Many heating/cooling ducts are metal so they conduct noise rather easily from the air-handling unit to your rooms. To break the conduction of sound, you can have a heating professional insert flexible insulation ductwork between the heating/cooling system and the ductwork runs. If 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 hear it, make a little dent in the sheet metal to provide a more rigid surface thats less likely to move as it heats and cools Profile .
When room temperatures swing more than about 3 degrees F. between when the air conditioner goes off and on again, it typically suggests that the pump is not cycling on often enough. When room temperatures drop lower than the set temperature on the thermostat, it typically means that the thermostat is poorly calibrated or set up where it doesnt sense a proper sampling of room air.
You may be able to repair your air conditioner on your own. Here are some things to consider before you call an air conditioning repairman to ensure you do not get an $80 or $100 fee for a minor product. These are all simple actions that any homeowner can take to find and repair a minor AIR CONDITIONING issue that is keeping your system from cooling.
Many people think that by turning their systems off and allowing their houses to get hotter throughout the day, they are causing their systems to run less and are therefore, saving money, but, this is not the case. The issue is that air is not the only thing that heats up when you do this; furnishings, carpeting, walls, etc. will also warm up. When you get home and turn your air conditioner back on, it actually has to work harder and longer to get rid of all the extra heat and bring the temperature down to a comfortable level.
Keep your doors and registers open as much as possible. An appropriately set up and balanced air conditioning system is made to provide and return hot or cold air equally to and from all spaces in your home. Closing doors and supply vents, however, can disrupt this balance and cause particular spaces to become hotter or colder than others, resulting not only in discomfort, but also in decreased efficiency. It also causes air pressure to increase in your ductwork, which can potentially cause or multiply air leaks, again reducing the effectiveness.
Doors to unused rooms can be closed as long as there is enough space under the door to allow for air circulation; thick carpeting which brushes against the bottom of the door creates a seal of sorts. If you do choose to cut off a few of your supply registers, never cut off vents to more than 10 % of your total conditioned space.
