areas are all close to the furnace or air handler this may be an indication of improperly sized duct work as most of the air flow is being forced to flow through the shorter duct runs. This can easily be repaired using volume dampers inside the duct work adjusting for air flows. A qualified HVAC contractor can help make the final determination on where the dampers should go.
A noisy return grille is also an indication of improperly sized ducts or improperly sized return grille. Noisy furnaces and air handlers that whistle or sound like a wind tunnel are also an indication of improperly sized duct work or grilles. For more information on proper sizing of duct work as far as an industry standard rule of thumb check out our article on duct sizes.

  What
should I Look for Before I call for services on my air conditioning
system? The number one issue we find on air conditioning systems is
clogged filters. First look to see if your air filter is clean and not
clogged up, if it is clogged change the air filter and try your system
again but keep in mind with the air conditioning system running with a
clogged air filter you could have also iced up your indoor coil due to
low air flow.

  Why
does my Air Conditioning run all day in hot weather? Assuming this is
not a new symptom... this is a common complaint and can be attributed to
two possible things. The first is that your system may have been
designed correctly to meet the latest energy codes to perform at the
highest efficiency. The other possibility is that it was not designed at
all or was not sized properly in the first place. |
  Things you can do to maintain your air conditioning system. You can keep the outdoor air conditioner clean. You can
vacuum out the inside of the unit and get all those leaves and stuff
out. On most units you can gain access through the service panel. Be
sure the power is off before opening the panel. Be careful not to knock
off any wires and do not hit the coil as you will cause permanent
damage.

  In
the case of the thermostat calling for cooling the thermostat switches
on the power from the “R” or in some cases the “RC” terminal which is
the 24 volt power source to the “Y” terminal on the thermostat which is
in essence the call for cooling. These terminals are located on the back
or on the wall mounted face plate of the thermostat. All the wires
connected to the thermostat will usually always go directly to the
furnace and another set of wires will then go out to the outdoor air... |
